Description

Wearable physiological sensing device and system

The present invention relates to a wearable physiological sensing device and system, and more particularly to a wearable physiological sensing device and system having a plurality of wearable structures.

Traditionally, the electrical activity of the brain measured by placing the electrodes on the scalp is called an electroencephalogram (EEG). The EEG can be used to detect and diagnose many physiological conditions, and the obtained brain is obtained. Activity information can also have many other applications, such as learning concentration, fatigue, and brain computer interface (BCI).

In general, there are two ways to measure brain electrical activity, including reference montage and bipolar montage. In the reference combination paradigm, the brain electrical activity in the same position is used as a reference. For example, it is common to set the reference electrode to a position where there is no electrical activity of the cerebral cortex, and the activity detecting electrode is obtained with respect to the reference electrode. Brain waves, and the bipolar combination paradigm is to obtain brain waves through the potential difference of brain electrical activity at two locations.

However, the traditional brain electrical activity detecting device does have the disadvantages of being cumbersome, complicated in wiring, requiring a professional to assist in setting electrodes, and is difficult to generalize. Therefore, in order to solve these problems, various improved forms have been gradually developed, and one of them has been developed. It is a brain activity detecting device in the form of an ear.

For example, Looney D, et al., "The in-the-ear recording concept: user-centered and wearable brain monitoring." IEEE PULSE, 2012 Nov-Dec; 3(6): 32-42. The way in which the EEG signals were obtained from the ear canal also confirmed that there were similar waveform changes between the EEG signals obtained from the ear canal and the EEG signals obtained from the temporal area; in addition, many patent documents revealed The ear serves as a means for taking the position of the brain signal. For example, US20070112277 discloses the use of earplugs in the ear canal as the setting medium for the brain electrical electrode; US20120209101 discloses the use of an ear-shaped hearing aid as a medium for setting the brain electrical electrode; US8565852 discloses the cooperation through the earloop structure. The manner in which the ear clips achieve a fixed electrode effect; US20060094974 describes the idea of using an auricle structure to provide an electrode; and US7197350 and US8781570 use an earmuff as a medium for setting electrodes.

However, since the space inside the ear canal is very narrow, not only the electrode positioning is not easy, but also the preparation of the sampling device becomes very complicated, and it is not easy to implement. Moreover, there is a sampling problem in the ear canal, ear wax, The ear wax in the ear canal is a naturally occurring substance of the human body, which reduces the contact area between the electrode and the skin of the ear canal, and is even completely isolated. It is not easy to achieve good contact between the electrode and the skin, so it needs to be worn before each wearing. Special cleaning is actually a rather cumbersome procedure for the user.

Furthermore, when the position of the electrode is within the range of the auricle and the skull, since the range is close to the plane of the skull, the contact of the electrode with the plane must be fixed by the force directed toward the skull. However, the auricle has no structure in this range to provide the force applied in this direction. Therefore, how to fix the electrode has always been the most difficult problem to be overcome, and at the same time, care must be taken not to sacrifice the comfort of the electrode in order to maintain the stability of the electrode contact. .

For example, in US 2006/009497, a reference electrode It is placed on the earlobe by the conventional clamping method, and the detection electrode is fixed by the physiological structure of the auricle. Although this method is good, it is obviously completely lacking in fixation. Strength, the detection electrode is actually difficult to fix because of this, the contact between the electrode and the skin is quite unstable, and it is easy to shake due to the rotation and movement of the head, which directly affects the quality of the obtained signal.

In addition, in US8565852, in order to fix the detection electrode to the space between the triangular fossa and the cruc of helix and the superior crux of anthelix, and to make the electrode The special shape of the jig is used to contact the head in the space. However, for the user, it will be easy to feel uncomfortable due to the strength of the clip for a long time. Furthermore, this document also provides Another way to maintain the detecting electrode in the position to be contacted through the earloop structure, but it can be found that the electrode is still prone to sloshing due to the inability to provide the force directly applied to the electrode, and therefore, between the skin and the skin. Contact can't be stable for a long time, which will naturally cause the signal quality to decrease.

In US 2012/0209101, although an ear-shaped hearing aid is used to carry the electrodes and ensure contact between the electrodes and the ear canal and auricle skin, in such a manner, the fixed force mainly comes from entering the ear canal portion and the ear canal. The friction, and the shape of the hearing aid and the pendant extending to the back of the ear are only used for positioning. The electrode outside the ear canal lacks the direct fixed force. Therefore, as long as the ear canal is loose between the ear canal and the ear canal, the electrode will Deviation from the surface of the auricle skin is still prone to unstable electrode contact.

In addition, in US20070112277, in addition to the embodiment relating to the placement of the electrodes in the ear canal, it is also disclosed that the electrodes are placed on the surface of the behind-the-ear housing to contact the skull. This is a very common setting and contact position in the ear-worn brain activity detecting device. However, such a structure does not easily cause the rear ear shell to generate a force toward the skull, so usually the rear ear shell is only maintained. After the ear, it is very easy to shake, and the contact between the electrode and the skin is not stable.

Recently, it has been developed to use 3D scanning to enable each user to have an in-ear device that fully conforms to their own ear type. For example, US2015/016996 describes the formation of an ear-shaped device through 3D scanning technology to set Sensors, and United Sciences even provides a tour service for ear scans, and the program that is so cumbersome and costly is to make the physiological sensing components stable and unaffected by movement. In the ear to get high quality signals.

Therefore, it can be seen from the above that in the field of ear-wearing devices with physiological sensing elements, in order to solve the problem of how to make the physiological sensing elements reach a more stable setting, how to solve the above-mentioned problems exist in the known technology. The various problems are indeed an important topic in the field of current ear-mounted brain activity detection devices.

In the process of finding a solution, in addition to the position that is often used to obtain EEG signals, the applicant found a new EEG sampling position, which is prominent in appearance outside the skull and supported by the ear cartilage. The auricle part, and further through experiments, the signal strength of the EEG signal obtained on the auricle is sufficient for relevant EEG signal analysis and provide information on brain activity.

Therefore, the purpose of the present invention is to provide an ear-worn brain activity sensor that differs from the prior art design in that it utilizes an in-ear housing that at least partially conforms to the shape of the ear boat and/or the ear cavity. The activity detecting electrode can stabilize with the concha wall of the auricle The contact is in turn, which is beneficial to obtain the brain electrical signal adjacent to the temporal region of the cerebral cortex.

Another object of the present invention is to provide an ear-worn brain activity sensor that utilizes an in-ear housing that at least partially conforms to the shape of the ear and/or the tragus between the tragus, such that the reference electrode thereon can be associated with the tragus And/or achieve stable contact between the incisions between the tragus, and then obtain an EEG signal together with the motion detecting electrode.

Another object of the present invention is to provide an ear-worn brain activity sensor that transmits a movable detecting electrode or a reference electrode on the extending member through a relative urging force between the ear front member and the extending member. Achieve stable contact with the skin behind the auricle, which is conducive to the acquisition of EEG signals.

A further object of the present invention is to provide a spectacle-type EEG sensor that achieves stable contact between the electrodes and the skin on the back of the auricle and/or near the ear through the lens structure to facilitate the acquisition of EEG signals.

A further object of the present invention is to provide a brain activity sensor, which further includes a light emitting element and a light receiving element to obtain physiological information about heart rate and/or blood oxygen, and thus as physiological feedback and/or breathing training. in accordance with.

A further object of the present invention is to provide a brain activity sensor further having an electrocardiographic electrode for obtaining an electrocardiogram, thereby providing ECG related information.

Another object of the present invention is to provide an ear-worn electrode structure that achieves a stable combination of an electrode and an ear canal through the arrangement of an elastic material.

Still another object of the present invention is to provide a brain activity sensing device that is integrated into a user's daily life by means of a combination with a headphone.

It is yet another object of the present invention to provide a brain activity sensing device having a wearable structure that is variably disposed on a neck or head to provide a versatile use.

It is still another object of the present invention to provide a wearable stimulation device that is configured to be supported by a spectacles structure or an earwear structure to provide mobility convenience.

First, please refer to Fig. 1, which is a schematic diagram of the position of the cerebral cortex in the skull and the position of the auricle. It can be seen from the figure that the cerebral cortex falls in the upper part of the skull, and the auricle (also known as pinna) It is located on both sides of the skull and protrudes beyond the skull. In general, it is separated by the ear canal, which is roughly inside the upper auricle.

The experimental results show that a good brain wave signal can be measured in the upper part of the auricle part, and the lower the EEG signal is, the lower the physiological structure of the head is, because the head corresponding to the upper auricle should be The inside is the position of the cerebral cortex, so in this case, through the transmission of the skull and ear cartilage, the brain wave can be measured in the upper part of the auricle, while the lower auricle is farther away from the cerebral cortex, plus The interval between the ear canal, therefore, the lower the EEG signal strength becomes weaker, so in this creation, in principle, the ear canal is the boundary, and the upper auricle is regarded as the measurable EEG signal. The position is suitable for setting the activity detecting electrode, and the lower auricle is regarded as the weak position of the EEG signal, so it is suitable to set the reference electrode.

Among them, a reference electrode setting position that needs special emphasis is a tragus, which in physiological configuration also belongs to the auricle portion protruding from the outside of the skull, and there is no cerebral cortex under the position, and in the experiment, this is The position is not easy to measure the EEG signal, and the structure is relatively independent, which is a particularly suitable reference electrode setting position.

Please refer to FIG. 2, which shows a comparison diagram of the EEG signals obtained by the electrode setting method of the present invention and the conventional scalp electrode setting method, wherein the upper image shows the movable detecting electrode disposed at the scalp above the auricle ( That is, in the traditional 10-20 system, the position of the T7/T8) The electrocardiogram obtained by the reference electrode is set on the earlobe, and the lower part is the electroencephalogram obtained by the movable detecting electrode disposed on the upper side of the same side of the auricle with the reference electrode disposed on the tragus.

As can be seen from the figure, the two have the same trend of change. Therefore, when the motion detecting electrode is disposed on the upper part of the auricle, the electroencephalogram of the temporal lobe area can be obtained by the electrode disposed on the scalp. .

Next, it is described how this novel electroencephalic electrode contact position achieves the effect of improving the disadvantages described in the prior art.

Please refer to Figure 3, which shows the internal configuration of the auricle. The auricle is the part of the ear that protrudes from the outside of the skull. It is mainly composed of skin covered cartilage. The earlobe (also known as lobue) at the lowermost position contains only subcutaneous tissue; the inner surface of the auricle (concave side ( The concave side)) includes various protrusions and recessed areas as shown in the figure.

According to the concept of the present creation, in the auricle structure, the skin surface having the cartilage portion, for example, the back side of the auricle (convex side), the inner surface of the auricle, etc., are the setting and contact position of the electroencephalogram electrode. In addition, the auricle is suitable for hanging and fixing because it protrudes from the skull. On the other hand, as shown in FIG. 3, the protrusions and depressions on the inner surface of the auricle are also suitable for setting and fixing. The electrodes, therefore, in conjunction with the novel sampling locations described above, will provide a more secure means of achieving stable electrode contact.

For example, in the inner surface of the auricle, around the superior concha 1001 and the inferior concha 1003, there is a concha floor (ie, a plane parallel to the skull). ) an upwardly connected area of the antihelix and the antitragus 1004, referred to as the concha wall 1002, of the ear The natural physiological structure provides a continuous elevation that protrudes from the bottom of the ear. Therefore, when this area is used as the electrode contact position, the force required to fix the electrode will be a radial force different from the conventional technique. That is, the force parallel to the bottom of the ear; in addition, immediately below the wall of the ear, the intertragic notch 1007 between the tragus 1004 and the tragus 1003, and the tragus immediately adjacent, A contact area is provided that protrudes from the bottom of the ear. Therefore, in the present creation, the armor wall, the tragus, the tragus between the tragus, and the continuous façade area formed by the tragus are particularly suitable for setting electrodes and achieving stable contact through radial force. The choice directly solves the problem that the conventional technique is always difficult to provide stable maintenance of the electrode toward the bottom of the ear.

Moreover, since the range of the façade region extends from the upper portion of the auricle to the underside of the ear canal, the region above the ear canal 1005 can serve as the contact position of the motion detecting electrode according to the experimental results mentioned earlier, for example, The ear arm wall above the ear canal, and the area below the ear canal 1005 is the contact position that can be used as the reference electrode, for example, the ear arm wall below the ear canal, the ear arm wall near the tragus, the tragus, the tragus The incision, as well as the tragus.

The advantage of this is that in the narrow space of the same ear, the setting of the reference electrode and/or the motion detecting electrode can be completed, and the reference signal combination can be effectively used to obtain the EEG signal, completely rid of the A limitation of the prior art, that is, the reference electrode is usually only disposed on the mastoid bone or on the earlobe, and the motion detecting electrode must be placed at a position above the skull corresponding to the cerebral cortex, and the pair of wearing forms The physiological detection device is undoubtedly a major breakthrough in the feasibility and ease of operation, because not only the device volume can be minimized, but also the wiring complexity can be simplified, so that the user has the best experience.

Here, it is necessary to pay special attention to the fact that, due to the smooth curve change between the protrusion and the depression in the actual physiological structure of the inner surface of the auricle, rather than the right angle change, there is no obvious between the above-mentioned elevation area and the bottom of the ear. The right angle boundary, but the two are connected by a curvature change, therefore, in this case, the contact position of the electrode, in addition to the elevation area, will also contact the curvature change according to the structure of the electrode contact. Unlimited.

In addition, it should be noted that in the measurement of EEG signals, in addition to the reference electrode and the motion detecting electrode, grounding electrodes are often provided to suppress the common noise, but some are also used. The circuit design can eliminate the need to set the grounding electrode and can be selected according to actual needs. Therefore, based on the principle of simplifying the description, the description of the grounding electrode is omitted in the following description, but in actual implementation, the brain activity sensing according to the present creation is performed. The device and the sensing device can also be provided with grounding electrodes according to requirements, without limitation.

When the main surface area is contacted, the in-ear housing that can be placed on the inner surface of the auricle will be the primary choice, and there is no limitation as to what shape and form to use, as long as it can be used with the elevation area. A stable contact can be achieved. For example, FIGS. 4a-4c illustrate a schematic view of the in-the-ear housing 10 in combination with the inner surface of the auricle according to the preferred embodiment of the present invention, which respectively shows the in-ear housing 10 in the ear wall. The contact with the otoscope, the tragus between the tragus, and/or the area formed by the tragus contacts all, the upper half, and the lower half of the façade.

Here, in particular, in the present creation, the in-the-ear housing is preferably fixed by a radial mutual abutment between the armor boat and the structure around the ear canal, and due to the electrode contact position -- - the ear wall, the tragus, the tragus between the tragus, and / or the tragus - that is, around the ear boat and / or the ear cavity, so that the inner casing can be fixed at the same time Achieve stable electrode contact.

In one embodiment, the shape of the inner ear shell is implemented to conform to the ear canal and the ear cavity. In this case, the electrode can be easily touched to the preset position, and the installation is the easiest; another embodiment Yes, the specially designed in-the-ear housing shape is adapted to suit each individual's different auricle shape and size through simple operation. For example, as shown in Figures 5a-5b, the in-ear housing is implemented. In order to adapt to different auricle sizes through a simple rotating action, and to achieve abutment fixation, in this case, one electrode 102 can be placed at a position near the contact tragus as a reference electrode, and the other electrode 100 can be set. a distal end position on the inner casing of the ear opposite to the position of the tragus, or a position disposed at the bottom of the ear inner casing facing the bottom of the ear (as shown in Figures 6a-6b) as a motion detecting electrode, such In this way, the contact of the electrodes can be achieved while achieving the fixation. Since the contact position of the inner ear shell in different auricles may be offset (as shown in FIGS. 5a-5b), it is preferable to form the electrode 10 so as to cover a continuous range of a large range of movement. To ensure the reach of contact.

As can be seen from the above, the common types of earphones on the market are suitable for the concept of the present creation. As is well known, when the earphone is placed in the inner surface of the auricle, it will naturally touch at least the tragus, the tragus between the tragus, or For the position such as the tragus, and then depending on the actual shape, it is determined whether there is contact with the arm wall, so that the electrodes can be placed at these positions, and when the earphone has a portion extending into the ear canal, Increase the fixation effect to help maintain stability in the inner surface of the auricle.

Therefore, similarly, the inner ear shell of the present invention can be similarly selected when implemented, and can be fixed only by the radial abutment between the shell and the façade area, and can also be added to the ear canal portion. To increase the fixed effect, and further, the portion that enters the ear canal can also be Used to guide the sound into the ear canal when there is a sound providing function.

In addition to the fact that both electrodes are implemented to contact the above-mentioned façade region, one of the electrodes may be in contact with other locations. For example, when the in-the-ear housing is configured to have a portion that enters the ear canal, the electrode can be placed at a position that will contact the tragus, and a position that is opposite to the tragus across the ear canal, that is, the ear canal The bottom is connected to the ear canal near the turning point, as shown in Fig. 6a, so that the effect of stable contact is achieved by the radial force, and the advantage of such a contact position is that as long as the entry into the ear canal portion Being able to be set up steadily is equivalent to completing the electrode setup, which is not only convenient but also extremely easy to achieve.

In another preferred embodiment, one of the electrodes may also be placed in a position to be in contact with the bottom of the ear, as shown in Figure 6b, in which case the inner casing of the ear has penetrated the radial force. Having one of the electrodes in stable contact with the façade region and thus being fixed in the auricle, the relative displacement that may occur between the inner canal and the ear has been minimized, in which case the ear is facing The position of the electrode at the bottom of the cavity will be fixed to a certain extent, and it is not easy to move. It is also a very advantageous contact mode. For example, the various ear inner casings shown in Figures 4a-4c and 6a can be One of the electrodes is disposed on a surface that contacts the bottom of the ear.

In still another preferred embodiment, an electrode can be disposed on the surface of the entrance ear canal portion to contact the ear canal, wherein if it contacts the upward position in the ear canal, it can be used as an activity detecting electrode. Further, if the inner electrode of the ear canal is placed in a contact downward position, it can be used as a reference electrode, and therefore, various possibilities are possible.

There are various possible options as to how the electrodes are placed over the portion of the ear canal.

When the portion of the ear canal is provided, as shown in FIG. 7a, the inner casing of the ear is configured to extend out of a support body 12, and an elastic member 14 is disposed on the support body, and the elasticity of the elastic member is transmitted through the elastic member. The restoring force can be easily placed in the ear canal due to compression, and can be stably maintained in the ear canal due to the elastic restoring force after entering the ear canal. In addition, when the earphone function is combined, the supporting body can be implemented as It has a hollow passage to allow sound to pass through the ear.

Therefore, when the electrode is to be disposed, it is preferably disposed on the surface of the elastic member 14, so that the electrode can be easily secured into the ear canal, and can be naturally stabilized by the elastic restoring force of the elastic member. Ground contact with the ear canal is a very advantageous choice. As for the way of setting, there are various possibilities.

For example, as shown in Figures 7a-7b, electrodes may be attached to the surface of the elastic member, such as thin metal, conductive fibers, etc., and in this case, it is considered to be located in the elasticity. How the electrode 100 of the component surface is electrically connected to the circuitry 104 located in the in-ear housing. In a preferred embodiment, the surface of the support 12 is implemented to have a conductive portion 121 for achieving a connection between the electrode 100 and the circuit 104 through the conductive portion, for example, as shown in FIG. 7a. The connecting electrode can be used to connect the electrode 100 and the conductive portion 121, and the conductive portion 121 and the circuit 104 are connected; or the conductive portion 121 and the electrode 100 can be connected by different methods, for example, As shown in FIG. 7b, a conductive substance 142 which is in contact with both at the same time can be disposed between the two, and the electrical connection effect can be achieved, and the manner of maintaining the contact between the electrode and the ear canal is more helpful. , quite advantageous. It should be noted here that although only one electrode is shown in the drawings, it can be implemented as more than one electrode.

In this case, there is a special implementation, that is, the electrode and the guide The electric material is made of the same conductive material, that is, the two can be integrally formed. Thus, as shown in Fig. 7c, the elastic member is formed by combining two materials, the elastic material portion 143 and the conductive material. The portion 144, wherein the portion formed of the conductive material is simultaneously used as the electrode and the conductive portion, and the portion formed of the elastic material serves as the body of the elastic member to provide an elastic restoring force to ensure the conductive material portion 144 and In the case of the ear canal contact; in this case, if the conductive material is also selected to have elasticity, for example, elastic conductive rubber, elastic conductive silicone, elastic conductive foam, etc., the elastic member is still elastic as a whole.

In addition, in another preferred embodiment, the support body can be directly implemented as an electrically conductive material, so that the support body can be regarded as the conductive portion as a whole, and further The implementation is more simplified.

Therefore, in a preferred embodiment, as shown in FIG. 7d, the support body can be directly formed to have a protrusion 122 instead of the conductive material portion, so that when entering the ear canal, The exposed surface of the protrusion can be regarded as an electrode to contact the ear canal, and in this way, since the elastic member is mostly composed of an elastic material except for a small portion of the convex position, The elastic restoring force can ensure the contact between the protrusion and the ear canal is stable, and as long as the area of the protrusion is appropriate, even if it is made of a relatively hard material, it will not feel uncomfortable; here, it should be noted that Alternatively, as shown in FIG. 7e, it is possible to provide the electrode 100 on the surface on which the bump is exposed without using a conductive material to form the support body, which is a feasible manner, and thus is not limited.

Another implementation may be to directly form the elastic member by using a conductive material, such as conductive rubber, conductive silicone, conductive foam, etc., so that the support is made of a conductive material. If it is formed, it only needs to be connected to the circuit again, or if the support has a specific conductive portion, it is only necessary to determine that the contact between the elastic conductive member and the conductive portion is stable, no matter what The way is quite convenient. In addition, a conductive fiber can be coated on the outer surface, in addition to making the contact with the skin more comfortable, and the service life can be improved. For example, materials such as rubber and foam may appear on the surface due to frequent users. The phenomenon of falling off is also quite advantageous. Such a design is particularly suitable for the method of performing brain wave measurement by simultaneously setting electrodes on both ears, because when the EEG signal is obtained through both ears, since the distance between the ears is sufficient, the contact position of the electrodes is not limited, even if the whole The surfaces of the elastic members are all electrically conductive and have little effect on signal extraction.

Furthermore, if the electrode has a specific contact position, for example, the upward position as the motion detecting electrode or the downward position as the reference electrode, the outer surface of the conductive elastic member may be coated with a non-conductive material. By way of example, as shown in Fig. 8a, the outer surface may be coated with an insulating coating 145 to expose the position to be contacted as an electrode. In such a design, the elastic member is made of only one material. It is not necessary to combine with different materials, and only need to increase the step of coating the insulating layer, so it is not only easy to manufacture, but also easy to implement, and it is also an advantageous way.

Still another implementation may be that the conductive elastic member is implemented to have two portions, a first portion 146 and a second portion 148 as shown in FIGS. 8b-8c, and the two portions are mutually connected by an insulating portion 147. Electrical insulation, in this way, equal to the same elastic component can also provide two mutually insulated conductive regions, so when actually applied to the measurement, one of the implementation options can be that the outer surface is covered with an insulating coating, and respectively Exposing the first part in the first part and the second part The conductive region and the second conductive region serve as two electrodes. Alternatively, the conductive material may be disposed on the surface of the first portion and the second portion, for example, a metal conductive sheet, or conductive. Forming the first electrically conductive region and the second electrically conductive region in a manner of fibers or the like, wherein the first portion and the second portion function as the conductive substance 142 as described above, and thus, according to actual measurement requirements And there is no limit to choice.

On the other hand, it is also possible to implement the form without the support body, and in such a manner, the user's use comfort can be further improved, and when implemented, it can be located on the surface of the elastic member as shown in FIG. The electrode 100 is connected to the conductive portion 121 by a connection line 141, and the conductive portion 121 is connected to the circuit 104, and various forms as shown in Fig. 7b, Fig. 7c, Fig. 8a, Fig. 8b, and the like. The elastic members can also be implemented in the form without a support, without limitation.

Furthermore, in the case of using two in-ear housings, it is also possible to implement the form in which the electrodes on both sides contact the bottom of the ear, respectively, and fix the in-ear by using the radial force between the inner housing and the auricle. After the housing, the electrode toward the bottom of the ear can stably reach the skin, which is quite convenient in implementation and operation, especially when the two electrodes are divided on the two ears, compared to the set On the same in-ear housing, the contact position of the brain wave can be made less restrictive, and it is naturally easier to operate.

There are many possible ways to achieve a topping to ensure electrode contact. For example, it can be achieved by selecting the material of the inner ear shell, for example, using an elastic material to make an inner ear shell slightly larger than the range of the armor boat and/or the ear arm cavity, so that the inner ear shell is When placed, the elastic material can be subjected to the elastic restoring force generated by the compression to achieve the effect of the topping.

When the inner casing of the ear is selected to be formed of a resilient material, it can be implemented such that the entire inner ear casing is made of an elastic material, and the electrode is disposed at a specific position on the surface, for example, a position at which the elevation region can be contacted, and Further, the elastic in-ear casing may be formed to have a hollow portion. In addition to increasing compressibility and deforming force, part of the circuit component may be disposed in the hollow portion, for example, when implemented as a headphone function. The sounding element can be placed in the elastic in-ear casing.

In this case, similar to the elastic member placed in the ear canal, a conductive region can be formed on the surface as an electrode. For example, the electrode can be disposed on the surface, or can be achieved by combining different materials, or It is also possible to form the inner ear casing directly by using an electrically conductive elastic material, and to cover the electrode contact position by externally covering the insulating layer, which is an implementable manner; and the position of the electrodes is not limited to one, and at the same time There are two electrodes, for example, one as the motion detecting electrode and the other as the reference electrode, which are not limited; moreover, as described above, if implemented as a two-ear inner casing, the position of the electrode contact may not be limited, for example, the ear The inner casing can be simply implemented by a single elastic conductive material, which not only achieves physiological signal extraction, but also achieves the effect of elastic topping, which is quite convenient.

In addition, the elastic in-the-ear housing is also preferably formed to have a portion that enters the ear canal, that is, has a portion that enters the ear canal and a portion that is outside the ear canal and engages with the concave and convex structure on the inner surface of the auricle, thus, In addition to better fixation, the choice of electrode placement is more diverse. For example, one electrode can be located on the part that enters the ear canal, the other electrode is on the part outside the ear canal, or both electrodes are located outside the ear canal. Partially, or both electrodes are located on the portion that enters the ear canal, without limitation.

On the other hand, alternatively, the in-ear housing can be radially biased by providing a contact securing structure. For example, as shown in FIG. 10a, the in-ear housing can be implemented as an elastic material. The hollow portion 16 is such that the shape of the inner casing can be freely expanded and contracted according to the shape of the inserted space, and can be adapted to different ear shapes of different users, and the electrode 100 located thereon can be Stabilizing contact with the inside of the auricle; in addition, the contact ensuring structure can also be implemented in other forms, for example, a spring mechanism, a resilient button, and an elastic extension member, etc. In particular, the position of the abutment can also be designed to occur directly at the position of the electrode, and to ensure the stability of the electrode contact, as shown in Figures 10b-10d, which show three forms of protrusion on the surface of the inner casing of the ear and Forced and contracted electrode protrusion, wherein FIG. 10b shows that the metal electrode 100 can independently expand and contract and pass through the in-ear housing, for example, a spring-loaded electrode, wherein common One form is a spring pogo pin, and the 10th figure shows that the electrode 100 is embedded in the surface of the inner ear casing but has a compressive restoring force, and the 10th figure shows that the display electrode 100 is located on the elastic extending member 18, The force of the electrode against the arm wall can be provided by adapting the shape of the arm wall, wherein the end of the extension member can be abutted, or the entire extension member surface can be abutted along the arm wall, regardless of In any case, it is advantageous to more accurately stabilize the contact between the electrode and the skin. Therefore, the embodiment is not limited, as long as it conforms to the shape of the ear ergonomics and can be fixed in the ear canal and/or the ear cavity through the radial abutment. category.

Alternatively, the contact securing structure can also be implemented directly on the electrode 100. For example, as shown in FIG. 11a, one electrode may be formed as a plurality of dispersed contact points, for example, in parallel with each other, so that no matter which contact point is touched, it may be regarded as an electrode and a skin. The inter-contact has been completed, which is quite convenient, and this is particularly suitable for a contact surface having a curvature or a slight movement, and it is further advantageous if each of the dispersed contact points can be implemented as having The scalability, for example, as shown in Fig. 11b, is in the form of a spring ejector to further ensure the achievement of contact, for example, the contact between the skin and the electrode is achieved by compressing the spring thimble, such that Even if a small distance displacement between the skin and the electrode occurs, it can be overcome by the elastic elasticity of the spring thimble.

In addition, as shown in FIG. 11c-11d, it may be implemented in the form of a plurality of protrusions on the same electrode member 100. For example, the electrode sheet may be directly formed to have a plurality of protrusions, or may be implemented as The electrode sheet has a plurality of retractable projections and the like, which may be in various forms, which also contributes to an increase in skin-to-electrode contact.

Furthermore, the electrode may also be implemented in a suspended form. For example, as shown in FIG. 12, a telescopic structure, such as a spring thimble, is disposed under the electrode, so that the electrode may have a vertical direction in response to a change in the contact surface. In addition to the telescoping, the angle change can be made by using the lower spring thimble as a fulcrum, which is quite helpful for adapting the shape of the auricle; and further, the surface of the electrode in suspension form can also be formed with protrusions, for example, In conjunction with the implementation of Figures 11c-11d and 12, it is easier to achieve contact.

Here, it should be noted that the above-mentioned mechanism for achieving the apex can be implemented at any position in the inner casing of the ear, for example, it can be a contact tragus, a tragus, a bottom of the ear, an arm wall, and/or The position between the tragus and the like is not feasible, and is not limited to the position where the electrodes are disposed. Further, two or more kinds of abutting mechanisms may be simultaneously used to further ensure the achievement and maintenance of the contact, and thus, there is no limitation.

In addition, the in-ear housing can be implemented to have different sizes for the user to select based on different ear sizes between different users, or by replacing the sleeve member covering the inner housing of the ear, for example, The rubber sleeve is modified to change the overall size of the inner casing to increase the cost effect. At this time, preferably, the electrode is configured to penetrate the surface of the inner casing and expand and contract as described above, so that Even if the sleeve member is replaced, the position of the electrode and the contact with the skin are not affected, or the size of the ear inner casing can be changed to achieve different sizes, for example, only the sleeve is placed around the retractable electrode. Part of the inner ear housing does not need to be replaced at the same time, which is also cost-effective. Of course, it can also be implemented to replace the part with the electrode, and the material of the sleeve part can also be changed according to requirements, for example, silicone rubber, rubber, Materials such as foam are good choices, and further, through the choice of materials, the effect of the buffer effect can be achieved, which is quite advantageous. Therefore, there are various possible ways, and are not limited to the above.

Accordingly, in a preferred embodiment, the in-ear housing is implemented as shown in Figures 13a-13d, that is, the in-ear housing 10 is permeable to the sleeve member 20 of the extension member 22. The shape and size of the inner surface of the auricle that can be adapted to it can be different. The size and shape of the inner casing that can be placed in the ear are different, so that different thicknesses, shapes and materials are provided through replacement. The sleeve member, the extension member of different shapes, and the flexibility of the extension member itself can be adapted to the various auricle sizes and shapes as much as possible. Here, it should be noted that the electrode can be implemented without the sleeve. The components are replaced, for example, by using spring-loaded electrodes as described above to overcome the thickness of the sleeve components, or also to be formed directly on the sleeve components, as shown in Figure 13a, and in the casing. Electrical connection to the electrically conductive contact portion of the housing when in the body is an implementable manner and is not limited.

In the embodiment shown in Figures 13a-13c, the extension member can abut the arm wall above the ear canal, and as can be seen from the figure, in actual implementation, the shape of the extension member can have various possibilities, for example, The extension member of Fig. 13a has a finer and better flexibility, and the extension member of Fig. 13b has a better supporting force because of the wider width, or a ring as shown in Fig. 13c. Therefore, there is no limit.

Alternatively, the extension member may be disposed at other positions. As shown in FIG. 13d, the extension member is disposed under the housing and is formed by changing the thickness and shape to the ear arm wall below the ear cavity (ie, The abutment between the otoscope and the extension member may be disposed at a position contacting the tragus or at a position of the arm wall portion opposite to the tragus. Therefore, the extension member may further Ensure that the inner ear housing is stably maintained in the inner face of the auricle.

Wherein, in particular, the extension member can be further configured to have a tilt toward the bottom of the ear, in addition to providing a radial abutting force parallel to the bottom of the ear, and through such a design, when the extension member is disposed When the inner surface of the auricle is reached, in addition to the position of the ear wall, the tragus, the tragus, etc., the component of the auricle will also have a component force toward the skull direction, thereby further making the ear The inner casing is more stably maintained in the auricle face.

Further, the extension member can also be implemented at a position of the inner ear shell toward the bottom of the ear, for example, an elastic protrusion toward the bottom of the ear to achieve contact with the bottom of the ear, which is particularly suitable. The situation where the electrode contacts the bottom of the ear.

Here, in particular, as shown in Fig. 3, the physiological structure of the auricle will have a separation protrusion between the ear boat and the ear cavity, and when the extension member is subjected to the upper arm wall of the ear boat When in position, especially when there is a tilt to provide a component force toward the skull, the upper inner casing The edge will naturally contact the separation projection, which will greatly assist in achieving contact between the electrode disposed at this location and the bottom of the ear.

On the other hand, when the electrode is implemented to be disposed on the sleeve member, it is particularly suitable for being disposed on the extension member. Since the extension member mainly lies in abutment with the elevation region, the electrode is disposed on the extension member. In the above, the contact between the electrode and the skin can be stabilized by the force of the topping, for example, the extending member that contacts the upper arm wall, or the extending member toward the bottom of the ear, is a position suitable for setting the electrode.

Moreover, without limitation, in actual implementation, the various embodiments described above may be assembled according to different contact positions of the electrodes to meet different implementation requirements. For example, when an EEG signal is to be obtained through a single ear, it can be attached to the pinna with an upwardly extending member (as shown in Figures 13a-13c) and a downwardly extending member (as shown in Figure 13d). Inside, in this case, the setting of the reference electrode can be selected to contact the tragus, or the ear arm wall near the tragus (through the downward extension member), and the setting of the motion detecting electrode can be selected to contact the upper ear of the ear boat A wall (through the upwardly extending member), or the bottom of the ear, wherein the contact with the bottom of the ear can be directly disposed on the surface of the inner casing of the ear, or can be achieved by extending the member toward the bottom of the ear.

In addition, when the EEG signal is obtained through both ears, since the distance between the ears is sufficient, the contact position of the electrodes is not limited, and the main focus is on allowing the inner ear shell to be stably maintained on the inner surface of the auricle, and the electrode Stable contact can also be achieved between the skin and the skin. For example, both ears can be contacted with the bottom of the ear, or the electrode can be contacted with the ear wall, the tragus, or the tragus, etc., depending on actual needs. Combination, no limit.

In addition, in particular, it can also be implemented that the inner ear shells on both sides have two electrodes. a reference electrode and a motion detecting electrode, and then, through two sets of reference electrodes and active detecting electrodes respectively located on different ears, can obtain two channels of EEG signals, or set the reference electrodes to A two-channel EEG signal can also be obtained on a single-sided in-ear housing, which can be used, for example, to monitor the activity of the left and right brains, and is also a highly advantageous embodiment.

It can be seen from the above that the inner ear shell is intended to be stable in the inner surface of the auricle, mainly to achieve at least two or more abutments, for example, a fixing force generated by entering the ear canal portion, plus a portion not entering the ear canal portion. The abutting force at the upper ear arm wall, and/or the lower ear arm wall, and/or the tragus; or the abutting force at the upper ear arm wall without entering the ear canal portion, and the tragus And/or the abutting force at the lower arm wall, etc., therefore, in the implementation, as long as it is a suitable abutting position to achieve the radial abutting force, and can maintain the contact between the electrode and the skin of the auricle, it is the case The claimed content is not limited by the specific embodiments described above.

By way of further example, the back side (convex side) of the auricle is also a location that is quite suitable for sampling, and when used as a sampling position, a hook-type will be the primary choice. In this creation, unlike conventional techniques, the electrodes located on the back of the ear are in contact with the back of the ear rather than the most common skull.

In general, the implementation of the ear hook form usually has a component in front of and behind the auricle, and the effect of fixing the auricle through the interaction force between the two is to maintain the ear. The contact between the posterior component and the skull is not easy. In contrast, the contact with the back of the auricle is easier to achieve, and this situation is in line with the novel contact position proposed by the present creation.

As shown in Figures 14a and 14b, an earhook structure according to a preferred embodiment of the present invention, and a schematic view of the earhook structure in combination with the auricle, the earloop structure shown herein includes an ear front member 60. Preferably, the in-ear housing, as previously described, and an extension member 62 extend upwardly from the ear front member 60 across the auricle to the auricle back (convex side) with Having a relative force to ensure that the earloop structure can be stably maintained on the auricle, and the electrode is disposed at a position on the extension member that can contact the skin behind the ear, so that the contact between the electrode and the skin can be Naturally, it is stabilized by the relative urging force between the ear front member and the extension member.

Here, similarly, when the contact position falls on the upper part of the auricle, it can be used as a sampling point of the motion detecting electrode, and when implemented as a reference electrode, the contact position can be designed in the lower part of the auricle, and also The electrode can be placed on the front part of the ear to contact the inner surface of the auricle. For example, the electrode on the inner casing of the ear can be implemented as a half of the inner surface of the auricle to act as a motion detecting electrode or to contact the inner surface of the auricle. The half part is used as a reference electrode, or an electrode is placed on the ear canal portion to contact the ear canal, etc., and thus can be changed according to requirements, and is not limited.

There are also various possibilities as to how the relative force applied between the front part of the ear and the extended part can be achieved. For example, the design of the structure may cause a misalignment between the extension member and the front part of the ear to naturally exert a force on the ear; or, a pivoting structure may be adopted at a portion where the two are connected, wherein the pivot shaft may be implemented Parallel to (bottom 14a), or perpendicular to (figure 14c) the bottom of the ear, so that the extension member can exert a force toward the back of the auricle; or, the sliding structure can be used at the junction of the two 14d) so that the extension member can thereby obtain a force from top to bottom and toward the auricle.

In addition, the shape of the extension member can be designed to make it more conforming to the auricle back. The curvature of the surface can also increase the stability of the electrode contact; or the extension member can be made of an elastic material, and the contact stability of the electrode is increased by the elasticity of the material itself, for example, the elasticity is combined with the front part of the ear. The power of the auricle. Therefore, there are various possible implementations, without limitation.

Therefore, as long as the appropriate extension member and the appropriate relative force application mode are selected, the requirements of different electrode contact positions can be achieved, for example, the back skin corresponding to the position of the arm wall of the inner surface of the auricle, and the position near the earlobe. The skin on the back of the auricle, etc., are all easy to reach and reach a stable position, making it easy to manufacture and use.

In addition to the above-described position, there is a position where the extension member can be used to easily and stably achieve contact, that is, a V-shaped depression between the auricle and the skull, as shown in Fig. 15, the V-shaped depression is located in the auricle and Between the skulls, including the skull portion 901, the auricle portion 902, and the connecting portion 903 as a connection, thus forming a physiological structure that is just suitable for placing an object between the auricle and the skull, wherein when the object is placed in the region In addition to selectively contacting any of the three portions 901-903, the auricle and the skull naturally provide the force to sandwich the object, even when the object is of sufficient volume and/or shape. The object can also be embedded/plugged between the auricle and the skull for better fixation and, therefore, more selectivity in practical implementation.

Here, the electrode implemented on the extension member is also suitable for the contact securing structure as described above, for example, as a dispersion electrode, and/or an electrode in a telescopic form, etc., to accommodate the auricle back and/or V-shape. The shape of the depression, in turn, contributes to the maintenance of contact between the electrode and the skin.

The method of fixing the electrode may be in addition to the above-mentioned ear inner casing and the ear hanging form. There are other implementations.

For example, the fixation effect can be achieved by magnetic attraction, for example, the ear front part and the extension part can be magnetically attracted to each other across the auricle, and the same effect can be achieved. The component may be implemented to be magnetic or made of a material that is magnetically attractable, for example, one component may be implemented to have a magnetic force, and the other component may be magnetically attracted, or both components may be Implemented as having a magnetic force, there may be various implementation possibilities, without limitation. In addition, preferably, a part of the extension member is implemented as a soft material, for example, a connecting line, to increase the comfort of use; wherein, in particular, since the magnetic force is fixed, the extension member is not only upwardly spanned Extending over the auricle to the back of the ear, it can also be implemented to extend from below to behind the auricle, further increasing the choice of implementation.

Further, instead of using the clamp to achieve the above-described electrode arrangement using a magnetic force, the clamping force generated by the jig can simultaneously achieve the effect of maintaining the electrode position and stabilizing the electrode contact, and thus there is no limitation.

The advantage of using this type of method (fixed by magnetic force and/or clamping force) is that it can be adapted to different auricle sizes in a single size, which is quite convenient in production, and provides the possibility of changing the position of the electrodes. Maximize the value of use.

Furthermore, in particular, the electrode contact locations of the present invention are also suitable for implementation through the spectacles structure. Generally, when the glasses are worn, the natural contact position of the glasses frame includes, but is not limited to, the nose pads contact the nose bridge, the mountain roots, and/or the area between the eyes, the front section of the temples contacts the temples, and the rear of the glasses contacts the auricles. The V-shaped recessed area between the skull and the part of the temple that falls behind the auricle will contact the skin behind the auricle, and these positions are exactly what the case wants. The claimed electrode contact position, according to which the electrode according to the present invention is naturally suitable for implementation on the spectacles structure, and simultaneously completes the contact of the electrodes by the action of wearing the spectacles structure, which is also a relatively convenient choice, and, due to the structure and head of the spectacles The support position of the part includes at least two contact positions of the auricle and the nose, and can be stably disposed on the head without swaying, thereby naturally generating a stable force for the contact between the electrode and the skin. A fairly advantageous implementation.

The spectacles structure described herein refers to a wearing structure that is placed on the head by the auricle and the nose as a supporting point and that comes into contact with the skin of the head and/or the ear, and thus is not limited to a general spectacles structure. Also included is a deformation thereof, for example, a structure having a clamping force on both sides of the skull, or an elastic continuum without a pivot axis of the temple, as shown in Fig. 23d, or extending to the posterior occipital region of the brain. The structure of the temples may be implemented as an asymmetrical form of the temples, for example, one side of the temple has a curved portion behind the auricle, and the other side of the temple has no curved portion only above the auricle, or The strap connecting the two temples may also be provided for the purpose of increasing the fixing effect, and the lens may not be provided. Further, the nose pad is not limited to a specific form as long as it contacts the bridge of the nose, the root, and/or the area between the eyes. The parts are regarded as part of the nose pad. In addition, there is no limit to the position of contact with the head/ear. For example, some glasses are also used for contact with the eyes for practical use or styling, for example, VR glasses. Other parts around, so there are all kinds of possibilities, there is no limit.

In terms of material selection, in addition to the hard material of ordinary glasses, it can also be implemented as an elastic material, which not only increases the stability of the electrode contact, but also provides the use comfort. For example, the memory metal and the flexible plastic can be utilized. The material is formed into a frame, and/or elastic rubber, silicone rubber, etc. are disposed at the electrode contact position to make the contact more stable and unlimited.

There are also various possibilities for the manner in which the electrodes are combined with the eyeglass structure and the manner in which the required circuitry (eg, processor, battery, wireless transmission module (eg, Figure 26, 42), etc.) is set. For example, one of the ways is that, as shown in the 22th, 22c, and 22e diagrams, the required circuit is directly embedded in the spectacles structure, and the electrodes are directly exposed on the surface of the temples and the frame to be worn. Touch the skin of the skull and / or ears.

Another possible way is to achieve the electrode and circuit configuration through an additional structure. Here, preferably, the additional structure is implemented to accommodate at least part of the circuit, thereby simplifying the manufacturing complexity of the eyeglass structure. For example, as shown in FIG. 22b, the additional structure may be implemented to be electrically connected to the spectacles structure, and the electrode 202 thereon may be signal-extracted together with the electrode 200 on the spectacles structure, or, as in the 22d As shown, the additional structure can also be implemented to have two electrodes 200, 202 at the same time, and is disposed on the auricle through a combination with the spectacles structure, both of which are obtained by contacting the unilateral auricle. On the other hand, the additional structure can also be implemented in plural. For example, the bilateral temples are combined with an additional structure, and the signals are extracted through the electrodes respectively contacting the two auricles and/or the heads in the vicinity thereof. In this case, the electrical connection between the two additional structures can be achieved by the spectacles structure, or the additional structure can be additionally connected by the connecting line, and the required circuit can be partially or completely disposed on the spectacles structure according to requirements. Or in an additional structure; in another aspect, the position of the additional structure is not limited to the back of the ear, for example, it may be disposed at the side of the front side of the ear, or at the same time in front of the ear and behind the ear, as long as it is not The user can be influenced without limitation. On the other hand, the additional structure can also be used only to set up the circuit to drive the electrodes on the glasses to perform signal extraction after being electrically connected to the glasses structure; further, the The additional structure can be implemented in a removable form to allow the user to selectively re-use when needed Additional structures are incorporated into the spectacles structure for measurement.

Yet another possible way is to combine the eyeglass structure with the earwear structure to provide electrodes and circuitry together. The advantage of using the ear-wearing structure is that the structure of the ear-wearing structure itself can be stably placed on the ear, which is quite convenient to use, and the distance from the structure of the eyeglass is close, and if the connecting line is used between the two, it is not obvious. In addition, the combination of the spectacles structure and the ear-wearing structure also broadens the range in which the electrodes can be placed, and also increases the types of signals that can be obtained. Therefore, it is a highly advantageous combination. In actual implementation, the ear-wearing structure may refer to embodiments of the above additional structure, for example, may be disposed on one side or both sides, may or may not have electrodes on the surface, and/or may be implemented as removable or non-removable. Forms, etc., can have various possibilities, no restrictions.

When the electrode structure is used to set the electrode, the connection between the electrode and the circuit can be achieved by using the existing conductive portion of the eyeglass structure, in addition to the manner in which the wire can be embedded in the eyeglass structure. Glasses made of materials, for example, metal glasses, can also utilize the original conductive parts in the eyeglass structure, for example, a metal pivoting shaft structure for joining the front frame and the temples on both sides, the original metal conductive parts in the frame, metal The nose pad, and/or the original metal conductive parts in the temples are all feasible. Moreover, even in this way, even the common eyeglass structure can be used to extract physiological signals, and the appearance is not obvious. Higher acceptance is a more advantageous option.

In addition, the electrodes implemented on the spectacles structure are also suitable for the contact securing structure as described above, for example, as a dispersion electrode, a bump electrode, and/or a telescopic electrode, in addition to being adapted to the back of the auricle and / / or the shape of the V-shaped depression, especially when there is a possibility of hair at the electrode contact position, the structural design of dispersion, protrusion, expansion and the like can help to pass through the hair, so that The difficulty in contact between the electrode and the skin is reduced. For example, FIG. 22f shows a case where a plurality of dispersed telescopic electrodes are provided on the temples. Further, by implementing the electrodes as a plurality of dispersed contact points, the range of the electrodes may be Therefore, it is expanded, which is advantageous for overcoming the size difference of different user heads, and is quite advantageous.

Here, it should be noted that although specific embodiments of the present invention have been described, it is to be understood that these are by way of example only and not limitation, as long as the electrodes are covered by the support of the ear and the ear cartilage skin is covered. The contact lens structure or the ear wear structure is within the scope of the present invention, and it is also possible to combine various embodiments at the same time without limitation.

In addition, since the present invention is intended to provide a way for a user to obtain an EEG signal through a wearable method at any time, it is preferably in the form of a dry electrode, for example, a conductive metal, a conductive rubber, a conductive silicone, a conductive foam, Conductive fibers, etc., to maximize ease of use.

The following is a description of the possible forms of electrode placement when actually detecting brain activity.

Please refer to Figures 16a-16b for a schematic view of the simultaneous placement of two electrodes on an in-ear housing. As described above, the upper part of the auricle and the lower part of the auricle can be used as the positions of the motion detecting electrode 200 and the reference electrode 202, respectively, and therefore, as long as the inner side of the auricle contacted by the inner ear casing is properly positioned, The arrangement of the two electrodes required to obtain the EEG signal can be completed in a single in-ear housing.

As mentioned above, the two EEG electrodes should be able to obtain EEG signals. In addition to the distance between the two electrodes, if there is sufficient independence between the two electrodes, it can also be a way to obtain effective EEG signals. The range of contact with an inner ear canal is small, but due to the physiological structure of the ear canal It becomes a spatial interval, so even at a very small distance, it is possible to obtain an EEG signal that is sufficient for analysis.

Therefore, in Figure 16a, the two electrodes are located at the upper part and the lower part of the inner ear shell to contact the upper ear wall and the lower tragus/tragus notch. The upper electrode is used for motion detection. The electrode, and the lower electrode serve as a reference electrode. In addition, in FIG. 16b, one electrode contacts the tragus as a reference electrode, and the other contacts the arm wall opposite to the position of the tragus as a motion detecting electrode; or, alternatively, The movable detecting electrode disposed on the contact surface between the inner ear shell and the bottom of the ear can also be used by using the contact otoscope, the inter-tragus notch, and/or the reference electrode of the tragus, for example, as shown in the sixth The inner ear housing is shown to obtain an EEG signal. When determining the position of the activity detecting electrode and the reference electrode, it is preferably distributed as much as possible on opposite sides of the ear canal in order to obtain an effective EEG signal.

Here, the in-ear housing can simply be provided with only electrodes, and is connected to a circuit that houses a circuit for acquiring signals, such as a processor, a battery, etc., and a wireless transmission module, and the setting position of the host is There is no limitation, for example, it can be placed behind the ear or worn on the body, for example, in the form of a neck (as shown in Figures 24a-24d), in the form of glasses, in the form of a headwear, in the form of a wrist, or in an arm. The wearing form or the like, or the inner casing of the ear can also be directly implemented to include the required circuit therein, so that it can be changed according to actual needs without limitation.

In addition, the in-the-ear housing can also be configured to provide only a single electrode to contact the ear wall, the tragus, the tragus, and/or the tragus. For example, the electrodes on the inner ear can detect brain activity in conjunction with electrodes disposed directly on the skull, for example, through a wearable structure such as a headband, a headgear, a patch, or the like. In the parietal lobe, prefrontal lobe, and / Or the position of the occipital lobe or the like, and preferably, the electrode on the inner casing of the ear is implemented as a reference electrode; and the electrode on the inner casing of the ear can also be implemented as a movable detecting electrode, and is disposed on the a reference electrode on the inside of the ear clip on the earlobe (as shown in Fig. 16c); of course, an electrode may be provided on each of the bilateral in-ear housings, for example, an electrode on an in-ear housing may be used as a reference electrode The configuration (ie, the lower part of the contact auricle) is matched with the configuration of the movable detection electrode on the upper electrode of the other in-ear housing (ie, the upper part of the contact auricle), however, it should be noted that there is enough between the two ears. The distance between the electrodes is not limited, so that the two ear inner casings are in contact with the upper part or the lower part of the auricle, and an EEG signal sufficient for analysis can be obtained. For example, one ear inner casing can be contacted. The skin of the upper part of the auricle, the other inner ear casing contacting the skin of the lower part of the auricle, or the two inner ear shells respectively contacting the upper part of the skin of the auricle; or alternatively, the electrode may be implemented To contact the bottom of the ear (as in section 6b) As shown, for example, the electrode on one of the inner ear shells contacts the ear wall, the tragus, the tragus between the tragus, and/or the tragus, and the electrode on the other side of the ear contacts the bottom of the ear, or The electrodes on both inner ear shells are in contact with the bottom of the ear, so there are various possibilities and no limitations.

Next, when implemented in the form of an earhook, the electrodes on the extension member can be selectively contacted with a V-shaped depression, an upper portion of the back of the auricle, and/or a lower portion of the auricle. As shown in Fig. 17, the two electrodes are disposed on the extension member, a skin contacting the auricle and the V-shaped depression between the skull and/or the upper portion of the auricle, as the motion detecting electrode 200, and the other is Touching the skin on the lower part of the back of the auricle as the reference electrode 202; or the electrode on the extension member can detect the brain activity with the electrode directly disposed on the skull, for example, through a headband, a helmet (headgear) ), a patch, etc., are placed on the parietal leaf, a position such as a prefrontal lobe, and/or a occipital lobe, and preferably, the electrode on the extension member is implemented as a reference electrode; or, alternatively, the electrode on the extension member can also be used in conjunction with the ear clip to be placed on the earlobe The electroencephalogram signal is obtained by the upper reference electrode; in addition, one electrode may be disposed on each of the bilaterally extending members, for example, one side may be implemented as a reference electrode (ie, the back side of the contact auricle is lower), and the other side is used as a motion detecting electrode ( That is, contact with the V-shaped depression and/or the upper part of the back of the auricle), however, since there is a sufficient distance between the two ears, the position of the electrode is not limited, so whether the two-side extension member contacts the upper part of the auricle or In the lower part, EEG signals sufficient for analysis can be obtained without limitation.

Further, Figures 18a-18d show other possible embodiments according to the present invention, wherein Figure 18a illustrates the tragus or tragus between the in-ear housing contacting the lower inner surface of the auricle, and the extension member contact An example of a V-shaped depression and/or an upper part of the back of the auricle, in which case the electrode on the extension member can be applied to contact the skin of the skull in addition to the skin of the V-shaped depression and/or the back of the auricle, without limitation. In addition, Fig. 18b exemplifies an example in which the inner ear shell contacts the upper part of the inner surface of the auricle, and the extension member contacts the lower part of the back of the auricle. Further, it can also be implemented as an electrode on the inner part of the ear. Contacting the bottom of the ear (as in the case of the ear can shown in Figure 6b), and the electrodes on the extension member contact the V-shaped depression or the skin of the skull, or the skin on the back of the auricle; or, alternatively, The method is implemented to extend the ear clip from the extension member and place the electrode on the earlobe to obtain an electroencephalogram signal by contacting the inner surface of the auricle with the inner ear shell contacting the upper upper ear wall and/or the bottom of the ear. Here, it should be noted that the electrodes on the inner and back sides of the auricle are preferably still distributed on opposite sides of the ear canal to ensure the spatial separation required to obtain the signal.

In another preferred embodiment, as shown in Fig. 18c, the length of the extension member can be shortened, And by providing an adjustment mechanism, the extension member can be moved up and down, so that not only the electrode contact can be more stable, but also can adapt to different user's auricle size. In this example, the electrode on the inner ear housing Implemented as the reference electrode 202 to contact the position of the tragus and/or tragus notch, and the electrode contacting the V-shaped recess and/or the back of the auricle is implemented as a motion detecting electrode 200 that can contact the V-shaped recess and/or Or the skin on the back of the auricle or the skin of the skull, without limitation; in a further preferred embodiment, as shown in Fig. 18d, the extension member is embodied to be positioned below the in-ear housing such that the electrode thereon The lower part of the auricle is contacted, for example, the back of the auricle above the earlobe, and the effect of moving from bottom to top can also be achieved by providing an adjustment mechanism to increase the contact stability to accommodate different auricle sizes.

Alternatively, it may be implemented as shown in Fig. 19a, in which the portion of the ear front member 60 that does not enter the ear canal is implemented to have a smooth curvature, for example, a cylinder, and the extension member 62 is also implemented to have smoothness. The curvature of the electrodes 202, 200 are respectively disposed on the surface of the portion that does not enter the ear canal, and the extension member faces the surface of the V-shaped depression/auricle back skin, in which case as long as the electrode is distributed in a sufficient range It can be easily rotated by rotating the entire ear-wearing structure, for example, centering on a cylinder, and adapting to different auricle sizes of different users. For example, Figure 19b shows that it is placed on a larger auricle. The case of Fig. 19c is set on a smaller-sized auricle. As can be seen from the figure, since the electrodes 200, 202 are distributed over a range sufficient to cover the displacement caused by the rotation, such a design can be adapted. Different auricle sizes ensure contact between the electrodes and the skin, and of course, for the sake of simplicity, the entire outer surface of the cylinder, and/or the extension The entire surface of the extending member facing the V-shaped recess is implemented as an electrode, for example, all of which are made of a conductive material, so that various types can be used. There are no restrictions on possible choices.

Furthermore, further, in this example, as long as the entrance ear canal portion and the non-incision ear canal portion are formed to have an angle, the unincorporated ear can be naturally transmitted through the action of placing the ear canal. The track portion is firmly maintained on the inner surface of the auricle, and the force applied toward the tragus can be simultaneously achieved, which further contributes to the contact stability of the electrode. In addition, different sizes can be provided for different users. Access to the ear canal portion also helps to maintain the portion that is not in the ear canal stably maintained inside the auricle.

On the other hand, the electrode that does not enter the ear canal portion can also be implemented to contact the position of the tragus. For example, the angle of the in-ear canal can be adjusted to face the tragus by adjusting the angle of the inner ear canal. Direction, in this case, as long as the portion entering the ear canal is formed of a resilient material, no pressure is applied to the ear canal, and the portion that does not enter the ear canal is naturally inserted into the ear. The space between the screen and the ear canal is formed in a relatively stable manner; further, if the stability of the contact between the electrode and the tragus is increased, the contact between the electrode and the tragus can be further ensured by adding a protrusion. For example, as shown in Fig. 19d, the protrusions 206 for arranging the electrodes may be formed of an elastic material, and thus, there is no limitation.

In still another aspect, the extension member can also be implemented to provide a force having a skin facing the back of the V-shaped recess/auricle to ensure contact between the electrode and the skin thereon, for example, by using an elastic material. For example, an elastic metal, an elastic rubber or the like, as shown in Fig. 19e, the extension member is embodied to have a restoring force, and can be restored to the original shape after being pulled open on the auricle, thereby being closely attached to The back of the auricle and the effect of stabilizing the contact between the electrode and the skin.

And when the extension member described above only provides the electrode function, that is, most of the circuits Further, when all are disposed in the in-ear housing, the extension member can also be implemented in a form removable from the inner housing of the ear, for example, by providing a connection port, so that the convenience can be achieved. Benefits of storage and carrying. In actual implementation, for example, the extension member can be implemented by an elastic conductive material and can be directly used as an electrode, for example, elastic steel, memory metal, conductive rubber, conductive silicone, etc., or the extension member is also It can be implemented to complete the electrical connection between the electrodes on its surface and the circuitry within the in-the-ear housing when connected to the inner housing of the ear, with various possibilities.

Still further, with such a removable form, the present invention will provide another implementation option, i.e., the electrode on the extension member can be used as an extension of the electrode on the inner housing of the ear, for example, when the ear When there are two electrodes on the inner casing, one of the electrodes can be replaced by the external extension member, and can be selected as another electrode contact, for example, from the contact inside the auricle to the contact V-shaped depression/ The back of the auricle, on the other hand, also provides another means of attachment, for example, to increase the relative force between the extension member and the inner housing of the ear; or, alternatively, the extension member can simply be used as an extension fixing structure to further increase The fixing force between the inner ear shell and the auricle. Therefore, there are different setting options depending on the needs, and there is no limit.

In still another preferred embodiment, as shown in Fig. 20, the inner casing of the ear is not provided with an electrode, but is used for fixing, and simultaneously provides a magnetic force to attract the electrode contacting the lower half of the back surface of the auricle. The other electrode is carried by an extension member extending from the inner ear housing to contact the V-shaped recess and/or the upper back skin of the auricle, in particular, the extension member and the inner ear housing The adjustment mechanism can be implemented to adapt to different ear sizes, and the electrode under the contact auricle can be connected with the extension member by using a connecting wire 64 or a soft material, so that even if the extension member appears due to the adjustment mechanism The displacement will not affect the contact position of the lower electrode, so In addition, not only the contact stability of the two electrodes can be ensured, but also the effect of adapting to different auricle sizes is achieved, which is quite advantageous; alternatively, it is also advantageous that the extension member extending from the inner casing of the ear is also advantageous. It can be implemented to be curved according to the shape of the auricle, for example, directly as a connecting wire, or made of an elastic material, etc., so that when the electrode contacting the back of the auricle is used, the electrode is used between the ear and the inner casing of the ear. When the magnetic attraction is fixed, the electrode contacting the V-shaped depression and/or the upper part of the back of the auricle may be placed just between the auricle and the skull, and may be caused by the pulling force generated by the magnetic attraction. The contact is more stable, and further, the extension member can also be implemented as replaceable, for example, with different lengths or different materials to accommodate different users.

Here, it should be noted that the material and shape of the extension member may vary depending on the implementation, regardless of the circumstances, for example, the extension member may be made of a resilient material having a restoring force. For example, elastic metal, elastic plastic, silicone, etc., to ensure that the electrode always has a contact force toward the back of the auricle; or the extension member can be made of a plastic material to allow the user to shape according to the shape of the auricle Bending, for example, memory metal, flexible plastic material, etc., also ensures contact stability of the electrodes, and therefore, there are various possibilities and are not limited.

In addition, the circuit required to obtain the signal (such as 40 in FIG. 24d), such as a processor, a battery, etc., and a wireless transmission module (such as FIG. 26, 42) may be disposed in the ear front component. Or placed in a housing behind the ear, or placed in a host connected through a connecting line to be worn on the body, for example, in the form of a wrist wear, a neck wear, a head wear, a glasses, or The form of the arm wear, etc., can also be changed according to actual needs, without limitation.

In a preferred embodiment, in particular, whether it is simply placed in the ear In the form of an extended component, the main body can be further configured to simultaneously accommodate a wearable structure 30 disposed on the neck and the head, as shown in Figures 24a-24d, that is, the wearable structure can be When it is selectively placed on the neck or the head according to the needs of use, and is worn on the head, the wearable structure can be arranged in front of the forehead (Fig. 24c), on the top of the head, or on the head. There is no limit to the rear of the department.

Here, the wearing structure is implemented to have two end portions, and a curved portion connecting the two end portions, that is, a shape similar to C, and the wearing structure can be adapted to be disposed on the neck or the head through the curved portion. Preferably, the curved portion at least partially conforms to the curve behind the neck such that the wear portion falls on both sides and/or the front of the neck when the neck is wrapped around the neck. Forming a stable setting; on the other hand, when placed on the head, the curved portion can conform to the curve in front of, above and/or behind the head, and the two ends will fall on both sides of the head. To achieve a stable combination with the head.

First of all, when implemented in a neck-wearing form, since the neck is used as a support, the volume and shape of the main body can be freely changed, and compared with the ear-wearing form or the wrist-worn form, except for wearing with the ear. The length of the connecting line between the structures 32 and 34 is shortened, and the movement of the hand is not affected by the wiring, which increases the convenience of use, and is also set in the inner casing of the ear or the setting of the main body. In the way of the back of the ear, in addition to reducing the burden on the ear, such a method can also increase the stability of the setting by reducing the volume of the inner casing of the ear, and such a neck wearing form is the same as a general wearing necklace. The user is quite easy to adapt.

Furthermore, when implemented as a head-wearing form, since the contact with the head is increased, the possibility of obtaining more EEG signals of the cortex of different brain parts is also increased, and therefore, The user can determine and obtain the EEG signal by selecting different wearing positions. For example, referring to FIG. 1, when the electrode is set at the forehead position, the frontal area A brain signal can be obtained when set in the head. In the upper part, the brain signal of the parietal zone B can be obtained. When the head is located behind the head, the C-brain signal of the occipital region can be obtained, and when the electrodes are disposed on the two ends, the D-brain signal of the temporal lobe can be obtained. When the electrode is placed on a portion that will contact the periphery of the eye, for example, a position such as a forehead or a temple, an EOG signal can be simultaneously obtained.

In addition, the electrode contacting the head may also be implemented to obtain an electroencephalogram signal together with the electrode on the ear-wearing structure, without limitation, and when the contact position of the electrode on the wearing structure has hair, for example, the head and the head The position of the rear side, the side of the head, and the like may be as described above, using a contact securing structure, for example, as a dispersion electrode, a bump electrode, and/or a telescopic electrode, to help pass through the hair. The difficulty in contacting the electrode with the skin is lowered.

Here, the wearing structure can be adapted to be worn on the neck and the head at the same time, and there are different implementation possibilities. For example, the material can be applied to the sides of the head by selecting a material, for example, an elastic material. Achieving a fixed effect, such as elastic steel, elastic plastic, etc.; also through structural design, for example, can be just fit to be placed on the auricle, or can have a structure to prevent movement; and/or can also be added by adding auxiliary members Achieving stable contact with the head, for example, by adding a structure that tensions the two ends, such as an elastic band, or by adding a cushioning structure to the inner surface of the wearing structure, the wearable structure can be stably maintained on the head. Therefore, there is no limit. Further, if the circuit is mainly distributed at the two ends, the curved portion can be replaced to replace different shapes, materials, sizes, colors, etc., so that the use is more convenient, on the other hand, relative Ground can also be implemented as a replacement of the two ends, which can be changed by replacing different circuits. The function of the line, therefore, can have a variety of possibilities, no restrictions.

In addition, through such a structural design, since the feeling of wearing a necklace is the same, the user will not feel an extra burden, and on the other hand, the accommodation space of the circuit can be increased to increase the available space. Features such as configurable high-capacity batteries for extended usage, music playback, GPS positioning, and/or additional control interface for easy access to both ends as shown in Figure 24a Etc., are all quite advantageous choices.

In addition, when implemented in a wrist-worn form, it is particularly advantageous that since the wrist-worn device, for example, a wristband, a watch, is one of the most commonly used portable information providing interfaces for general users, The wrist-worn structure 52, together with the additional information providing interface, will allow the user to conveniently obtain information when needed, just like watching a watch, so the situation will be as shown in Figure 25a. The watch/brace with the EEG signal capture function is usually worn on the wrist. When it is necessary to measure the EEG signal, it is only necessary to connect the EEG electrode and set it on the ear to form a wrist that can be used anywhere. The wearing type EEG detecting device, wherein the connected electrode may be in any of the ear-wearing forms described above, for example, a single ear-wearing structure having two electrodes, or two ear-wearing structures respectively The form of the electrode can be determined according to actual needs. If a single ear-wearing structure including two EEG electrodes is used, only one connecting line will be needed, in addition to the significant improvement in ease of use. Also significantly reduced the degree heteroaryl, Also, when using two ear worn structure may further embodiment can be obtained in the form of dual channel (two channels) of EEG signals, left and right brain in the case of monitoring activities. Therefore, no matter how it is implemented, it is quite advantageous.

When implemented in the form of glasses, there are also a variety of electrode configuration options, for example. For example, as shown in FIG. 22a, the motion detecting electrode 200 can be disposed at a position on the temple that contacts the V-shaped recess and/or the skin on the back of the auricle (above the auricle), and sets the reference electrode 202. At a position where the end of the temple is bent to contact the skin below the back of the auricle (the auricle is below), further, the bent portion of the end of the temple may be implemented to have elasticity to increase the stability of the electrode contact; or As shown in Fig. 22b, the electrode may be placed in contact with the skin on the back of the auricle by contacting the V-shaped recess and/or the upper portion of the skin on the back of the auricle with the additional structure 204 coupled to the same temple. Here, the additional structure may contact any part of the skin on the back side of the auricle, and may also be implemented on the temple on the other side without limitation; or, as shown in Fig. 22c, may extend to the rear of the skull. The end of the temple is provided with an electrode contacting the occipital region, and then the same temple or another temple is used to contact the V-shaped depression and/or the upper part of the back of the auricle, and such a configuration is particularly suitable for setting The spectacles structure without the pivot axis and the original temples extending rearward as shown in Fig. 23d; or, as shown in Fig. 22d, the V-shaped recess and/or the auricle is contacted by the additional structure 204 on the temples. The skin on the upper part of the back and the skin on the lower part of the back of the auricle; or, the two electrodes are respectively placed on the two side glasses to contact the V-shaped depression on both sides and/or the upper part of the back of the auricle, or The change may be made by bending the end of the temple to the lower side of the auricle (as shown in Figure 22a), or because there is sufficient distance between the two ears, or both sides may be bent at the end of the auricle, or It is equally feasible, without limitation, to use the unilateral or bilateral arrangement of additional structures to contact the back of the auricle (as shown in Figure 22b); or, as shown in Figure 22e, by placing the electrodes on the bridge of the nose/mountain Brain activity detection is performed in the area between the two eyes, and on the skin of the V-shaped depression and/or the upper part of the back of the auricle or the skin of the lower part of the auricle. Therefore, there are various options, no restrictions, as long as they are through glasses. The position and arrangement of the frame of the structure in contact with the skull and/or the auricle are within the scope of the present invention, and the position and form of the electrodes are only intended to be exemplified and may be substituted and/or combined with each other. limit.

In particular, when the electrode is disposed close to the periphery of the eye, for example, as shown in Fig. 22e, when placed in the bridge of the nose/mountain/eye, the temple, an electro-oculogram (EOG) can also be obtained, wherein the eye The electrogram measures the corneo-retinal standing potential present in the anterior and posterior eyes of the eye and can be used to determine the position of the eyeball and the physiological changes in eye movement. Here, since the frequency and amplitude of the EO and EEG signals are different, the signal processing can be separated from each other. Therefore, in the concept of this creation, at least two electrodes can be used to obtain the two. Signals, for example, simply place one of the electrodes in the area between the bridge of the nose/mountain/eyes, or in the position of the temple, and then place the other electrode on the inside, back, and/or the auricle. The position of the V-shaped recess can simultaneously acquire the EEG signal and the EEG signal without any special settings. Moreover, such a method is particularly suitable for implementation on the structure of the glasses, and the user can wear the glasses without extra steps. It is quite convenient to measure two kinds of signals.

In addition, in a special embodiment, a plurality of electrodes may be disposed on both sides of the glasses to respectively obtain signals of the left and right brains, for example, two electrodes are arranged on the right side of the temple and/or Or on the frame, and the other two electrodes are distributed on the left side of the temple and/or the frame, so that as long as the circuit is separated, the two-channel EEG acquisition device is formed, which is quite advantageous. In this case, the distribution of the circuit can be directly disposed in the glasses structure of the left and right parts, or the circuit can be set by the combination of the external module and the temple. The way of implementation.

Further, the two electrodes for obtaining the EEG signal can also be implemented to be disposed through the eyeglass structure and the ear wearing structure. For example, an ear structure can be extended from the eyeglass structure, or the eyeglass structure has a connection port. By electrically connecting an ear-wearing structure, through the structure of the glasses, the V-shaped recess, the back of the auricle, the temple, the bridge of the nose, and/or the area between the eyes and the eye can be selected, and the structure can be worn through the ear. Select contact V-shaped recess, the back of the auricle, the bottom of the ear, the wall of the ear, the tragus, the tragus between the tragus, and / or the tragus to jointly obtain the EEG signal. Here, the ear-wearing structure can be embodied in the form of an in-ear housing or in the form of an ear hook, without limitation.

In the present creation, the eyeglass structure, the earwear structure, and the electrodes can also have different configuration options. For example, in a preferred embodiment, as shown in FIG. 23a, one electrode is located on one temple of the eyeglass structure, and the other electrode is located on the earwear structure, and the circuit system is disposed on the earwear. In the structure, the electrode 721 located on the spectacles structure 72 is disposed at a position where the spectacles structure is worn on the head, and the position of the electrode is in contact with the head and/or the skin of the auricle through the fixing force itself, and the other electrode is provided. 702 is disposed on a surface of a bonding structure 701 in which the ear wearing structure 70 and the temple are combined to contact the skin of the skull and/or the auricle after the ear wearing structure is combined with the eyeglass structure, in this case, In order to connect the earwear structure, the eyeglass structure has an electrical contact region 722 on the side temple provided with the earwear structure, which is connected to the circuit system in the earwear structure and the electrode 702 on the surface of the bonding structure. The electrode 721 on the other side of the temple is connected to form a sampling loop; alternatively, the electrode 721 can also be disposed on the frame to form a sampling loop together with the electrode 702 on the ear-worn structure. Therefore, as per need There are no restrictions on changing settings.

In addition, the ear-wearing structure and the eyeglass structure can also be implemented in different combinations. For example, as shown in FIG. 23b, the temple end of the eyeglass structure is implemented as a connecting port 73 for interposing with the ear-wearing structure. In the embodiment, the mechanical connection and the electrical connection are achieved, and in this embodiment, the electrode 702 on the ear-wearing structure is disposed on the surface of the in-ear housing of the ear-wearing structure.

Furthermore, it is also possible to implement that both electrodes are disposed on the surface of the eyeglass structure, as shown in FIG. 23c, the electrodes on both sides have electrodes 721, 723, or two electrodes are respectively located on one side of the temple and the frame At this time, it is only necessary to connect the upper ear wearing structure, and the electrophysiological signal can be extracted through the circuit system housed in the ear wearing structure. Further, an electrode may be disposed on the ear-wearing structure, so that the electrode on the ear-worn structure can be regarded as a reference electrode, and the electrodes 721, 723 can be used as active detecting electrodes to obtain respectively or simultaneously. EEG signals on both sides of the temporal lobe.

Here, it should be noted that although the two electrodes are arranged in the form of the two mirrors on both sides of the temple, it is not limited thereto, and the two electrodes may be implemented to be distributed on one side of the temple and On the frame, and further, it can be implemented as more than two electrodes. For example, electrodes are provided on both the temples and the frame, so that various possibilities are possible. In addition, the combination of the earwear structure and the eyeglass structure is also There are many possibilities. In addition to the use of the connection port or the use of the sleeve, there are other options, such as magnetic attraction, mutual engagement, or chute combination. In addition, in addition to the conventional form of glasses as shown in the figures, the spectacles structure may also employ a non-pivoting shaft form spectacles structure as described above, for example, an elastic continuum without a pivot shaft as shown in Fig. 23d, and / or lens-free eyeglass structure 72, can be changed according to actual needs.

In another preferred embodiment, as shown in FIG. 23e, the earwear structure 70 is disposed on the eyeglass structure 72 through the additional structure 204, and in particular, the additional structure is configured to have a curvature and toward the rear of the head. The position of the occipital lobe, therefore, in this embodiment, the electrode 721 on the additional structure is implemented in a dispersed form to facilitate contact of the electrode through the hair to contact the scalp, and the other electrode 702 is disposed in the ear-wearing structure. The surface is in contact with the ear, whereby the electrode 702 disposed on the ear-worn structure is regarded as the reference electrode, and the electrode 721 on the additional structure is regarded as the motion detecting electrode to obtain the electroencephalogram signal of the occipital region. Here, the circuit can be disposed in the additional structure, and/or the ear-wearing structure, without limitation, and the additional structure can be implemented to be sleeved on the temple, or can be implemented to replace a part of the temple, nor limit.

Furthermore, there are different possible implementations for the electrical connection between the electrodes and the circuit system distributed on the spectacles structure. For example, the spectacles structure made of a conductive material can be directly used to achieve electrical connection, or can be implemented. It is a feasible way to provide a conductive portion in the eyeglass structure.

Here, since the spectacles structure can provide more selection of the position of contact with the head, for example, near the nose, behind the head, etc., when the ear-wearing structure and the spectacles structure can be used in combination with each other, 遂 makes it available. Physiological signals are more extensive and quite advantageous.

In addition, as shown in FIG. 25b, the circuit system can also be disposed in the wrist-worn structure 52, and similarly to the foregoing, the user can normally have a wrist-worn structure having an EEG function, for example, a watch. The wristband, etc., is worn on the wrist. When there is a need to measure the EEG signal, connect the EEG electrode in the form of glasses, or wear the wrist-worn structure and glasses at ordinary times, and connect the two when there is a measurement demand. In this way, it is also quite convenient and suitable for daily life. Choose. Here, the connected electrodes may be in the form of any of the aforementioned spectacles, without limitation.

In addition, in addition to the EEG electrodes disposed on the earwear structure and the spectacles structure, the brain activity sensor according to the present invention may also be implemented as having other EEG electrodes, for example, from an earwear structure or a spectacles structure. Extending the electrodes disposed at other positions on the head, for example, an EEG signal that is placed on the forehead to obtain the frontal lobe area, an EEG signal that is placed on the top of the head to obtain the parietal region, and/or a occipital lobe that is placed behind the skull. The brain signal of the area, etc., and more particularly, when implemented in the form of glasses, the electrode behind the skull can also be extended by means of the temple extending backward, and therefore, can be changed according to actual needs, without limitation; In addition, when the electrode is provided with hair, such as the top of the head, the back of the head, etc., it is optional to use a needle electrode, a dispersion electrode, or other electrode form capable of obtaining a signal through the hair, or a spring loaded electrode as described above. To increase ease of use.

It is to be noted that the preferred embodiments described above are by way of example only, and not limitation, the embodiments may be modified, and/or category.

Since the brain activity sensor according to the present invention uses the ear as a medium disposed on the human body, it is quite suitable to be implemented in a form combined with the earphone, especially when implemented in an ear wear form, for example, can be combined for listening. Music headphones, or earphone microphones for transmitting and receiving sounds, and are not limited to bilateral earwear or single-sided earwear, or in-ear casing or ear-hook form, are suitable for the concept of this creation, so In one case, it can be further integrated into the daily life of the user, for example, can be used during commuting, and the form of implementation can be selected according to the user's habit of using the earphone, which is quite convenient.

In addition, when implemented in the form of glasses, the function of the earphone and/or the microphone can be provided by providing a sounding element and/or a sounding element (for example, a microphone) on the eyeglass structure, or the eyepiece lens can also be utilized. The manner in which the earphones are extended, in particular, the sounding element and the earphone used may be in the form of bone conduction, for example, in the form of a bone conduction, for example, directly in contact with the skull. There is no limit to the bone conduction speaker or the bone conduction earphone from the temple.

The brain activity sensor according to the present invention can also be implemented to communicate with a portable electronic device, for example, by wired or wireless means such as a headphone jack or a Bluetooth, and an external electronic device such as a smart phone or a tablet computer. Communication, in the case of a sound-emitting element (air-conducting or bone-conducting) and a sound-receiving element, the ear-worn or eyeglass-type brain activity sensor according to the present invention can be used as a hands-free receiver, For talking, playing music from a portable electronic device, etc.; further, by providing a vibration module, a sounding element (air conduction or bone conduction type), a display element, and a light emitting element, etc., according to the present The created ear-mounted and/or eyeglass-type brain activity sensor can further implement an information providing interface as the portable electronic device, for example, for providing an incoming call reminder, a mobile phone message notification, etc., and more integrated with the user. In daily life, as for the provision of information, there are various restrictions, such as sound, vibration, illumination, and lens display.

Further, when implemented to have a headphone function, especially for listening to music, it is preferably in the form of a binaural wear, as shown in Figures 24a-24d, to provide a better hearing effect for the user, for example. In this case, the in-ear housing can be provided in both auricles, and the music can be provided through a wireless connection or a wired connection between the two, for example, divided into left and right channels, and the music is made The body sound effect, in addition, can also be implemented as a memory in the earphone to store music and provide a play function, so that even if you do not communicate with the portable electronic device, you can listen to the music, making it more convenient to use.

Accordingly, in a preferred embodiment, as shown in Fig. 26, the monaural wearing brain activity sensing device 36 according to the present invention is implemented to have a wireless transmission module 42, for example, a Bluetooth, to externally The portable electronic device communicates with the portable electronic device, for example, by transmitting the acquired physiological signal and information to the portable electronic device, and on the other hand, in addition to the physiological signal capturing function, a sounding component 44, and an electrical signal transmission port for receiving signals from the outside, such as audio signals, where the source of the audio signal has several different options, for example, from the connection to the electrical signal The other ear device 38 of the transmission device, for example, the audio signal stored in the other ear device; or the external portable device, and may be obtained by wired or wireless means, for example, The other earphone device may be connected to the portable electronic device to obtain an audio signal by using a connection line or wirelessly connected to the electrical signal transmission port, or alternatively, It is a possible choice to obtain an audio signal by the electrical signal transmission and wired connection to the portable electronic device.

As for the playback of the audio signal, it is performed by the audio control circuit 46 located in the other ear-worn device, wherein the audio is transmitted through the electrical signal transmission between the two ear-wearing devices 36, 38. The control circuit can drive the sounding element to perform audio playback. Further, when the sounding element 44 is also included in the other earwear device, a stereo effect can be achieved.

Since the physiological signal capturing circuit and the audio control circuit are separately disposed in the design of the two earwear devices 36, 38, it is advantageous that the connection between the two earwear devices can be implemented as The removable form, for example, when the user only needs to perform physiological signal detection, the other ear wearing device 38 can be removed, and when there is a need to listen to music, only another One ear wearing device (and connected to the portable electronic device) can be used conveniently, and the other ear wearing device 38 can also be used alone to provide a single ear music playing function, and further, if the other The ear-wearing device is also provided with a sound-receiving component, and the other ear-wearing device can also be used as the earphone microphone of the portable electronic device; in addition, the other-side ear-wearing device can also be implemented as an electrode There is also no restriction on the simultaneous acquisition of EEG signals by the two ear-wearing devices. In this case, the connection between the two ear-wearing structures can be used to transmit physiological signals in addition to the transmission of audio signals.

Therefore, through such a design, the two earwear devices can be used alone, in addition to being used in combination, and can be strained according to changes in the user's use requirements at different times, which is a rather advantageous combination.

It should be noted that, depending on the purpose of use and the design requirements, the transmission between the two ear-wear devices, including audio signal transmission and physiological signal transmission, may also have various combinations, for example, in a single ear. In the case of obtaining a physiological signal, the wired connection between the two devices can be used only for transmitting the audio signal, and when the physiological signal is acquired through the electrodes respectively disposed on the two devices, the physiological signal is required to be wired. Mode transmission, and in this case, the audio signal can be implemented to be transmitted by wire, or wirelessly, without limitation.

As for the operation interface for controlling the playing of audio and determining whether to make a wireless connection, it can be set at a position convenient for the user according to requirements, for example, a connecting line between the ear wearing device and the portable electronic device, two ears. Wear the connection line of the device, or as described above There is no restriction on the wearing structure of the neck or the head.

On the other hand, when implemented in a double-eared form, whether the two-side ear-wearing structure is implemented as a wired or wireless connection, for audio playback and physiological signal acquisition control, the following options may be selected, for example, as The circuit in the ear-wearing structure controls the physiological signal, and the circuit in the ear-wearing structure on the other side controls the playing of the sound, and can also be implemented as a circuit in the ear-wearing structure to simultaneously control the physiological signal capturing and sound playing, without limitation. Further, the arrangement of the electrodes may be implemented by arranging electrodes on the unilateral ear-wearing structure for physiological signal extraction, or alternatively, the electrodes on both sides of the ear-wearing structure may be provided with electrodes, for example, may be two sides The electrodes cooperate to obtain the EEG signal, or the two ear-wearing structures independently perform the brain-electric signal acquisition, or change according to the requirements, and there is no limitation.

In another aspect, referring to Figures 27a-27d, the brain activity sensing device according to the present invention can also be implemented to have a connection structure for functional expansion. As shown in Fig. 27a, a connection structure 80 is implemented as It protrudes downward from the inner casing of the ear, and FIG. 27b shows that the connecting structure 80 protrudes and extends to the back of the auricle, or can also be implemented in the form of FIG. 27c, which can be variously selected according to actual needs, without limitation. .

Such a connection structure further increases the possibility. For example, in a preferred embodiment, the connection structure is used to connect one of the electrodes 102 for acquiring an electroencephalogram signal. For example, FIG. 27b shows that the electrode 82 is directly connected to the connection structure 80 to contact the ear. The back side, and the 27th figure, show that the electrode 82 is disposed on an external member 84 to contact the V-shaped area. In this case, the EEG signal can be obtained only by cooperating with the other electrode 100 on the in-ear housing. Or alternatively, it may be implemented to connect an electrode to the connection structure through a connection line, and Set in other locations, for example, another ear, head, etc. As for the medium, there are many options, for example, another ear wearing structure, eyeglass structure, head structure, or electrode patch, all feasible, no The limitation, wherein when set to other positions on the head, is advantageously equal to increasing the sampling position at which the brain electrical signal is obtained, which is helpful for obtaining brain electrical signals of different parts of the cerebral cortex.

That is, the connection structure provides the possibility of extending the electrode out of the inner casing of the ear and, further, can also be achieved by a carrier, wherein the carrier can be, as described above, the external member 84, There is no restriction on the other ear wearing structure, the eyeglass structure, the head structure, or the electrode patch.

On the other hand, for example, in the case of having two electrodes on the inner casing of the ear, the connecting structure can also be implemented to pass through the external form when the electrodes on the inner casing cannot reach stable contact. The contact is improved, that is, the external electrode 82 is replaced by the electrode on the inner casing of the ear. Therefore, various embodiments described above, for example, direct external electrodes, or electrodes carried through a carrier, are also suitable for use herein.

Further, the connection structure can also be used for other functional expansions, for example, for charging, and/or for connecting the sounding elements on the other ear-wearing structure with the sounding element 44 to achieve stereo effect, There may be various possibilities; in addition, as described above, the position and the protruding direction of the connecting structure may be changed according to requirements, for example, facing downward, extending to the back of the ear, or facing the direction of the face, etc., without limitation.

Furthermore, according to the brain activity sensor of the present invention, in addition to detecting the EEG signal, other physiological sensing elements or electrodes may be included to obtain other physiological signals.

For example, there may be at least one pair of light emitting elements and light receiving elements, in Therefore, the light-emitting element and the light-receiving element refer to a sensing element that acquires an optical signal by using a principle of PPG (photoplethysmography), for example, a person who performs measurement by means of penetration or reflection to obtain blood physiological information of the user, and thus Further analysis can obtain other physiological information, for example, information on changes in blood oxygen concentration can be obtained, and the user's heart rate sequence can be obtained by obtaining continuous pulse changes for correlation analysis. Therefore, the application range is quite wide and unrestricted. .

Here, when implemented in an ear-wearing form, the light-emitting element and the light-receiving element may be located on a surface that will come into contact with the skin of the ear or the skull, for example, an earlobe, an ear canal, an ear canal, an otoscope, and an incision between the tragus, There is no restriction on the tragus, the ear arm wall, the bottom of the ear, the back of the auricle, the V-shaped depression, or the skull skin in the vicinity of the junction between the auricle and the skull, as long as it is accessible through the ear-wearing structure. The inner and outer sides, the position near the auricle are all available, and one of the advantages is that when it is implemented to contact the ear canal or the ear armor/ear boat bottom, it is particularly suitable for fitting the inner ear shell together with the electrode in the ear. The surface of the inner casing, which is also suitable for implementation on the inner casing of the ear, is such that the light-emitting element and the light-receiving element are implemented to contact the tragus and/or the tragus between the tragus, for example, FIG. It is shown that the light-emitting element 210 and the light-receiving element 212 are disposed together with the electrode 100 on the surface of the in-the-ear housing that does not enter the surface of the ear canal portion, and therefore, as long as the portion entering the ear canal is set and aligned with the tragus Bit Naturally, blood physiological information can be obtained from the position of the otoscope. In these cases, the inner casing of the ear further provides a light-shielding effect, which is more favorable for obtaining high-quality signals, and a wearing action can be completed. The arrangement of the electrodes and the light-emitting elements as well as the light-receiving elements is a relatively convenient choice.

In addition, when implemented in the form of glasses, the light-emitting element and the light-receiving element may be located at any position where the lens structure is in contact with the skull and the ear, for example, the bridge of the nose, the area between the eyes, The temple, the auricle, the area near the auricle, and the like are also not limited. For example, the light-emitting element and the light-receiving element may be placed on the temple together with the electrode to contact the V-shaped recess, the upper portion of the back of the auricle, and / or the head near the auricle, for example, the temple, or even the form of the electrode surrounding the light sensor, which will simplify the contact position and reduce the complexity of use.

Furthermore, when implemented in the form of Figures 24a-24c, the light-emitting element and the light-receiving element may be disposed on the surface facing the interior when the wearing structure is worn on the head to obtain blood from the head. The physiological signal, for example, in addition to the blood oxygen concentration and the heart rate sequence, can also obtain the blood flow of the brain to represent the activity state of the brain, or can be set to be worn when worn on the head or the neck. The position close to the part, for example, on the exposed surface, and the blood physiological signal from the hand, there is no limit. And without limitation, the light-emitting element and the light-receiving element may also be disposed on the surface of the ear-wearing structure or the spectacles structure to allow the user's hand to approach the position to obtain blood physiological signals from the hand.

Further, an electrocardiographic electrode may be further included to obtain an electrocardiographic signal, for example, at least a first electrocardiographic electrode and a second electrocardiographic electrode, wherein the first electrocardiographic electrode may be implemented in a position according to the present invention. When the brain activity sensor is worn on the user, it will contact the user's auricle or the skin of the skull, for example, when implemented in the form of an ear, the extension member contacts the V-shaped depression, the back of the auricle or the skull The position of the inner ear shell in contact with the inner surface of the auricle, or when implemented in the form of glasses, the contact of the temple with the V-shaped depression, the temple, the back of the auricle, the position of the skull near the auricle, and the contact of the nose pad The bridge of the nose, the root of the mountain, and the area of the two eyes.

As for the second electrocardiographic electrode, there are various implementation options, for example, can be set in the ear. Wearing an exposed surface of the structure or the spectacles structure (or additional structure) for the user to touch through the touch of the hand, that is, the user can immediately obtain the heart by raising the hand touch when the measurement is needed The electric signal is quite convenient. Here, the exposed electrode can be made of metal, conductive rubber, or any conductive material, without limitation, and further, can be implemented as a non-contact type electrode, for example, a capacitive electrode, an inductive electrode. , or electromagnetic electrodes, etc., to increase the ease of use; in addition, the electrodes can also be extended through the connecting line to be placed at other locations, such as the neck, shoulders, chest, upper arms, wrists, fingers, etc., here In particular, the arrangement of the second electrocardiographic electrode can be further achieved through the wearing structure, for example, a neck-worn structure, a shoulder-worn structure, an arm-worn structure, a wrist-worn structure, a finger-worn structure, etc., or implemented as a patch. Forms, etc., all contribute to the fixation of the electrodes, and the advantage of this method is that since both electrodes are fixed to the wearer, continuous ECG signals can be obtained, as long as they match The memory can record the heart activity of the user for a long time, which is quite helpful for the diagnosis of the doctor. Here, it should be noted that even if the electrocardiographic electrode is disposed through the wearing structure, it can be implemented as The ECG signal acquisition is required, and there is no restriction. The user can select the usage mode according to actual needs.

Wherein, when implemented in the form of FIG. 24a-24c, the first electrocardiographic electrode can also be disposed on the earwear structure, and the second electrocardiographic electrode can be disposed on the wearable structure at the position accessible by the hand. Here, it can be implemented to be contacted by the hand when worn on the neck, or can be implemented by the hand when worn on the head, and the ECG signal can be obtained, and the connection line can also be obtained through the connection line. Extending out, there is no limit.

In addition, it should be noted that both ears are optional to set the position of the electrocardiographic electrode. However, after the experiment, it is known that the contact position of the exposed electrode or the extended electrode is The quality of the number has a considerable influence. When the left upper limb touches the exposed electrode or the extension electrode is placed on the left upper limb, the quality of the obtained ECG signal is much better than the signal obtained by contacting the right upper limb, especially the electrode. The left ear and the left upper limb have the best signal quality respectively. Therefore, when the ECG measurement is performed in contact with the ear, it is preferable to use the left upper limb to contact the exposed electrode or the extension electrode to avoid contact with the right upper limb. The signal quality is poor, which leads to misjudgment in the analysis.

Furthermore, the first electrocardiographic electrode in contact with the auricle or the skull skin can also be implemented to be shared with the electroencephalogram electrode, that is, one of the electrodes on the ear-wearing structure and the spectacles structure can be simultaneously used as the electroencephalogram electrode and The electrocardiographic electrode can increase the convenience of use in addition to the manufacturing cost and complexity, and the convenience of use can be increased by reducing the position to be contacted; in addition, the second electrocardiographic electrode can be further implemented as a common The form, for example, may be formed by extending the electroencephalic electrode to the exposed surface, or may be formed directly by the electroencephalic electrode on the inner side and the outer side, without limitation, due to the electrocardiographic signal (about a millivolt (mV)) The range and the amplitude of the EEG signal (approximately several to several tens of microvolts (μV)) are significantly different, and even if they are shared, the judgment of the signal is not affected.

Of course, it can also be implemented to have both a light emitting element and a light receiving element and an electrocardiographic electrode. In this case, the time required for the pulse wave to pass from the heart to the sensing position of the light emitting element and the light receiving element can also be obtained. It is the so-called Pulse Transit Time (PTT), and since PTT is related to the arterial blood vessel hardness that affects blood pressure, the reference blood pressure value can be calculated through a specific relationship between PTT and blood pressure values.

Moreover, when the hand touches the second electrocardiographic electrode on the exposed surface, the heart is obtained. When the electric signal is obtained, and then the PTT is obtained, since the hand needs to lift the contact exposed electrode, in this case, the detection position of the light emitting element and the light receiving element is the inner surface or the back side of the auricle, and the skull skin near the auricle. The bridge of the nose/mountain/two eyes or the hand touching the exposed electrode has a constant height relative to the heart. According to hemodynamics, PTT is affected by the height difference between the measured position and the heart position. Therefore, in this way, the common PPT measurement is usually due to the influence of the sampling position relative to the unfixed heart, so that it can be accurately obtained after calibration. The blood pressure value, and, such a measurement method is also not affected by standing or sitting posture, and is quite advantageous.

Next, the application range of the detecting device using the brain activity sensor according to the present invention will be described.

One of the applications is for neurophysiological feedback. For example, when performing a neurophysiological feedback program targeting relaxation, one of the options is to observe the proportion of alpha waves in the whole brain wave. In brain waves, In the case of α waves (about 8-12 Hz), the human body is in a relaxed state of waking state, so the degree of relaxation can be known by observing the proportion of alpha waves; or, when aiming at increasing concentration, Select to observe the ratio of theta wave (about 4-7Hz) to the beta wave (about 12-28Hz). In the brain wave, when the beta wave is dominant, the human body is in a state of waking and nervous, and when the alpha wave is dominant, it means the human body. It is in a state of relaxation and interruption of consciousness. Therefore, the purpose of improving concentration can be achieved by increasing the ratio of β wave to theta wave, for example, treating patients with ADHD (Attention deficit hyperactivity disorder). One method is to observe the ratio of the θ wave/β wave through neurophysiological feedback; in addition to observing the ratio of the θ wave to the β wave, the slow cortical potential (SCP) is also focused. The raw nerve The brain activity often observed in feedback, where the negative shift of the SCP is related to the more concentrated attention, and the positive shift of the SCP is related to the reduced attention, of course. It can also detect brain waves in other frequency ranges. For example, the appearance of gamma waves (about 28-40Hz) represents a highly focused state. In addition, there are other kinds of applications, for example, for monitoring epilepsy. Occurs as a basis for diagnosis/diagnosis, therefore, there is no limit.

In addition, since the degree of relaxation of the human body can also be judged by the condition of autonomic nervous activity, for example, when the parasympathetic activity increases, and/or the ratio of parasympathetic activity to sympathetic activity increases, the degree of relaxation of the body is increased, and therefore, The device of the present invention has a light-emitting element and a light-receiving element and/or an electrocardiographic electrode, and the heart rate sequence obtained through the analysis can obtain the autonomic nerve activity through the HRV, so that the information and the related brain can be integrated. The information of the activity is used together to assess the relaxation of the user's body for neurophysiological feedback.

As for how to provide physiological information to the user in time during neurophysiological feedback to achieve the effect of neurophysiological feedback, there is no limitation. For example, if implemented in the form of headphones, information can be directly provided by sound, for example, When the state of the brain wave shows tension, the use of rapid music indicates that the state of the brain wave shows relaxation when using a slow music expression; or, the state of concentration is expressed by powerful music, and the concentration of concentration is expressed by soft music; Alternatively, the user may be informed of the physiological state represented by the current brain wave state by the level of the sound frequency or by voice, or may also generate vibration through a portion in contact with the skin, for example, with a fast vibration frequency. Relaxation and tension represent slowness and tension; or, visual feedback can be provided through glasses. Therefore, visual, audible, and/or tactile sensations can be produced through the ear-wearing structure or the spectacles structure. There are various possibilities and no restrictions on the realization of the signal.

In addition, information can also be provided through an information generating interface connected to the detecting device, for example, a smart phone, a sounding device, a lighting device, etc., and there is no limitation.

Another application is to help with breathing exercises. Since RSA (Respiratory Sinus Arrhythmia) information can be obtained through the heart rate sequence, the synchronization between heart rate, respiration and EEG signals can also be observed as a basis for feedback. According to research, exhalation and inspiration cause fluctuations in blood flow in the blood vessels, and this fluctuation also reaches the brain with blood flow, which causes the brain waves to approach the low-frequency segment of the respiratory rate, for example, below 0.5 Hz. Fluctuation, therefore, in addition to knowing whether the synchronization between the two is achieved by resonance, the breathing pattern can be known by observing the brain wave, and the autonomic nerve is also caused by the sinus node and the vascular system of the heart. Systematic regulation, and the autonomic nervous system also feeds heart rate and blood pressure changes back to the brain through the baroreceptor system, which affects the function and function of the brain, for example, affecting the cerebral cortex, and can be measured by EEG. Yes, coupled with conscious control of breathing can affect the heart rate caused by the influence of autonomic nerves, therefore, there is a relationship between the three, so the good synchronization between the three can represent the body is more relaxed According to the state, the analysis result of the correlation synchronization can also be used as information for providing users with self-awareness adjustment for neurophysiological feedback.

In addition, since increasing the amplitude of the RSA helps trigger the Relaxation Response and relieves the accumulated pressure, the effect of increasing the proportion of parasympathetic/sympathetic nerve activity is achieved, so that the user's heart rate change pattern can be observed, and When the heart rate begins to accelerate, the guide informs the user that he can start inhaling, and when the heart rate begins to slow down, It is known that the user can start exhaling to achieve an effect of increasing the amplitude of the RSA, that is, causing coherence between breathing and heart rate, and also contributing to relaxation. Furthermore, due to the magnitude of the amplitude between the peaks and troughs of the RSA, that is, the difference between the maximum and minimum values of the heart rate during a breathing cycle, it is related to the activity of the autonomic nervous system. This information is provided to the user in real time as a basis for the user to adjust the physiological state.

Further, the breathing pattern of the user can be known by observing the fluctuation of the blood flow. For example, the light-emitting element and the light-receiving element provided at the position of the ear, the forehead, and the like can be used to obtain the pulse change, thereby obtaining the pulse change. Changes in blood flow.

Herein, the respiratory guidance/instantaneous physiological information may be provided by generating an audible, visual, and/or tactile sensing signal through the ear wearing structure or the spectacles structure, or providing an interface through the connected information, which may be according to actual needs. And change is not limited.

Here, the case where the wrist-worn EEG detecting device shown in Figs. 25a-25b is applied to physiological feedback and breathing training is particularly mentioned. Due to the portability provided by the wrist-worn device, the design of the EEG signal can be obtained only by the ear-wearing structure (unilateral or bilateral), so that the user can perform physiological feedback almost without time and place. Breathing training, at this time, if the electrode can be further disposed on the wrist-worn structure, the electrocardiogram signal is obtained together with the electrode on the ear-wearing structure, or the light-emitting element and the light-receiving element are disposed on the ear-worn structure or the wrist-worn structure. By obtaining the heart rate, the breathing situation can be understood, and the breathing training program can be performed, and if the electrocardiographic electrode and the light emitting element and the light receiving element are simultaneously provided, the pulse transit time (PTT) can be obtained and reused. The reference blood pressure value is calculated by the relationship between PTT and blood pressure, or PPT is further utilized as physiological feedback information. Therefore, you only need to wear a wrist-worn structure and an ear-wearing structure to get a variety of life. Information, and easy to operate, is a very advantageous implementation.

Further, in addition to the functions described above, the wrist-worn structure can provide other physiological signal detection options, for example, an electrode can be disposed on the surface in contact with the wrist, and the surface can be placed on the surface of the other upper limb. The electrode is configured to obtain an electrocardiogram signal by contacting the electrodes with two hands respectively; or, two electrodes may be disposed on a surface contacted by the wrist to obtain a skin electrical signal and/or a myoelectric signal; or, a finger wearing structure is extended The wearing structure can be implemented as having two electrodes on the surface in contact with the finger to obtain the skin electrical signal and/or the myoelectric signal, or having only one electrode and matching the other electrode for the other upper limb to contact. For example, it is disposed on the wrist-worn structure, the eyeglass structure, or the finger-wearing structure to obtain an electrocardiogram signal, wherein the finger-wearing structure can also be used to set the light-emitting element and the light-receiving element to obtain heart rate, blood oxygen concentration, and the like. Blood physiology information is also a fairly advantageous way.

Moreover, since the position of the wrist-worn structure is the position where the information providing interface is generally set, for example, a watch, a wristband, it is natural to provide physiological feedback through the wrist-worn structure during physiological feedback or breathing training. Information, and/or breathing guide, etc., or as a user's input interface, is quite convenient. Further, if the user chooses to close the eyes for physiological feedback or breathing training, the sounding element can also be disposed in the earwear structure. It is also a very advantageous way to give feedback and/or guidance to the user by means of the vibration of the wrist-worn structure and/or the ear-wearing structure.

Another type of application is for monitoring physiological conditions for use as a reminder, for example, to monitor alertness and drowsiness. As mentioned above, it is possible to know the state of the human brain by observing the frequency change of the brain waves, so it can be based on this. And the related reminder program is executed. In addition, when the ear wearing form is used, the eye can be measured when the electrode is placed in front of the ear or near the temple, or when the electrode is placed on the nose pad. The electric signal (EOG), through the eye-ray signal, can obtain information such as the number of times the user blinks and the speed, and can also analyze the degree of waking, drowsiness, or fatigue of the user, plus the brain activity of the creation. The sensor is in the form of earwear and glasses, which is suitable for carrying with you. Especially when driving, you only need to make sound through the earphones, or the part that comes into contact with the skin can make vibration or stimulation, or the glasses emit flash, or use the phase. The connected sounding device generates a reminder sound, which can achieve the effect of improving alertness and preventing falling asleep, and effectively reducing the probability of traffic accidents, which is quite practical and important.

Furthermore, the device according to the present invention can also be applied to the acquisition of sleep related information. As is well known to those of ordinary skill in the art, electroencephalograms are the primary basis for determining sleep staging. Generally, conventional measurement methods are, for example, placing a plurality of electrodes on the scalp and connecting them through a connecting wire. One machine, but since it must be measured during sleep, this method is not convenient for the user. Therefore, if the electrode configuration can be completed through the ear-wearing form or the glasses form, it is naturally a no-burden option, and In contrast, the unburdened detection method has less impact on sleep and will result in a test result that is closer to the daily sleep situation.

Furthermore, other electrophysiological signals can be measured by adding other electrodes or by sharing the electrodes, for example, EOG, myoelectric signal (EMG), ECG (ECG). , electrodermal activity (EDA), etc., and these electrophysiological signals are items included in multiple sleep physiological examinations (PSG, Polysomnography). For example, the electro-oculogram can provide REM (Rapid Eye Movement). Information, myoelectric signal Information such as sleep onset and sleep offset, molars and REM can be provided. ECG signals can be used to assist in observing the physiological state during sleep, for example, the state of autonomic nerves, the condition of cardiac activity, etc. Information about the sleep stage can be provided, and further, if a light-emitting element and a light-receiving element are added, blood oxygen concentration can be obtained to determine the occurrence of hypopnea, and/or additional action sensing elements can be added. For example, an Accelerometer, a G sensor, a gyroscope, a magnetic sensor, etc., can provide information on body movement, and/or a microphone can be detected. The situation of snoring, etc. Therefore, it is quite convenient to obtain a lot of information about sleep in the most unburdened situation by simply arranging the sensor on the ear.

Yet another application is for evoked potentials. Firstly, according to the setting position of the detection electrode of the creative activity, the measured brain electrical signal of the cerebral cortex and temporal region adjacent to the auricle is particularly suitable for detecting the function of the cerebral cortex in the temporal lobe region, and the cerebral cortex is detected. The leaf area is the center of the processing of auditory information, and has important relations with functions such as language and memory. Therefore, through the evoked potential test, for example, it can be used to understand the response of the subject to sound stimulation, for example, the reaction speed. , the degree of response (the amplitude of the brain wave generated), the ability to adapt (using continuous sound stimulation), etc., and by the structural characteristics of the sensor, the reaction of the left and right temporal lobe regions can also be known. situation.

Furthermore, it can also be applied to stimulate the human body to achieve effects such as changing physiological state, brain state, and state of consciousness. For example, a more common function is to achieve relaxation and improve concentration, for example, treating ADHD. (Attention deficit hyperactivity disorder), improve memory, change mental state, for example, treat PTSD (Post Traumatic Stress Disorder, which improves mental function and performance, for example, treating depression, altering brain state, for example, treating dementia, changing cognitive state, Various effects such as changing/inducing sleep state.

For this application, the ear-wearing structure has the advantage that it is located at the ear position. Therefore, it is only necessary to provide a sounding element (air conduction or bone conduction) in the ear wearing structure to provide hearing. Formal stimulation, the vibration module can provide the tactile form of stimulation, as for the visual form of stimulation, it can be achieved by extending the display component to the line of sight; or, further, with the glasses structure, The lens serves as a display screen, for example, by means of projection, or by placing the display element on the glasses. For example, the display element can be disposed at a position on one side, or both sides of the frame or the temple close to the eye, for example, LED, LCD , or other forms of display elements, etc., to produce flashes, color changes, etc., for visual stimulation; and in the case of both ear-wearing structures and eyeglass structures, the stimulation of the auditory and tactile forms can also be achieved by the eyeglass structure, for example The sounding element (air conduction or bone conduction type) can be arranged near the position where the temple is close to the ear, or can be attached to the frame or the temple The position of the head is set to the oscillator, etc., without limitation. Still further, electrical stimulation can also be generated by providing electrodes.

First, the ear-wearing structure/glasses based on the present invention are originally provided with electrodes, and therefore, are advantageously applied for electrical stimulation.

For example, common electrical stimuli include, for example, tCS (transcranial current Stimulation), TENS (Transcutaneous electrical nerve stimulation), MET (Microcurrent Electrical Therapy, micro) Current electrotherapy), as well as other known electrical stimuli, etc., wherein common forms of tCS include tDCS (transcranial Direct Current Stimulation), tACS (transcranial Alternating Current Stimulation), and tRNS (tRNS) Transcranial Random Noise Stimulation, and in particular, because transcranial electrical stimulation (current application range is usually less than 2 mA) is applied to the local physiology above the cerebral cortex, thereby affecting the corresponding cerebral cortex Activity, and the applied current is very weak, therefore, during the execution of electrical stimulation, the subject usually does not have a distinct sensation, wherein different cerebral cortical areas (as shown in Figure 1) are respectively managed Different functions of the human body, for example, the vision is mainly controlled by the occipital lobe area, the hearing is mainly controlled by the temporal lobe area, the body sensation is mainly controlled by the parietal lobe, and advanced cognitive functions such as language and self-awareness are mainly managed by the frontal lobe area. Therefore, by placing the electrodes on the skull corresponding to different cerebral cortical areas, in addition to obtaining the phase In addition to the activity of the cortical area, it is also possible to influence the cerebral cortex of the area by means of electrical stimulation.

There is also a type of electrical stimulation, Electrode stimulation of tongue. According to research, electrical stimulation of the tongue activates two major cranial nerves: the lingual nerve (part of the trigeminal nerve) and the chorda tympani (part of the facial nerve), while the stimulation of the cranial nerve is able to Produces flow of neural impulses that are transmitted to the parietal cortical somatosensory region and directly to the brainstem, where the brain stem is the control center for many vital functions, including sensory perception and movement, and then, starting from the brainstem These nerve impulses will pass through the brain and activate, or reactivate, neurons and structures associated with brain function - the cerebral cortex, the spinal cord, and, potentially, the entire central nervous system.

It is known that the application of electrical stimulation to the human body can achieve the effect of changing the physiological state. In addition to achieving the various functions described above, it is also known to contribute to the improvement of certain symptoms, such as local pain such as shoulder and neck pain, migraine, Depression, epilepsy, stroke, etc., where the sites used for stimulation, such as trigeminal, vagus nerve, sympathetic nerve, cerebral cortex, etc., as well as common shoulder and neck muscle soreness, are located near the head and neck. Adjacent to the position of the wearing structure used in the present case, for example, the contact position of the structure such as the ear wearing structure, the eyeglass structure, the neck wearing structure, and/or the head wearing structure, for example, the earlobe, the auricle, the ear canal, the back of the ear, The neck, the temple, the forehead, the apex, the back of the brain, etc., for example, many branches of the trigeminal nerve, for example, the auriculotemporal nerve is located near and above the ear, in addition, the supraorbital nerve, The supratrochlear artery nerve and the ophthalmic nerve are located near the eyelids and forehead, and these are just It is a position where the eyeglass structure/eyeglass structure is in contact with the ear/head. Therefore, it is quite suitable to be implemented by using the existing structure; in addition, the physiological state can be improved by electrically activating the acupuncture points. effect.

For example, it can be implemented in the form of glasses, directly through the two electrodes disposed on the structure of the glasses, for example, contacting the electrodes on both sides of the head, or contacting the area between the eyes and the electrode on the side of the head, so that the brain can be The part is electrically stimulated; in addition, it can be implemented in an ear-worn form, and the brain is electrically powered by an electrode disposed on the inner ear casing as described above and/or an electrode extending to an extending member behind the ear. Stimulation; in addition, electrical stimulation can also be performed through the neck-worn structure or the electrode on the head-mounted structure, and the neck-wear/head-on dual-use form as described above is also suitable for the electrical stimulation procedure; Using two wearable structures, for example, an ear-wearing structure with a head-on structure, or The ear-wearing structure is matched with the neck-wearing structure, or the ear-wearing structure is matched with the eyeglass structure. As long as the wearable structure is directly worn and the contact of the electrodes is completed, electrical stimulation can be performed. Therefore, the execution of the electrical stimulation can be made simpler and more convenient regardless of the form.

In addition to directly using the electrodes on the wearing structure for electrical stimulation, other embodiments may be used. For example, the wearable structure may be used as a medium to extend the electrodes for electrical stimulation. For example, only one extension may be extended. Electrode, and performing electrical stimulation together with one of the electrodes on the wearing structure, or extending two electrodes, and performing electrical stimulation through the two extended electrodes, is a feasible way, and when using the form of the extended electrode, Advantageously, the position of the selectable contact becomes more extensive and is not limited to the position in which the wear structure is placed. For example, as shown in Fig. 28a, the electrode can be extended from the temple of the eyeglass to contact the back of the neck, the ear After the forehead, forehead, etc., as shown in Figure 28b-28c, the electrode is extended by the ear-wearing structure to contact the forehead, the temple, the back of the neck, the back of the ear, etc. In addition, the head-mounted structure or the neck-wearing structure can also be extended by using The electrode increases the contact position at which the electrical stimulation can be performed, and therefore, there are various possibilities, and it should be noted that it can be implemented to extend only one electrode, or can be implemented as a delay. There are no restrictions on extending the two electrodes.

When the electrode is extended, the electrode can be placed on the skin by means of the attachment element 50, for example, a patch as shown in the figure, or the attachment element can be another wearable structure, for example, by a lens structure. Extending the form of the ear wearing structure, the neck wearing structure, the arm wearing structure, the wrist wearing structure, the finger wearing structure, or the ear wearing structure extending the eyeglass structure, the head wearing structure, the neck wearing structure, the arm wearing structure, and the wrist wearing structure , in the form of a wearing structure, or in the form of a head/necked structure extending out of the ear-wearing structure, the arm-worn structure, the wrist-worn structure, the finger-wearing structure, etc., all of which are feasible ways, and, alternatively, when implemented Two extension elements can be implemented as two extension elements They are respectively used for carrying, and can also be implemented to carry two electrodes simultaneously by one extension element, without limitation.

Here, it should be noted that the electrode used, whether it is an electrode disposed on the wearing structure or an extended electrode, may be implemented as a dry electrode or a wet electrode, for example, an electrode using a conductive paste. There is no limitation, and among them, it is particularly advantageous to use a self-adhesive wet electrode, for example, a patch electrode, to further improve the contact stability between the electrode and the skin in addition to the wearing structure, and there are many options for the form to be implemented. For example, it is possible to use a wet electrode by extending the form, or to replace the electrode of the original worn structure with a wet electrode.

In the case of a dry electrode, it is particularly advantageous to use a contact securing structure as described above, for example as a discrete electrical contact, and/or as a telescopic structure, in particular, The contact points near the head are likely to be blocked by the hair, and by using the contact to ensure the structure, the execution of the electrical stimulation will be ensured. Therefore, a suitable electrode type can be selected depending on the purpose of use, and there is no limitation.

In implementation, as shown in FIG. 29, a signal is generated by a signal generating unit 48 and transmitted to the electrodes 481, 482 connected thereto, thereby causing the electrodes to apply electrical stimulation to the user. By changing the electrical signal, the electrical stimulation applied to the user by the electrodes can be changed. Here, it should be noted that the generated electrical stimulation is a non-invasive form, and the content of the applied electrical stimulation may be changed according to the purpose of the electrical stimulation, for example, a sine wave, a square wave or the like may be selected. The current or voltage of the waveform changes, or in the case of pulse wave, even if the frequency is the same, the duration of the stimulus can be changed by Pulse Width Modulation; or, in the hope of using DC power for stimulation. In case, it can be straight It is also possible to use the galvanic current as an offset and then load the selected waveform thereon, so there is no limitation.

In addition, it is further advantageous that since the wearing structure of the present invention is originally designed to acquire an EEG signal and/or other physiological signals, the detection function of the physiological signal and the electrical stimulation can be combined on the same device. By combining this, it is equivalent to directly providing a means to confirm the effect of electrical stimulation, which is undoubtedly a more advantageous choice.

For example, one of the physiological states that changes due to electrical stimulation is the brain activity state, and the change can be known through the EEG signal. For example, as described above, the ratio of the alpha wave to the beta wave can be observed. In addition, we can understand the relaxation and tension of the user at the moment. In addition, the multi-channel setting can be used to know the activity and energy difference between the left and right brains. Furthermore, the potential difference between the left and right brains can be observed. In addition, the cortical slow potential ( SCP) can be used to understand the brain activity of concentration, and after understanding the state of brain activity, it can adjust various parameters of electrical stimulation, such as current, voltage, intensity, frequency, duty cycle, The duration is affected, and the brain is affected, and the purpose is achieved. Further, after the electrical stimulation is performed, the effect of the electrical stimulation can be known by understanding the change in the brain activity, and adjustment can be made as a basis.

Alternatively, electrodermal activity (EDA) is also an indicator of changes in physiological status. The electrical activity of the skin for electrical stimulation can be obtained through electrodes placed on the head or electrodes extending to other parts of the body, such as the neck, shoulders, wrists, and fingers, whether before the start of electrical stimulation, During the execution of electrical stimulation, and/or after electrical stimulation, a change in electrical activity of the skin can be observed as a reference for determining, and/or adjusting, the electrical stimulation pattern.

Alternatively, the physiological state changed by electrical stimulation can also be observed by detecting changes in heart rate. The heart rate is calculated to give the heart rate variability (HRV), and the heart rate variability is the best way to know the autonomic nervous system. Therefore, the purpose of electrical stimulation is to relax, improve attention, and improve. Mental state, improvement of sleep state, change of brain state, or treatment of certain symptoms, through the understanding of changes in autonomic nerves, can effectively control related physiological changes, and thus serve as a basis for adjusting electrical stimulation. Here, the heart rate can be obtained by arranging the light emitting element and the light receiving element, or the electrocardiographic electrode, without limitation, for example, the light emission can be set at the position where the eyeglass structure, the ear wearing structure is in contact with the head and the ear. The component and the light-receiving component, or may be disposed on the extended patch, the tape body, the neck-worn structure, the head-worn structure, the wrist-worn structure, and the finger-wearing structure, are all selectable positions, on the other hand, If the ECG electrode is used to obtain the heart rate, the two electrodes can be placed in two positions to obtain the ECG signal, for example, the head/ear and upper limb, the two ears, and the neck/shoulder and upper limb. At this time, it is also a convenient way to fix the wearing structure, or the patch or the belt body.

On the other hand, when detecting brain waves and discovering that the user is drowsing, the effect of reminding and preventing falling asleep can be achieved through the execution of electrical stimulation. For example, the user can choose to wear glasses and headphones while driving or studying. The neck wears the structure, etc., and monitors the brain waves to know whether there is drowsiness as a basis for generating electrical stimulation.

Here, it should be noted that when the detected physiological signal is an electrophysiological signal, the electrode for obtaining the electrophysiological signal and the electrode for performing the electrical stimulation may be further implemented to be shared with each other, for example, One electrode is shared, or both electrodes are shared, which simplifies the overall configuration.

The above-described implementation of the electrical stimulation based on the physiological state may have different implementation options. For example, it can be implemented by the signal generating unit to automatically control the generation of electrical stimulation, the mode of electrical stimulation, the parameters of electrical stimulation, such as duration, current intensity, voltage, frequency, duty cycle, etc., can also be implemented for use. The user can operate the device, for example, through the mobile phone screen, the display component worn on the wrist, the lens of the glasses, or the earphone, etc., to inform the user of the measured physiological state information, after which the user can determine himself through the operation interface. Whether to perform electrical stimulation, which electrical stimulation mode to select, or whether to adjust the parameters of electrical stimulation, etc., of course, can also be implemented to select an automatic or manual operation mode according to requirements, without limitation.

For example, a set of electrical stimulation modes may be provided for the user to freely select, or further implemented to first select a relevant electrical stimulation mode from the set according to the measured physiological state information, and then provide for use. The selection may be made, or it may be implemented so that the user can adjust the electrical stimulation parameter settings as described above, which are possible implementations, without limitation.

Therefore, electrical stimulation through the wearing structure does provide a way to make the implementation of electrical stimulation easier. If the physiological signal of the user can be obtained immediately, it is more helpful to improve the adjustment and selection of the electrical stimulation mode. And the effect that electrical stimulation can achieve, it is indeed a very advantageous way.

On the other hand, as shown in Fig. 30, on the premise that the ear-wearing structure and/or the eyeglass structure of the present invention can obtain an electroencephalogram signal, in particular, it can also be applied to perform physiological resonance stimulation (Physiological Resonance Stimulation).

First, a brain activity detecting unit 90 obtains an EEG signal for a specific time through the at least two EEG electrodes 100 and 102, and then performs a frequency domain analysis process on the acquired EEG signal through a processing unit 92. For example, through the Fourier transform, or by using a digital filter, the energy distribution of the EEG signal can be obtained, and then in different brainwave bands, for example, the δ band (0.1-3 Hz), the θ band (4-7 Hz). ), slow alpha band (8-9 Hz), middle alpha band (9-12 Hz), fast alpha band (12-14 Hz), slow beta band (12.5-16 Hz), intermediate beta band (16.5- 20 Hz), fast beta band (20.5-28 Hz), or other frequency bands, one or several peak energies during this time period can be observed, for example, an energy peak of 8 Hz in the alpha band , or an energy peak of 8 Hz and 10 Hz, and after selecting a frequency range, for example, selecting an alpha frequency band or a self-defined frequency range, a stimulation signal generating unit 94 can use the frequency within the frequency band. The frequency of the energy peak is used as a basis to generate a physiological stimulus Numbers, and applied to the user.

Here, it should be noted that the specific time can be implemented as instant, for example, the frequency domain analysis process is performed once every second or less, or for a longer period of time, for example, 5 minutes or longer. Time, then long-term segmentation to perform frequency domain analysis processing, then take the average value, or directly perform frequency domain analysis processing for the entire period of time, is a possible way, can be changed according to actual needs, there is no certain limit.

As for the decision of the frequency of the stimulation signal, the preferred way after the study is to select a frequency having a frequency proportional relationship with the energy peak. For example, if the frequency of the stimulation signal is assumed to be n and the frequency of the energy peak is m, then n and It is feasible that m is an integer proportional relationship. For example, n:m can be 1:2, 1:3, 2:3, 3:2, 3:1, etc., without limitation, so that through the two With the proportional relationship, it can be beneficial to achieve the entrainment and thus the resonance phenomenon.

Here, it should be noted that as long as the peak energy frequency and the frequency proportional relationship are determined according to the above method, a slight offset can be tolerated in actual implementation, which is within the scope of the creation, and there is no limitation. The stimulation signals having different proportional relationships may be mixed, for example, the mixing ratio relationship is 1:2, and the 1:3 stimulation signals are respectively transmitted to transmit synchronization/resonance through multiple harmonic components, and The mixed signal ratio, intensity, and type can also be implemented to change over time. Further, when implemented to provide an auditory stimulus, music can be further blended, for example, natural sounds to increase user acceptance. Therefore, there are various possibilities and no restrictions.

When resonance is reached, one of the possibilities is to increase the peak energy of the target. For example, the selected 8 Hz energy peak will increase the amplitude, and the other may be the energy in the selected frequency band. The frequency of the peak has an effect, for example, when the resonance is reached, by changing the frequency of the externally applied stimulus, for example, from 8 Hz to 9 Hz, to transmit the traction force between the two through the resonance, so that the energy peak The frequency is thus changed, so that the traction effect of changing the original natural frequency can be achieved by gradually increasing or decreasing the frequency of applying the stimulation frequency.

Further, by increasing the target peak energy or by changing the frequency of the supplied stimulation signal to achieve the frequency of pulling and affecting the peak of the energy, it is possible to obtain a change in physiology, or brain state, and/or Or the effect of the state of consciousness, for example, various physiological states of the human body such as sleep state, awake degree, degree of relaxation, meditation depth, etc., and diseases related to brain activity, such as epilepsy, migraine, etc. There is a positive effect.

There are various possibilities for the type of stimulus signal. For example, visual stimulation signals, auditory stimulation signals, or electrical stimulation signals are all feasible methods. For example, the visual stimulation signal can be a video signal with a proportional relationship of the blinking frequency. For example, it may be implemented in the form of a flash using LEDs, LCDs, or other display elements. The auditory stimulation signal may be an audio signal having a proportional change in the frequency of the sound, for example, a sounding element (air conduction or bone conduction) may be utilized. And in a special embodiment, the generation of the auditory stimulation signal is achieved by two sound generation sources, that is, by using a so-called Binaural beats method, by providing Two auditory signals having a frequency difference, and the frequency difference is proportional to the frequency of the target peak, and when the two auditory signals are simultaneously fed into the brain, the brain eventually produces a feeling of having the frequency difference The effect of a third auditory signal, and such two sound generating sources, there are various embodiments, for example, can be set separately in two The sounding component in the earwear structure is achieved; the sounding component can also be separately disposed on the temples on both sides of the eyeglass structure, which is especially suitable for the bone conduction sounding component, so that the eyeglass structure will not be too a large change; or, the sounding element can also be disposed on the earwear structure extending from the spectacles structure, for example, two ear-wearing structures can be extended from the single-sided temple foot, or one ear can be extended from each of the two mirror legs. Wearing a structure to be placed on both ears can be implemented.

Electrical stimulation also has different implementation forms. As mentioned above, the type of electrical stimulation can be changed by selecting different currents and voltages to apply waveforms. In addition, electrical stimulation can also select the location of stimulation, as described above. Transcranial electrical stimulation, transcutaneous electrical stimulation, or electrical stimulation through the tongue, etc., therefore, there are various possibilities.

Furthermore, in addition to applying a single stimulus, more than two types of stimulation can be applied simultaneously. For example, the same implementation of visual stimulation and auditory stimulation, or simultaneous application of electrical stimulation and auditory stimulation, or simultaneous electrical stimulation of different cerebral cortex regions, are optional implementation methods, in addition, the second stimulus source It can also be implemented by an external device, for example, a light source, a sound source, a mobile phone, etc., without limitation, and in this case, the frequencies of the plurality of stimuli can be the same or different, without limitation, and only need to have a frequency with the energy peak. The proportional relationship can be.

Then, after stimulation by means of resonance, the detection of the EEG signal can also be used to observe the effect of the stimulus during the stimulation period and/or after the stimulation, for example, whether the energy of the target peak is Increase, and/or its magnitude of increase, etc., and thus, the manner in which the stimulus is performed can be changed instantaneously when the effect is not achieved, for example, when the magnitude of the energy increase is less than expected, the intensity of the stimulus can be enhanced, or Increasing the time of stimulation, or changing the waveform of the stimulus signal, can help increase the stimulating effect.

Such a resonance stimulation method can accurately perform resonance stimulation on the brain wave frequency of the human body to achieve an enhanced effect, and can be adjusted immediately, which is a very efficient physiological stimulation mode.

Here, similarly, the type of the resonant physiological stimulus applied, the mode of execution, the parameter setting, and the like may be implemented to allow the user to select, for example, the input provided through the ear wearing structure and the eyeglass structure. The operation interface, for example, a button, a touch interface, a light sensor, a voice control, or the like, or an external device that communicates with the earwear structure/glass structure, for example, an operation interface of a mobile phone or a wrist worn device, and The physiological state change caused by the application of the resonant physiological stimulus can also be provided to the user through an information providing unit provided on the ear wearing structure/glass structure or an external device communicating with the ear wearing structure/glass structure, for example Through Visual, auditory, tactile and other forms help users to understand their current physiological state and help brainwave resonance.

In a particular embodiment, as shown in Figures 31a-31b, it is implemented in the form of a headband disposed on the top of the head in the form of an in-ear housing or earmuffs of both ears. Such an arrangement is well suited for obtaining the brain. The electroencephalogram of the cortical parietal region, wherein, as shown in the figure, when the ear-wearing structure is implemented in the form of an in-ear housing, the coupling between the ear-wearing structure and the head-wearing structure is mainly implemented by the connecting line, and when the ear is When the wearing structure is implemented in the form of an earmuff, the combination with the wearing structure is mainly implemented in a form in which the two are integrated, but it is not absolute, and other embodiments are also feasible.

In the implementation, as shown in the figure, the two electrodes 191, 192 can be placed on the head corresponding to the position of the parietal lobe of the cerebral cortex to obtain the EEG signal, or a set of the ear-wearing structure can be further disposed. The electrode is used as a reference electrode to obtain a two-channel electroencephalogram signal by using a reference combination paradigm with the two electrodes on the top of the head, or alternatively, one electrode is disposed on the headband, and one electrode is disposed on the ear-wearing structure. Obtaining an electroencephalogram of the parietal region of the cerebral cortex; alternatively, the electrode can be placed close to the cerebral cortex and temporal region, for example, the position of the headband close to the ear, or the ear-wearing structure, especially for the ear. In the form of a hood, the brain electrical signal of the cerebral cortex and temporal region can be obtained, and therefore, it can be changed according to actual needs without limitation. In addition to being used to obtain EEG signals, electrodes can also be used for electrical stimulation, for example, transcranial electrical stimulation, resonant physiological stimulation, etc., or electrical stimulation electrodes can be provided using attached components, for example, extending from a head-mounted structure or Ear wear structure. Further, in order to overcome the electrode contact problem that may be caused by the hair on the head, the electrode disposed on the headband is preferably implemented to have a contact securing structure as described above, and on the other hand, the electrode can pass through Hair, on the other hand, also increases the range of contact.

Since it is in the form of a commonly used headset, it is also quite suitable for setting the sounding component (air conduction or bone conduction) in the earwear structure, so that the user audio can be naturally provided. For example, it is used to play music stored internally, for example, an mp3 sound file, or to play music from an external device, or to provide relevant physiological information, operation information, etc., for example, for physiological feedback/breathing Training, etc., or, further, can also be used to perform physiological stimulation, for example, various types of auditory stimuli described above, and since the sounding elements can be provided on both sides, it can also be implemented to utilize the above-described two-channel beat frequency method. Perform physiological stimulation.

Therefore, under this framework, not only can you get EEG signals and/or perform electrical stimulation, but also provide audio and/or perform auditory stimulation. In addition, it is a common form of earphones. The user's acceptance is quite high. Have an advantageous choice.

Such a form, as long as it is soft and comfortable, is quite suitable for use during sleep. During sleep, by detecting brain signals, you can understand brain activity, such as rapid eye movement, deep sleep, etc. In addition to providing music that helps sleep, it can also be used to determine various stimuli applied to the brain. For example, electrical stimulation, auditory stimulation, etc., and as described above, the stimulation applied to the human body has an effect of improving/inducing a sleep state, and therefore, through such a configuration, various stimulation modes described above can be naturally achieved, which is quite advantageous; Further, other physiological sensing components may be added to obtain other physiological signals. For example, a blood sensor may be used to obtain a blood physiological signal, thereby obtaining information such as heart rate, respiration, blood oxygen concentration, and the like. Other electrodes can obtain physiological signals such as EO, EMG, and skin electrical signals, or add a microphone to learn about breathing, snoring, Sleep Apnea, etc. Information, which helps to understand sleep conditions in more detail, and, in addition to being used to adjust physiological stimuli, can also record physiological signals for sleep diagnostic analysis.

In addition, based on the detection of EEG signals and/or other physiological signals, it is also possible to observe physiological signals by observing physiological signals before performing electrical stimulation and/or resonance stimulation, and then whether or not to perform stimulation. Determine the basis on which and/or what stimulus to perform.

Among them, if the purpose of stimulation is to relax, improve concentration, change mental state, change/inducing sleep state, change brain state, for example, cognitive state, etc., first observe the brain wave or other physiological signals. It is helpful to know whether the physiological state is in a stable physiological state to determine whether the stimulation can be started, and/or which stimulation is to be performed, which may help to achieve the stimulation effect more quickly.

For example, by observing the brain waves, it can be known that the user is currently in a state of relaxation or tension. For example, the α wave predominance indicates that it is in a relaxed state, and the β wave predominance indicates that it is in a state of tension; on the other hand, if it is set Other physiological sensing components can be used to understand the physiological state of the user through other physiological signals. For example, the light sensor can obtain the user's heart rate, and the RSA phenomenon can be used to know the user's respiratory rate and utilize the heartbeat variation. The rate is known to the activity of the autonomic nervous system, and/or to observe the coherence between heart rate and respiration, etc., and these can represent whether the user is in a stable physiological state.

Through such prior observation, you can use the method of setting the preset conditions first, and let the stimulation be performed in the most effective way. For example, if you observe the brain wave, you can observe it for a period of time or more. Between the segmentation time, whether the energy distribution in a specific frequency band is stable, or whether the energy peak is consistent, etc. If the heart rate is observed, the heartbeat frequency can be observed. Whether the respiratory rate, the heart rate variability, the heart rate, and the coherence between the breaths fall within a preset range.

Further, if the user is in an unsuitable physiological state, for example, a relatively unstable physiological state, the user may be placed in the physiological feedback, and/or the respiratory guidance/breathing training program as described above. After a stable and relaxed physiological state, resonance stimulation/electric stimulation is performed to make the overall procedure more effective. Therefore, there are various possibilities and no restrictions.

The decision process can be implemented to be performed on the wearable device or to transmit the physiological signal to the external device, and the external device can perform the process, for example, transmitting the physiological signal to the mobile phone through wireless transmission, and using the application in the mobile phone. To calculate and decide whether to perform the stimulus and what stimulus to perform.

Here, it should be noted that, as is well known to those skilled in the art, the spectacles structure is a type of head-mounted structure, and therefore, the spectacles structure used in the above-mentioned stimuli-related description is also suitable for use in a head-mounted structure. The basic device, whether it is used to obtain physiological signals or to perform stimulation, is therefore within the scope of this creation.

Another common application is as a Human Machine Interface (HMI), for example, by analyzing the EEG to analyze the user's intention, or detecting the user's physiological changes, and then converting In order to operate the instructions, in recent years, such human-machine interface and physiological feedback have also been applied to games, for example, by allowing the user to concentrate on the presentation through the presentation of the game.

Since the sensor according to the present invention is in the form of earwear or glasses, it is also suitable for use as a human-machine interface, and in the case where the detected physiological signals include an electroencephalogram signal and a heart rate sequence, a manner in which instructions can be generated There are several possible ways, for example, but not Limitation, because the proportion of alpha waves in brain waves varies greatly with the movements of closed eyes and blinks. Generally speaking, when the eyes are closed, the proportion of alpha waves is greatly increased. Therefore, it can be generated. The basis of the instruction, in addition, when the brain electrical electrode can detect the action of the eye and obtain the EOG, the instruction can be issued by, for example, blinking, moving/turning the eyeball, etc.; Since breathing is also a physiological activity that the human body can control, as mentioned above, breathing not only affects the heart rate (that is, the so-called RSA), but also causes fluctuations in the brain wave in the low frequency section. Under the framework of this creation, whether it is detecting brain wave signals or detecting heart rate sequences, it is possible to know the change of the user's breathing behavior pattern, and thus as a basis for generating instructions, for example, the user can The command may be given during a long inhalation period, or the heartbeat variability may be increased by deepening the breathing, thereby increasing the effect of the RSA amplitude as a basis for issuing instructions, and other physiological signals may be used as Order basis, for example, electromyography signals (EMG) can tell whether the muscle contraction force, through the left and right side teeth can bite hard and were issued a directive, therefore, there are a variety of possible, there is no limit.

Further, further, when the sensing element is coupled, for example, an Accelerometer, a G sensor, a gyroscope, a magnetic sensor, etc., More instructions are given, for example, when the various physiological phenomena described above can be combined with the action of nodding, turning the head to the left or right, or the movement of the hand, for example, the motion sensing component can be placed on the wrist wearing structure or finger By wearing a structure, to know a specific gesture, or a static posture change of the hand, a variety of instructions can be combined to make the application wider, for example, applicable to games, etc., which are very suitable.

In summary, the ear-wearing and eyeglass-type brain activity sensors according to the present invention are transparent. Over-contact with the novel EEG sampling position, ie, the position of the ear wall, the tragus, the tragus, the tragus, the back of the auricle, and/or the V-shaped depression between the auricle and the skull, can provide different The stable electrode strength parallel to the bottom of the ear can be achieved by the conventional technique, and the contact can be completed through the wearing action, and the additional structure can be used to provide a stable contact, which is quite helpful for obtaining high-quality brain telecommunications. number.

Moreover, many applications are more convenient through such an arrangement. For example, an ear-wearing structure/glass structure can be used as an interface for providing physiological stimulation, and physiological stimulation can be adjusted according to the obtained physiological signal, not only by wearing form.
