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 wearing 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 through 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 Cenang area; in addition, many patent documents revealed The use of the ear as a means of taking the position of the EEG signal, for example, US20070112277 discloses the use of earplugs in the ear canal as the setting of the brain electrical electrode medium; US20120209101 discloses the use of an ear-shaped hearing aid as a medium for setting the brain electrical electrode; US8565852 discloses the structure through the earloop A method of achieving a fixed electrode effect in conjunction with an ear clip; 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 an electrode.

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 US2006/009497, a reference electrode is disposed on the earlobe by using a conventional clamping method, and the detecting electrode (detection electrode) The electrode is fixed by the physiological structure of the auricle. Although this method is good, it is obvious that the detection electrode is actually difficult to be fixed due to the almost complete lack of fixed force, and the electrode is in contact with the skin. Unstable, it is easy to shake due to head rotation, movement, etc., directly affecting the quality of the acquired 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 in which the electrode is disposed in the ear canal, the method of disposing the electrode on the surface of the rear ear housing to contact the skull is also disclosed, which is in the ear-wearing brain activity detecting device. Very common setting and contact position, however, such a structure does not easily cause the rear ear shell to generate a force toward the cranial direction, so usually the rear ear shell It is only maintained behind the ear, it is very easy to sway, 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.

Accordingly, it is an object of the present invention 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 achieve stable contact with the concha wall of the auricle, thereby facilitating the acquisition of the EEG 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, which utilizes An in-ear housing that at least partially conforms to the shape of the ear and/or between the tragus, such that the reference electrode thereon can achieve stable contact with the tragus and/or the tragus between the tragus and thereby be obtained together with the motion detecting electrode EEG signal.

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.

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

It is still another object of the present invention 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, thereby serving as physiological feedback and/or breathing training. in accordance with.

It is still another object of the present invention to provide a brain activity sensor that further has an electrocardiographic electrode to obtain an electrocardiogram, thereby providing electrocardiographic related information.

It is still another object of the present invention to provide an ear-worn electrode structure that achieves a stable bond of the electrode to the ear canal through the arrangement of the elastic material.

It is still another object of the present invention 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 still 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 transmits glasses The structure or ear-worn structure is set up as support 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. The inside of the skull corresponding to the auricle 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 the distance from the brain. The cortex is farther away, and the interval between the ear canals is increased. Therefore, the lower the EEG signal strength becomes weaker. Therefore, in the present invention, in principle, the ear canal is divided and the upper auricle portion is regarded as The position of the EEG signal can be measured, which is suitable for setting the activity detection 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 using 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 conventional 10-20 system, the position of the T7/T8 is matched with the electroencephalogram obtained by the reference electrode on the earlobe, and the lower view shows the movable detecting electrode disposed on the upper side of the same side of the auricle, and the reference electrode is disposed on the reference electrode. The EEG obtained by 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 beyond the skull, mainly composed of skin covered cartilage, which is located at the lowermost position. The earlobe (also known as lobue) contains only subcutaneous tissue; the inner face of the auricle (concave side) includes various raised and recessed areas as shown.

According to the concept of the present invention, 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 of the present invention described above, will provide a means of securing that more readily achieves stable electrode contact.

For example, in the inner surface of the auricle, around the superior concha and the inferior concha, there is a concha floor (ie, parallel to the plane of the skull) upwards. A façade area connected to the antihelix and the antitragus, called the concha wall, whose natural physiological structure provides a continuous façade that protrudes from the bottom of the ear. Therefore, when this region is used as the electrode contact position, the force required to fix the electrode will be different from the radial force of the prior art, that is, the force parallel to the bottom of the ear; in addition, immediately adjacent to the ear Below the wall, the intertragic notch between the tragus and the tragus, and the adjacent tragus, also provides a contact area that protrudes from the bottom of the ear. Therefore, in the present invention, the armrest wall, the tragus, the tragus between the tragus, and the continuous façade region 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 area of the façade extends from the upper part of the auricle to the underside of the ear canal, the area above the ear canal can be used as an activity detection based on the experimental results mentioned previously. The contact position of the electrode, for example, the arm wall above the ear canal, and the area below the ear canal is the contact position that can be used as the reference electrode, for example, the arm wall below the ear canal, the ear arm wall near the tragus, For the tragus, the tragus between the tragus, and 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 provide a grounding electrode, which 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 invention 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, it can be placed in the ear of the inner surface of the auricle. The housing will be the primary choice, and there is no limitation as to which shape and form to use, as long as stable contact is achieved with the façade area, for example, Figures 4a-4c illustrate preferred implementations in accordance with the present invention. A schematic view of the inner ear shell of the example combined with the inner surface of the auricle, which respectively indicates that the inner ear shell 10 is in contact with the ear body wall, the tragus, the tragus between the tragus, and/or the area formed by the tragus, The case of the upper half and the lower half of the facade area.

Here, in particular, in the present invention, the in-the-ear housing is preferably fixed by a radial mutual abutment between the structure of the armor boat and/or the armor cavity, 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 while fixing the inner casing of the ear The effect of stabilizing the electrode contact is also achieved.

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 types of earphones that are commonly found on the market are applicable to the present invention. As you know, when the earphones are placed in the inner surface of the auricle, they will naturally touch at least the tragus, the tragus between the tragus, or the position of the tragus. Then, depending on the actual shape, decide whether or not There is contact between the ear arm walls, so the electrodes can be placed at these positions. In addition, when the earphone has a portion extending into the ear canal, the fixation effect can be increased to help maintain stability in the inner surface of the auricle.

Therefore, similarly, the in-ear housing of the present invention can be similarly selected when implemented, and can be fixed only by the radial abutment between the housing 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 it has 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, as shown in Figures 4a-4c and 6a. Each of the various in-ear housings can have one of the electrodes disposed on the surface of the bottom of the contact 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. Connecting the electrode 100 and the conductive portion 121 by using a connecting wire, and connecting the same The conductive portion 121 and the circuit 104; or the conductive portion 121 and the electrode 100 may be connected differently. For example, as shown in FIG. 7b, the two may be disposed in contact with each other. A conductive substance 142 can also achieve the effect of electrical connection, and such a way is more helpful to maintain contact between the electrode and the ear canal, which is 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 embodiment, that is, the electrode and the conductive material are made of the same conductive material, that is, the two can be integrally formed, and thus, as shown in FIG. 7c, The elastic member is formed by combining two materials, an elastic material portion 143 and a conductive material portion 144, wherein a portion formed of a conductive material is simultaneously used as an electrode and a conductive portion, and a portion formed of an elastic material is used as an elastic member. The main body is used to provide elastic restoring force to ensure that the conductive material portion 144 is in contact with the ear canal; in this case, if the conductive material is also selected to have elasticity, for example, elastic conductive rubber, elastic conductive silicone, elastic conductive foam In cotton or the like, 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, Its 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 no In this case, it should be noted that, as shown in FIG. 7e, it is possible to dispose the electrode 100 on the surface on which the protrusion is exposed without using a conductive material to form the support body. Therefore, there is no limit.

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 if the support is formed of a conductive material, it is only necessary to connect to the circuit. Alternatively, 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, which is convenient in any way. 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.

Yet another implementation may be to implement the conductive elastic member as shown in Figures 8b-8c In order to have two parts, a first part 146 and a second part 148, and the two parts are electrically insulated from each other by an insulating part 147, so that the same elastic part can also provide two mutual insulation. a conductive region, so when actually applied to the measurement, one of the implementation options may be: coating the outer surface with an insulating coating, and exposing the first conductive region and the second conductive region to the first portion and the second portion, respectively, to Alternatively, as the two electrodes, the first one may be formed by disposing a conductive material, for example, a metal conductive sheet, or a conductive fiber, on the surfaces of the first portion and the second portion, respectively. The electrically conductive region and the second electrically conductive region, wherein the first portion and the second portion function as the conductive substance 142 as described above, and therefore, may be selected according to actual measurement requirements, without limitation.

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 placed on the part that enters the ear canal and the other electrode is located on the outside of the ear canal. Divided, or both electrodes are located on the portion outside the ear canal, or both electrodes are located on the portion of 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. a hollow portion 12, such that the shape of the inner casing can be freely expanded and contracted according to the shape of the space to be placed, adapting to different ear shapes of different users, and allowing the electrode 100 located thereon to 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 to 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 can be formed as a plurality of discrete contact points, for example, implemented Parallel to each other, so that no matter which contact point is touched, it can be regarded as the contact between the electrode and the skin has been completed, which is quite convenient, and this is especially suitable for the contact surface having the curvature, or may be slightly In the case of movement, it is further advantageous if the discrete contact points can be implemented to be scalable, for example as shown in Figure 11b, in the form of a spring thimble to further ensure contact, for example The contact between the skin and the electrode can be achieved by compressing the spring ejector pin, so that even a small distance displacement between the skin and the electrode 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 a spring-loaded electrode as described above to overcome the thickness of the sleeve member, or also to be formed directly on the sleeve member, and when the sleeve is sleeved on the housing The electrically conductive contact portion on the electrical connection is an implementable manner and is not limited.

In the embodiment shown in Figures 13a-13c, the extension member can be placed over the top of the canine The armor wall, and as can be seen from the figure, in the actual implementation, the shape of the extension member can have various possibilities. For example, the extension member of Fig. 13a is finer and has better flexibility, and the figure 13b is The extension member has a better supporting force because it is wider, or it can also form a ring shape as shown in Fig. 13c, and therefore, there is no limitation.

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 In the position, especially when there is a tilt to provide a component force toward the skull, the upper edge of the inner casing of the ear will naturally contact the partitioning protrusion, which will be very helpful in achieving the position. The electrode is in contact with 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, the in-ear housings on both sides have two electrodes, a reference electrode and a motion detecting electrode, and then pass through two sets of reference electrodes and active detecting electrodes respectively located on different ears. The two-channel EEG signal can be obtained, or the reference electrode can be placed on the single-sided inner ear casing, and the two-channel EEG signal can also be obtained. It can then be used, for example, to monitor the activity of the left and right brains, which is also a highly advantageous implementation.

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 the present invention, 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 more easily achieved, and such a situation coincides with the novel contact position proposed by the present invention.

As shown in Figures 14a and 14b, an earhook structure in accordance with 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 With Relatively exerting 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 have a curvature more conforming to the back surface of the auricle, and the stability of the electrode contact can be increased as well; or the extension member can be made of an elastic material, and the electrode can be increased by the elasticity of the material itself. The contact stability, for example, creates a force that sandwiches the auricle with the front part of the ear through elasticity. Therefore, there are various possible implementations, without limitation.

Therefore, by selecting the appropriate extension part and the appropriate relative force The requirements for different electrode contact positions, for example, the back skin corresponding to the position of the arm wall inside the auricle, and the skin behind the auricle near the earlobe, etc., are all easily accessible to the extension member. A stable position can be achieved, which is quite convenient in production 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.

Other embodiments may be used in addition to the above-described in-ear housing and ear-hook form.

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 magnetic, can have each Implementation is possible, no restrictions. 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 suitably implemented to be achieved 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 portion of the temple falling behind the auricle will contact the skin behind the auricle, and in these positions there is exactly the electrode contact position as claimed in the present invention, whereby the electrode according to the present invention Naturally suitable for implementation on the structure of the glasses, and through the action of wearing the structure of the glasses while simultaneously completing the contact of the electrodes, is also a relatively convenient choice, and because the support structure of the eyeglass structure and the head includes at least two auricles and a nose, etc. The contact position can be stably set on the head without sloshing, and therefore, it is also possible to naturally exert a stable force on the contact between the electrode and the skin, which is a quite advantageous embodiment.

The spectacles structure described herein refers to a wear structure that is placed on the head by the auricle and the nose as a support point and that comes into contact with the skin of the head and/or the ear. Therefore, It is limited to the general eyeglass structure, and includes its deformation. For example, it may be a structure with a clamping force on both sides of the skull, or an elastic continuous body without a pivoting axis of the temple, as shown in Fig. 23d, or with an extension. The structure of the temples to the occipital region of the back of the brain, or alternatively, can be implemented as an asymmetrical form of the temples on both sides, 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. Above the auricle, or in order to increase the fixing effect, a strap connecting the two temples may be provided, 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 part of the area between the eyes, are considered part of the nose pad, in addition, there is no limit to the position of the head / ear contact, for example, some glasses for practical use needs or styling, for example, VR glasses, It is implemented to contact other parts around the eye, so there are various possibilities and no restrictions.

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, etc.) is placed. 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 Figure 22b, the additional structure can be implemented as And the glasses structure are electrically connected to each other, and the electrode 202 thereon is subjected to signal extraction together with the electrode 200 on the eyeglass structure, or, as shown in FIG. 22d, the additional structure may also be implemented to have two electrodes 200 at the same time. 202, and is disposed on the auricle by combining with the spectacles structure, the two methods are obtained by contacting the one-sided auricle; on the other hand, the additional structure can also be implemented in plural, for example The double-sided temples are combined with an additional structure, and the signals are extracted by respectively contacting the electrodes with the two auricles and/or the heads in the vicinity thereof. In this case, the electrical connection between the two additional structures can be The eyeglass structure is achieved, or the additional structure may be connected by using a connecting wire, and the required circuit may be partially or completely disposed in the eyeglass structure or the additional structure according to requirements; in another aspect, the setting position of the additional structure is not limited After the ear, for example, it can also be placed at the side of the head in front of the ear, or at the same time in front of the ear and behind the ear, as long as it does not affect the user, there is no limit; on the other hand, the additional The structure may also be used only to set up the circuit to drive the electrodes on the glasses for signal extraction after electrical connection with the spectacles structure; further, the additional structure may be implemented in a removable form for the user to have Optionally, additional structures can be bonded to the spectacles structure for measurement as needed.

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 In addition to the shape of the V-shaped depression, especially when hair is likely to appear at the electrode contact position, structural design such as dispersion, protrusion, expansion and contraction can help to pass through the hair, and the contact difficulty between the electrode and the skin is lowered. Figure 22f shows a situation in which a plurality of discrete telescopic forms of electrodes are provided on the temples. In addition, by implementing the electrodes as a plurality of discrete contact points, the range of the electrodes can be expanded thereby facilitating overcoming The difference in size between different user heads is quite advantageous.

Here, it is to be noted that although specific embodiments of the invention have been described, it is understood that these are by way of example only, and not limitation, as the Inter-contact spectacles or ear-wearing structures are within the scope of the invention, and various embodiments may be combined without limitation.

In addition, since the present invention is intended to provide a way for a user to obtain an EEG signal through the wearing method at any time, it is preferably in the form of a dry electrode, for example, a conductive gold. Genus, conductive rubber, conductive silicone, 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 in which an inner ear can be contacted is small, but due to the spatial separation of the physiological structure of the ear canal, an EEG signal sufficient for analysis can be obtained even at a very small distance.

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 wear, a spectacles, a head wear, a wrist wear, or an arm wear, etc., or an inner ear shell It can also be directly implemented to include the required circuit therein, so it can be changed according to actual needs, and there is no 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 position of the parietal lobe, the prefrontal lobe, and/or the occipital lobe, and preferably, the electrode on the in-the-ear housing is implemented as a reference electrode; in addition, the electrode on the in-the-ear housing may also be implemented as a detecting electrode and matching a reference electrode disposed inside the ear clip on the earlobe (as shown in FIG. 16c); of course, an electrode may be disposed on each of the bilateral in-ear housings, for example, as one The electrode on the inner casing of the ear adopts the configuration of the reference electrode (ie, the lower part of the contact auricle), and the upper electrode of the other inner ear shell is configured with the movable detecting electrode (ie, the upper part of the contact auricle), however, Note that since there is a sufficient distance between the two ears, the position of the electrodes is not limited, so that the two ear inner casings are in contact with the upper or lower part of the auricle, and an EEG signal sufficient for analysis can be obtained. For example, one can contact one of the inner casings 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 shown in Figure 6b), 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 other end of the ear On the electricity The poles at the bottom of the ear contact or the electrodes on the inner casing of the two ears are in contact with the bottom of the ear, so there are various possibilities and no restrictions.

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, or the like, disposed at a position such as a parietal lobe, a prefrontal lobe, and/or a occipital lobe, and preferably, the electrode on the extension member is implemented as a reference electrode; or, instead The electrode on the extension member can also be combined with the reference electrode disposed on the earlobe by the ear clip to obtain an electroencephalogram signal. Alternatively, one electrode can be disposed on each of the bilaterally extending members, for example, one side can be implemented as a reference electrode (ie, Contact the lower part of the back of the auricle), the other side as the motion detecting electrode (ie contact V-shaped recess and / or the upper part of the back of the auricle), however, similarly, due to the sufficient distance between the two ears, the electrode setting position Without limitation, whether it is the contact member extending on both sides of the upper or lower partial auricle, can obtain sufficient EEG signal analysis, there is no limit.

Further, Figures 18a-18d show other possible embodiments in accordance with the present invention, wherein Figure 18a illustrates the tragus or tragus notch between the inner ear shell and 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, Figure 18b illustrates the inner surface of the ear canal contacting the inner surface of the auricle The upper arm wall and the extension member are in contact with the lower part of the back of the auricle. Alternatively, the electrode on the inner ear can be connected to the bottom of the ear (as in the case shown in Fig. 6b). And the electrode on the extension member contacts the V-shaped depression or the skin of the skull, or the skin contacting the back of the auricle; or alternatively, it may be implemented to extend the ear clip from the extension member to place the electrode on the earlobe, The EEG signal is obtained by contacting the inner surface of the auricle with the inner ear shell to contact the upper part of the 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 the extension member can be moved up and down by providing an adjustment mechanism, 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 located on the inner ear housing is implemented as the reference electrode 202 to contact the position of the tragus and/or the tragus notch, and contact the V-shaped recess and/or The electrode at the back of the auricle is implemented as a motion detecting electrode 200 that can contact the V-shaped recess and/or the skin on the back of the auricle or the skin of the skull, without limitation; in yet another preferred embodiment, as in 18d As shown, the extension member is embodied to be positioned below the insole housing such that the electrode thereon contacts the lower portion of the auricle, for example, the auricle back skin above the earlobe, and can also be lowered by providing an adjustment mechanism. The effect of moving up increases 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 , simply by rotating the entire ear The way of wearing the structure, for example, rotating around the cylinder, adapts to different auricle sizes of different users, for example, Figure 19b shows the situation on a larger auricle, and Figure 19c is In the case of being placed on a smaller-sized auricle, it can be seen from the figure that 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 to different auricle sizes while ensuring The contact between the electrode and the skin, of course, in order to make the preparation easier, the entire outer surface of the cylinder and/or the entire surface of the extending member facing the V-shaped recess may be directly implemented as an electrode, for example, Made of a conductive material, there are a variety of possible options, no limitations.

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.

When the extension member described above only provides an electrode function, that is, when most of the circuits are disposed in the in-ear housing, the extension member may further be implemented to be removable from the in-ear housing. The form, for example, is achieved by setting a connection port, so that the benefits of convenient storage and carrying can be achieved. 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 the electrode contacting the lower half of the back surface of the auricle. Suction, the other electrode is carried by an extension member extending from the inner casing of the ear to contact the v-shaped depression and/or the upper part of the skin of the auricle, here, in particular, the extension member and the inner ear shell The body can be implemented with an adjustment mechanism 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 even if the extension member is adjusted by the mechanism The displacement does not affect the contact position of the lower electrode. In this way, 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, Advantageously, the extension member extending from the inner housing of the ear can also be embodied to be curved along the shape of the auricle, for example, directly as a connecting line, or made of an elastic material, etc., so that when When the electrode contacting the lower side of the back of the auricle is fixed by the magnetic attraction between the inner ear and the inner casing, the electrode contacting the V-shaped recess and/or the upper part of the back of the auricle may be disposed just above Between the profile and the skull, the contact can be made more stable by the pulling force generated by the magnetic attraction, and further, the extension member can also be implemented to be replaceable, for example, by changing different lengths or different materials. To adapt to 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 circuits required to obtain the signals, such as the processor, the battery, etc., and the wireless transmission module can be placed in the front part of the ear, or placed in a housing behind the ear, or set In a host connected through a connecting line, it can be worn on the body, for example, in the form of a wrist-worn, a neck-worn, a head-worn, a spectacles, or an arm-worn, etc., and can also be changed according to actual needs without limitation.

In a preferred embodiment, in particular, the host can be further configured to accommodate both the neck and the head, whether in a form that is simply placed in the ear or in the form of an extension member. A wearable structure, as shown in Figures 24a-24c, that is, the wearable structure can be selectively placed on the neck or the head according to the needs of use, and the wearable structure can be selected when worn on the head. It is placed in front of the forehead (Fig. 24c), placed on the top of the head, or placed behind the head, without restrictions.

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 is shortened, and the movement of the hand is not affected by the wiring, which increases the convenience of use. In addition, the host is placed in the inner casing of the ear, or the main body is placed behind the ear. In such a way, in addition to reducing the burden on the ear, the setting stability can be increased by reducing the volume of the inner casing of the ear, and such a neck-shaped shape The style is the same as wearing a necklace, and the user is quite easy to adapt.

Moreover, when implemented as a head-wearing form, the position of contact with the head is increased, so that the possibility of obtaining more brain signals of the cortex of different brain parts is also increased, and therefore, the user can also select differently. The position and position of the EEG signal obtained by the user. For example, refer to Figure 1. When the electrode is placed at the forehead position, the EEG signal of the frontal lobe can be obtained. When placed above the head, the parietal lobe can be obtained. The electric signal can obtain the electroencephalogram signal of the occipital lobe when it is placed behind the head, and the electroencephalogram signal of the temporal lobe can be obtained when the electrode is disposed at the both ends, and the electrode is disposed around the eye. When the part is on, for example, the forehead, the temple, etc., the EOG can also be obtained at the same time.

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, it is also possible to implement that the bent portion is replaceable, In order to replace different shapes, materials, sizes, colors, etc., it is more convenient to use. On the other hand, it can be implemented to replace the two ends, and the executable function can be changed by replacing different circuits. Therefore, there are various possibilities and 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, On the wrist, with the addition of information to provide an interface, the user will be able to easily obtain information when needed, just like watching a watch, so the situation will be used, as shown in Figure 25a, the user will usually The wristwatch/brace with the EEG signal acquisition function is 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-worn brain that can be used anywhere. An electric detecting device, wherein the connected electrode may be in any one of the ear-wearing forms described above, for example, a single ear-wearing structure having two electrodes, or two ear-wearing structures each having an electrode form. According to the actual needs, if a single ear wearing structure including two EEG electrodes is designed, only one connecting line will be needed, in addition to the convenience of use, the complexity is increased. It is also greatly reduced. In addition, when two ear-wearing structures are used, it can be further implemented in the form of two channels of electroencephalogram signals to monitor the activity of the left and right brains. 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, and without limitation, as long as the position and arrangement of the head and/or the auricle are in contact with the frame of the eyeglass structure, it is within the scope of the present invention. Moreover, the position and form of the above-mentioned electrodes are also intended to be illustrative only, and may be substituted and/or combined with each other without limitation.

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 electro-oculogram and the EEG signal are different, the signal processing can be separated from each other. Therefore, in the concept of the present invention, at least two electrodes can be obtained 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 eyeglass structure of the left and right portions, or the circuit can be disposed through the combination of the external module and the temple, which are possible embodiments.

Further, the two electrodes used to obtain the EEG signal can also be implemented as glasses. The structure and the ear-wearing structure are arranged, for example, an ear-wearing structure may be extended from the eyeglass structure, or the eyeglass structure has a connecting port to electrically connect an ear-wearing structure, so that through the eyeglass structure, Choose to contact the V-shaped depression, the back of the auricle, the temple, the bridge of the nose, and/or the area between the eyes, and through the ear-wearing structure, you can choose to contact the V-shaped depression, the back of the auricle, the bottom of the ear, the wall of the ear, the pair The otoscope, the tragus between the tragus, and/or the tragus to jointly acquire 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 invention, the eyeglass structure, the earwear structure, and the electrodes may 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 request and change the settings, there is no limit.

In addition, the earwear 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 connection port 73 to the ear. The mechanical connection and the electrical connection are simultaneously achieved by means of plugging between the wearing structures, and in this embodiment, the electrodes 702 on the ear-wearing structure are 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 structure without lens, 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 additional structure of the electrode 721 is implemented in a dispersed form to facilitate the electrode to pass through the hair to contact the scalp, as for the other Electrodes 702 are disposed on the surface of the ear-wearing structure to contact the ear, whereby the electrode 702 disposed on the ear-wearing structure is regarded as a reference electrode, and the electrode 721 on the additional structure is regarded as a motion detecting electrode. To obtain the EEG signal in 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, and similar to the foregoing case, the user can usually have a wrist-worn structure having an EEG signal capturing function, for example, a watch, a hand. Ring, etc., worn on the wrist, when there is a need to measure the EEG signal, then connect the EEG electrode in the form of glasses, or, usually wear a wrist-worn structure and glasses, and connect the two when there is a measurement demand. As a result, it is also quite convenient and suitable for everyday life. Here, the connected electrodes may be in the form of any of the aforementioned spectacles, without limitation.

In addition, in addition to the electroencephalographic electrodes disposed on the earwear structure and the spectacles structure, the brain activity sensor according to the present invention may also be implemented with other brain electrical electrodes, for example, from an earwear structure or a spectacles structure. Extending an electrode disposed at other positions on the head, for example, an EEG signal that is placed on the forehead to obtain the frontal area, and an EEG signal that is placed on the top of the head to obtain the parietal region, and/ Or the posterior head of the skull can obtain the electroencephalogram signal of the occipital region, and more specifically, when implemented in the form of glasses, the electrode behind the skull can also be extended through the temples, so that There is no limit to the actual demand. In addition, when the electrode is provided with hair, such as the top of the head, the back of the head, etc., you can choose to use a needle electrode, a dispersion electrode, or other electrode form that can pass the hair to obtain a signal, or It is 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, combined for listening. A music earphone, or a headphone microphone for transmitting and receiving sound, and the like, and is not limited to a bilateral earwear or a single-sided earwear form, or an in-ear casing or an earloop form, is suitable for the concept of the present invention, 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. Communicating, in this case, in the case of having a sounding element (air conduction or bone conduction) and a sound pickup 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 ear-wearing and/or eyeglass-type brain activity sensor of the invention 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 is further integrated into 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 to provide a user with a better hearing effect, for example, in two auricles. The inner casing is provided inside, and the music is provided through a wireless connection or a wired connection between the two, for example, divided into left and right channels, so that the music has a stereo effect, and further, it can be implemented as a memory in the earphone. The body can store music and provide playback functions, so that even if you don't communicate with the portable electronic device, you can listen to the music and make it easier to use.

Accordingly, in a preferred embodiment, the single ear-worn brain activity sensing device according to the present invention is implemented to have a wireless transmission module, such as a Bluetooth, to communicate with an external portable electronic device. For example, the obtained physiological signals and information are transmitted to the portable electronic device and then provided to the user. On the other hand, in addition to the physiological signal capturing function, the sounding component and the electrical signal transmission are also provided. To receive signals from the outside, for example, sound Frequency signal, and here, the source of the audio signal has several different options, for example, from another earphone connected to the signal transmission port, for example, in the other ear device The stored audio signal can also be obtained from an external portable electronic device, and can be obtained by wired or wireless means, for example, the other ear-wearing device can be connected to the cable or wirelessly connected to the portable device. After the audio signal is obtained by the electronic device, the audio signal is connected to the electronic signal transmission port, or alternatively, the audio signal is transmitted and wired to the portable electronic device to obtain an audio signal. s Choice.

As for the playing of the audio signal, it is performed by an audio control circuit located in the other ear-wearing device, wherein the audio control circuit can be realized through the electrical connection between the two ear-wearing devices. The sounding element is driven to perform audio playback, and further, when the other earwear device also has a sounding element, 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 ear-wearing devices, it is advantageous that the connection between the two ear-wearing devices can be implemented as a removable form, so that an example is given. In other words, when the user only needs to perform physiological signal detection, the other ear wearing device can be removed, and when there is a need to listen to music, it is only necessary to connect the other ear device (and connect to the portable device). The electronic device can be used conveniently, and the other ear-wearing device can also be used alone to provide a single-ear music playing function. Further, if the other ear-wearing device is also provided with a sound collecting component, the The other ear-wearing device can also be used as the earphone microphone of the portable electronic device. In addition, the other ear-ear device can also be implemented as an electrode, and the brain-electric signal can be simultaneously captured by the two-side ear-wearing device. There is also no limitation, and 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. There is no limitation on the connecting line of the wearing device, or the wearing structure which can be set on the neck or the head as described above.

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 a further aspect, 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. 26a, a connection structure 80 is embodied to protrude downwardly from the in-ear housing. In addition, and FIG. 26b 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. 26c, and various options are available depending on 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 for acquiring an EEG signal. For example, Figure 26b shows that the electrode 82 is directly connected to the connection structure 80 to contact the pinna. The back side, and the 26th figure, show that the electrode 82 is disposed on an external member 84 to contact the V-shaped region. In this case, the EEG signal can be obtained by simply matching the other electrode on the in-ear housing. Alternatively, it may be implemented to connect the electrode to the connection structure through the connection line and to be disposed at other positions, for example, another ear, a head, etc., and there are many options for setting the medium, for example, another ear wearing structure, The structure of the glasses, the head-mounted structure, or the electrode patch are all feasible, and there is no limitation. When being placed at other positions on the head, it is advantageous to increase the sampling position for obtaining the EEG signal. Helps to obtain brain signals from 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, directly connecting the electrode or passing through a carrier A carrier electrode or the like is 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 a sounding element on another ear-wearing structure to achieve stereo effect in the case of having a sounding element, There are various possibilities; in addition, as described above, the position and the protruding direction of the connecting structure can also 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, the brain activity sensor according to the present invention may include other physiological sensing elements or electrodes in addition to detecting brain electrical signals to obtain other physiological signals.

For example, there may be at least one pair of light-emitting elements and light-receiving elements, where the light-emitting elements and the light-receiving elements refer to sensing elements that use the principle of PPG (photoplethysmography) to obtain optical signals, for example, by means of penetration Or the measurement method is performed to obtain the blood physiological information of the user, so that other physiological information can be further analyzed, for example, information on changes in blood oxygen concentration can be obtained, and the heart rate of the user can be known by obtaining continuous pulse change. Sequences for related analysis, so the scope of application is quite wide and unlimited.

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 The position of the trace, for example, Fig. 21 shows a case where 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 ear canal portion, and therefore, as long as the part entering the ear canal After the setting is completed and the position of the tragus is aligned, the blood physiological information can be naturally obtained from the position of the tragus. In these cases, the inner casing of the ear further provides a light-shielding effect, which is more favorable for obtaining high-quality signals. Moreover, it is quite convenient to complete the setting of the electrode and the light emitting element and the light receiving element in one wearing action.

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 spectacles structure is in contact with the skull and the ear, for example, the bridge of the nose, the area between the eyes, the temples, the auricle, and the area around the auricle. And so on, without limitation, 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 auricle back, and/or the head near the auricle, for example, The temples, even, can also be implemented in the form of electrodes 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 included to obtain an electrocardiogram signal, for example, at least one a first electrocardiographic electrode and a second electrocardiographic electrode, wherein the first electrocardiographic electrode can be implemented to be in a position with the user when the brain activity sensor according to the present invention is worn on the user a surface that contacts the skin of the skull or the skull, for example, when implemented in an ear-wearing form, the position of the extension member contacting the V-shaped depression, the back of the auricle or the skull, the position of the inner casing of the ear contacting the inner surface of the auricle, or When implemented in the form of glasses, the temples contact the V-shaped depression, the temple, the back of the auricle, the position of the skull skin near the auricle, the nose bridge, the mountain root, and the two-eye area of the nose pad.

As for the second electrocardiographic electrode, there are various implementation options, for example, an exposed surface of the ear-wearing structure or the eyeglass structure (or additional structure) for allowing the user to touch through the hand, that is, The user can instantly obtain the ECG signal by raising the hand touch when the measurement is needed, which is convenient. Here, the exposed electrode can be made of metal, conductive rubber, or any conductive material, without limitation, and further Further, it can be implemented as a non-contact type electrode, for example, a capacitive electrode, an inductive electrode, or an electromagnetic electrode, etc., to increase ease of use; in addition, the electrode can be extended through the connecting wire to be set in other Position, for example, neck, shoulder, chest, upper arm, wrist, finger, etc., 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 , arm-worn structure, wrist-worn structure, finger-worn structure, etc., or implemented as a patch form, etc., all contribute to electrode fixation, and the advantage of this method is that due to two electric They are all fixed on the wearer, so they can obtain a continuous ECG signal. As long as the memory is set up, the user's heart activity can be recorded for a long time. It is very helpful for the doctor to diagnose. Here, it should be noted that Even if the electrocardiographic electrode is configured through the wearing structure, the ECG signal can be extracted as needed, and the user can select the usage mode according to actual needs.

Wherein, when implemented in the form as shown in Figures 24a-24c, the first electrocardiographic electrode is equally The second electrocardiographic electrode can be disposed on the wearable structure at a position where the hand can be contacted by the hand, and can be implemented by the hand when being worn on the neck, and can also be implemented. In order to be contacted by the hand when wearing the head, the ECG signal can be obtained, and the same can also be extended through the connecting line without limitation.

In addition, it should be noted that both ears are selectable 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 has a considerable influence on the signal quality, wherein 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 that obtained by contacting the right upper limb, especially if the electrode is in contact with the left ear and the left upper limb respectively. The quality of the signal, 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 poor signal quality due to contact with the right upper limb, thereby causing analysis. Misjudgment.

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 a heart The electric electrode, at this time, 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, that is, the so-called Pulse Transit Time (PTT), and PTT is related to the arterial stiffness that affects blood pressure, so the reference blood pressure value can be calculated by a specific relationship between PTT and blood pressure values.

Moreover, when the ECG signal is obtained by touching the second electrocardiographic electrode on the exposed surface with the hand, thereby obtaining the PTT, since the hand needs to lift the contact exposed electrode, in this case, regardless of the light emitting element and the light The detection position of the receiving component is the inner or back side of the auricle, the skull skin near the auricle, the bridge of the nose/mountain/two eye points, or the hand touching the exposed electrode, and the relative height between the heart and the heart is unchanged. According to hemodynamics, PTT is affected by the difference in height between the measurement position and the heart position. Therefore, in this way, the general PPT measurement is usually caused by the influence of the sampling position relative to the unfixed heart. It is excluded, so that as long as the calibration is performed, the accurate blood pressure value can be stably obtained, and such a measurement method is not affected by the standing posture or the 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. Relaxed and interrupted consciousness, therefore, by increasing the beta wave phase For the purpose of increasing the concentration of the θ wave, for example, one of the methods for treating patients with ADHD (Attention deficit hyperactivity disorder) is to observe the θ wave/β wave through neurophysiological feedback. In addition to observing the ratio of theta wave to the beta wave, the slow cortical potential (SCP) is also a brain activity often observed in the neurophysiological feedback of concentration, in which the negative shift of the SCP (negative shift) is related to more concentrated attention, and the positive shift of the SCP is related to reduced attention. Of course, it can also detect brain waves in other frequency ranges, for example, gamma waves. The appearance of 28-40 Hz) represents a highly focused state, etc. In addition, there are other types of applications, for example, for monitoring the occurrence of epilepsy as a basis for diagnosis/diagnosis, and therefore, there is no limitation.

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 invention has both a light-emitting element and a light-receiving element and/or an electrocardiographic electrode, and the heart rate sequence obtained by the analysis can be obtained through the HRV to obtain an autonomous nerve activity situation, 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; Or, you can also inform the user of the current brainwave state by the level of the sound frequency or by voice. The physiological state represented, etc.; or alternatively, vibration can be generated through the portion in contact with the skin, for example, the speed and the slowness of the vibration frequency represent relaxation and tension; or, the visual feedback can be provided through the glasses. Therefore, visual, audible, and/or tactile sensing signals can be generated through the ear-wearing structure or the spectacles structure, and there are various possibilities and no limitations.

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, because increasing the amplitude of the RSA helps trigger the Relaxation Response, relieving the cumulative pressure, and increasing the proportion of parasympathetic/sympathetic activity. The effect is therefore, by observing the user's heart rate change mode, and when the heart rate starts to accelerate, the user is informed by the guide that the inhalation can be started, and when the heart rate starts to slow down, the user is informed through the guide that the exhalation can be started. Achieving the effect of increasing the amplitude of the RSA, which is the coherence between breathing and heart rate, also helps to achieve 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. Calculate the reference blood pressure value by the relationship between PTT and blood pressure, or further use PPT as a raw Feedback information. Therefore, it is a relatively advantageous embodiment to obtain a variety of physiological information by simply wearing a wrist-worn structure and an ear-wearing structure, and it is easy to operate.

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-electric signal, can obtain information such as the number of blinks and the speed of the user, and can also analyze the degree of waking, drowsiness, or fatigue of the user, plus the brain activity of the present invention. 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 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 signals can provide sleep onset and sleep offset, molars and REM information, heart The electrical signal can be used to assist in observing the physiological state during sleep, for example, the state of the autonomic nerve, the condition of the heart activity, etc., and the electrical activity of the skin can provide information about the sleep stage. Further, if further, the light-emitting element and the light are added. Receiving elements, blood oxygen concentration can be obtained to determine the occurrence of hypopnea, and/or additional motion sensing elements, such as Accelerometer, G sensor, Gyroscope ), a magnetic sensor, etc., can provide information on body movement, and / or set a microphone to detect the situation of snoring. 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. First, according to the position of the motion detecting electrode of the present invention, it is known that the measured brain electrical signal of the cerebral cortex and temporal region adjacent to the auricle is particularly suitable for detecting the cerebral cortical function of 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 reaction (the magnitude of the amplitude of the generated brain waves), the adaptability (using continuous sound stimulation), etc., and by reflecting the structural characteristics of the sensor of the present invention, the respective responses of the left and right temporal lobe regions are also 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), improve mental capacity and performance (Mental Capability and Performance), for example To treat depression, change the state of the brain, for example, Dementia, changes the cognitive state, changes / induces sleep and other effects.

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), And other known electrical stimuli, etc., wherein common forms of tCS include tDCS (transcranial Direct Current Stimulation), tACS (transcranial Alternating Current Stimulation), and tRNS (transcranial Random Noise Stimulation), and in particular, because transcranial electrical stimulation (current application range is usually less than 2 milliamperes) is applied to the local physiological tissue above the cerebral cortex, thereby affecting the corresponding brain The activity of the cortex, 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) correspond to In charge of 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 the advanced cognitive functions, such as language and self-awareness, are mainly from the frontal lobe area. In charge, therefore, by placing the electrodes on the skull corresponding to different cerebral cortical regions, in addition to the activity of the relative cortical regions, the cerebral cortex of the region can be affected by the manner 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 location is used for stimulation, for example, trigeminal, vagus, sympathetic, cerebral cortex, etc., as well as common Symptoms such as shoulder and neck muscle soreness, all located near the head and neck, just adjacent to the position of the wearing structure used in this case, for example, ear-wearing structure, eyeglass structure, neck-wearing structure, and/or head-mounted structure Contact position, for example, earlobe, auricle, ear canal, behind the ear, neck, near the temple, forehead, apex, posterior cranial, etc., for example, many branches of the trigeminal nerve, for example, auriculotemporal nerve Located near and above the ear, the supraorbital nerve, the supratrochlear artery nerve, and the ophthalmic nerve are located near the eyelids and forehead, and these are just glasses structures/glasses. The structure is worn at the position where the ear/head is in contact with each other. Therefore, it is quite suitable to be implemented by using the existing structure; in addition, the effect of improving the physiological state can be achieved by electrically activating the acupuncture points.

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; Two wearable structures are used, for example, the ear-wearing structure is matched with the head-wearing 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 wear 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 performing. Electrical stimulation, for example, may be performed by extending only one electrode and performing electrical stimulation with one of the electrodes on the wearing structure, or extending two electrodes and performing electrical stimulation through the two extended electrodes. In the form of an extended electrode, it is advantageous that the position of the selectable contact becomes more extensive and is not limited to the position at which the wear structure is placed, for example, as shown in Fig. 27a, which can be made of glasses The temple extends beyond the neck to contact the back of the neck, behind the ear, forehead, etc., as shown in Figure 27b-27c, 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. The structure or the neck-wearing structure can also increase the contact position at which the electrical stimulation can be performed by using the extension electrode. Therefore, various possibilities are possible, and it should be noted that it can be implemented to extend only one electrode, or can be implemented as 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 an attachment element, for example, a patch as shown in the figure, or the attachment element can be another wearable structure, for example, extended by the structure of the eyeglass. An ear-wearing structure, a neck-wearing structure, an arm-worn structure, a wrist-worn structure, a finger-wearing structure, or the like, or an ear-wearing structure extending out of a spectacles structure, a head-wearing structure, a neck-wearing structure, an arm-worn structure, a wrist-worn structure, Refers to the form of wearing a structure, or the form in which the head/necked structure extends out of the ear-wearing structure, the arm-worn structure, the wrist-worn structure, the finger-wearing structure, etc., all of which are feasible and, alternatively, when implemented as When the two extension electrodes are used, they may be implemented by two extension elements for carrying, or may be implemented by one extension element for carrying two electrodes at the same time, 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, can be used by extension form For wet electrodes, it is also possible to replace the electrodes of the original wearing structure with wet electrodes.

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, a signal is generated by a signal generating unit and transmitted to an electrode connected thereto, thereby causing the electrode to apply electrical stimulation to the user. Therefore, by changing the electrical signal, the electrode is applied to the use. The electrical stimulation of the person 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 this case, it is also possible to use DC power 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 state of brain activity, and the change can be known through the EEG signal. For example, as described above, the alpha wave and the beta can be observed. The proportion of the wave, in order to understand the degree of relaxation and tension of the user, and the multi-channel setting, the activity and energy difference of the left and right brain can be known. Furthermore, the potential difference between the left and right brain can be observed. 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, and duty cycle ( Duty cycle), duration, etc., have an effect on the brain, and then achieve the goal, and can also be used to understand the effect of electrical stimulation after understanding the changes in brain activity after electrical stimulation, and adjust 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-mounted 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 for obtaining the ECG signal, for example, the head. / Ears and upper limbs, two ears, and neck/shoulders and upper limbs, etc. 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 patterns may be provided for the user to freely select, or further implemented to first select a correlation from the set based on the measured physiological state information. After the electrical stimulation mode, the user can select it, or can be implemented to allow the user to adjust the electrical stimulation parameter setting as described above, which is a possible implementation manner, and is not limited.

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, 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 obtains an EEG signal for a specific time through at least two EEG electrodes, and then performs a frequency domain analysis process on the acquired EEG signals through a processing unit, for example, through Fourier transform. Or use a digital filter to obtain the energy distribution of the EEG signal, and then in different brainwave frequency bands, for example, δ band (0.1-3 Hz), θ band (4-7 Hz), slow α Frequency band (8-9 Hz), intermediate 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 In the beta band (20.5-28 Hz), or in other bands, one or several peak energies during that time can be observed, for example, an energy peak of 8 Hz in the alpha band, or 8 Hertz and 10 Hz energy peaks, and after selecting a frequency range, for example, selecting an alpha band or a self-defined range of frequencies, a stimulus signal generating unit can be based on the frequency of the energy peak in the band. Produce a physiological stimulus signal To the user.

Here, it should be noted that the specific time may be implemented as an instant, for example, the frequency domain analysis process may be performed once every second or less, or may be taken for a longer period of time, for example, 5 Minutes or longer, and then perform long-term segmentation to perform frequency domain analysis processing, then take the average value, or directly perform frequency domain analysis processing for the whole period of time, which is a possible way, which can be changed according to actual needs. There are no restrictions.

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 present invention, and is not limited, and 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 changes accordingly, such as In this way, 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 placed on the earwear structure that extends from the spectacles structure, For example, two ear-wearing structures may be extended from the single-sided temple, or an ear-wearing structure may be respectively extended from the two-legged legs to be disposed on the two ears, which may 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, two or more stimuli can be applied simultaneously, for example, with the addition of visual stimuli and auditory stimuli, or simultaneous application of electrical stimuli and auditory stimuli, or to different cerebral cortical regions. Simultaneous execution of electrical stimulation is an optional execution mode. In addition, the second stimulation source 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, a plurality of The frequency of stimulation can be the same or different, there is no limit, and only need to have a frequency proportional relationship with the energy peak.

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, in the same way, whether it is the type of resonance physiological stimulus applied, or The mode of the line, parameter setting, etc. can also be implemented by the user to select, for example, an input operation interface provided by the ear wearing structure and the eyeglass structure, for example, a button, a touch interface, a light sensor, a voice control, etc., or It is an external device that communicates with the ear-wearing structure/glasses structure, for example, an operation interface of a mobile phone or a wrist-worn device, and the physiological state change caused by applying a resonant physiological stimulus can also be set by wearing the ear. The information providing unit on the structure/glass structure or the external device that communicates with the earwear structure/glass structure is provided to the user, for example, through visual, auditory, tactile, etc., to help the user to understand more His current physiological state also contributes to the achievement of brain wave resonance.

In a particular embodiment, as shown in Figures 28a-28b, 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. Electrode In addition to obtaining EEG signals, it 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 earwear. 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; And further, it can be increased Other physiological sensing components are provided to obtain other physiological signals. For example, a blood sensor can be used to obtain blood physiological signals, thereby obtaining information such as heart rate, respiration, blood oxygen concentration, etc., and other electrodes can be set to obtain an eye. Physical signals such as electrical signals, myoelectric signals, and skin electrical signals, or the addition of a microphone to learn about breathing, snoring, and Sleep Apnea events, all of which help to understand sleep more in detail. Conditions, and in addition to being used to adjust physiological stimuli, physiological signals can also be recorded 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 Allow the stimulus to be performed in the most effective way. For example, if you are observing brain waves, you can observe whether the energy distribution in a specific frequency band is stable for a period of time or between multiple segmentation times, or Whether the energy peaks are consistent, etc. If the heart rate is observed, it can be observed whether the heartbeat frequency, the respiratory rate, the heartbeat variability, the coherence between the heart rate and the breathing 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. A device based on whether it is used to obtain a physiological signal or to perform a stimulus is also within the scope of the present invention.

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 invention is in the form of earwear or glasses, it is also suitable Used in combination as a human-machine interface, and in the case where the detected physiological signals include EEG signals and heart rate sequences, there are several possible ways in which instructions can be generated, for example, but not limited to, due to brain waves. The proportion of alpha 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, this can be used as a basis for generating instructions. When the EEG electrode can detect the action of the eye and obtain the EOG, the command can be issued by, for example, blinking, moving/turning the eyeball, etc. a physiological activity controlled, and as mentioned above, breathing not only affects the heart rate (ie, the so-called RSA), but also causes fluctuations in the brain waves in the low frequency segment, and thus, under the framework of the present invention Whether the brain wave signal is detected or the heart rate sequence is detected, the user's breathing behavior pattern can be changed to be used as a basis for generating instructions, for example, the user can intentionally lengthen the period of inhalation. Orders, etc., or you can increase the heartbeat variability by deepening the breathing, thereby increasing the RSA amplitude, as a basis for issuing instructions, and other physiological signals can also be used as command basis, for example, myoelectric The number (EMG) can distinguish whether the muscles are contracted or not, and the instructions can be given by the force of the left and right teeth respectively. Therefore, there are various possibilities and no restrictions.

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 in contact with the novel brain electrical signal sampling position, that is, the ear wall, the tragus, the tragus, the tragus, the tragus, The back of the auricle, and/or the position of the auricle and the V-shaped depression between the skulls, can provide a stable electrode force parallel to the bottom of the ear, which is different from the conventional technique, and can be contacted through the wearing action without additional structure. Providing force to naturally achieve stable contact is quite helpful for obtaining high quality EEG signals.

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. It makes the use more convenient, and the effect of performing stimulation is more effective and significant because of the detection of physiological signals.
