<Wireless power transmission ‧Wireless communication method>

FIG. 6 and FIG. 7 are explanatory diagrams of a mask-type wearable device as a skin moisture amount measuring device attached to a mask by wireless power transmission and wireless data communication. Specifically, FIG. 6 is an example of a skin moisture amount measuring device using wireless power transmission and wireless data communication in the electromagnetic induction mode, and FIG. 7 is a modification 2 of the first embodiment. An example of a skin moisture measuring device using microwave power wireless transmission and wireless data communication.

In FIGS. 6 and 7, a portion directly attached to the mask 10 together with the electrodes 61 and 62 is referred to as a mask wearing portion 600 (600A).

In the configuration of FIG. 6, the difference from the configuration of FIG. 3 is that, in order to wirelessly connect the power source 821 to the electrodes 61, 62, the skin moisture amount measuring device 15A (15B) is provided with a configuration for wireless power transmission. Elements and components used for wireless communication of data.

Specifically, in FIG. 6, the wireless power transmission unit of the electromagnetic induction system is provided with a power transmission coil 881 on the skin moisture amount measuring unit 800 side and a power receiving coil 631 on the side of the mask wearing unit 600. Further, as the wireless communication unit for transmitting and receiving data, the wireless transmitting unit 620 is provided on the side of the mask wearing unit 600, and the wireless receiving unit 89 is provided on the side of the skin moisture measuring unit 800.

As the wireless communication method, Bluetooth (registered trademark) and a one-to-one wireless LAN can be used, and communication in a dedicated frequency band can be set.

According to this configuration, in the skin moisture amount measuring unit 800, electric power is supplied from the power source 821 to the power transmitting coil 881, and the power transmitting coil 881 is brought close to the power receiving coil 631 to generate a magnetic flux for short-distance transmission. Therefore, it is necessary to measure the time. The skin moisture amount measuring unit 800 is brought close to the mask wearing portion 600 disposed on the mask 10.

Due to the magnetic flux generated by the approach, a current flows in the power receiving coil 631, and a current is applied to the electrodes 61, 62. At this time, in the mask wearing unit 600, the applied electric power (for example, the current value generated by the ammeter 640 and generated by the magnetic flux) and the measured value after the current is applied to the electrodes 61 and 62 are temporarily stored in the measured value. In the temporary storage unit 610, the data of the measured value is transmitted by the wireless transmitting unit 620.

Further, in the skin moisture amount measuring unit 800, the wireless receiving unit 89 receives the transmitted data, and the measuring unit 81 calculates a resistance value (measured value) based on the applied electric power. The measurement value storage unit 83 stores the measurement result and the environmental information ‧ the subject information measured by the environmental information ‧ the subject information measurement unit 85 in the measurement time. The display unit 86 displays the measurement result and the environmental information and the subject information for each measurement time.

According to this configuration, the skin moisture amount measuring unit 800 approaches the mask 10 at the measurement time of the skin moisture amount, and wireless power transmission and wireless communication can be performed even if no power is supplied to the mask wearing portion 600 side.

Fig. 7 is a configuration diagram of a skin moisture amount measuring device in the form of microwave wireless transmission. In the microwave power system, a microwave generating unit 882 is provided on the skin moisture amount measuring unit 800A side, and an antenna 632 and a rectifying circuit 633 are provided on the mask wearing unit 600A side. The antenna 632 and the rectifier circuit 633 provided on the mask wearing portion 600A side function as so-called rectennas.

In this configuration, the skin moisture amount measuring unit 800A transmits the microwave generated by the microwave generating unit 882. In the mask wearing unit 600A, the antenna 632 receives the microwave, and the rectifying circuit 633 rectifies the received microwave wave to obtain electric power.

Here, in order to reduce the size of the mask wearing portion 600A, the antenna attached to the mask 10 is, for example, a thin film antenna, and the rectifier circuit may be a system-LSI (large-scale integrated circuit) such as a CMOS (Complementary MOS) rectifying chip. .

In the same manner as in FIG. 6, the electric power acquired in the mask wearing portion 600A (for example, a value obtained by measuring the electric current rectified by the ammeter 640) and the measured value after the voltage is applied to the electrodes 61 and 72 are The temporary memory is stored in the measured value temporary storage unit 610, and the data of the applied power value and the measured value is transmitted by the wireless transmitting unit 620.

Then, in the skin moisture amount measuring unit 800A, the wireless receiving unit 89 receives the detected detection result, and the measuring unit 81 calculates the resistance value (measured value) based on the applied electric power. The measurement value storage unit 83 stores the measurement result in association with the environmental information and the subject information of the measurement time, and displays the measurement result and the like on the display unit 86.

In this configuration, no power is supplied to the mask wearing portion 600A side, and wireless power transmission and wireless communication can be performed even if the skin moisture amount measuring unit 800A does not approach the mask 10 during the measurement time. However, since the conversion efficiency of the microwave transmission is low, in order to increase the output of the microwave generating unit, it is necessary to generate a large amount of electric power in the power source on the skin moisture amount measuring unit side, and the power supply is also increased in size as the electric power is increased. . Therefore, it is preferable to appropriately select the structure of the skin moisture amount measuring device based on the desired size and utilization form of the skin moisture amount measurement unit side.

It is to be noted that FIGS. 6 and 7 show an example in which only the electrode of FIG. 3 and the wireless power transmission structure are provided in the mask wearing portion, and the power supply is also provided in the mask wearing portion. The configuration related to wireless transmission of power is set to achieve wirelessization of the device.

<Wireless communication method>

8 is an example of a skin moisture amount measuring device of a wireless data communication system in which a power source is provided in a mask wearing portion in a third modification of the first embodiment. In the configuration shown in FIG. 8, the power source 650 and the timing element 660 are provided on the side of the mask wearing portion 600B as compared with FIGS. 6 and 7, and therefore, the skin moisture amount measuring device 15C is not provided for the slave.

In addition, in the case where the environmental information ‧ the subject information measuring unit 85 is provided on the skin moisture amount unit 800 side, the environmental information ‧ the subject information measuring unit may be provided in the mask wearing unit 600B side. Further, an acceleration sensor or the like for detecting the face motion of the subject may be provided in the mask wearing portion 600B.

In the present configuration, similarly to FIG. 3, the power supply 650 applies electric power to the electrodes 61, 62 at regular time intervals based on the time measured by the timing element 660.

In the mask wearing unit 600B, the measured electric power and the measured value after the electric power is applied to the electrodes 61 and 62 are temporarily stored in the measured value temporary storage unit 610, and the data of the measured value is transmitted by the wireless transmitting unit 620.

Then, the skin moisture amount measuring unit 800B receives the detection result transmitted by the wireless receiving unit 89, and the measuring unit 81 calculates the resistance value (measured value) based on the applied electric power. The measurement value storage unit 83 stores the measurement result in association with the environmental information of the measurement time and the subject, and displays the measurement result and the like on the display unit 86.

In this configuration, the configuration for the wireless transmission is not required, and the space measurement unit 81, the measurement value storage unit 83, the display unit 86, and the like are provided on the skin moisture amount measurement unit 800B side. According to this configuration, it is possible to achieve further miniaturization of the mask wearing portion 600B while achieving wirelessization of the skin moisture amount measuring device 15C.

In the example shown in FIGS. 6 to 8 described above, since there is no wire, the skin moisture amount measuring unit 800 (800A, 800B) can be moved away from the mask 10 without considering the length of the wire. At this time, at least when performing wireless transmission of power and wireless transmission of measurement data, it is preferable to provide the skin moisture amount measuring unit 800 (800A, 800B) within a range in which the wireless signal emitted from the mask 10 can be reached.

Further, in the example shown in FIGS. 6 to 8, since there is no wire, no foreign matter enters the field of view of the subject even during measurement, and the psychological burden on the subject can be further reduced.

Further, in these configurations, since the display unit is provided in the skin moisture amount measuring unit, the subject can wirelessly confirm the detection state on the display unit at any time.

It is worth mentioning that, in the case of wirelessly implementing power transmission and data communication, the mask wearing portions 600, 600A, 600B may be integrated with the mask 10, or may be detachable with respect to the mask 10. .

<<Executive example 1>>

The inventors of the present invention confirmed the fluctuation in the amount of skin moisture by using the skin moisture amount measuring device attached to the mask described in the first embodiment and a commercially available skin moisture amount measuring device (measuring device).

The amount of moisture in the skin changes with the environment of temperature and humidity. Therefore, an experiment for measuring the amount of fluctuation in the amount of moisture on the cheek skin was carried out using the skin moisture amount measuring device and the measuring device attached to the mask according to the first embodiment under the condition that the environment was changed.

As a measuring device of this embodiment, an impedance type SKICON (registered trademark) is used. Using SKICON, each time the amount of skin moisture is measured, the probe attached to the main body of the measuring machine is brought into contact with the skin to obtain a measured value.

FIG. 9 is a graph comparing the measurement results of the skin moisture amount measuring device attached to the mask according to the first embodiment and the measurement results of the SKICON. The experiment was performed on one subject (n = 1).

As shown in Fig. 9, SKICON shows that the amount of moisture in the skin increases when the temperature is raised and the humidity is increased, and the amount of moisture in the skin tends to decrease when the temperature is lowered and the humidity is lowered. Relative to the detection results of the SKICON, the mask tester also showed a tendency to be the same.

In addition, the noise portion in the test result of the test machine corresponds to the time when the facial expression changes due to moving body, speech, sneezing, coughing, and the like.

As described above, by using the skin moisture amount measuring device according to the first embodiment of the present invention, it is possible to detect a change in the amount of keratinous moisture that changes with temperature, similarly to a commercially available measuring device.

Further, in the present embodiment, since the electrodes 61 and 62 are provided in the ear hook portion 102 of the mask 10, the mouth of the subject 91 that is in contact with the mask body 101 hardly affects the mouth. Further, in the earloop portion 102, the electrodes 61 and 62 provided in the earloop portion 102 have gas permeability, and the flexible conductive cloth is in contact with the skin. Therefore, the skin shielding effect with the skin is hardly caused. influences.

According to the above results, the skin moisture amount measuring device provided in the mask of the present embodiment does not need to be measured by the probe when performing measurement as in a commercially available measuring device, and is more convenient, and the subject only needs to wear a mask. The amount of skin moisture can be continuously measured at regular intervals, which can reduce the measurement burden of the subject.

In the first embodiment described above, the cheek as the evaluation target portion was directly measured. Further, it is also possible to measure a portion other than the cheek by attaching a measuring device (measuring device) to an ornament other than the mask, and estimate the amount of skin moisture in the cheek portion based on the measurement result. Hereinafter, an embodiment in which estimation is performed based on other parts will be described.

In addition, the resistance value of the skin surface of the first portion such as the nose or the wrist which is the object to be measured and which is in contact with the electrode (see FIGS. 12, 15 and 16) can be used as a direct index of the amount of skin moisture.

Here, in the present embodiment, as a method of evaluating the second portion using the measurement result of the first portion, specifically, the calculation method described below can be performed.

(1) Based on the electrical characteristic value of the skin surface of the first site, the electrical property value of the skin surface of the second site is derived based on the correlation, and the skin moisture score (measured value such as SKICON) of the second site is derived.

(2) Based on the electrical characteristic value of the skin surface of the first site, the water content amount (measured value such as SKICON) of the skin surface of the second site is converted into a correlation.

(3) The correlation relationship is grasped in advance, and the electrical characteristic value of the skin surface of the first portion is directly used as an index of the skin moisture amount.

Therefore, as described above, in order to estimate the amount of skin moisture based on different parts, in detail, the second part (cheek) is estimated by converting the skin moisture amount (resistance value) of the first part (nose or wrist). The amount of skin moisture (resistance value), regardless of the calculation used, must be determined in advance. The details will be described below with reference to FIGS. 17 to 21 .

<Modification 1 of the eyeglass type wearable device>

FIG. 14 is a general view of a wearing type or integrated type eyeglass type wearable device 2A having the skin moisture amount measuring device 11A and the eyeglasses 3 in the first modification of the second embodiment. In the present modification, the outer casing 21A including at least one of the constituent elements included in the skin moisture amount processing unit 20A shown in FIG. 14 is attached to the temple 305 of the eyeglasses 3. Similarly to FIG. 11, the skin moisture amount processing unit 20A is connected to the electrodes 201 and 202 provided on the nose pad 301 by the wire 203A.

Further, as shown in FIG. 14, in the eyeglass type wearable device 2A, an acceleration sensor 204 for detecting the motion of the face and the body of the subject 91 may be provided on the temple 305 of the eyeglass 3, which is attached to the skin. The moisture content processing unit 20A is connected by wire (for example, wire 203B) or wirelessly.

It is worth mentioning that even in the case where the skin moisture amount processing unit 20 can be moved within the range of the wire 203 as shown in FIG. 11, it is preferable to provide the acceleration sensor 204 at the temple 305 to enable Detect the movement of the face. In this case, the measured value/evaluation value storage unit 25b also performs a corresponding memory on the known result of the acceleration sensor 204.

For example, when the face is moved quickly, the electrodes 201 and 202 provided on the nose pad 301 are in short contact with the surface of the nose skin. If the resistance value of the surface of the nose skin is detected at this time, an appropriate value is not displayed. In view of this, the noise caused by the movement of the face of the subject 91 detected by the acceleration sensor 204 can be removed from the measurement result, and the acceleration state can be adjusted when the measurement time is detected at a certain interval. The measurement time is detected to perform measurement after the face movement is stopped.

In addition, the configuration of the skin moisture amount measuring device 11 (11A) shown in FIG. 11 and FIG. 14 shows the power source 22, the measuring unit 23, the calculation unit 24, the correlation storage unit 25a, the measured value/evaluation value storage unit 25b, and the like. All of them are provided in one skin moisture amount processing unit 20A, and the power source 22, the measuring unit 23, and the calculation unit 24 may be provided at other positions.

Further, as shown in FIG. 14, in the case where the skin moisture amount measuring device 11A is attached to the temple 305, it is more preferable to provide the skin moisture amount measuring unit 20B shown in FIGS. 27 and 29 which can be further miniaturized, Instead of the skin moisture amount processing unit 20A shown in FIG.

For example, the power source 22, the measuring unit 23, and the calculation unit 24 (microcomputer) can be attached to the right and left ear hook portions of the temple 305 of the eyeglasses 3, respectively. Thereby, it is possible to avoid concentration of components, and in the case where the constituent elements are respectively provided on the temple 305, the wearability of the glasses or the glasses-type wearable device for mounting the skin moisture amount measuring device can be improved.

In any of the glasses-type wearable devices, the resistance value of the skin surface of the nose is automatically measured for each predetermined time in a state in which the subject wears the eyeglass-type wearable device, and the resistance value of the skin surface of the cheek is estimated. . Thereby, it is not necessary to use a measuring device that can be worn on the body, such as a measurement at a specific position or a hand-held skin moisture meter, to measure the temporal change in the amount of skin moisture for each specific time. Therefore, by releasing the limitation of the position of the subject, it is possible to reduce the burden on the subject who continuously measures the amount of skin moisture.

Further, since the device to be measured is a wearable or integrated type of eyeglass type wearable device, it is possible to avoid the influence of the subject's nervous sweating when performing measurement using a measuring device set at a predetermined position, thereby enabling A history of detecting the resistance value of the skin surface in daily life in a natural state. Therefore, it is possible to grasp the state of the skin surface which is not affected by the tension.

<Composition of a nose pad in an integrated type of eyeglass type wearable device>

15 is an example of a wearable device of the present embodiment, and shows a configuration example of a nose pad integrally formed with an electrode in an integrated type eyeglass type wearable device.

In general, the nose pad portion supports the eyeglasses and has high adhesion to the skin. When the eyeglass-type wearable device is worn for a long time, the skin in contact with the nose pad is always covered, and thus sweating or the like may affect the measured value.

Therefore, in the integrated type eyeglass type wearable device, the nose pad and the electrode are integrated, and it is preferable to form the nose pad by using a shape or material whose electrode is not easily affected by sweating or the like.

In Fig. 15, the nose pad 301A and the electrodes 201A, 202A of (a) are of a structure made of titanium. By using titanium, lightweight, and metal-allergic constitutions are less prone to allergic reactions.

(b) of FIG. 15 shows an example in which the hollow pads (cut portions) 201h and 202h are formed in the nose pad 301B and the electrodes 201B and 202B on which the electrodes are provided.

Since the hollow portions 201h and 202h are provided, it is possible to prevent the skin directly under the electrodes 201B and 202B from being blocked. Further, by reducing the contact area, it is less likely to be affected by dirt or sweat during measurement, and the resistance value (skin moisture amount) of the skin surface can be more accurately measured.

[Third Embodiment: Bracelet Type Wearable Device]

Fig. 16 is an explanatory view showing a wearable device comprising a bracelet type (wrist strap type) wearable device according to a third embodiment of the present invention. In Fig. 16, (a) shows an external view of the integrated bracelet type wearable device 4 in front of the face facing the back of the hand when wearing, and (b) shows the integrated type bracelet wearable in front of the face facing the palm. An external view of the device 4.

In the present embodiment, in the case where the wristband-type wearable device 4 constitutes a wearable device, the electrodes 211 and 212 and the skin moisture amount processing unit 20 are also provided. Alternatively, the electrodes 211 and 212 and the skin moisture amount measuring unit 20B (see FIGS. 27 and 29) are provided as systems for performing calculation and memory processing on the server 5A side.

In the present embodiment, the electrodes 211, 212 are provided inside the bracelet portion 40 and are in contact with the skin surface of the wrist. The resistance value of the skin surface of the wrist is measured by applying a voltage to the electrodes 211 and 212.

Further, in the wristband-type wearable device 4, an acceleration sensor for detecting the motion of the wrist (wrist) or the body of the subject (see FIG. 14) may be provided.

Here, if the wearable device of the present invention is attached to an animal body, a bracelet type device is preferably used.

In addition, FIG. 16 illustrates an integrated bracelet type wearable device in which the skin moisture amount measuring function and the bracelet are integrated and which can perform skin moisture measurement, and the wearable device can also be in the shape of a wristband. A bracelet type wearable device comprising a skin moisture amount measuring device 12 that can be freely installed is provided on the bracelet 9 of an example of the ornament.

For example, as an example of the shape of the skin moisture amount measuring device 12 detachably attached to the wristwatch as a wearing type wearable device, it may be affixed to the inside of the belt portion so that at least the electrode is in contact with the skin surface. The semi-circular shape is a coin shape that can be attached to the back of the dial.

In the above-described embodiment, an example in which a voltage is applied to an electrode and a current value is calculated by a current detector to detect a current value flowing between the electrodes is used as an electrical characteristic value measured by the wearable device. However, the electrical characteristic value which is an index of the amount of skin moisture measured by the wearable device is not limited to the resistance value.

For example, the electrical characteristic value which is an index of the amount of skin moisture measured by the wearable device may be conductance. For example, the conductance (conductivity, inverse number of resistance) can be detected based on a small alternating current obtained by applying a smaller AC voltage than when the resistance value is measured. At this time, for example, an electrical response can be detected as a voltage using an I/V converter.

Further, the electrical characteristic value which is an index of the amount of skin moisture measured by the wearable device may be an electrostatic capacity (capacitance). For example, the electrostatic capacitance between the two electrodes is measured by detecting the voltage difference between the electrodes by the contact area between the electrodes and the skin in a state in which the skin is sandwiched between the two protruding electrodes and the distance between the electrodes.

<<Implementation example>>

As described in the second embodiment and the third embodiment, in order to estimate the amount of skin moisture in the second portion based on the amount of skin moisture in the first portion, it is necessary to determine the correlation in advance. Therefore, in order to investigate the correlation between the amount of skin moisture in various parts of the body including the nose and the wrist and the amount of skin moisture on the cheeks, the following facts were made.

[Example 2]

The inventors of the present invention investigated the correlation between the amount of skin moisture such as the cheek as an example of the second portion and the nose as an example of the first portion, using a skin moisture amount measuring device (measuring device).

The amount of moisture in the skin changes with the temperature and humidity of the environment. Therefore, the amount of change in the amount of skin moisture of the cheek (second part) and the part other than the cheek (first part) when the environment was changed was tested. In the actual example, the first part is measured by the nose, the earlobe, the back of the ear, and the wrist. 17 to 19 show the results of the actual calculation.

As the measurement device of the actual example 2 and the actual example 3, an impedance type SKICON was used. In SKICON, each time the amount of skin moisture is measured, the probe connected to the main body of the measuring device is brought into contact with the skin to obtain a measured value.

Fig. 17 and Fig. 18 are graphs showing the results of measuring the amount of skin moisture of a plurality of subjects by SKICON when there is a change in temperature and humidity. 17 is a measurement result of the cheek, FIG. 18(a) is a measurement result of the nose (nasal root), FIG. 18(b) is a measurement result of the earlobe, and FIG. 18(c) is a measurement result after the ear, and FIG. 18(d) ) is the result of the measurement of the wrist. As shown in No. 1 to No. 10, the skin moisture amount was measured for 10 subjects.

In general, the higher the temperature, the more the skin moisture tends to be affected by sweating. In the present example, this tendency is also observed. When measured at a temperature of 25 ° C and a humidity of 55% as a whole, the amount of skin moisture when measured at a temperature of 23 ° C and a humidity of 35% is more. However, in the cheek measurement of FIG. 17, the data of the subjects (No. 2 and No. 3) which have different behaviors from the change tendency as a whole, and the phenomenon that the skin resistance is affected by sweating, etc., are excluded. .

Similarly, in the measurement of the nose of Fig. 18 (a), the data of the subjects of No. 3 and No. 4 are excluded, and in the measurement of the earlobe of 18 (b), No. 5 and No. 10 are used. Except for the data of the subject.

As described above, the measurement result of the skin moisture amount when the temperature ‧ humidity fluctuates, in addition to some of the above-described examples with different behaviors, the first part shown in FIGS. 18( a ) to ( d ) The measurement results of the nose, the earlobe, the back of the ear, and the wrist showed the same tendency as the measurement result of the second portion (cheek) shown in FIG. 17, and it was considered to have correlation.

19 is a distribution diagram showing the correlation between the amount of skin moisture of the first part (nose, earlobe, behind the ear, wrist) and the second part (cheek) of each subject measured by SKICON.

In Fig. 19, (a) shows the correlation between the nose and the cheek, (b) shows the correlation between the earlobe and the cheek, (c) shows the correlation between the ear and the cheek, and (d) shows the correlation between the wrist and the cheek.

In addition, in FIG. 19, the horizontal axis represents the measured value of the skin surface of the second site (cheek) of each subject, and the vertical axis represents the measured value of the skin surface of the first site (nose, earlobe, behind the ear, wrist). . R represents a correlation coefficient between the measured value of the skin surface of the first portion and the measured value of the skin surface of the second portion (cheek).

Further, in the measurement results of SKICON, as compared with Figs. 19(a) to 19(d), the correlation coefficient between the nose and the wrist and the cheek was large, and the correlation between the earlobe and the back of the ear and the cheek was low. Therefore, in the second and third embodiments of the present invention, as a wearable device for estimating the electric resistance value (skin moisture amount) of the skin surface of the cheek, a wearing type and an integral type including the skin moisture amount measuring device are used. A spectacle type wearable device, an integral type, and a wearable wristband type wearable device will be described.

[Example 3]

The inventors of the present invention conducted an experiment and investigated the measurement results of the cheeks and the nose when using the skin moisture measuring device (SKICON) and the measurement results of the nose when the nose pad type electrode attached to the eyeglass type device was used. Correlation. Figure 20 shows the actual results.

In the present embodiment, the electrodes 201 and 202 which are mounted on the eyeglass type device, the skin moisture amount measuring device attached to the eyeglasses, or the bracelet type device or the skin moisture amount measuring device attached to the bracelet are used. Direct contact with the skin (cheeks, nose) and 60 seconds of data. Then, the same part was measured with SKICON.

In the present example, the subject was a total of 4 men and women, and the environmental conditions were kept constant at a high temperature ‧ high humidity (25 ° C, 55%).

Fig. 20 is a graph showing the correlation between the electric resistance value of the skin surface of the nose measured by the test machine and the skin moisture amount of the cheek measured by SKICON. The test machine is a device having at least the electrodes 201 and 202 and the skin moisture amount processing unit 20 included in the eyeglass type wearable device shown in Fig. 11 or Fig. 14 and having the same operation.

In the test machine, the electrical conductivity of the predetermined calculation according to SKICON is the same as the amount of skin moisture measured by SKICON. In Fig. 20, a linear approximation straight line is drawn using a measured value measured by SKICON on the cheek and a measured value measured by a test machine on the nose, whereby the correlation can be calculated.

As shown in Fig. 20, the measured value (skin moisture amount) of the cheek measured by SKICON can be estimated from the resistance value of the skin surface of the nose measured by the test machine (wearable device). Thereby, the amount of SKICON measured on the cheek based on the resistance value of the skin surface of the nose can be used as an index of the change in the amount of water on the cheek.

As described above, based on the relationship between FIG. 19 and FIG. 20 described above, the correlation between the resistance value of the skin surface of the nose and the SKICON measurement value (skin moisture amount) of the cheek can be measured in advance, and the wearable device can be used based on the measurement. The resistance value of the skin surface of the nose is converted into the resistance value of the cheek (the amount of skin moisture).

It is worth mentioning that the correlation shown in Fig. 20 is based on the tentative formula of the actual implementation, increasing the number of subjects as a reference, increasing the number of data as a reference, pre-limiting the age of the subject or When sex is measured, a correlation with higher reliability can be obtained.

18 and FIG. 19, according to the same idea as FIG. 20, according to the correlation, in the embodiment of the present invention, it is conceivable that the first part (the earlobe, the back of the ear, the wrist) measured based on the wearable device is used. The SKICON measurement value of the first site (the earlobe, the back of the ear, and the wrist) can be estimated from the resistance value of the skin surface. Further, it is conceivable that the measured value of the second site (cheek) measured by SKICON can be estimated based on the resistance value of the skin surface of the first site (the earlobe, the back of the ear, and the wrist) measured by the test machine. From this, it is conceivable that the resistance value of the skin surface of the first portion (the earlobe, the back of the ear, and the wrist) can be used as an index of the change in the amount of moisture on the cheek.

Thus, referring to Figs. 18 and 19, according to the same idea as Fig. 20, it is understood that the resistance value of the skin surface of the first site (the earlobe, the back of the ear, and the wrist) and the SKICON of the second site (頬) are measured in advance. The correlation between the measured amounts and the resistance value (skin) of the second portion (cheek) can be converted based on the resistance value of the skin surface of the first portion (the earlobe, the back of the ear, the wrist, etc.) measured by the test machine.

[Experimental Example 4]

In the above-described embodiment, an example in which measurement is performed using SKICON as a measuring device has been described. In the present embodiment, a capacitive Corneometer (registered trademark) is used as a measuring device for performing measurement. In the Corneometer, as in the case of SKICON, each time the amount of skin moisture is measured, the probe connected to the main body of the measuring device is brought into contact with the skin to obtain a measured value.

Fig. 21 is a distribution diagram showing the correlation between the second part (nose, earlobe, behind the ear, wrist) and the amount of skin moisture of the first part (cheek) measured by the Corneometer.

In Fig. 21, (a) shows the correlation between the nose and the cheek, (b) shows the correlation between the earlobe and the cheek, (c) shows the correlation between the ear and the cheek, and (d) shows the correlation between the wrist and the cheek. Here, as shown in No. 1 to No. 10, the skin moisture amount was measured for 10 subjects.

Specifically, in FIG. 21, the horizontal axis represents the measured value of the skin surface of the second part (cheek) of each subject, and the vertical axis represents the skin surface of the first part (nose, earlobe, behind the ear, wrist). Measured value (converted value of capacitance). In the measurement by the Corneometer, the measured value of the skin surface indicates an arbitrary value of 0 to 120 (unit: GU (given unit)).

In addition, in FIG. 21, R represents the correlation coefficient of the measured value of the skin surface of the 1st site with respect to the measured value of the skin surface of the 2nd site (cheek).

As shown in Fig. 21, it was found that there was a correlation between the first portion and the second portion as a result of measurement using a Corneometer having a capacitance as an electrical characteristic value indicating a skin moisture amount index.

In contrast, as shown in FIG. 20, since the test machine has a correlation with the value of the measurement device, the measured value of the cheek measured by the Corneometer can be estimated based on the capacitance (electrostatic capacitance) of the skin surface of the nose measured by the wearable device. (The amount of skin moisture and capacitance conversion). Therefore, the measured amount of the Corneometer (the amount of skin moisture) of the cheek estimated based on the measured capacitance value of the surface of the nose skin can also be used as an indicator of the change in the amount of water on the cheek.

As described above, by referring to the above-described FIG. 21, by measuring the correlation between the capacitance of the surface of the nose skin and the measured value of the surface of the cheek (the amount of skin moisture), the wearable device can be used to convert the cheek based on the measured capacitance of the surface of the nose skin. Capacitance (skin moisture).

The wearable or integrated wearable device including the ornament and the skin moisture amount measuring device has been described above, and these devices can also communicate, and any of these functions can be performed by an external device such as an information processing terminal.

<The overall structure of the system>

Fig. 22 is a schematic overall view showing a skin moisture amount evaluation network system 200 included in the skin moisture amount monitoring system 100 according to the fourth to seventh embodiments of the present invention.

The skin moisture amount evaluation network system 200 includes at least one of the skin moisture amount monitoring system 100, the data collection computer (PC) 6, or the recommended PC 7. The skin moisture assessment network system 200 can also include a display device 8.

As the wearable device, the subject 91 wears, for example, a wearing type or integrated type eyeglass type wearable device 2 (2A) including the eyeglasses 3 and the skin moisture amount measuring device 11 (11A). Here, the present invention is not limited to the example of FIG. 22. As the wearable device, the subject can also wear the mask-type wearable device 1 including the mask 10 and the skin moisture amount measuring device 15, or include the bracelet 9 and the amount of skin moisture.

Further, the wearable or integrated wearable device 2 (2A, 4, 1) transmits the measured measurement value (resistance value between two points) or an evaluation value calculated based on the measured value to the server 5 . The server 5 accumulates and memorizes at least one of the measured value and the evaluation value. Details of the measured value and the evaluation value will be described with reference to FIG. 23 .

Alternatively, it is recommended that the PC 7 itself can be pre-built with a skin moisture amount evaluation program to display an evaluation index of the skin moisture amount, and set the method of evaluating the skin based on the measurement result of the change in the time of the sputum.

As an effect confirmation and/or an analysis for suggestion, the index for evaluating the amount of skin moisture is the value and amount of change in the amount of skin moisture in the environment.
