Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sweat recording device, and more particularly to a device which is attached to a living body and detects and records the amount of sweat of the living body or the component of sweat, and further the temperature.

[0002]

2. Description of the Related Art A device for measuring the amount of sweat by carrying the device is known. For example, JP-A-5-3857 and JP-A-5-3857
In Japanese Patent No. 3875 or Japanese Patent Laid-Open No. 5-228122, the amount of sweat is measured from the electric resistance by fixing it to the wrist with a band, measuring the concentration of water vapor from the skin with a humidity sensor, or contacting the electrode with the skin. The measuring device is open to the public.

[0003]

However, these devices are of the type that they are fixed to the wrist with a band and cannot be easily applied even if they are applied to other parts of the human body. For example, when trying to measure perspiration on the neck, trying to fix the device firmly results in a tighter neck with the band, which is not possible.

Further, since the device itself is wrapped in a rigid case, the case does not adhere well to the human body even when it is attached to a site to which the band can be applied, and even if it is temporarily adhered to the body, Movement creates a gap that allows water vapor to escape, moisture from other parts to enter, making the humidity sensor's detection inaccurate. It showed an abnormal value.

In addition to water, sweat also contains components such as sodium chloride, potassium ions, pyruvic acid, lactic acid, sugar, creatinine, and ammonia, which are important data for investigating the condition of the living body. Becomes However, the conventional portable device described above can only detect the amount of sweat, that is, the amount of water, and does not detect any component in the sweat. Therefore, it was not possible to know the changes in the components in sweat, which was insufficient as data.

The present invention solves such a problem, and a perspiration recording apparatus which can be easily carried by being attached to a living body and which can accurately detect the amount of perspiration,
It is another object of the present invention to provide a sweat recording device capable of detecting sweat components and temperature.

[0007]

And a reading storage unit that reads and stores a detection value of the perspiration detection sensor.

According to a second aspect of the present invention, a flexible sheet-like substrate that can be attached to a living body on one side and a sweat component that is installed on the substrate and detects a specific component of sweat from the living body. A detection sensor, and a read storage unit that is installed on the base and reads and stores a detection value of the sweat component detection sensor,
A sweat recording device characterized by comprising:

According to a third aspect of the present invention, there is further provided output means which is installed on the base body and which outputs the recorded contents of the detected values stored in the read storage means to the outside according to an instruction from the outside. The sweat recording apparatus according to Item 1 or 2.

According to a fourth aspect of the present invention, at least a portion of the substrate on which the sensor is installed is made of a water permeable member, and when attached to a living body, at least the surface of the water permeable member is provided. A part is exposed to the outside.
The sweat recording apparatus according to any one of 1 to 3 above.

A fifth aspect of the present invention is the sweat recording apparatus according to the fourth aspect, wherein a water-absorbing substance is provided in contact with the water-permeable member. The invention according to claim 6 is the sweat recording apparatus according to any one of claims 1 to 5, wherein the read storage means reads and stores the detection value of the sensor in a predetermined time cycle.

According to a seventh aspect of the present invention, there is provided a flexible sheet-shaped substrate which can be attached to a living body on one side, and a perspiration amount detection sensor which is installed on the substrate and detects the amount of perspiration from the living body. A sweat component detection sensor installed on the base body for detecting a specific component of sweat from the living body; and a sweat value detection sensor installed on the base body for reading and storing a detection value of the sweat amount detection sensor. A perspiration recording device comprising: a reading storage unit that reads and stores the detection value of the sweat component detection sensor when it is determined from the detection value of the sensor that the perspiration amount is a predetermined value or more. .

The invention according to claim 8 further comprises a temperature sensor installed on the base for detecting the temperature of the living body, wherein the reading and storing means also reads and stores a detection value of the temperature sensor. The sweat recording apparatus according to any one of claims 1 to 7.

Here, in the sweat recording apparatus according to the first aspect, the substrate has a flexible sheet shape which can be attached to a living body on one surface side. The sweat rate detection sensor is installed on the base body and detects the sweat rate from the living body. Therefore, the sweat recording device can be attached along the shape of most of the living body to be attached. Therefore, the sweat rate detection sensor can be brought into close contact with the living body and can follow the shape of the living body, preventing abnormal measurement.

Further, since the reading / storing means reads and stores the detection value of the perspiration amount detection sensor, the data of the perspiration amount of the living body can be obtained by reading the stored contents later. Further, in the sweat recording device according to claim 2, a sweat component detecting sensor is used instead of the sweat amount detecting sensor.
It is installed on this substrate and detects a specific component of sweat from the living body.

Therefore, the sweat component of the living body can be detected, the sweat component detecting sensor can be in close contact with the living body, can follow the shape change of the living body, and prevent abnormal measurement. Then, since the reading storage means reads and stores the detection value of the sweat component detection sensor, the data of the components in the sweat of the living body can be obtained by reading the stored contents later.

The configurations of claims 1 and 2 may be combined.
In addition to the above configuration, an output unit may be provided which is installed on the base and outputs the recorded content of the detected value stored in the read storage unit to the outside according to an instruction from the outside. In this way, the recorded contents can be read and used as needed.

At least a portion of the base body on which the sensor is installed is made of a water-permeable member so that at least a part of the surface of the water-permeable member is exposed to the outside when it is attached to a living body. It may be configured to. According to this structure, while the sweat from the living body passes through the water-permeable member to the part exposed to the outside, the perspiration amount, the kind of the sweat component or the amount of the sweat component is detected by the sensor. To be detected. Since only sweat passes around the sensor, new sweat is constantly supplied and an accurate detection value can be obtained in real time. The sweat that reaches the exposed part evaporates on the surface of the exposed part, and the non-evaporable components of sweat solidify on the surface,
Alternatively, sweat is absorbed by clothes and hardly affects the sensor.

Further, a water absorbing material may be provided in contact with the water permeable member. Examples of the water absorbent substance include a water absorbent resin and a desiccant. Examples of the desiccant include silica gel, calcium chloride, calcium oxide and the like. By bringing the water-absorbent substance into contact with the water-permeable member in this manner, the flow of sweat from the living body to the water-absorbent substance continues for a long period of time, so that accurate measurement by the sensor can be performed for a long period of time. If the water-absorbing substance is not in contact, it will be due to only evaporation of the exposed part, and the sweat component will accumulate around the exposed part. If this is for a long period of time, the detection value of the sensor, particularly the detection of the sweat component detection sensor, tends to be inaccurate, so it is preferable to bring the water-absorbing substance into contact with the water-permeable member.

If the reading / storing means is configured to read and store the detection value of the sensor in a predetermined time period, it is more useful because the data of the sweating amount and the time change of the component can be obtained. . Further, both a perspiration amount detection sensor and a perspiration component detection sensor are provided, and the reading storage means reads and stores the detection value of the perspiration amount detection sensor, and the perspiration of a predetermined value or more from the detection value of the perspiration amount detection sensor. When it is determined that the amount is the amount, the detection value of the sweat component detection sensor may be read and stored.

When the amount of sweat is small, the detection of the component is likely to be inaccurate. Therefore, only when the amount of sweat necessary for the detection of the sweat component detection sensor is obtained, the detection value of the sweat component detection sensor is obtained. Is preferably read. Further, in order to detect a plurality of components, when a plurality of sweat component detection sensors are provided, when the amount of sweat required for accurate measurement differs for each sweat component detection sensor, for each sweat component detection sensor,
The read storage means may store the output value of the sweat component detection sensor when the required sweating amount is obtained.

Further, it is preferable to provide a temperature sensor, detect the temperature of the living body, and store the temperature in the reading storage means because more knowledge can be obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

[First Embodiment] FIG. 1 is an overall perspective view of a sweat recording apparatus 2 according to a first embodiment of the present invention, and FIG. 2 is a rear perspective view of the sweat recording apparatus 2.

The perspiration recording device 2 includes a substrate 4 mainly composed of a water-permeable synthetic paper which is permeable to perspiration and does not break even if it gets wet with perspiration, a flexible first plastic sheet 6 which is impermeable to perspiration, and a perspiration which is also impermeable to perspiration. It comprises a flexible second plastic sheet 8, a thin mesh sheet 9 and a measurement recording circuit 10 provided on the substrate 4.

As shown in the plan view of FIG. 3, the base body 4 is a water-permeable synthetic paper cut into a slightly thicker rectangle, and has a battery case storage hole 4a for a microcomputer, a battery case storage hole 4b for a measurement circuit and a signal input. Open hole for output terminal 4

As shown in the plan view of FIG. 4, the first plastic sheet 6 is a plastic sheet thinner than the base body 4, and has a battery case opening hole 6a for microcomputer, a battery case opening hole 6b for measuring circuit, and a signal input / output terminal. The open hole 6c and the moisture release open hole 6d are provided as through holes.

As shown in the back view of FIG. 5 (a), the second plastic sheet 8 is a plastic sheet thinner than the substrate 4, and has perforation holes 8a for introducing sweat. The back surface of the second plastic sheet 8 is coated with an adhesive and is covered with a release paper 8b.

The mesh sheet 9 has a rectangular shape as shown in FIG. 5B, and is slightly larger than the perforation opening 8a of the second plastic sheet 8. The mesh sheet 9 is used to cover the sweat introduction opening 8a. As shown in the plan view of FIG. 6, the measurement recording circuit 10 includes a microcomputer 12, a power supply unit 14 thereof, a signal input / output terminal 16 with an external reading device, a measurement circuit 18, a power supply unit 20 thereof, and a sweating amount detection sensor 22. 2 electrodes 22a and 22b, a sodium ion sensor 24, a potassium ion sensor 26, a pH sensor 28, and a pyruvic acid sensor 30.

Power supply unit 14 for the microcomputer 12
The power supply unit 20 for the measuring circuit 18 has plastic battery cases 14a, 20a, respectively, in which the batteries 14b, 20b can be stored, and the microcomputer 12
Alternatively, power is supplied to the measurement circuit 18.

These constructions are formed on a thin plastic sheet 32 which is cut along the arrangement of the constructions. The electrodes 22a and 22b of the sweat rate detection sensor 22, the signal input / output terminals 16 and lines for connecting the respective components are formed by printing conductive paint. Further, the microcomputer 12 and the measurement circuit 18 are configured by a method of directly attaching an IC chip having the function to the plastic sheet 32. Sodium ion sensor 24, potassium ion sensor 26 and pH sensor 28
Similarly, a semiconductor ion sensor having the same function is attached to the plastic sheet 32. Further, the pyruvate sensor 30 is configured by attaching an element, which is a combination of immobilized pyruvate oxidase and an oxygen sensor composed of a solid electrolyte, to the plastic sheet 32.

The sensors 22 to 30 and the signal input / output terminal 1
Except for 6, the waterproof coating is applied to prevent corrosion due to sweat. In this way, the measurement recording circuit 10 is configured in a flexible sheet shape. Moreover, the plastic sheet 32
Is more flexible because it is shaped according to each configuration of the measurement recording circuit 10.

The detection signals of these sensors 22 to 30 are input to the measuring circuit 18, and the read signal specifying the sensor is sent from the microcomputer 12 to the measuring circuit 18 to the measuring circuit 1.
When output to 8, the measurement value of the corresponding sensor is output from the measurement circuit 18 to the microcomputer 12 as a data signal. This data is stored in the RAM in the microcomputer 12.

When the microcomputer 12 receives a data output command from an external device via the signal input / output terminal 16, the microcomputer 12 outputs the measurement data stored in the RAM from the signal input / output terminal 16 to the outside. Output the data to the device. The perspiration recording apparatus 2 is configured by assembling these configurations as follows. First, the second plastic sheet 8 is located at the bottom. Opening hole 8 for introducing sweat into the second plastic sheet 8
The surface a is covered with a mesh sheet 9 whose periphery is fixed with an adhesive. The measurement recording circuit 10 is located on these. The base body 4 is located on the measurement recording circuit 10 in the battery case storage hole 4a for the microcomputer and the battery case storage hole 4b for the measurement circuit, respectively.
The plastic battery cases 14a and 20a are fitted. And the first plastic sheet 6 on top
The microcomputer battery case opening hole 6a is used as a microcomputer battery case housing hole 4a, the measurement circuit battery case opening hole 6b is used as a measurement circuit battery case housing hole 4b, and the signal input / output terminal opening hole 6c is used as a signal. It is located in line with the input / output terminal open hole 4c.

The second plastic sheet 8 at the bottom and the substrate 4 are bonded with an adhesive at a portion where the measurement recording circuit 10 does not exist between them. The base 4 and the first plastic sheet 6 on the top are completely bonded with an adhesive. In addition, the batteries 14b and 20b are finally put in the plastic battery cases 14a and 20a, and the seal 14
c and 20c are attached, and the batteries 14b and 20b inside are sealed.

In the measurement recording circuit 10 sandwiched between the second plastic sheet 8 at the bottom and the substrate 4, the plastic battery cases 14a and 20a are the battery case storage holes 4a for the microcomputer of the substrate 4. Since the second plastic sheet 8 and the base body 4 are fitted in the battery case storage hole 4b for the measurement circuit and the measurement recording circuit 10 is adhered around the measurement recording circuit 10, they are adhered to other structures. Even if not, the position of the measurement recording circuit 10 is firmly fixed.

The perspiration recording apparatus 2 removes the release paper 8b on the back surface of the second plastic sheet 8 to remove the second plastic sheet 8 from the second plastic sheet 8.
It is used by exposing the adhesive on the entire back surface of the plastic sheet 8 and adhering it to the surface of a living body, here a portion of the human body to be measured. When the sweat recording apparatus 2 is attached to a human body, the mesh sheet 9 is exposed on the back surface side through the sweat introduction opening 8a of the second plastic sheet 8, so that the mesh sheet 9 is directly exposed. Touch the skin of the human body. Since it is a mesh, the sweat generated on the skin is
A sensor 22 for detecting the amount of perspiration that easily passes and is inside
Contact the electrodes 22a and 22b of, and also wet the substrate 4.
As a result, the electric resistance between the electrodes 22a and 22b is reduced, and the measured value is converted into the amount of perspiration in the measuring circuit 18. Moreover, since the other four sensors 24 to 30 are also wetted,
Sodium ion, potassium ion, pH and pyruvic acid are respectively detected and converted into concentration values by the measuring circuit 18.

The perspiration after reaching each of the sensors 22 to 30 passes through the substrate 4 and goes to the moisture release opening 6d of the first plastic sheet 6 to reach the moisture release opening 6d.
It is evaporated on the surface of the substrate 4 exposed to the air or is absorbed by clothes. In this way, the sweat generated from the skin constantly flows toward the water discharge opening hole 6d, and the sensors 22 to 30
Since the sweat that comes into contact with is constantly changing, an accurate value can always be measured.

Further, in the sweat recording apparatus 2, since each of the above-mentioned constitutions is made of the flexible sheet body, it is possible to follow the unevenness of the human body and the change of the unevenness, and further, the sweat introduction opening hole 8a for introducing sweat is provided. Since the second plastic sheet 8 on the periphery is firmly adhered to the skin by the adhesive, the amount of sweat actually generated from the skin can be reflected as it is in the range of the opening hole 8a for introducing sweat.

Next, the detection / recording process performed by the microcomputer 12 in this measurement will be described with reference to the flowchart of FIG. This process is started by the microcomputer 12 by attaching a start signal to the measurement recording circuit 10 via the signal input / output terminal 16 by an external device after attaching the sweat recording device 2 to a human body.

When the process is started, it is first determined whether or not a predetermined time has passed (S100). This may be determined in units of minutes, seconds or hours, and may be appropriately determined according to the content of measurement or the measurement period. The predetermined time may be input from the signal input / output terminal 16 prior to the start of this processing.

Until the predetermined time has passed, step S10
When the time is 0, the output of one sensor is detected when a predetermined time has passed (S110). That is, a process of instructing the measurement circuit 18 to convert the output of a predetermined sensor into a measured value and transmitting the measured value is performed. Then, the received measurement value is read along with the read data (timer data) of the timer built in the microcomputer 12
The data is stored in the area provided for each sensor in the AM (S1
20).

Next, it is determined whether or not there are any remaining sensors that have not been measured this time (S130), and if there are any, the processes of steps S110 and S120 are repeated for the next sensor. All sensors, that is, the sweat rate detection sensor 22, the sodium ion sensor 24, the potassium ion sensor 26, the pH sensor 28, and the pyruvic acid sensor 30.
If the measured value of is obtained, a negative determination is made in step S130, and it is then determined whether or not the measurement has been performed a predetermined number of times (S).
140). This predetermined number of times corresponds to the capacity of the storage area of the RAM, and is for checking that the measured value does not exceed the memory. Therefore, if the measurement for the predetermined number of times has not been completed, a negative determination is made in step S140, the process returns to step S100, and the above processing is repeated. If the measurement for the predetermined number of times has been completed, an affirmative determination is made in step S140. Then the processing ends.

Next, in order to obtain the measurement result, the perspiration recording device 2 after the measurement or the perspiration recording device 2 is disassembled and only the measurement recording circuit 10 is connected to the desktop computer 50 shown in FIG. This is done by putting it in the reading device 52. That is, the terminal of the reading device 52 comes into contact with the signal input / output terminal 16 of the sweat recording device 2, and the read instruction from the desktop computer 50 is transmitted.
To the measurement recording circuit 10. As a result, the measurement recording circuit 10 of the sweat recording device 2 outputs the measurement value to the desktop computer 50 via the reading device 52.

A recording data output process started by the microcomputer 12 of the measurement recording circuit 10 in response to a read command from the desktop computer 50 is shown in the flowchart of FIG. When the process is started, first, the sensor recording data for one sensor is output to the outside from the signal input / output terminal 16 together with the timer data (S20).
0). The desktop computer 50 receives this signal and stores it in a hard disk or the like.

Next, it is judged whether or not there is a remaining sensor that is not outputting (S210), and if there is, the process of step S200 is repeated again. When the output of the print data of all the sensors is completed, a negative determination is made in step S210, the print data stored up to now in a predetermined area in the RAM is erased (S220), and the process ends.

Since the sweat recording device 2 of the present embodiment is constructed in such a flexible manner, the sweat recording device 2 can be attached along the shape of almost any part of the living body to which it is attached. Moreover, it can follow the changes. Therefore, the sweat rate detection sensor 22 can always be in close contact with the living body, and abnormal measurement can be prevented.

Then, since the microcomputer 12 reads and stores the detection value of the perspiration amount detection sensor 22, the data of the perspiration amount of the living body can be obtained by reading the stored contents later. In addition to the sweat rate detection sensor 22, each sensor 24 to 30 as a sweat component detection sensor is installed on the base 4 and detects a specific component of sweat from the living body, so that the sweat component of the living body is detected. At the same time, these sensors 24 to 30 can always be in close contact with the living body, and abnormal detection of the detected value can be prevented.

Similarly, the microcomputer 12
However, since the detection values of the sensors 24 to 30 are read and stored, the data of the components in the sweat of the living body can be obtained by later reading the stored contents. Also,
In response to an instruction from the outside, the microcomputer 12 outputs the recording data of the detected value stored via the signal input / output terminal 16 to the outside, so that the recording contents can be read and used as necessary. .

The substrate 4 is made of a water-permeable material, and when attached to a living body, the water release opening 6d is formed on the surface of the substrate 4.
Is exposed to the outside, the water-releasing open hole 6 penetrates the inside of the water-permeable substrate 4.
While passing through d, the sensors 22 to 30 detect the amount of sweat, the type of sweat component, or the amount of the component. Since only the sweat passes around the sensors 22 to 30,
New sweat is constantly supplied, and accurate detection values can be obtained in real time. The perspiration that has reached the moisture release opening 6d evaporates on the surface of the substrate 4, and the non-evaporated component of the perspiration solidifies on the surface, so that it hardly affects the sensors 22 to 30.

Further, since the microcomputer 12 reads and stores the detection values of the sensors 22 to 30 in a predetermined time period, it is useful because it can obtain the data of the sweating amount and the time change of the component. In the present embodiment, the processing of FIG. 7 corresponds to the processing as the reading and storing means, and steps S200, S
210 corresponds to the process as an output means.

[Embodiment 2] This Embodiment 2 differs from Embodiment 1 in that the detection / recording processing shown in FIG. 10 is performed instead of the detection / recording processing (FIG. 7) of Embodiment 1. Others are the same as those of the first embodiment.

When this processing is started, a predetermined time is waited (S
After 300), the amount of perspiration is detected by the perspiration detection sensor 22 (S310). This is stored together with the timer data in the area provided for each sensor in the RAM (S320). Next, it is determined whether or not this sweating amount is equal to or more than a predetermined value (S330). If it is less than the predetermined value, it is then determined whether or not the predetermined number of times has been measured (S370), and if the predetermined number of times has not been measured, the process returns to step S300 again.

If the amount of perspiration is equal to or greater than the predetermined value in step S330, the detection by the sweat component detection sensor (S34
0) and the measured value thereof are stored in the RAM together with the timer data (S350) in the determination of step S360 for all of the sensors 24 to 30 and detected for all the sweat component detection sensors 24 to 30 (S340). When the storage of the measured value / timer data (S350) is completed, a negative determination is made in step S360, and the determination of step S370 is made. Thereafter, if the measurement of the predetermined number of times has not been completed, a negative determination is made in step S370 and the process is repeated by returning to step S300. If the measurement of the predetermined number of times is completed, an affirmative determination is made in step S370 to detect. The recording process ends.

Since this embodiment is constructed in this way, it exhibits the following effects in addition to the effects of embodiment 1. That is, when the microcomputer 12 reads and stores the detection value of the sweat rate detection sensor 22 and determines from the detection value of the sweat rate detection sensor 22 that the sweat rate is a predetermined value or more, the sweat component detection sensor The detection values of the respective sensors 24 to 30 are read and stored. If the amount of sweat is small, the detection of the component is likely to be inaccurate, so read the detection value of the sweat component detection sensor only when the amount of sweat necessary for the detection of the sweat component detection sensor is obtained in this way. As a result, accurate component measurement values are obtained.

In the second embodiment, the processing of FIG. 10 corresponds to the processing as the reading and storing means. Embodiment 3 FIG. 11 shows Embodiment 3 in which the water absorbent material 70 is further attached to the first plastic sheet 6 in addition to the configurations of Embodiments 1 and 2.

The water-absorbent substance 70 is in contact with the substrate 4 through the water discharge opening 6d of the first plastic sheet 6. The water-absorbent substance 70 is a water-absorbent plastic and can absorb a large amount of water used for sanitary products and the like. Therefore, the sweat that has reached the moisture release opening 6d is absorbed by the water-absorbing substance 70 and does not stay on the substrate 4. Therefore, the flow of sweat around each sensor 22 to 30 is maintained for an extremely long time, and accurate measurement can be performed for an extremely long time.

Further, the first plastic sheet 76 as shown in FIG. 12 is formed without providing a window such as the moisture release opening 6d of the first plastic sheet 6, and the water-absorbing substance 70 is directly adhered to the substrate 4. May be. [Others] In each of the above-described embodiments, a sodium ion sensor 24, a potassium ion sensor 26, a pH sensor 28, and a pyruvic acid sensor 30 are provided as a sweat component detection sensor that detects a specific component of sweat. A component sensor, for example, a sensor for detecting a component such as lactic acid, sugar, creatinine, or ammonia may be provided to obtain more multifaceted data.

Input / output of signals to / from the outside may be performed not through the signal input / output terminal 16 but through a radio input / output device using radio waves or infrared rays. For radio waves, open hole 4 for signal input / output terminals
It is not necessary to provide c and 6c. Further, when the amount of perspiration necessary for accurate measurement is different for each of the sensors 24 to 30 as the sweat component detection sensor, the required amount of perspiration is detected by the perspiration amount detection sensor 22 for each of the sensors 24 to 30. If so, the microcomputer 12 may store the measurement values detected by the sensors 24 to 30.

In the third embodiment, as shown in FIG. 13, the sensors 24 to 30 may be projected longer. The same applies to the first and second embodiments. In each of the above embodiments, the two power supply units 14 and 20 are provided for the microcomputer 12 and the measurement circuit 18, but they may be shared and only one power supply unit may be provided.

In each of the above embodiments, the measurement recording circuit 10 is
The measurement recording circuit 10 can be taken out by peeling off the second plastic sheet 8 of the perspiration recording device 2 and the substrate 4 because they are mechanically fixed and not fixed with an adhesive in any of the configurations. If the measurement recording circuit 10 is assembled by using the new substrate 4, the first plastic sheet 6, the second plastic sheet 8 and the mesh-shaped sheet 9, the measurement recording circuit 10 using an expensive IC chip is reproduced. It is available and truly economical. Of course,
The measurement recording circuit 10 may be attached to the base 4 or the second plastic sheet 8 with an adhesive having a low adhesive force. Also in this case, since the adhesive force is weak, it can be easily peeled off and reused.

The mesh-like sheet 9 may be a thin net-like material, but may be paper, or paper of the same quality as the substrate 4 and thinner than the substrate 4. Electrode 2 of perspiration detection sensor 22
Although the mesh-like sheet 9 exists between the skin 2a, 22b and the skin, the electrodes 22a, 22b may directly contact the skin. Further, the sweat rate detection sensor 22 includes electrodes 22a, 22
Although b is used, a humidity sensor made of a semiconductor like the sensors 24 to 30 may be used.

Further, in each embodiment, if a temperature sensor is further provided and recording is performed in the same manner as the other sensors, further new knowledge can be obtained.
