On the other hand, no consideration or countermeasures have been taken regarding the effects of electromagnetic waves emitted from electrical structures such as sensors and wiring on the foetation and / or pregnant women. Even if the electromagnetic waves emitted by the individual sensors are small, when a large number of sensors are arranged in the pregnant woman's belt or the like, the total amount of electromagnetic waves cannot be ignored, or even if it can be ignored, it causes anxiety to the pregnant woman. Electromagnetic waves heat cells and can cause cell damage and the like. The effect can be particularly significant for fetuses with high frequency of cell division.

The description of the present specification is merely a typical example, and does not limit the scope of claims or application examples of the present disclosure in any sense.

In this embodiment, the description is given in sufficient detail for those skilled in the art to implement the present disclosure, but other implementations and embodiments are also possible and do not deviate from the scope and spirit of the technical idea of the present disclosure. It is necessary to understand that it is possible to change the structure and structure and replace various elements. Therefore, the following description should not be construed as limited to this.

[First Embodiment]
With reference to FIG. 1 which is a schematic visible view explaining the overall configuration of the pregnant woman band 1 and FIG. 2 which is a cross-sectional view of the pregnant woman band 1, the pregnant woman band as a biological information monitoring device according to the first embodiment. 1 will be described. The pregnant woman band 1 includes a cloth body 10, a sensor 20, a control unit 30, a wiring layer 40, and an electromagnetic wave shield 12. The cloth body 10 is configured to be wearable so as to cover at least a part of the abdomen of a pregnant woman. The sensor 20 is mounted on the cloth body 10 and detects a biological signal from the abdomen. The control unit 30 controls the sensor 20. The wiring layer 40 connects the sensor 20 and the control unit 30. The electromagnetic wave shield 12 is arranged between at least one of the sensor 20, the control unit 30, and the wiring layer 40 and the abdomen of the pregnant woman when worn, and the electromagnetic wave shield 12 is arranged between the sensor 20, the control unit 30, and the wiring layer 40. It is configured so that the propagation of electromagnetic waves generated by the sensor can be suppressed.

The cloth body 10 is configured to be wearable so as to cover the abdomen of the pregnant woman, and is preferably made of a material that can be expanded and contracted according to the movement of the pregnant woman's body, the movement of the foetation, and the like. As an example, the cloth body 10 can be a tubular belly band type as shown in FIG. However, the shape of the cloth body 10 is not limited to this, and for example, a pants type, a girdle type, a belt type, or a band type cloth body 10 can be adopted. In either case, it is preferable that the sensor 20 mounted on the cloth body 10 can come into contact with or approach the abdomen of the pregnant woman via the cloth body 10.

The cloth body 10 can be composed of various materials usually used for clothing. For example, natural fibers such as cotton, linen and hair, chemical fibers such as polyester, nylon and acrylic, or fibers in which these materials are mixed can be used. Cloth so that the pregnant woman who wears the clothes can act naturally without difficulty when wearing a normal pregnant woman's belt, and at the same time, the movement of the pregnant woman and the fetal movement information of the fetal can be detected with high sensitivity. 10 is preferably in close contact with the wearer as much as possible. Therefore, the cloth body 10 is not limited to this, but a stretch material having an elasticity of at least 5% or more, which is a mixture of elastic fibers such as polyurethane based on cotton or polyester fibers, is preferable. In this case, the mixing ratio is preferably 1% to 50%, more preferably 3% to 30%. Instead of the stretch material, for example, a conventional natural fiber material may be sewn with a stretchable rubber cord. If the sensor 20 installed on the cloth body 10 is stretchable, the stretchability of the cloth body 10 is preferably such that the characteristics of the sensor 20 can be sufficiently exhibited. For example, when the sensor 20 exhibits suitable performance in a stretch ratio of 50% or less and tears when the stretch ratio exceeds 100%, the stretch ratio required for the cloth 10 is preferably 100% or less, and more. It is preferably slightly below 50%, for example 40% to 50%.

The sensor 20 is mounted on the cloth body 10 and detects a biological signal from the mother (or foetation). The cloth body 10 and the sensor 20 can be joined by a method such as an adhesive or hot melt, but the present invention is not limited to this. As long as the sensor 20 can be fixedly arranged with respect to the cloth body 10, the method is irrelevant. Further, the sensor 20 may or may not be removable when cleaning the pregnant woman's band 1. The sensor 20 is preferably arranged mainly near the abdomen of the mother in order to accurately detect the fetal movement signal of the fetal body, but depending on the type of the sensor 20, the sensor is placed in another place, for example, on the substrate of the control unit 30. It is also possible to install 20. For example, an acceleration sensor, a gyro sensor, a geomagnetic sensor, etc., which will be described later, can be arranged and used in the control unit 30. Although not shown, the actuator may be arranged on the cloth 1 in addition to the sensor 20. When the sensor 20, the actuator, or the like is arranged at a position corresponding to the abdomen, as described later, in order to suppress the propagation of electromagnetic waves to the abdomen, the electromagnetic wave shield 12 described later may be arranged between the sensor 20 and the abdomen of the pregnant woman. preferable.

The sensor 20 can be freely selected from various sensors such as analog and digital sensors according to the type and strength of the signal to be detected. As an example, the sensor 20 can include a strain sensor, an acceleration sensor, a gyro sensor, a pressure sensor, an optical sensor, a geomagnetic sensor, a temperature sensor, a piezoelectric sensor and the like. In particular, strain sensors, acceleration sensors, gyro sensors, and pressure sensors are suitable for detecting fetal movement signals. Further, as an example, the sensor 20 can include bioelectrodes such as ECG and EMG. These bioelectrodes are suitable for detecting biological signals such as fetal heartbeat, exercise, and pregnant woman's heartbeat and uterine contraction. A combination of a plurality of types and a plurality of sensors including these sensors may also be selected. For example, strain sensors, pressure sensors, etc., which are excellent for measuring biological signals close to a single fetal body, and acceleration sensors, gyro sensors, etc., which are excellent for measuring biological signals affected by both fetal and pregnant women. By combining the above, the biological signals of the fetal unit and the pregnant woman alone can be estimated.

The stretchable sensor is installed on the stretchable cloth 10 and the electromagnetic wave shield 12 so that the sensor can fully exhibit its characteristics. In addition, among the stretchable sensors, for sensors with a relatively large area, such as strain sensors, from the viewpoint of comfort, a pregnant woman who is a wearer of clothes wears a normal pregnant woman's belt as well as a cloth. It is preferable to have at least 5% or more elasticity so that the patient can act naturally without difficulty, and at the same time, the movement of the pregnant woman and the fetal movement information of the fetal can be detected with high sensitivity.

FIG. 1 shows an example of a wiring structure when a resistance type analog sensor is selected as the sensor 20 and a circuit for measuring the resistance value of the resistance type analog sensor, for example, a voltage dividing circuit, is installed in the control unit 30. Although shown, it is not particularly limited to this. As the strain sensor, a resistance type strain sensor is preferable. The method for producing the resistance type strain sensor is arbitrary, but as an example, it can be produced by printing conductive ink. In that case, it is preferable to use a water-based conductive ink instead of an organic solvent-based ink in consideration of the influence of a harmful residual solvent such as formaldehyde and workability.

The wiring layer 40 is mounted on the cloth body 10 like the sensor 20. The material used for the wiring layer 40 may be any material in any form as long as it is suitable for wiring. Any material / component generally used for wiring may be used. Further, a material such as a metal wire, a metal foil, a thread whose surface is coated with metal, or a conductive material such as a conductive polymer is also good. Further, these materials may be coated with a non-conductive material. These may be used alone, in combination with these, or in combination with other materials such as polymers, rubber, ceramics, cloth, paper, leather and the like. As an example, wiring for installing coated metal wiring on the cloth body 10 by adhesion, wiring for installing metal-plated thread by sewing, wiring using cloth made by knitting metal-plated thread, and the like. Can be mentioned. The metal used for the metal wire, the metal foil, the thread whose surface is coated with the metal, and the like may be any material as long as it is suitable for wiring. For example, aluminum, titanium, chromium, iron, nickel, copper, silver, tungsten, platinum, tin, zinc, gold and the like can be mentioned. It is also possible to use these alloys. Specific examples of the alloy include beryllium copper, zirconium copper, brass, bronze, phosphor bronze, titanium copper, cupronickel and the like. It is also possible to use a metal wire coated with metal. Further, the printed wiring may be printed on the cloth body with the conductive ink. In that case, it is preferable to use a water-based conductive ink instead of an organic solvent-based ink in consideration of the influence of a harmful residual solvent such as formaldehyde and workability.

The wiring layer 40 may be configured to include, for example, only wiring, or may be configured to include, for example, a support for wiring in addition to wiring. The wiring layer preferably has at least 5% or more elasticity. As the elasticity of the wiring layer, the elasticity of the material may be used, or the elasticity of the wiring installation method may be used. For example, by arranging the non-stretchable wiring material formed in a string shape in a shape such as a sine curve or a continuous horseshoe shape, the stretchability of the entire structure of the wiring layer can be ensured. The elasticity of the wiring layer of the present patent may be ensured by a method including these two methods or a method not including these two methods.

When the wiring layer 40 is arranged at a position corresponding to the abdomen, it is preferable to arrange the electromagnetic wave shield 12 described later between the wiring layer 40 and the abdomen of the pregnant woman in order to suppress the propagation of the electromagnetic wave to the abdomen as described later.

The sensor 20 and the wiring layer 40 are collectively referred to as a "conductive layer 14". FIG. 2 shows a cross-sectional view of the pregnant woman band 1. The conductive layer 14 can be installed as it is on the cloth 10 or a laminated body of the cloth 10 and the electromagnetic wave shield 12, but it is preferable that the conductive layer 14 is laminated so as to be sandwiched between the

protective layers

13 and 15 on the upper and lower surfaces thereof. ..

The protective layers 13 and 15 have a role of preventing the conductive layer 14 from being short-circuited with the outside by sandwiching the conductive layer 14 from both sides thereof, and preventing corrosion and damage thereof. The protective layers 13 and 15 preferably have elasticity so that the sensor 20 and / or the wiring layer 40, which are collectively referred to as the conductive layer 14, can sufficiently exhibit its characteristics. In addition, so that the pregnant woman who wears the clothes can act naturally without difficulty as when wearing a normal pregnant woman's belt, and at the same time, the movement of the pregnant woman and the fetal movement information of the fetal can be detected with high sensitivity. It preferably has at least 5% elasticity. As an example, the

protective layers

13 and 15 may be composed of an elastomer composition containing an elastomer such as a rubber / resin, particularly a silicone rubber / polyurethane film, but the

protective layers

13 and 15 are not limited thereto.

The control unit 30 is connected to the sensor 20 via the wiring layer 40, receives a detection signal from the sensor 20, determines the state of the foetation or the mother, and provides the sensor 20 with a drive signal and an operating voltage. The control unit 30 may have a battery, a memory function, a display function, or the like, or may have a transmitter and can be wirelessly connected to, for example, an external server, a cloud, or a terminal such as a PC or mobile phone. .. In that case, the transmitted detection information of the sensor 20 is subject to analysis on the server or the like, and the analysis result is appropriately transmitted to the user of the pregnant woman's belt (pregnant woman) for the purpose of maternal and fetal health management and the like. Can be used for. Examples of transmitters include Bluetooth, BLE, Wi-Fi and any other method used for wireless communication.

The control unit 30 may or may not be removable when cleaning the pregnant woman band 1. Further, the control unit 30 may be arranged at a position corresponding to the abdomen, or a position away from the position corresponding to the abdomen (for example, the back surface) in order to suppress the electromagnetic waves emitted by the control unit 30 from propagating to the abdomen. Can be placed on the side). When the control unit 30 is arranged at a position corresponding to the abdomen, it is preferable to arrange the electromagnetic wave shield 12 described later between the control unit 30 and the abdomen of the pregnant woman in order to suppress the propagation of the electromagnetic wave to the abdomen as described later. The control unit 30 may have a fitting portion (not shown) formed on the electromagnetic wave shield 12 and mounted on the cloth body 10 in a form of being fitted into the fitting portion.

In the pregnant woman band 1 as shown in FIG. 1, it is necessary to arrange a large number of sensors 20 on the cloth 10 when trying to detect various biological signals from a foetation or a mother. When a signal flows through each sensor 20, an electromagnetic wave is generated based on the signal. Even if the electromagnetic waves from the individual sensors 20 are weak, when a large number of sensors 20 are arranged on the cloth 10, the total magnitude of the electromagnetic waves can be a non-negligible magnitude. In this case, there is concern about the influence of electromagnetic waves on the mother and foetation. Further, similar signals and digital communication data are transmitted and received not only to the sensor 20 but also to the control unit 30 and the wiring layer 40, and electromagnetic waves are generated based on the same signals and digital communication data. In addition, electromagnetic waves are generated as the circuit of the control unit 30 operates. In particular, when the control unit 30 includes a transmitter, electromagnetic waves are generated from the transmitter.

Therefore, the pregnant woman band 1 of the first embodiment is a cloth adjacent to the sensor 20, the control unit 30, the wiring layer 40, and the abdomen of the pregnant woman in order to suppress / block the propagation of such electromagnetic waves to the mother body. An electromagnetic wave shield 12 is provided between the bodies 10 to block such electromagnetic waves and suppress their propagation to the mother body side.

The electromagnetic wave shield 12 is provided between the cloth body 10 and the protective layer 13 in this example, and is provided between the sensor 20 and / or the wiring layer 40 collectively referred to as the conductive layer 14 and at least a part of the abdomen of the pregnant woman. Has been done. The electromagnetic wave shield 12 is also provided between the control unit 30 and the cloth body 10. In other words, the electromagnetic wave shield 12 is provided between the control unit 30 and at least a part of the abdomen of the pregnant woman. The electromagnetic wave shield 12 has a function of suppressing or blocking electromagnetic waves generated from the sensor 20 and / or the wiring layer 40, which are collectively referred to as the conductive layer 14, and the control unit 30. The electromagnetic wave shield 12 has a certain degree of conductivity for at least electromagnetic shielding.

As an example, the electromagnetic wave shield 12 may be composed of a set of metal wires, a single or laminated metal foil, or a set of metal threads. The electromagnetic wave shield made of the above-mentioned material can be made elastic by the structure, if necessary. For example, a metal wire formed in a mesh shape, a metal foil formed in a shape such as a sine curve or a continuous horseshoe shape, a metal thread woven in a knit shape, etc. suppress breakage due to expansion and contraction due to its structure, and have elasticity. It can be an electromagnetic shield.

The conductive portion of the electromagnetic wave shield 12 can also be made of a conductive material other than metal. The conductive material here need only have a certain degree of conductivity, and may be composed of, for example, an insulating material in which carbon nanotubes, graphene, carbon fibers, graphite, and metal nanoparticles are dispersed. Further, the electromagnetic wave shield 12 may be formed by combining a metal and a conductive material other than these metals with an insulating material such as cloth, resin, or rubber. Specifically, a metal material formed by plating / adhesion or suturing on an insulating material such as cloth / resin or rubber can be used as the electromagnetic wave shield 12. Further, the conductor is not limited to the metal, and a conductive organic substance can also be used. Further, in addition to the conductive material, a material treated for antistatic treatment can also be adopted. These materials can also be stretched by any method, if necessary. The material / configuration used for the wiring layer 40 can also be used for the material / configuration of the electromagnetic wave shield 12.

Regarding the electromagnetic wave shield 12 introduced for the purpose of suppressing or blocking the electromagnetic waves generated from the sensor 20 and the wiring layer 40 constituting the conductive layer 14, the sensor 20 and the wiring layer 40 constituting the conductive layer 14 have the characteristics. It is preferable to have elasticity so that it can be sufficiently exerted. In addition, so that the pregnant woman who wears the clothes can act naturally without difficulty as when wearing a normal pregnant woman's belt, and at the same time, the movement of the pregnant woman and the fetal movement information of the fetal can be detected with high sensitivity. It preferably has at least 5% elasticity. The electromagnetic wave shield 12 introduced for the purpose of suppressing the electromagnetic waves generated from the control unit 30 does not necessarily have to have elasticity if the control unit 30 does not have elasticity.

The electromagnetic wave shield 12 is formed between the conductive layer 14 that functions as the sensor 20 or the wiring layer 40 as described above, the control unit 30, and the cloth body 10 adjacent to the abdomen of the pregnant woman, and is thereby generated from the sensor or the like. It has a function of suppressing or blocking electromagnetic waves. For example, when the sensor 20 formed on the conductive layer 14 is an acceleration sensor controlled by the control unit 30 by the I2C method, when this is operated, electromagnetic waves are generated around the sensor 20 and its wiring. .. In addition, electromagnetic waves are generated around the control unit 30. In particular, when the control unit 30 includes a transmitter, the generation of electromagnetic waves is remarkable. These electromagnetic waves are suppressed or blocked by the electromagnetic wave shield 12 so as not to exceed the cloth body 10 and reach the mother body side.

In the example shown in FIG. 2, the electromagnetic wave shield 12 has substantially the same end face positions as the protective layer 13, the conductive layer 14, the protective layer 15, and the control unit 30 located above the electromagnetic wave shield 12. As shown in 3 (modification example), the end face position of the electromagnetic wave shield 12 may be a position protruding from the end faces of the protective layer 13, the conductive layer 14, the protective layer 15, and the control unit 30. By making the size of the electromagnetic wave shield 12 larger than that of the conductive layer 14 in this way, the electromagnetic wave / electromagnetic field generated in the conductive layer 14 can be more effectively suppressed or blocked by the electromagnetic wave shield 12.

The electromagnetic wave shield 12 can also be protected by a protective layer in the same manner as the conductive layer 14. It is also possible to install two protective layers so as to sandwich the electromagnetic wave shield 12 on the upper and lower surfaces mainly to prevent corrosion and damage. Further, the electromagnetic wave shield 12 can share a protective layer with the conductive layer 14.

As described above, according to the pregnant woman band 1 of the first embodiment, the pregnant woman wearing the pregnant woman band 1 through the sensor 20, the control unit 30, the wiring layer 40, and the cloth body 10. The electromagnetic wave shield 12 formed between the abdomen of the baby suppresses or blocks the electromagnetic wave generated from the conductive layer 14, whereby the influence of the electromagnetic wave on the mother body can be suppressed.

[Second Embodiment]
Next, the pregnant woman band 1 according to the second embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a schematic perspective view illustrating the overall configuration of the pregnant woman band 1 according to the second embodiment. Further, FIG. 5 is a cross-sectional view including a portion of the conductive layer 14 in the second embodiment. Since the overall configuration (FIG. 1) may be the same as that of the first embodiment, duplicate description will be omitted below.

Similar to the first embodiment, the pregnant woman band 1 of the second embodiment is provided with an electromagnetic wave shield 12 between the conductive layer 14 and the cloth body 10, whereby the electromagnetic wave shield 12 is generated in the conductive layer 14. The propagation of electromagnetic waves to the cloth body 10 side is suppressed. However, in this second embodiment, as shown in FIGS. 4 and 5, the conductive layer 14 and the conductive layer 14 include not only the area directly under the conductive layer 14 but also substantially the entire region where the conductive layer 14 is arranged. An electromagnetic wave shield 12 is formed between the cloth body 10 and the cloth body 10. According to this configuration, the electromagnetic wave shield 12 is formed in a wider range, so that the electromagnetic wave emitted by the conductive layer 14 can be suppressed or blocked more effectively. Further, in the second embodiment, since the electromagnetic wave shield 12 has a wide range, not only the electromagnetic wave emitted by the conductive layer 14 but also the electromagnetic wave from the outside unrelated to the biological information monitoring device of the present invention is suppressed or blocked. can do. In the second embodiment, the electromagnetic wave shield 12 preferably has elasticity so that the sensor 20 can sufficiently exhibit its characteristics. From the viewpoint of comfort, as with the cloth, the pregnant woman who wears the clothes can act naturally and naturally as when wearing a normal pregnant woman's belt, and at the same time, information on the movement of the pregnant woman and the fetal movement of the foetation. It is preferable to have at least 5% or more elasticity so that the like can be detected with high sensitivity. As a method for realizing the elasticity of the electromagnetic wave shield, the method described in the first embodiment can be adopted.

[Third Embodiment]
Next, the pregnant woman band 1 according to the third embodiment will be described with reference to FIG. Since the overall configuration (FIG. 1) may be the same as that of the first embodiment, duplicate description will be omitted below.

In the pregnant woman band 1 of the third embodiment, an electromagnetic wave shield 12 is provided between the conductive layer 14 and the cloth 10 as in the above-described embodiment, so that the electromagnetic waves generated in the conductive layer 14 can be generated. Propagation to the cloth 10 side is suppressed. However, in the third embodiment, the cloth body 10 has a double structure of the first cloth body 10A located on the mother body side and the second cloth body 10B located on the sensor 20 side, and these two pieces. The electromagnetic wave shield 12 is arranged between the

cloth bodies

10A and 10B. In other words, the electromagnetic wave shield 12 of the third embodiment is not in direct contact with the protective layer 13, but is connected to the protective layer 13 via the second cloth body 10B. In FIG. 6, the electromagnetic wave shield 12 has substantially the same end face positions as the protective layer 13, the conductive layer 14, and the protective layer 15 located above the electromagnetic wave shield 12, but as shown in FIG. 3, the electromagnetic wave shield 12 The end face position may be projected, or the electromagnetic wave shield 12 may be formed so as to cover the entire forming region of the conductive layer 14, as shown in FIG.

[Fourth Embodiment]
Next, the pregnant woman band 1 according to the fourth embodiment will be described with reference to FIG. 7. Since the overall configuration (FIG. 1) may be the same as that of the first embodiment, duplicate description will be omitted below.

In the fourth embodiment, as in the above-described embodiment, the electromagnetic wave shield 12 is provided between the conductive layer 14 and the cloth body 10, so that the electromagnetic waves generated in the conductive layer 14 are on the cloth body 10 side. Propagation to is suppressed. However, the electromagnetic wave shield 12 of the fourth embodiment is not formed below all the conductive layers 14, but the electromagnetic wave shield 12 is formed only below a part of the conductive layers 14A, and the rest. Below the conductive layer 14D, the electromagnetic wave shield 12 is not provided below the conductive layer 14D.

The conductive layer 14A is a conductive layer that functions as a sensor 20 as a digital sensor and a wiring layer 40 of the digital sensor. An electromagnetic wave shield 12 is provided below the conductive layer 14A in order to suppress or block electromagnetic waves emitted from the conductive layer 14A.

On the other hand, the conductive layer 14D is a conductive layer that functions as a sensor 20 as an analog sensor (for example, a resistance type strain sensor) or a wiring layer 40 of an analog sensor. In such a conductive layer 14D, electromagnetic waves of the same frequency are not constantly emitted, and the influence thereof is negligible. Therefore, the electromagnetic wave shield 12 is omitted below the conductive layer 14D. That is, in this fourth embodiment, the electromagnetic wave shield 12 is arranged between the digital sensor (second sensor) and the cloth body 10 adjacent to the abdomen of the pregnant woman, but is an analog sensor (first sensor). ) And the cloth 10 adjacent to the abdomen of the pregnant woman.

As described above, in the fourth embodiment, the electromagnetic wave shield 12 is provided only in the portion of the conductive layer 14 that functions as an element that handles digital signals. According to such a configuration, the wearing feeling of the pregnant woman band 1 can be improved by forming the electromagnetic wave shield 12 only at a necessary place. That is, from the viewpoint of comfort, it is possible to enable a pregnant woman who is a wearer of clothes to act naturally without difficulty as when wearing a normal pregnant woman's belt. Further, in the sensor 20 such as the resistance type strain sensor that mainly handles analog signals, since the electromagnetic wave shield 12 is omitted, the fetal movement signal from the mother or the foetation can be detected more directly. The detection accuracy of the sensor can also be improved. The strain sensor converts the deformed state of the surface of the mother body into an electric signal and outputs it. Since the strain sensor is generally unaffected by the movement of the center of gravity of the pregnant woman, it is suitable for monitoring the biological signals of the foetation and / or the pregnant woman.

Further, the sensor 20 as an analog sensor (for example, a resistance type strain sensor) or the conductive layer 14D functioning as the wiring layer 40 of the analog sensor generally functions as a substantial electromagnetic wave shield against electromagnetic waves. Therefore, by installing the conductive layer 14D, it is possible to suppress or block electromagnetic waves from the outside, which are unrelated to the biological information monitoring device of the present invention, without installing another electromagnetic wave shield 12 under the conductive layer 14D. ..

[Fifth Embodiment]
Next, the pregnant woman band 1 according to the fifth embodiment will be described with reference to FIG. The pregnant woman band 1 of the fifth embodiment is also configured by arranging the sensor 20, the control unit 30, and the wiring layer 40 on the cloth body 10 as in the above-described embodiment. Further, the same as the above-described embodiment, the electromagnetic wave shield 12 is provided between the conductive layer 14 that functions as the sensor 20 or the wiring layer 40, the control unit 30, and the cloth body 10. FIG. 8 shows an example of a wiring structure when a resistance type analog sensor is selected as the sensor 20 and a circuit for measuring the resistance value of the resistance type analog sensor, for example, a voltage dividing circuit, is installed in the control unit 30. Although shown, it is not particularly limited to this.
