Description

Elastic clothing with conductive parts

The present invention relates to a “stretchable garment having a conductive portion” and a “clothing for biometric data acquisition” and a “clothing having a permeable conductive portion”.

An elastic garment that can be used for collecting biological data used for electrocardiograms, electromyograms, etc., or performing electrical therapy or electromagnetic wave therapy has been proposed (see Patent Document 1). In this elastic garment, the conductive fiber is knitted into an elastic fabric by float knitting, so that the exposed amount of the conductive fiber on the back side (the side in contact with the wearer's skin surface) is larger than the exposed amount on the front side. It is a configuration. That is, the electrode which contacts a wearer is formed by the conductive fiber exposed on the back side of the elastic fabric.

Also, it has been proposed that positive and negative electrodes that can contact the skin surface of the wearer are attached to the clothing in an arrangement separated from each other (see Patent Document 2). These electrodes have a structure that can be mechanically engaged and disengaged with a connector part (a terminal for detection) of a terminal device used for collecting data such as an electrocardiogram. The detection device can be attached and detached.

By the way, in the electrode apparatus which can be used for collection of biometric data or the like, it has been proposed to provide a water retaining member between the electrode and the skin surface (see Patent Document 3).
In addition, water is absorbed by an electrode formed of a porous and conductive material, and biological data is collected by interposing the water-absorbed electrode inside the clothing (the side facing the skin surface of the wearer). Has also been proposed (see Patent Document 4).

Japanese Patent No. 4609923 Japanese Patent Laying-Open No. 2015-77270 Japanese Utility Model Publication No. 4-27902 JP 2014-226367 A

If an electrode is to be formed on a cloth such as an elastic cloth like the elastic clothes shown in Patent Document 1, conductive fibers that are harder than synthetic fibers and natural fibers must be used. For this reason, there has been a difficulty that it is difficult to bring this electrode into surface contact with a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. That is, part or all of the electrodes may be out of contact with the skin surface (raised). Naturally, when the wearer performs an action such as exercise, not only surface contact but also reliable and continuous contact is difficult to obtain.

In addition, in the elastic clothing of Patent Document 1, the strength of “elasticity”, which is an essential requirement, is “elastic stockings (unlike general-purpose stockings, which intentionally compresses the skin surface” as a representative embodiment. It is a considerably strong tightening force so that it can be easily inferred from the fact that "medical products with strong tightening force" are listed. In other words, the requirement for such a limited requirement can be said to be proof that the lifting of the electrode exists as a potential problem when it is assumed to be applied to general-purpose clothing.

On the other hand, in the proposed technique shown in Patent Document 2, since the wearing state of the detection device with respect to the clothing is all left to the positive and negative electrodes provided directly on the clothing, the fixing force of the detection device with respect to the wearer of the clothing is almost constant. It goes without saying that you cannot get it. For this reason, if the wearer moves, the detection device easily shifts in position with respect to the wearer, resulting in a fundamental problem that correct measurement cannot be performed when collecting data such as an electrocardiogram.

The technology disclosed in Patent Literature 1 and the technology disclosed in Patent Literature 2 are fundamentally different in technical idea, and cannot be solved by any of the disclosed technologies (for example, fixing of a detection device). There are a lot of things to improve.
By the way, in the elastic garment shown in Patent Document 1, since the electrode is formed of a knitted structure, innumerable small irregularities due to fibers are generated on the electrode surface. For this reason, when the wearer wears this elastic garment, even if the electrode and the skin surface of the wearer appear to be in surface contact, there are innumerable minute gaps when observed microscopically. I can say.

As a result, the contact area between the electrode and the skin surface decreased, and the tendency to increase electrical resistance could not be eliminated. In particular, in an environment where humidity is low (air is dry), this becomes a bottleneck, and in order to perform highly accurate measurement when collecting biological data, the surface area of the electrode is increased (the electrode is There is a need to increase the apparent contact area with the skin surface.
However, there is a limit to increasing the surface area of the electrode. Even if the surface area of the electrode can be increased as much as possible, the conductive fibers forming the electrodes are harder than synthetic fibers and natural fibers. It is difficult to produce high adhesion to a target and complicated curved surface, unevenness, and flexible part, and it is also difficult to reduce the electrical resistance between the electrode and the skin surface.

Therefore, there is a problem that it is difficult to obtain a highly accurate measurement result when collecting biological data, and there is a problem that an unpleasant sensation due to electrical stimulation (such as tingling tingling) may occur during electrotherapy.
On the other hand, the effect of reducing the electrical resistance between the electrode and the skin surface can be expected theoretically by wetting the electrode device with water as in Patent Documents 3 and 4. However, in actuality, it must be said that none of the proposed technologies lacks practicality.

This is because, in the proposed technique shown in Patent Document 3, when the electrode is strongly pressed toward the skin surface, a large amount of water is released from the water retaining material interposed between the electrode and the skin surface. That is, it has a big problem in use that the surroundings as well as clothes and skin surface get wet. Not only that, water in the water retaining material enhances conductivity, but the contact pressure between the electrode and the water retaining material and the contact pressure between the water retaining material and the skin surface must be maintained at a predetermined pressure. It is necessary to press toward the skin surface. In this way, it can be pointed out that this proposed technique has a contradictory problem.

Further, in the proposed technique shown in Patent Document 4, since the electrode itself is water-absorbing and contains water abundantly, the electrode is strongly pressed toward the skin surface as in Patent Document 3. Occasionally, there is a problem that clothes, skin surfaces, and surroundings get wet with water.
Moreover, since it is necessary to connect an electrical contact to an electrode containing abundant water, it is troublesome to attach and detach the electrode to and from clothes, and it is also included in the electrode during this attachment and detachment. There was a high risk of splashing water around. That is, not only the problem of water wetting, but also the problem of inviting a critical water shortage when using the electrode.

The present invention has been made in view of the above circumstances, and even when implemented as a general-purpose garment, the conductive surface can be brought into surface contact with the skin surface, and the skin surface is static or moving. It is a first object of the present invention to provide a stretchable garment provided with a conductive portion that enables a surface contact state to be maintained without being affected by whether or not it is the target.
In addition, the present invention achieves the first object, and further enables simple attachment / detachment of the detection device and reliable fixation to the wearer at the time of wearing (reliable measurement by the detection device is possible even if the wearer moves). A second object is to provide a biometric data acquisition garment that can be used.

Furthermore, the present invention reduces the electrical resistance between the electrode and the skin surface without using other measures such as an increase in the size of the electrode when taking it for biological data collection or electrical therapy. Therefore, it is possible to eliminate problems such as difficulty in obtaining high-precision measurement results when collecting biological data and problems that may cause discomfort due to electrical stimulation (stinging) during electrotherapy. A third object is to provide a garment having a conductive portion.

Means adopted by the present invention to achieve the first object are as follows.
That is, the stretchable garment provided with the conductive portion according to the present invention includes a body fabric body that is sufficiently stretchable to follow and recover the movement of the wearer, and the body surface of the body fabric to the wearer's skin surface. A conductive portion provided with a conductive surface in a facing direction, and the conductive portion is covered with a covering portion on a surface that is opposite to the conductive surface, and the covering portion is covered with clothing. It is characterized by being provided integrally or separately with the body fabric body in a state where the conductive portion is elastically pressed against the skin surface of the wearer following the expansion of the body fabric body.

The conductive portion can be formed by weaving the body body.
The conductive portion may be formed in a sheet shape different from the body cloth body and attached to the body cloth body.
The body fabric body has a weak elasticity that does not hinder the movement of the wearer in the vertical stretch among the stretchability that causes the vertical stretch in the height direction of the wearer and the horizontal stretch in the waist direction of the wearer. It is preferable to have a resistance, and to stretch and stretch the body body perfectly to the wearer, to develop a strong clamping force with a strong elastic resistance for preventing slippage and to increase the pressure on the skin surface.

That is, when the wearer wears the body, the Y direction (height direction) has a small elastic resistance and easily expands and contracts following the movement of the body, while the elastic resistance is large and hardly stretched in the X direction (trunk direction). It is preferable that the cloth main body is pressed in the Z direction (body) as a result.
The covering portion can be provided by forming an article accommodating portion between the conductive portion and an opening that allows the article to be taken in and out of the outer peripheral portion of the article accommodating portion.

The covering portion may be provided with a pressing pad having an increased thickness in an arrangement that matches the conductive portion.
The conductive portion may be provided with a non-slip material toward the wearer at the outer peripheral portion of the conductive surface.
The body cloth main body may be provided with a ventilation portion that penetrates between a surface facing the skin surface of the wearer and an outer surface.

Means employed by the present invention to achieve the second object are as follows.
That is, the garment for acquiring biometric data according to the present invention has a body fabric body that is elastic enough to stretch and recover following the movement of the wearer, and the skin surface of the wearer with respect to the body fabric body. A conductive portion provided in an arrangement facing the conductive surface, and a device mounting portion that holds the detection device for acquiring biometric data from the wearer in the body main body in a state of being electrically connected to the conductive portion, The body cloth main body is provided with a pressing biasing portion that presses the conductive portion and the detection device held by the device mounting portion in a mutual contact direction, and the pressing biasing portion is It is characterized by having an urging force that enables the conductive portion and the detection device to be pressed even at the maximum extension caused by the movement of the wearer within the schedule.

When the direction surrounding the torso, leg, arm, or neck of the wearer is set as the horizontal direction, the conductive surface of the conductive portion is a size obtained by expanding the contact area of the detection contact included in the detection device at least in the horizontal direction. It is preferable to have a thickness.
The conductive portion may be disposed inside the device mounting portion in the middle, and the pressing biasing portion may be disposed outside the device mounting portion.

Alternatively, the conductive portion is disposed inside the device mounting portion in the middle, and the body cloth main body is disposed outside the device mounting portion. The conductive portion may also serve as the pressing biasing portion by providing a biasing force that enables the conductive portion to be pressed against the detection device even at the maximum extension caused by the movement of the.

The device mounting portion may include a spacer member that restricts movement of the detection device by abutting against a facing side surface of the detection device.
The body cloth main body may be provided with a loading / unloading port that allows the detection device to be attached to and detached from the device mounting portion from the opposite side to the side facing the skin surface of the wearer.
Means employed by the present invention to achieve the third object are as follows.

That is, a garment having a water permeable conductive portion according to the present invention has a body cloth body and a conductive portion provided in an arrangement facing the body surface of the wearer with respect to the body cloth body, The part is formed to have a skin contact surface that comes into contact with the skin surface of the wearer and an exposed back surface that is a surface opposite to the skin contact surface, and between the skin contact surface and the exposed back surface. It is characterized by being provided with water permeability.

The conductive portion is preferably formed with a fiber structure made of conductive yarn.
It is preferable that the body main body is provided with a pressing and urging portion that presses the exposed back surface of the conductive portion toward the skin surface of the wearer.
A container for holding a water supply material for continuously supplying water or a coolant for causing condensation is provided between the conductive portion and the pressing biasing portion in the body cloth body. It is good to do. It is more preferable that the water supply material or the coolant is held in the housing portion in a detachable manner.

The housing portion is preferably formed in a pocket shape that surrounds the outer periphery 3 of the water supply material or the coolant.
The body cloth main body may be provided with a waterproof portion that covers the back of the housing portion.
The body cloth main body may be provided with an access port that allows the water supply material or the cooling material to be detachable from behind the housing portion.

In addition to the body cloth main body and the conductive portion, a water supply material for continuously supplying water to the conductive portion or a coolant for causing condensation may be provided.
The water supply material or the coolant may be provided with a water stop portion on a surface opposite to the surface facing the conductive portion.
The water supply material or the coolant may be formed of a porous material.

In addition, this porous material should be able to flexibly adapt to the irregularities caused by the skeleton of the human body or the flesh of the elastic body (for example, a porous body or a knit structure having elasticity in the thickness direction). Therefore, it can be said that it is preferable. Such a porous material may be employed as a material for forming the water stop portion.
A moisture adjusting unit may be provided between the conductive unit and the water supply material or the coolant.

The stretchable garment including the conductive portion according to the present invention can bring the conductive surface into surface contact with the skin surface even when implemented as a general-purpose garment, and the skin surface is static or dynamic. It is possible to maintain the surface contact state without being affected by the presence.
In addition, in the garment for obtaining biometric data according to the present invention, in addition to the effect that surface contact is possible and can be maintained, the detection device can be easily attached and detached and securely fixed to the wearer at the time of wearing (clothing). (Even if the person moves, reliable measurement can be performed by the detection device).

On the other hand, a garment having a water-permeable conductive portion according to the present invention can be used for collecting biological data without taking measures such as increasing the size of the electrode when taking it for biometric data collection or electrotherapy. The electrical resistance between the skin and the skin surface can be reduced, so it is difficult to obtain high-precision measurement results when collecting biometric data, and there is a risk of discomfort due to electrical stimulation (stinging) during electrotherapy. The problem of being there can be wiped out.

In addition, the increase in the size of the electrode leads to a problem that it is difficult to accurately acquire the electrocardiogram due to, for example, collecting even unnecessary myoelectricity when collecting the electrocardiogram. Since it can be rejected, it is also beneficial to eliminate such problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a “stretchable garment having a conductive portion” according to the present invention will be described below with reference to the drawings.
FIG.1 and FIG.2 has shown 1st Embodiment of the elastic clothing 1 (henceforth "the clothing 1 of this invention") provided with the electroconductive part which concerns on this invention. As is apparent from FIGS. 1 and 2, the garment 1 of the present invention has a conductive portion 3 that can be electrically connected to the wearer as a part of the body fabric body 2 or a separate body. The basic configuration is that it is provided.

The conductive portion 3 is covered with a covering portion 4, and the conductive portion 3 is pressed against the wearer of the garment 1 (clothing body 2) by the covering portion 4.
First, the outline will be described. In principle, the body body 2 is formed of a non-conductive fiber material (at least the insulating region centered on the arrangement portion of the conductive portion 3). On the other hand, the conductive part 3 is formed using conductive yarn, and at least the surface directed to the skin surface of the wearer is formed as a conductive surface 3a having conductivity. In addition, a wiring part for the conductive part 3 may be formed in the body cloth body 2.

With respect to such a conductive portion 3, the covering portion 4 is arranged so as to cover a surface opposite to the conductive surface 3a. Therefore, the conductive surface 3a of the conductive portion 3 is exposed to the skin surface of the wearer, and the wearer wears the garment 1 (cloth body body 2) of the present invention. 3a comes into contact with the skin surface of the wearer.
Thus, various measuring devices for collecting electrocardiograms, electromyograms, etc. were connected to the conductive part 3, or treatment devices for performing electrotherapy, electromagnetic wave treatment, etc. were connected to suit each purpose of use. How to use can be adopted.

In this 1st Embodiment, the case where the body fabric main body 2 is made into the T-shirt type upper garment is shown. That is, the body fabric body 2 forms left and right sleeves with respect to a seamless tubular fabric in the circumferential direction, and opens a collar on one side in the tube axis direction ([Ariaki]: a hole through which the head of the wearer passes. ).
Further, in the first embodiment, a case is shown in which the conductive portion 3 is arranged corresponding to two upper and lower portions placed on the chest to abdomen of the wearer. The conductive portions 3 are knitted integrally with the body main body 2 in a limited area.

Further, in the first embodiment, the covering portion 4 formed of a fabric different from the body fabric body 2 is provided so as to surround the entire outer periphery of the body fabric body 2 including the conductive portion 3. . In FIG. 2, it is drawn in a state where there is a gap between the conductive portion 3 and the covering portion 4 (a state of being separated), and the body fabric body 2 and the covering portion 4 are other than the region where this gap exists. It shall be joined only with. The circumferential stretchability of the covering portion 4 is set to be smaller (tightening force is stronger) than the circumferential stretchability of the body fabric body 2.

Therefore, when the garment 1 of the present invention is worn, the covering portion 4 generates a stronger tightening force on the wearer than the body cloth body 2, and the covering portion 4 reliably applies back pressure to the conductive portion 3. As a result, a situation is obtained in which the conductive portion 3 is in surface contact with the wearer.
Thus, by providing a gap between the conductive portion 3 and the covering portion 4, the covering portion 4 has an unnecessary contracting force with respect to the conductive portion 3 when the garment 1 of the present invention is not used (not worn). Thus, there is an advantage that the conductive portion 3 can be prevented from being deformed or defective in conductivity. However, such a gap between the conductive portion 3 and the covering portion 4 is not indispensable, and the covering portion 4 is joined to the body cloth body 2 around the entire circumference including the conductive portion 3. May be.

Appropriate methods such as adhesion with an adhesive, thermal fusion with a thermoplastic resin, sewing with a sewing machine, engagement with a hook-and-loop fastener, etc. can be adopted as a method of joining the body body 2 and the covering portion 4. is there. Further, when the covering portion 4 is joined to the body cloth body 2 around the entire circumference including the conductive portion 3, the body cloth body 2 and the covering portion 4 can be knitted as a double cloth.
Next, the body body 2 will be described in detail. The body fabric body 2 can be knitted using a non-conductive fiber material as described above. Specific examples of the fiber material include synthetic fiber (for example, polyester fiber and nylon fiber), natural fiber, and a material obtained by mixing synthetic fiber and elastic yarn.

Also, the knitting structure adopted for the body fabric body 2 is not limited at all. For example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, a Milan rib or a cardboard knit) can be employed. Naturally, for knitting, not only a circular knitting machine but also a flat knitting machine can be used. In addition, the organization knitted by the weft knitting as listed above may be a knitting organization (tricot knitting, Raschel knitting, Miranese knitting, etc.) knitting by warp knitting.

When knitting the body 2, the elastic yarn is further mixed so that abundant expansion and contraction can be obtained in the direction of expanding and contracting the cylinder diameter (peripheral length) and the cylinder shaft length. This is suitable for fixing the mounting position and facilitating removal.
Here, the “elastic yarn” maintains a contracted state when no tensile force is applied (non-extension = normal state), and freely expands according to the tensile force when a tensile force is applied, and When the tensile force is released and the load is restored when no load is applied, the material is restored (contracted) from the stretched state to the original contracted state.

As a method for mixing elastic yarns, a form selected from at least one of inlay, drawing, plating, knit, or composite yarn may be adopted. For elastic yarn, polyurethane or rubber-based elastomer material may be used alone, or covering yarn using polyurethane or rubber-based elastomer material for “core” and nylon or polyester for “cover” can do. By employing such covering yarn, functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring can be imparted to the garment 1 of the present invention. It is also useful for improving the feel (feel) and controlling elongation.

The body fabric body 2 knitted and knitted in this way has elasticity so as to sufficiently follow and recover the movement of the wearer. The stretchability of the body fabric body 2 is such that when the longitudinal stretch along the height direction of the wearer and the lateral stretch along the waistline direction of the wearer are caused, the vertical stretch may hinder the movement of the wearer. It has a weak elastic resistance to the extent that the body fabric body 2 is perfectly fitted to the wearer in the horizontal expansion and contraction, and a strong elastic resistance to prevent slippage and a strong tightening force are exerted to increase the pressure on the skin surface. Those are preferred.

That is, when the wearer wears the body, the Y direction (height direction) has a small elastic resistance and easily expands and contracts following the movement of the body, while the elastic resistance is large and hardly stretched in the X direction (trunk direction). It is preferable that the cloth main body 2 is pressed in the Z direction (body) as a result.
As described above, as a specific knitting method for knitting a cylindrical fabric that has a strong clamping force because it is relatively easy to stretch in the Y direction and difficult to stretch in the X direction, and presses the body fabric body 2 in the Z direction. For example, as a method of adopting a knitting structure of a milling knitting inlay, a method of performing milling knitting with a covering yarn using polyurethane 22 dtex equivalent and inlaying about 110 dtex of polyurethane as an insertion yarn can be mentioned.

Next, the conductive part 3 will be described in detail. The conductive yarn forming the conductive portion 3 is formed of a metal strand, a metal-coated wire, carbon fiber, or the like.
As specific examples of the metal component in the metal strand or the metal-coated wire, gold, platinum, silver, copper, nickel, chromium, iron, copper, zinc, aluminum, tungsten, stainless steel and the like are suitable. In addition, pure metals such as titanium, magnesium, tin, vanadium, cobalt, molybdenum, tantalum, and alloys thereof (brass, nichrome, etc.) can be used.

As the metal strand, not only a continuous long wire but also a twisted single wire can be used. On the other hand, when the core material is a resin fiber, wire or animal or plant fiber in a metal-coated wire, a wet coating method or a powder adhesion method can be used, including plating treatment employed in resin plating methods, etc. Good. Further, when the core material is a metal wire, a thermal spraying method, a sputtering method, a CVD method, or the like can be employed. Monofilaments, multifilaments, and spun (spun) yarns may be used as the core material, or wooly processed yarns, covering yarns such as SCY and DCY, and bulky processed yarns such as fluffed yarns may be used.

In addition, these metal wires, metal-coated wires, and carbon fibers may be mixed with non-conductive fibers. For example, a spun (spun) yarn can be used for blended yarn, covering yarn, or assortment. It is also possible to mix with a fiber having a melting point and a softening point higher than the heat setting temperature.
As the knitting structure used for the conductive surface 3a, for example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, Milan rib, corrugated cardboard knit, Kanoko, pile, etc.) can be adopted. These knitting structures are knitted by cut boss knitting during the knitting of the main body 2.

In some cases, it is also possible to employ a structure in which the ground yarn portion serving as the basis of the conductive portion 3 is knitted as a full knit of the above-mentioned various knitting structures and knitted by float knitting on the conductive surface 3a side of the same region. In this case, the float yarn of the float knitting rises beyond the height in the thickness direction due to the knitting structure of the ground yarn. Therefore, the contact of the conductive surface 3a is further ensured with respect to a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. In addition, it will follow even more precise movements of the skin surface. Therefore, reliable conductivity can be obtained.

Next, the covering portion 4 will be described. Basically, the fiber material and the knitting structure forming the covering portion 4 can be appropriately selected within the above-described range with respect to the body body 2. However, a strong tightening force (tightening force) at least in the circumferential direction is obtained in relation to the stretchability set in the body cloth body 2.
As for the stretchability of the covering portion 4, as in the case of the body body 2, the stretchable portion has a weak elastic resistance that does not hinder the movement of the wearer in the vertical expansion and contraction. It is preferable to have a strong elastic force for perfectly fitting the wearer and preventing the slippage and exhibiting a strong tightening force and increasing the pressure on the skin surface.

As described above, as apparent from the detailed description, when the wearer wears the garment 1 of the present invention, the covering portion 4 surely applies back pressure to the conductive portion 3, and as a result, the conductive portion The conductive surface 3a of the part 3 is surely brought into surface contact with the skin surface of the wearer. Therefore, it can be implemented as a general-purpose garment (other than medical use having a strong tightening force enough to intentionally press the skin surface). Of course, it is needless to say that medical implementation is possible.

Moreover, even when implemented as general-purpose clothing, it is possible to maintain a surface contact state without being affected by whether the skin surface is static or dynamic. Therefore, when collecting data such as an electrocardiogram and an electromyogram, a current waveform can be satisfactorily extracted from the conductive surface 3a in contact with the skin surface of the wearer via the conductive surface 3a, and electrotherapy is performed. When conducting electromagnetic wave treatment or the like, a current can be favorably applied from the conductive surface 3a to the skin surface of the wearer via the conductive surface 3a.

3 and 4 show a second embodiment of the garment 1 of the present invention. The second embodiment is different from the first embodiment in that a covering portion 4 is provided on the inner peripheral surface side of the body cloth body 2. Further, the conductive portion 3 is not directly provided on the body cloth body 2 but is provided on the inner surface side of the covering portion 4 so as to have an indirect relationship with the body cloth body 2. This point is also different from the first embodiment.

Other configurations and operational effects are substantially the same as those of the first embodiment, and detailed description thereof is omitted here. Note that the various embodiments described below are also described mainly for the significant differences from the first embodiment or the second embodiment, and have the same contents as the configurations and operational effects described in the first embodiment. Description is omitted.
FIG. 5A shows a third embodiment of the garment 1 of the present invention. In this 3rd Embodiment, the coating | coated part 4 shown in 1st Embodiment is provided so that it may cover not only the perimeter of the cloth body main body 2, but the limited range containing the electroconductive part 3. FIG. This is different from the first embodiment.

FIG. 5B shows a fourth embodiment of the garment 1 of the present invention. In this 4th Embodiment, the coating | coated part 4 shown in 1st Embodiment is provided in the state which formed the pocket-shaped article accommodating part 7 between the electrically conductive parts 3 by the arrangement | positioning facing the electrically conductive part 3. This is different from the first embodiment.
An opening 8 that allows the article to be taken in and out is formed on the outer peripheral portion of the article accommodating portion 7, and an appropriate back pressure member (not shown) can be accommodated through the opening 8. In addition, the position where the opening 8 is provided in the article storage unit 7 may be the upper side, the left and right sides, or the lower side in some cases, or when the article storage unit 7 has a shape having no directionality such as a circle, It can be anywhere in the department.

As the back pressure member accommodated in the article accommodating portion 7, cloth such as towels, cotton, shredder waste, foamed polystyrene, sponge, rubber, silicon, urethane, air bags, gel encapsulated bags, and the like can be appropriately employed.
Thus, by providing the article accommodating portion 7 in which the back pressure member can be freely inserted and removed, the type and amount of the back pressure member can be changed according to the body shape of the wearer, and the optimal pressing state of the conductive portion 3 can be achieved. The advantage is that it can be adjusted.

In the fourth embodiment, the covering portion 4 is illustrated as being provided only in a range that does not reach the entire circumference of the body cloth body 2 as in the third embodiment, but as indicated by a two-dot chain line, You may make it provide over the perimeter of the body fabric main body 2. FIG.
FIG. 5C shows a fifth embodiment of the garment 1 of the present invention. The fifth embodiment is different from the first embodiment in that the article accommodating portion 7 is formed in the covering portion 4 and the padding 9 is enclosed in the article accommodating portion 7 (not removable). ing.

Since it is not assumed that the padding 9 is put in and out of the article storage part 7 (there is no equivalent to the opening 8 of the fourth embodiment), the pressing force of the conductive part 3 can be made constant and the padding 9 can be prevented from being lost. Advantages such as being able to be obtained.
FIG. 5D shows a sixth embodiment of the garment 1 of the present invention. The sixth embodiment is different from the first embodiment in that an article accommodating portion 7 is formed in the covering portion 4 and an opening 8 is formed in the article accommodating portion 7. Although it is substantially the same as 4th Embodiment, in this 6th Embodiment, it is assumed that the articles | goods accommodating part 7 planned accommodation of the device apparatus 10, and the electroconductive part 3 is arrangement | positioning or arrangement | positioning in the electrode which the device apparatus 10 has. It differs from the fourth embodiment in that the numbers are combined.

That is, in the sixth embodiment, the device device 10 is accommodated in the article accommodating portion 7 so that the electrode of the device device 10 comes into direct contact with the skin surface of the wearer via the conductive portion 3. Therefore, there is an advantage that measures such as wiring for the conductive portion 3 are not required in the body cloth main body 2 and the covering portion 4.
FIG. 5E shows a seventh embodiment of the garment 1 of the present invention. The seventh embodiment is different from the first embodiment in that a pressing pad 12 having an increased thickness with an arrangement that matches the conductive portion 3 is provided for the covering portion 4.

The pressing pad 12 is formed in a flat shape so that the surface facing the conductive portion 3 is compatible with the conductive portion 3, and has a shape that bulges toward the opposite side of the flat surface. Note that the pressing pad 12 and the conductive portion 3 may be brought into contact with each other or non-contacted (a gap may be generated). Moreover, when making it contact, it is good also as a joining state, and good also as a non-joining state.
The pressing pad 12 can be provided integrally with the covering portion 4 or can be provided later as a separate product. The material for forming the pressing pad 12 may be silicon rubber or urethane rubber. Moreover, in the coating | coated part 4, the position which provides the press pad 12 is formed in a bag shape, and the press pad 12 can also be formed by carrying out appropriate padding in this bag.

By providing such a pressure pad 12, the stretchability of the portion corresponding to the conductive portion 3 in the covering portion 4 can be further reduced, and the hardness of the portion that presses the conductive portion 3 can be increased. From these things, the advantage which can press the electroconductive part 3 to a wearer's skin surface firmly is acquired.
FIG. 5F shows an eighth embodiment of the garment 1 of the present invention. The eighth embodiment is different from the first embodiment in that a pressing pad 12 having an increased thickness is provided for the covering portion 4 so as to match the conductive portion 3. Although it is substantially the same as 7th Embodiment, in this 8th Embodiment, the press pad 12 is formed in the shape which bulges toward the electroconductive part 3, and is different from 7th Embodiment by this point. .

Since the pressing pad 12 has a shape that bulges toward the conductive portion 3, the covering portion 4 can easily obtain a situation where both sides of the pressing pad 12 are separated from the body fabric body 2 and become a cross-linked shape. Therefore, in the eighth embodiment, there is an advantage that it is easy to adjust the back pressure applied to the conductive portion 3 by the pressing pad 12 during clothing.
Therefore, it is possible to soften the contact pressure of the conductive portion 3 against the skin surface of the wearer. On the contrary, since the pressing to the conductive portion 3 by the pressing pad 12 can be made into a high surface pressure contact, this leads to advantages such as enhancing the effect of preventing the displacement of the conductive portion 3 with respect to the wearer.

In addition, although illustration is abbreviate | omitted, when the press pad 12 of this 8th Embodiment is combinedly implemented by the goods accommodating part 7 of 6th Embodiment, the situation where the device apparatus 10 sinks into this press pad 12 is carried out. I can make it. Therefore, in this case, it is effective for preventing the positional deviation of the device apparatus 10.
FIG. 6A shows a ninth embodiment of the garment 1 of the present invention. In the ninth embodiment, the conductive portion 3 formed in a sheet form different from the body fabric body 2 is bonded or sewn to the inner peripheral surface side (the side facing the skin surface of the wearer) of the body fabric body 2. It is different from the first embodiment in that it is attached by wearing.

Although the covering portion 4 is illustrated as being provided only in a range that does not reach the entire circumference of the body cloth body 2, it may be provided over the entire circumference of the body cloth body 2 as indicated by a two-dot chain line. Good.
The conductive portion 3 shown in the ninth embodiment is formed into a sheet form by knitting with a conductive yarn. In such a case, since the yarn end of the conductive yarn appears on the outer peripheral portion of the conductive portion 3, the outer peripheral portion of the conductive portion 3 is subjected to a fraying prevention process using a heat fusion material or a heat bonding material. It is preferable to keep it.

This fraying prevention process is a process of fixing the portion where the conductive yarn used for forming the conductive portion 3 intersects in the knitting structure, and by applying this fraying prevention process, the yarn end of the conductive yarn is Prevents floating. That is, since the fraying prevention process is performed, the conductive portion 3 is formed in one piece (substantially flat state) in conformity with the body cloth body 2 without the side portion of the outer peripheral portion being lifted up strangely. .

The fraying prevention method is carried out by mixing at least one of a heat-seal material or a heat-seal material with the conductive yarn used for forming the conductive part 3, and then knitting the conductive part 3, followed by heat setting after knitting. The procedure is to perform.
The difference between the heat-sealing material and the heat-sealing material may be distinguished by the strength of the bonding force generated by cooling from the semi-molten state. A material having a weaker binding force (fusing) than that is a heat fusing material. Although this distinction is not clear and includes an ambiguous portion, the point is that in the present invention, any material can be used as long as the crossing portions of the conductive yarns can be joined by heat setting. Accordingly, a material that has excellent stretchability (elasticity), is heat-sealed by heating, and retains high stretchability (elasticity) without losing stretchability (elasticity) at the heat-sealed portion. be able to.

Specifically, a low melting point polyurethane can be given as a representative example of the heat-sealing material or the heat-sealing material. Low melting point polyurethane is an optimal example. In addition, a condensation polymer such as polyethylene, nylon (nylon 6 or nylon 66), polypropylene, polyvinyl chloride, vinyl polymer, polyamide, or the like can be used.
Further specific examples include low melting point polyamide fiber yarns, low melting point polyester fiber yarns (low melting point polyester copolymer fiber yarns, low melting point aliphatic polyester fiber yarns) and the like. Of these, low melting point polyester fiber yarns are preferred.

Preferred copolymer components of the low melting point polyester copolymer constituting the low melting point polyester copolymer fiber yarn include glycolic acid, 3-hydroxybutyric acid, 4-hydroxybutyric acid, 4-hydroxyvaleric acid, and 6-hydroxycaproic acid. In addition to hydroxycarboxylic acids such as ethylene glycol, propylene glycol, butanediol, neopentyl glycol, polyethylene glycol, glycerin, pentaerythritol, etc. In the molecule such as acid, fumaric acid, terephthalic acid, isophthalic acid, 2,6-naphthalenedicarboxylic acid, 5-sodium sulfoisophthalic acid, 5-tetrabutylphosphonium isophthalic acid, 5-tetrabutylphosphonium isophthalic acid Compounds or derivatives thereof containing the number of the carboxylic acid group.

Examples of the low melting point aliphatic polyester constituting the low melting point aliphatic polyester fiber yarn include polylactic acid, polyglycolic acid, poly-3-hydroxypropionate, poly-3-hydroxybutyrate, and poly-3. -Hydroxybutyrate valerate, polycaprolactone and the like.
Other commercially available heat-fusible fiber yarns include low-melting polyamide fiber yarns that melt with dry heat of 80 to 130 ° C. or wet heat of 50 to 100 ° C., such as Flor (manufactured by Unitika), Elder (Toray Industries, Inc.), Joiner (Fujibo), etc. can be used.

Also, low-melting polyester fiber yarns that melt with dry heat of 80 to 130 ° C. or wet heat of 50 to 100 ° C., such as Sophit (Kuraray), Melty (Unitika), Solstar (Mitsubishi Rayon), Bel combi (manufactured by Kanebo Co., Ltd.), estenaal (manufactured by Toyobo Co., Ltd.), etc. may be used.
As means for heat-sealing the heat-fusible fiber yarn by heat treatment, heat treatment by wet heat or dry heat is used. Examples of the wet heat treatment include treatment with hot liquid such as steam, hot water, and dye bath. Examples of the dry heat treatment include a heat treatment such as hot air drying.

In the case of performing an in-bath process such as scouring, dyeing, and soaping, heat fusion by wet heat treatment is possible in the bath, which is preferable because the process can be reduced. In this case, the heat treatment temperature has a preferred lower limit of 50 ° C. and a preferred upper limit of 100 ° C. A more preferred lower limit is 60 ° C., and a more preferred lower limit is 65 ° C.
In the method of mixing the heat-sealable material or heat-sealable material with the conductive yarn, the conductive yarn is the “core” and the heat-sealable material yarn or the heat-sealable material yarn is the “cover”. There are a method of using a covering yarn (which may be SCY or DCY), a method of aligning a yarn made of a heat-fusion material or a yarn made of a heat-bonding material to a conductive yarn (may or may not be a plating knitting), and the like. .

In the heat setting, the intersecting portions of the conductive yarns are joined together due to the fact that the heated heat-sealable material causes heat-seal or the heat-sealable material causes coalescence. In this case, the conductive yarn after heat setting is required to have a conductive component exposed on part or all of the yarn surface. Therefore, the exposed portion of the conductive yarn is generated by appropriately adjusting the thickness and amount (number) of yarns made of heat-fusion material or yarns made of heat-fusion material, and the heating temperature when performing heat setting. Like that.

By performing such fraying prevention treatment, the conductive portion 3 is prevented from being caught by the yarn end because the yarn end of the conductive yarn does not float in the side portion of the outer peripheral portion. It will lead to a fraying prevention effect. In addition, the anti-fraying effect can be obtained, so that the extension of the yarn end can be cut as short as possible. As a result, itching and pain when touching the skin surface are suppressed as much as possible. It will be possible. In addition, since the intersections of the conductive yarns are covered by the adhesion of the heat-seal material or heat-seal material, the feeling of contact with the skin is alleviated and slippage is improved, improving the feel of the skin. To be helpful.

FIG. 6B shows a tenth embodiment of the garment 1 of the present invention. The tenth embodiment is different from the first embodiment in that a conductive portion 3 formed in a sheet form is attached to the inner peripheral surface side of the body cloth body 2. Although substantially the same as the ninth embodiment, in the tenth embodiment, the conductive portion 3 is formed by weaving into a fabric 15 knitted separately from the body fabric body 2, and the covering portion 4 is It differs from the ninth embodiment in that it is provided so as to surround the entire outer periphery of the dough body 2.

Note that the fabric 15 in which the conductive portion 3 is knitted is attached to the body fabric body 2 by adhesion or sewing. Accordingly, the body cloth main body 2 can be formed with an unconnected portion 16 such as an opening or a cut in a region overlapping the conductive portion 3. In other words, the body fabric body 2 is not necessarily limited to a seamless cylindrical fabric in the circumferential direction, and is structured to be connected in a tubular shape via the attachment portion (fabric 15) of the conductive portion 3. It will be good.

FIG. 6C shows an eleventh embodiment of the garment 1 of the present invention. The eleventh embodiment can be said to be a composite implementation of the ninth embodiment and the tenth embodiment. That is, the conductive portion 3 is formed in a sheet shape whose outer peripheral portion is subjected to fraying prevention treatment, and is attached to the inner peripheral surface side of the body fabric body 2 by bonding or sewing. It is provided so as to surround the entire outer periphery of the dough body 2.

Further, the body fabric body 2 has a structure in which an unconnected portion 16 such as an opening or a cut is formed in a region overlapping with the conductive portion 3 and is connected in a cylindrical shape via an attachment portion of the conductive portion 3.
In the eleventh embodiment, the conductive portion 3 is attached to the fabric 20 knitted separately from the body fabric body 2 by bonding or sewing, and is then bonded to the body fabric body 2 through the fabric 20. Alternatively, it is attached by sewing, and this is different from the tenth embodiment in which the conductive portion 3 is knitted into the fabric 15.

FIG. 6D shows a twelfth embodiment of the garment 1 of the present invention. The twelfth embodiment is different from the first embodiment in that a part of the body cloth body 2 in the circumferential direction also serves as the covering portion 4. That is, the covering portion 4 is provided integrally with the body cloth body 2.
Specifically, in the twelfth embodiment, the conductive portion 3 is formed by weaving into a fabric 15 knitted separately from the body fabric body 2, and this fabric 15 is the inner peripheral surface of the body fabric body 2. It is attached to the wearer's skin side by bonding or sewing. The body fabric body 2 has at least a region for overlapping with the fabric 15 (conductive portion 3) so that the stretchability in the circumferential direction is smaller than that of the fabric 15 (so that the tightening force is increased). Knitting is performed after selecting materials, selecting a knitting structure, selecting an elastic yarn to be inserted, and the like.

In the body cloth body 2, it is possible to appropriately select whether the stretchability is reduced only for the region shared with the covering portion 4 or more (including the entire circumference).
Since a space 23 is inevitably generated between the conductive portion 3 and the covering portion 4 (the cloth body 2), this space 23 is an opening of the article accommodating portion 7 described in the fourth embodiment (FIG. 5B). 8 can also be used.

FIG. 6E shows a thirteenth embodiment of the garment 1 of the present invention. The thirteenth embodiment differs from the first embodiment in that a part of the body cloth body 2 in the circumferential direction also serves as the covering portion 4. Although it is substantially the same as the twelfth embodiment, in the thirteenth embodiment, the stuffing 9 is enclosed in the space 23 provided between the conductive portion 3 and the covering portion 4 (the body cloth body 2). This is different from the twelfth embodiment. For the filling 9, see the fifth embodiment (FIG. 5C).

FIG. 6F shows a fourteenth embodiment of the garment 1 of the present invention. The fourteenth embodiment is different from the first embodiment in that a part of the body cloth body 2 in the circumferential direction also serves as the covering portion 4. Although it is substantially the same as the twelfth embodiment, in the fourteenth embodiment, the device device 10 is planned to be accommodated in the space 23 provided between the conductive portion 3 and the covering portion 4 (the body cloth body 2). This is different from the twelfth embodiment. In addition, refer to 6th Embodiment (FIG. 5D) about the point (device arrangement | positioning 3 etc.) which accommodates the device apparatus 10. FIG.

FIG. 7 shows an example in which an anti-slip material 25 is provided toward the wearer on the outer peripheral portion of the conductive surface 3a in the conductive portion 3 (that is, the surface facing the skin surface of the wearer). Providing such an anti-slip material 25 is preferable because it is difficult for the conductive portion 3 to be displaced with respect to the skin surface of the wearer. Such an anti-slip material 25 can be combined with any of the first to fourteenth embodiments described above.

The anti-slip material 25 can be formed by exposing an elastic thread around the conductive surface 3a. You may make it perform a heat setting process as needed in order to improve grip property. Also, instead of elastic yarn, a resin material or ink material that exhibits gripping properties is sprayed, applied, printed, imprinted (a method in which the material passes through the fabric and is scattered on the side opposite to the imprinted surface. ) Or the like.

FIG. 8 shows a fifteenth embodiment of the garment 1 of the present invention. In the fifteenth embodiment, an unconnected portion 16 such as an opening or a cut is formed in a part of the body cloth body 2 in the circumferential direction.

FIG. 9 shows an arrangement example of the pocket-shaped covering portion 4 when the pocket-shaped covering portion 4 is provided on the body cloth main body 2. The pocket-shaped covering portion 4 also serves as the article accommodating portion 7 (not shown). For details such as the arrangement relationship with the conductive portion 3, the fourth embodiment (FIG. 5B) and the sixth embodiment See (Figure 5D).
In FIG. 9, it is assumed that the covering portion 4 is arranged at a total of four locations, two left and right locations corresponding to the chest of the wearer and two left and right locations corresponding to the height of the heart. Needless to say, a conductive portion 3 (not shown) is provided corresponding to each covering portion 4.

FIG. 10 shows an arrangement example of the covering portion 4 when a part of the body cloth body 2 in the circumferential direction also serves as the covering portion 4. In order to share the covering portion 4 with a part of the body fabric main body 2, it is necessary to provide the fabric 15 including the conductive portion 3 on the inner peripheral surface side (side facing the wearer's skin surface) of the body fabric body 2. There is. Refer to the twelfth embodiment (FIG. 6D) and the fourteenth embodiment (FIG. 6F) for details such as the arrangement relationship with the fabric 15 and the conductive portion 3.

FIG. 11 shows an example in which the body cloth body 2 is provided with a ventilation portion 27 that penetrates between the surface facing the skin surface of the wearer and the outer surface by a porous structure or a mesh structure. By providing such a ventilation part 27, in the case of collecting data from the conductive part 3 while exercising or the like while wearing the garment 1, the sweat of the wearer is promoted, So that overload does not act on Therefore, it is useful to obtain accurate data that is not affected by disturbance such as the constitution and physical strength of the wearer or the data collection environment.

Such a ventilation portion 27 can be realized by adopting transfer or lace knitting when the body fabric body 2 is knitted. In some cases, such as separate fabrics knitted by transfer or lace stitching, porous fabrics (including non-woven fabrics) and mesh materials are attached to the body fabric body 2 by bonding or sewing. Also good.
Needless to say, the arrangement and the number of the ventilation portions 27 can be appropriately changed according to the arrangement of the clothing shape and the conductive portion 3.

FIG. 12 shows another example of the body cloth main body 2. In the example shown, it is a half-pants type undergarment. In such a case, the conductive part 3 and the covering part 4 can be arranged corresponding to the thigh, waist, buttocks, etc. of the wearer.
By the way, the “stretchable garment having a conductive part” according to the present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.

For example, the conductive part 3 can use the conductive surface 3a as a heater.
The body cloth main body 2 may have a cylindrical shape, a tapered cylindrical shape, a gourd cylindrical shape, etc. that are passed through the wearer's torso, neck, arms, fingers, legs, and the like. In these cases, it is not always required to be seamless in the circumferential direction, and the body fabric body 2 can be formed in a belt shape and wrapped around the wearer's target site. In order to maintain the winding state, various fastening methods such as a strap fastening, a button fastening, a hook fastening, a hook-and-loop fastener fastening, and a wire fastener fastening can be employed in addition to the belt fastening around the circumferential direction. If necessary, an adjustment function for making the circumference (cylinder diameter) at the time of fastening variable may be provided.

A method of forming the conductive portion 3 by performing printing using a conductive ink may be employed.

Next, an embodiment of “clothes for obtaining biometric data” according to the present invention will be described with reference to the drawings.
13 to 15 show a sixteenth embodiment of a garment for acquiring biometric data 100 according to the present invention (hereinafter referred to as “the garment 100 of the present invention”). The garment 100 of the present invention has a basic configuration in which a conductive portion 103 for ensuring electrical continuity with the skin surface of the wearer is provided on a part of the body fabric body 102. The body cloth main body 102 is made of a non-conductive fiber material in principle (at least the insulating region centered on the arrangement portion of the conductive portion 103). On the other hand, the conductive portion 103 is formed by exposing the conductive yarn on at least a surface directed to the skin surface of the wearer (hereinafter referred to as “conductive surface”).

In the garment 100 of the present invention, the body cloth body 102 is provided with a device mounting portion 104 that allows the detection device 105 to be detachable. When the detection device 105 is mounted on the device mounting portion 104, The detection device 105 and the conductive portion 103 can be electrically connected.
Further, the body cloth main body 102 is provided with a pressing biasing portion 106. The pressing urging unit 106 is arranged so as to overlap the detection device 105 held by the device mounting unit 104 and presses the conductive unit 103 and the detection device 105 in the mutual contact direction.

The detection device 105 is an electronic device for acquiring biological data such as heart rate, body surface temperature, and pulse wave from the wearer. The detection device 105 applied in the sixteenth embodiment is a square type. However, the outer shape and size of the detection device 105, the arrangement and shape of a plurality of detection contacts 110 and 111 (generally two for positive electrodes and one for negative electrodes as shown in FIG. 15), etc. There is no particular limitation.

In many cases, the detection device 105 brings the detection contacts 110 and 111 into direct contact with the skin surface of the wearer or indirectly through a conductive pad with a jelly-like (gel-like) adhesive. The biometric data acquired in (1) is transmitted to an information processing device such as a computer installed in the vicinity by wireless or wired communication to create an electrocardiogram or electromyogram.
In the sixteenth embodiment, the case where the body cloth main body 102 is a T-shirt type upper garment (including training wear and underwear) is shown. That is, the body body 102 forms left and right sleeves with respect to a seamless tubular fabric in the circumferential direction, and opens a collar on one side in the tube axis direction ([Ariaki]: a hole through which the head of the wearer passes. ). And with respect to such an upper-cloth-type body cloth main body 102, the electroconductive part 103 and the apparatus mounting part 104 are set as the arrangement | positioning matched with the wearer's chest.

In the sixteenth embodiment, the spacer member 112 is provided on the inner surface side of the body cloth body 102 (the side facing the skin surface of the wearer), and the device mounting portion 104 is formed on the spacer member 112. The conductive member 103 is arranged on the inner side (the wearer's skin side) so that the spacer member 112 (the device wearing unit 104) is sandwiched between them, and pressed against the outer side (the clothing outer side) of the device wearing unit 104. It is assumed that the urging portion 106 is arranged.

Note that a wiring portion for the conductive portion 103 may be formed in the body cloth main body 102 or the spacer member 112 in some cases.
Hereinafter, the body body 102 will be described in detail first. The body body 102 can be knitted using a non-conductive fiber material as described above. Specific examples of the fiber material include synthetic fiber (for example, polyester fiber and nylon fiber), natural fiber, and a material obtained by mixing synthetic fiber and elastic yarn.

Further, the knitting structure adopted for the body fabric body 102 is not limited at all. For example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, a Milan rib or a cardboard knit) can be employed. Naturally, for knitting, not only a circular knitting machine but also a flat knitting machine can be used. In addition, the organization knitted by the weft knitting as listed above may be a knitting organization (tricot knitting, Raschel knitting, Miranese knitting, etc.) knitting by warp knitting.

When knitting the body body 102, elastic yarns are further mixed so that abundant expansion and contraction can be obtained in the direction of expanding and contracting the cylinder diameter (peripheral length) and the cylinder shaft length. This is suitable for fixing the mounting position and facilitating removal.
Here, the “elastic yarn” maintains a contracted state when no tensile force is applied (non-extension = normal state), and freely expands according to the tensile force when a tensile force is applied, and When the tensile force is released and the load is restored when no load is applied, the material is restored (contracted) from the stretched state to the original contracted state.

As a method for mixing elastic yarns, a form selected from at least one of inlay, drawing, plating, knit, or composite yarn may be adopted. For elastic yarn, polyurethane or rubber-based elastomer material may be used alone, or covering yarn using polyurethane or rubber-based elastomer material for “core” and nylon or polyester for “cover” can do. By employing such a covering yarn, functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring can be imparted to the garment 100 of the present invention. It is also useful for improving the feel (feel) and controlling elongation.

The body fabric body 102 knitted in this manner sufficiently follows the movement of the wearer, and has elasticity to such an extent that it can be stretched and recovered. The stretchability of the body fabric main body 102 is such that it causes vertical stretch along the height direction of the wearer and lateral stretch along the waist direction of the wearer, and the vertical stretch may hinder the movement of the wearer. It has a weak elastic resistance to the extent that the body fabric body 102 is perfectly fitted to the wearer in the horizontal expansion and contraction, and the strong elastic resistance to prevent the slippage has been developed, thereby increasing the pressing force on the skin surface. Those are preferred.

That is, when the wearer wears, the Y direction (height direction) has a small elastic resistance and easily expands and contracts following the movement of the body, while the elastic resistance is large and hardly stretched in the X direction (trunk direction). It is preferable that the cloth body main body 102 be pressed in the Z direction (body) as a result.
In this way, a specific knitting method for knitting a cylindrical fabric that has a strong clamping force because it is relatively easy to stretch in the Y direction and difficult to stretch in the X direction, and presses the body fabric body 102 in the Z direction. For example, a method of performing milling with a covering yarn using polyurethane equivalent to 22 dtex and inlaying about 110 dtex of polyurethane as an insertion yarn can be cited as a method employing a knitting structure of a milling knitting inlay.

Next, the conductive part 103 will be described in detail. In order for the conductive parts 103 to contact the detection contacts 110 and 111 of the detection device 105 separately, the same number ( conductive parts 103a and 103b) as the detection contacts 110 and 111 are provided in a state of being separated and insulated from each other. The size of each conductive portion 103a, 103b (particularly the surface used as a conductive surface) should be larger than the detection contacts 110, 111 of the detection device 105 (contact area when contacting the skin surface of the wearer). Is preferred. Specifically, when the direction surrounding the wearer's torso, neck, legs, arms, or fingers is the horizontal direction (see arrow W in FIG. 15), at least the horizontal direction (W) Is the enlarged size.

By enlarging the conductive portions 103a and 103b in this way, there is an advantage that reliable conduction with the skin surface of the wearer can be obtained, and that the conduction can be reliably maintained even when the wearer moves. The extent of enlargement can be appropriately changed depending on the type of biometric data to be obtained, the arrangement of the conductive surface (contact location with the wearer), and the like.
The planar shape of each of the conductive portions 103a and 103b is a shape that is laid down so that the convex protrusions face each other as shown in FIG. However, it is also possible to use a saddle shape (L-shape) as shown in FIG. 16, and the planar shape of the conductive portions 103a and 103b is the size and shape of the detection device 105, the shape and structure of the detection contacts 110 and 111. These can be changed as appropriate according to the arrangement.

The conductive yarn forming the conductive portions 103a and 103b is formed of a metal strand, a metal-coated wire, carbon fiber, or the like.
Convex shapes and saddle-shaped (L-shaped) may be formed integrally with the same conductive material, or a plurality of conductive materials with different materials may be sewn, bonded, locking tools (snap buttons, etc.) ), Engaging structures (such as hook-and-loop fasteners), etc., may be combined to form a composite structure.

As specific examples of the metal component in the metal strand or the metal-coated wire, gold, platinum, silver, copper, nickel, chromium, iron, copper, zinc, aluminum, tungsten, stainless steel and the like are suitable. In addition, pure metals such as titanium, magnesium, tin, vanadium, cobalt, molybdenum, tantalum, and alloys thereof (brass, nichrome, etc.) can be used.
As the metal strand, not only a continuous long wire but also a twisted single wire can be used. On the other hand, when the core material is a resin fiber, wire or animal or plant fiber in a metal-coated wire, a wet coating method or a powder adhesion method can be used, including plating treatment employed in resin plating methods, etc. Good. Further, when the core material is a metal wire, a thermal spraying method, a sputtering method, a CVD method, or the like can be employed. Monofilaments, multifilaments, and spun (spun) yarns may be used as the core material, or wooly processed yarns, covering yarns such as SCY and DCY, and bulky processed yarns such as fluffed yarns may be used.

In addition, these metal wires, metal-coated wires, and carbon fibers may be mixed with non-conductive fibers. For example, a spun (spun) yarn can be used for blended yarn, covering yarn, or assortment. It is also possible to mix with a fiber having a melting point and a softening point higher than the heat setting temperature.
As the knitting structure used for the conductive surface, for example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, Milan rib, corrugated cardboard knit, Kanoko, pile, etc.) can be adopted.

Depending on the case, it is also possible to adopt a structure in which the base yarn portion serving as the basis of the conductive portions 103a and 103b is knitted as a full knit of the various knitting structures and knitted by float knitting on the conductive surface side of the same region. . In this case, the float yarn of the float knitting rises beyond the height in the thickness direction due to the knitting structure of the ground yarn. Therefore, the contact of the conductive surface is further ensured with respect to a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. In addition, it will follow even more precise movements of the skin surface. Therefore, reliable conductivity can be obtained.

When the entire conductive parts 103a and 103b (the entire fabric thickness) are knitted with the above-described various knitting structures using the above-described conductive yarn, not only the conductive surface but also the surface opposite to the conductive surface. This also has a conductive structure, and conduction between the front and back surfaces is also obtained. In such a case, the surface opposite to the conductive surface can be used as an electrode surface for electrically connecting to the detection contacts 110 and 111 of the detection device 105.

As shown in FIG. 14, in the sixteenth embodiment, the detection contact 110 of the detection device 105 is exactly the one surface of the conductive portions 103a and 103b as the conductive surface and the other surface opposite to the conductive surface as the electrode surface. , 111 is a use example.
Next, the device mounting unit 104 will be described in detail. The device mounting unit 104 is a place for holding the detection device 105 with respect to the body cloth main body 102. In a state where the device mounting unit 104 holds the detection device 105, the detection device 105 is in a state in which the relative positional relationship with the body cloth body 102 is not shifted even when the wearer operates. Is preferred. Therefore, in the sixteenth embodiment, the spacer member 112 is provided on the inner surface side of the body cloth main body 102 as described above, and the device mounting portion 104 is provided for the spacer member 112.

Specifically, the spacer member 112 is formed in a plate shape having a thickness equal to or less than the thickness of the detection device 105, and the detection device 105 is fitted by opening or denting the plate surface. It has a structure. In other words, the outer peripheral side surface of the detection device 105 comes into contact with the opening (or in the recess) provided in the spacer member 112, the detection device 105 is held, and the movement of the detection device 105 with respect to the body cloth body 102 is substantially omitted. In this case, the device mounting portion 104 is formed at a portion that contacts the detection device 105.

As the forming material of the spacer member 112, various materials such as towels and the like, cotton, three-dimensional knitted fabric, shredder waste, foamed polystyrene, sponge, rubber, silicon, urethane, air bags, gel encapsulated bags can be adopted. .
The device mounting portion 104 provided on the spacer member 112 may be any device as long as it is in contact with at least two locations facing each other (for example, a pair of diagonal positions of the detection device 105) on the side surface of the detection device 105, and is not necessarily detected. It is not necessary to contact the entire circumference of the device 105. In some cases, a small spacer member 112 that is separated from each other is disposed so as to abut only on two opposite side surfaces or diagonal portions of the detection device 105, and the device mounting portion 104 is disposed between the two spacer members 112. May be formed.

In the sixteenth embodiment, the spacer member 112 is provided so as to correspond to only about half a circumference of the body cloth main body 102. However, the range may be less than a half circumference, or may be provided around the entire inner surface of the body cloth body 102. Also good.
Examples of the joining method when attaching the spacer member 112 to the body cloth body 102 or attaching the conductive portion 103 to the spacer member 112 include adhesion by an adhesive, thermal fusion by a thermoplastic resin, Appropriate methods such as sewing with a sewing machine or hooking with a hook-and-loop fastener can be adopted.

Next, the pressing urging unit 106 will be described in detail. The pressing and biasing unit 106 has a biasing force that enables the conductive units 103a and 103b and the detection device 105 to be pressed even at the maximum extension caused by the movement of the wearer within the schedule.
The pressing biasing unit 106, for example, by performing knitting by performing elastic yarn insertion, yarn switching, knitting structure change, loop length change, or a combination of these operations during knitting of the body fabric body 102, It can be formed integrally with the body cloth body 102.

Specifically, the fiber material and the knitting structure forming the pressing and urging portion 106 are basically the same as those employed for the body fabric main body 102 except for the strength of the urging force. Similarly to the case of the body fabric body 102, the pressing and biasing unit 106 also causes vertical expansion / contraction along the wearer's height direction and lateral expansion / contraction along the wearer's waistline direction. The same applies to the point that the horizontal expansion and contraction is strengthened so that the wearer's waistline can be firmly fitted.

In the sixteenth embodiment, the pressing biasing portion 106 is illustrated as being formed in a cylindrical shape as in the case of the body cloth main body 102, but the pressing biasing portion 106 corresponds to the detection device 105. You may provide so that only a part may exist.
In some cases, the pressing and urging portion 106 can also be formed by joining a fabric with strong biasing force knitted separately from the body fabric body 102 to the body fabric body 102 by sewing or the like.

As apparent from the above description, in the garment 100 of the present invention, when the detection device 105 is mounted on the device mounting portion 104 and the wearer wears the garment 100 of the present invention, the pressing biasing portion 106 is The detection device 105 is pressed against the conductive portions 103a and 103b by a strong biasing force, and the conductive portions 103a and 103b are pressed against the skin surface of the wearer. As a result, the detection contacts 110 and 111 of the detection device 105 and the conductive portions 103a and 103b are in surface contact with each other to be in a conductive state, and the conductive portions 103a and 103b and the skin surface of the wearer are in surface contact with each other. It becomes a conductive state. These continuity states are maintained even when the wearer moves, so that the detection device 105 can reliably acquire biological data.

As described above, the garment 100 of the present invention can be implemented as a general-purpose garment (other than a medical one having a strong biasing force enough to intentionally press the skin surface). Of course, it is needless to say that medical implementation is possible.
By the way, as shown in FIG. 17, the body cloth main body 102 is provided with a loading / unloading port 116 in an arrangement matching the device mounting portion 104 from the opposite side (outside of the clothing) to the side facing the skin surface of the wearer. be able to. The entrance / exit 116 is for making the detection device 105 detachable from the device mounting portion 104. In the illustrated example, an opening / closing tool 120 such as a line fastener (generally called “zipper” or “chuck”) that can be opened and closed in the height direction of the wearer is attached to the loading / unloading opening 116.

If the entrance / exit 116 is provided in the body cloth body 102 in this way, the detection device 105 can be attached to and detached from the device mounting portion 104 while wearing the clothing 100 of the present invention, which is extremely convenient. Further, by providing the opening / closing tool 120 at the entrance / exit 116, it is possible to obtain a holding and stabilizing action, a drop-off preventing action, a visual blocking action (improving appearance), and the like of the detection device 105 attached to the device attachment portion 104, which is extremely useful. It becomes.

Note that when the opening / closing tool 120 is opened / closed, the opening / closing tool is prevented in order to prevent the detection device 105 from being caught and becoming difficult to operate or the detection device 105 being damaged. It is preferable to attach the backing fabric 121 in an arrangement that partitions the space 120 between the device mounting portion 104 and the device mounting portion 104.
Further, when a non-conductive lining 122 is attached to the inside of the conductive portions 103a and 103b that matches the device mounting portion 104, both the conductive portions 103a and 103b are connected, and the detection contact of the detection device 105 is detected. There is an advantage that it is possible to prevent creases or misalignment at the contact portions with 110 and 111.

18 to 21 show a seventeenth embodiment of the garment 100 of the present invention. The seventeenth embodiment is a case where the detection device 105 is applied to an elliptical type instead of the square type described in the sixteenth embodiment, and the detailed configuration differs due to this.
In the detection device 105 applied in the seventeenth embodiment, the detection contacts 110 and 111 are distributed and arranged near both ends in the longitudinal direction of the elliptical shape. Therefore, as shown in FIGS. 20A, 20B, 20C, 20D, and 21, the conductive portions 103a and 103b are also arranged so as to be distributed near both ends of the detection device 105 in the longitudinal direction.

Each of the conductive portions 103a and 103b has a dome shape that covers the detection device 105 across its short side. In addition, a bag-shaped dead end structure is provided at a position covering the longitudinal end portion of the detection device 105 so that the detection device 105 can be contained to prevent the movement and escape of the detection device 105 in the longitudinal direction.
Further, in the seventeenth embodiment, as shown in FIG. 19, the conductive portions 103 a and 103 b are disposed inside the device mounting portion 104 with the device mounting portion 104 interposed therebetween, and the body cloth body 102 is disposed outside the device mounting portion 104. As arranged. Each of the conductive parts 103a and 103b has a biasing force that enables pressing against the detection device 105 even at the maximum extension caused by the movement of the wearer within the schedule, and by having this biasing force, Each of the conductive portions 103a and 103b also serves as the pressing and biasing portion 106.

Here, “scheduled movement of the wearer” means a movement that is necessary for the acquisition of biometric data but excludes other extreme movements and special movements that are not performed in daily life. Shall.
Accordingly, in the seventeenth embodiment, the pressing and biasing unit 106 ( conductive portions 103a and 103b) presses itself (the conductive portions 103a and 103b) against the detection device 105 by a strong biasing force. In addition, the conductive portions 103a and 103b are pressed against the skin surface of the wearer due to the elasticity of the body cloth body 102 with the tightening force. As a result, the detection contacts 110 and 111 of the detection device 105 and the conductive portions 103a and 103b are in surface contact with each other to be in a conductive state, and the conductive portions 103a and 103b and the skin surface of the wearer are in surface contact with each other. It becomes a conductive state.

Even if such a configuration is adopted, the cylindrical pressing and biasing unit 106 integrated with the body body 102 as described in the sixteenth embodiment can be used in the seventeenth embodiment as well. It is.
As a specific method for imparting an urging force to each of the conductive parts 103a and 103b, conductive yarns are aligned in the region where the conductive parts 103a and 103b are formed on the basis of a stretchable fabric, and plating and inlay are performed. A method may be employed in which the yarns are mixed with the same yarn or the like, or conductive yarns (including covering yarns and twisted yarns having conductivity) are knitted by yarn feeding switching.

In the seventeenth embodiment, since the conductive portions 103a and 103b are arranged apart from each other in accordance with the elliptical shape of the detection device 105, an opening is formed between the two conductive portions 103a and 103b. It is configured to be used as the entrance / exit 125 of the detection device 105. The entrance / exit 125 is accompanied by a contracting force in the direction of reducing the opening due to the conductive portions 103a and 103b and the base fabric having stretchability and tightening force. Therefore, when the detection device 105 as shown in FIGS. 20A, 20B, 20C, and 20D is inserted and removed, the opening edge of the insertion / exit port 125 surrounds (tightens) the detection device 105 and exhibits a locking force. This has the advantage that it becomes a non-slip effect (a drop-off prevention effect) and there is no failure in taking in and out the detection device 105. In addition, as shown in FIG. 20D, when the insertion is completed, the outlet / entry port 125 automatically reduces in diameter, which leads to an action of increasing the holding force of the detection device 105.

In this type of elliptical type detection device 105, a sensor unit 127 for detecting body surface temperature, pulse wave, and the like is provided at an intermediate position in the longitudinal direction (between the detection contacts 110 and 111). There may be. The entrance / exit 125 can be used effectively for exposing the sensor unit 127 and bringing it into contact with the skin surface of the wearer.
Other configurations and operational effects are substantially the same as those in the sixteenth embodiment, and a detailed description thereof is omitted here.

In the conductive portions 103a and 103b, the position covering the longitudinal end of the detection device 105 is not limited to the bag-shaped dead end structure. For example, as shown in FIG. 22, it is possible to prevent the detection device 105 from moving in the longitudinal direction and to escape even by providing a narrowing guide portion 130 by sewing or bonding to form an opening 131 narrower than the detection device 105. Can get.

Further, the elliptical type detection device 105 is not limited to adopting a configuration that also serves as the pressing and urging unit 106 against the conductive units 103a and 103b. For example, as shown in FIGS. 23 and 24, it is possible to employ conductive portions 103a and 103b that are substantially the same as those described in the sixteenth embodiment.
FIG. 25 shows an eighteenth embodiment of the garment 100 of the present invention. In the eighteenth embodiment, the pressing urging unit 106 is arranged in a hooked manner with respect to the body cloth main body 102 so that the range of action of the urging force can be distributed to the whole body cloth main body 102 in a well-balanced manner. . Other configurations and operational effects are substantially the same as those in the sixteenth embodiment, and a detailed description thereof is omitted here.

FIG. 26 shows a nineteenth embodiment of the garment 100 of the present invention. In the nineteenth embodiment, the portion where the conductive portions 103a and 103b are disposed with respect to the body cloth body 102 is separated from the portion where the device mounting portion 104 of the detection device 105 is disposed, and a conductive line is formed between these portions. 135 is wired. As described above, in the conductive portions 103a and 103b, the use of the surface opposite to the conductive surface as the electrode surface is not limited.

Other configurations and operational effects are substantially the same as those in the sixteenth embodiment, and a detailed description thereof is omitted here.
FIG. 27 shows a twentieth embodiment of the garment 100 of the present invention. The twentieth embodiment shows an example in which a ventilating portion 137 is provided in the body fabric main body 102 so as to penetrate between the surface facing the skin surface of the wearer and the outer surface by a porous structure or a mesh structure. Providing such a ventilation part 137 facilitates sweating of the wearer when collecting data from the conductive part 103 while exercising or the like while wearing the garment 100 of the present invention. It is possible to prevent overload from acting on. Therefore, it is useful to obtain accurate data that is not affected by disturbance such as the constitution and physical strength of the wearer or the data collection environment.

Such a ventilation portion 137 can be realized by adopting transfer or lace knitting when the body fabric body 102 is knitted. In some cases, other fabrics knitted by transfer or lace stitching, and porous fabrics (including non-woven fabrics) or mesh materials may be attached to the body fabric body 102 by bonding or sewing. Also good.
It goes without saying that the arrangement and the number of the ventilation portions 137 can be changed as appropriate according to the arrangement of the clothing shape and the conductive portion 103.

FIG. 28 shows a twenty-first embodiment of the garment 100 of the present invention. The twenty-first embodiment shows another example of the body cloth main body 102. In the example shown, it is a half-pants type undergarment. In such a case, the conductive portion 103 and the pressing biasing portion 106 can be arranged in correspondence with the thigh, waist, buttocks, etc. of the wearer.
FIG. 29 is an embodiment obtained by further developing the nineteenth embodiment (FIG. 26). Basically, the present embodiment is the same as the nineteenth embodiment in that the conductive portions 103a and 103b and the device mounting portion 104 of the detection device 105 are separated from each other and are wired by a conductive line 135. The embodiment is characterized in that the conductive line 135 is detachable between the conductive portion 103 a and the device mounting portion 104 and between the conductive portion 103 b and the device mounting portion 104.

By adopting such a configuration, the conductive portions 103a and 103b can be freely exchanged for a plurality of types having different shapes and areas, and the conductive portions 103a and 103b and devices for the body cloth body 102 (not shown). An advantage that the arrangement of the mounting portion 104 can be freely set is obtained. In particular, it is useful when the conductive portions 103a and 103b are desired to increase the contact area with the skin surface of the wearer.

It is preferable to use a conductive line 135 having longitudinal stretchability and bending flexibility. Thus, the conductive portions 103a and 103b can be freely moved within a predetermined range between the conductive portion 103a and the device mounting portion 104 and between the conductive portion 103b and the device mounting portion 104. In addition, the apparatus mounting unit 104 can follow up independently of the movement of the wearer, so that it is possible to obtain stable data acquisition.

There are button-type metal hooks for the joints 142a and 142b used for connecting the device mounting part 104 and the conductive line 135 and the joints 143a and 143b used for connecting the conductive line 135 and the conductive parts 103a and 103b. It is recommended to use a combination. In addition, about a hook engaging tool, if the male-female type is reversed at both ends of the conductive line 135, the device mounting portion 104 and the conductive portions 103a and 103b are directly coupled without using the conductive line 135. Options can also be provided, which is convenient.

Needless to say, the pressing and biasing portion 106 is made conductive, and the pressing and biasing portion 106 and the joint portions 142a and 142b are electrically connected. Therefore, by making the pressing biasing portion 106 contact the skin surface of the wearer, the pressing biasing portion 106 can also act as a conductive portion (the conductive portion 103a connected via the conductive line 135). , 103b will cause the enlargement of the conductive surface).

A combination of the device mounting portion 104 and the conductive portions 103a and 103b is prepared as a separate body from the body fabric main body 102, and the body fabric main body 102 has a region in which all or part of the body fabric has strong tension. The combination of the device mounting portion 104 and the conductive portions 103a and 103b is provided at a required location (location where biometric data is to be obtained) each time in the strong tension region. It is good also as a structure which enables attachment with sewing, adhesion | attachment, a hook-and-loop fastener, etc.

By the way, in the present invention, the contact between the conductive portions 103a and 103b and the detection contacts 110 and 111 of the detection device 105 is forcibly pressed by the urging force of the pressing urging portion 106. Reliable conductivity can be obtained.
However, although illustration is omitted, it is even more reliable by adopting a structure in which the conductive portions 103a, 103b and the detection contacts 110, 111 of the detection device 105 are mechanically engaged by the female hook and the male hook. Conductivity can be obtained.

Even when surface contact is adopted, anti-slip treatment is applied to the conductive surfaces (skin surface side of the wearer) and electrode surfaces (detection contact points 110 and 111 side of the detection device 105) of the conductive parts 103a and 103b. This prevents the displacement of the conductive portions 103a and 103b due to slippage, and as a result, increases the conductivity.
In this anti-slip treatment, at least one of a heat fusion material or a heat fusion material is mixed with the conductive yarn used to form the conductive portions 103a and 103b, and then the conductive portion 103 is knitted and heat set after knitting. This is a process in which a portion where the conductive yarn intersects in the knitted structure is fused or bonded with a resin. Therefore, heat fusion materials and heat fusion materials are excellent in elasticity (elasticity), heat fusion by heating, and high degree of elasticity without loss of elasticity (elasticity) at the heat fusion site. It is good to use what possesses property (elasticity).

The difference between thermal fusion and thermal fusion is in the strength of the bonding force generated by cooling from the semi-molten state (the strong bonding force is thermal fusion, and the weaker is the thermal fusion. is there).
Specifically, a low melting point polyurethane can be given as a representative example of the heat-sealing material or the heat-sealing material. Low melting point polyurethane is an optimal example. In addition, condensation polymers such as polyethylene, nylon (6 and 66), polypropylene, polyvinyl chloride, vinyl polymers, polyamides, and the like can be used.

In the method of mixing the heat-bonding material or the heat-bonding material with the conductive yarn, the conductive yarn is used as a “core (or cover)”, and the yarn made of the heat-bonding material or the heat-bonding material is used as “ A method using a covering yarn (which may be SCY or DCY) used as a “cover (or core)”, or a conductive yarn or a yarn made of a heat-fusion material or a yarn made of a heat-sealing material are arranged together (not as a plating knitting) There is a method).

The conductive yarn after heat setting is required to have a conductive component exposed on a part or all of the yarn surface. Therefore, the exposed portion of the conductive yarn is generated by appropriately adjusting the thickness and amount (number) of yarns made of heat-fusion material or yarns made of heat-fusion material, and the heating temperature when performing heat setting. Like that.
By the way, the “clothing for biometric data acquisition” according to the present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.

For example, the body cloth main body 102 may have a cylindrical shape, a tapered cylindrical shape, a gourd cylindrical shape, or the like. In these cases, it is not always required to be seamless in the circumferential direction, and it is also possible to form the body cloth body 102 in a band shape and wrap it around the target site of the wearer. In order to maintain the winding state, it is possible to employ various fastening methods such as strap fastening, button fastening, hook fastening, hook-and-loop fastening, etc. in addition to belt fastening around the circumferential direction. If necessary, an adjustment function for making the circumference (cylinder diameter) at the time of fastening variable may be provided.

The conductive portions 103a and 103b can be formed by a method of sewing (embroidery) a conductive thread on a base fabric or printing using a conductive ink or conductive silicon.
As shown in FIG. 17, in the body cloth main body 102, when the entrance / exit 116 is provided on the opposite side (outside the clothing) from the side facing the skin surface of the wearer, the opening / closing tool 120 is provided at the entrance / exit 116. Is not limited. In the case where the opening / closing tool 120 is provided, as the opening / closing tool 120, it is possible to adopt a belt stopper, a string stopper, a button stopper, a hook stopper, a hook-and-loop fastener stopper, etc., in addition to the wire fastener. .

The outer shape and size of the detection device 105, the number and arrangement of the detection contacts 111, the shape, the connection structure with the counterpart contact, etc. are not limited at all. Therefore, in the garment 100 of the present invention, it goes without saying that the number and arrangement of the conductive portions 103, the shape, the connection structure with the counterpart contact, and the like can be appropriately changed in accordance with the detection device 105 to be attached. The same applies to the device mounting portion 104 and the pressing biasing portion 106 as the conductive portion 103.

Next, an embodiment of “clothing having a water-permeable conductive portion” according to the present invention will be described with reference to the drawings.
30 to 32 show a twentieth embodiment of a garment 200 (hereinafter referred to as “the garment 200 of the present invention”) provided with a water-permeable conductive portion according to the present invention. As apparent from FIG. 30, the garment 200 of the present invention is provided with a conductive portion 203 for ensuring electrical continuity with the skin surface of the wearer M on a part or all of the body fabric body 202. Is the basic configuration.

In the garment 200 of the present invention, a “water supply material” that continuously supplies water to the conductive portion 203, or a “coolant” that supplies water to the conductive portion 203 when condensation occurs (hereinafter, these “water supply materials”). ”And“ cooling material ”together and referred to as“ water supply material 206 ”) as shown in FIGS. 31 and 32, the back of the conductive portion 203 (on the back side of the conductive portion 203 as viewed from the wearer M). However, when viewed from the line of sight of the wearer M from another person, it is the front side of the conductive portion 203: in short, it is arranged so as to overlap the lower side of FIG.

The water supply material 206 is limited to supplying water between the skin surface of the wearer M and the conductive portion 203 to form a water film (a water film that does not fail over the entire surface direction of the conductive portion 203). Not), and the conductivity is increased (the electric resistance is reduced). However, there is a slight difference in the water film generation process between the “water supply material” and the “cooling material” as follows.
On the other hand, the “water supply material” has a characteristic of maintaining a wet state for a predetermined time when moisture is sucked at the start of use, and releasing moisture little by little by applying an external force to the outer peripheral surface thereof. . That is, the moisture released from the water supply material penetrates into the conductive portion 203 and oozes out between the skin surface of the wearer M and the conductive portion 203 through the conductive portion 203 to generate the water film. To come.

On the other hand, the “coolant” has a characteristic of maintaining a low temperature state for a predetermined time by a chemical reaction, a freezing process, or use of a liquefied gas. Needless to say, the low temperature state does not mean below zero degrees, and the temperature may be lower than the use temperature (environment temperature) of the coolant. Unlike the water supply material, this coolant may not require water absorption at the start of use.

That is, when this coolant is kept at a low temperature, condensation occurs on the outer peripheral surface, and this condensed water penetrates into the conductive portion 203 (the subsequent action is the same as that of the water supply material). In some cases, the coolant removes heat from the conductive portion 203, so that condensation also occurs in the conductive portion 203 itself, and this condensed water may directly promote the formation of the water film.
In the garment 200 of the present invention, such a water supply material 206 is arranged behind the conductive portion 203, so that the water supply material 206 is brought into contact with and held behind the conductive portion 203. A space is needed to keep it. This space may be simply provided with a mounting window (an opening that exposes the back surface of the conductive portion 203 to the outside of the cloth main body 202) in an arrangement matching the conductive portion 203 with respect to the body cloth main body 202. However, such an installation window requires a separate device for preventing the water supply material 206 from dropping off.

Therefore, preferably, a space-like accommodation portion 215 is provided between the body cloth main body 202 and the conductive portion 203, and the water supply material 206 is detachably accommodated in the accommodation portion 215. .
In the twenty-second embodiment, the housing part 215 is formed by sewing or bonding three sides of the conductive part 203 formed in a rectangular shape to the body cloth body 202 in a U-shape so that the outer periphery 3 of the water supply material 206 or the like. It is assumed that it is formed in a pocket shape surrounding the direction. As a result, the outer periphery of the water supply material 206 is firmly held in addition to the front and back surfaces, and there is no occurrence of misalignment or jumping out in the housing portion 215.

In the garment 200 of the present invention, since water is supplied from the water supply material etc. 206 disposed behind the conductive portion 203 to the skin surface of the wearer M and the conductive portion 203, In this case, it is recommended to provide a pressing and biasing portion 207 that presses the conductive portion 203 toward the skin surface of the wearer M with the water supply material 206 or the like.
This is because when the pressing urging unit 207 is not provided, the moisture contained in the water supply material 206 is difficult to be pushed forward (it is not released in the first place or dissipates in the surface direction), and therefore the conductive portion 203 There is a problem that it is difficult to penetrate. Even if moisture can be skillfully supplied between the skin surface of the wearer M and the conductive portion 203, a water film can be constantly maintained between the skin surface of the wearer M and the conductive portion 203. There is also a concern that it is difficult (the water supply speed to the conductive portion 203 cannot catch up with the drying speed or dissipation speed of the water film).

However, by providing the pressing and biasing portion 207, an appropriate back pressure can always be applied to the water supply material 206, so that a water film is constantly formed between the skin surface of the wearer M and the conductive portion 203. It can be maintained.
By the way, in this 22nd Embodiment, the case where the body cloth main body 202 is made into the T-shirt type upper garment (including training wear and underwear) is shown. That is, the body fabric body 202 forms left and right sleeves with respect to a seamless cylindrical fabric in the circumferential direction, and opens a collar on one side in the cylinder axis direction ([Ariaki]: a hole through which the head of the wearer passes. ). The conductive portion 203 and the pressing urging portion 207 are arranged so as to correspond to the chest of the wearer M or the vicinity thereof, for example, with respect to the upper-cloth-type body cloth body 202.

In the twenty-second embodiment, the pressing and biasing portion 207 has the same cylindrical shape as the circumferential direction of the body cloth main body 202, and is arranged so as to cover the entire back of the water supply material 206 and the like.
In addition, in the twenty-second embodiment, an electronic device for acquiring biological data such as heart rate, body surface temperature, pulse wave, and myoelectricity from a wearer, a therapeutic device used for electromagnetic therapy, and the like (hereinafter, these electronic devices and It is assumed that a device mounting portion 218 is provided so that 17 can be mounted on the body body 202 in a detachable manner.

When the electronic devices 217 are mounted on the device mounting portion 218, the electronic devices 217 and the conductive portion 203 are formed as conductive lines (separate lead wires or formed on the body cloth body 202 with conductive fibers. It can be electrically connected by a line 19 or a fabric surface having a certain spread). The outer shape and size of the electronic devices 217, the arrangement and shape of a plurality of contacts (generally, two for positive electrodes and one for negative electrodes), and the like are not particularly limited.

As is clear from the above description, in the 22nd embodiment, as shown in FIG. 32, the conductive portion 203, the water supply material 206, and the pressing biasing portion 207 are stacked in three layers from the skin surface of the wearer M. It has a structured. Therefore, when the garment 200 of the present invention is worn, the tightening force generated in response to the extension of the pressing biasing portion 207 acts in the direction of pressing the skin surface of the wearer M, and the pressing biasing force is generated by this tightening force. The part 207 presses the water supply material 206 to the conductive part 203 and also presses the conductive part 203 against the skin surface of the wearer M.

Therefore, moisture is appropriately pushed out from the water supply material 206 toward the conductive portion 203, so that the moisture is surely permeated into the conductive portion 203, and as a result, the moisture passes through the conductive portion 203. It oozes out between the skin surface and the conductive portion 203 to cause a water film. Here, the “water film” includes not only liquid but also water vapor (water existing as mist) gathered and spread in a film shape.

Further, the pressing action (tightening force) by the pressing urging portion 207 further increases the conductivity as an effect of the action of reliably bringing the conductive portion 203 into contact with the skin surface of the wearer M. In addition, when the wearer M moves, the conductive portion 203 is prevented from being easily displaced with respect to the skin surface.
FIG. 41A is a waveform diagram (electrocardiogram waveform diagram) showing the conductivity (detection accuracy) when the water supply material 206 is employed when collecting biological data, and FIG. 41B shows the water supply material 206 not being used. It is a wave form diagram which showed the electroconductivity at the time of employ | adopting.

As is clear from FIG. 41A, when the water supply material 206 is adopted, the electrocardiogram waveform can be read cleanly, which can be effectively used for the discovery of various diseases. On the other hand, as apparent from FIG. 41B, when the water supply material 206 is not adopted, the heart rate interval can be roughly read, but a lot of random disturbances are mixed between the peaks of the waveform. It must be said that the overall credibility is not high. Therefore, it is very difficult to determine the causes of various diseases from this waveform alone.

In addition, as shown in FIG. 33 in the twenty-third embodiment of the garment 200 of the present invention, the water stop portion 220 covers the back of the water supply material 206 or the like (surface opposite to the surface facing the conductive portion 203). It is also possible to provide. Needless to say, a sheet or film formed of a water-impermeable material, a coating film, a coating film, or the like may be employed as the water stop portion 220. Depending on the case, it is good also as a similar thing which performed the water-repellent process.

By providing such a water stop part 220, it is possible to prevent the pressing and biasing part 207 and the cloth body main body 202 from getting wet with water by water from the water supply material 206. In other words, since water from the water supply material 206 or the like does not escape unnecessarily, a water film generated between the skin surface of the wearer M and the conductive portion 203 can be maintained for a long time (water drainage can be prevented).
Therefore, when biometric data is collected, highly accurate measurement results can be obtained over a long period of time, and during electrotherapy, the occurrence of electrical stimulation (stinging) can be suppressed over a long period of time. become.

In addition, when the “cooling material” is used as the water supply material 206 or the like, such a water stop unit 220 functions as a heat insulating material or a heat insulating material, which can be said to be more useful.
Further, as shown in FIG. 34 in the twenty-fourth embodiment of the garment 200 of the present invention, the water supply material 206 and the pressing urging unit 207 are integrated so that these two functions can be obtained in one layer. It is also possible to do.

As shown in FIG. 35 in the twenty-fifth embodiment of the garment 200 of the present invention, the water supply material 206, the pressing urging portion 207, and the water stopping portion 220 are integrated so that these three functions can be obtained further. A simple structure is also possible.
As shown in FIG. 36 in the twenty-sixth embodiment of the garment 200 of the present invention, the layer in which the conductive portion 203 and the water supply material 206 are integrated, and the pressing and biasing portion 207 and the water stop portion 220 are integrated. It is also possible to superimpose the layers so that each function can be obtained skillfully.

As shown in FIG. 37 in the twenty-seventh embodiment of the garment 200 of the present invention, from the skin surface of the wearer M, there are a conductive portion 203, a moisture adjusting portion 221, a water supply material 206, a water stopping portion 220, and a pressing biasing portion 207. A stacked structure is also possible.
In this case, the moisture adjusting unit 221 basically functions to hold or slowly release moisture in the same manner as the water supply material 206. However, the water supply material 206 has a moisture release rate. Are different. Therefore, the amount of moisture per unit time penetrating from the water supply material 206 into the conductive portion 203 can be adjusted as appropriate.

38 shows a twenty-eighth embodiment of the garment 200 of the present invention. The garment 200 of the present twenty-eighth embodiment is provided with a waterproof part 222 in an arrangement so as to cover the back of the accommodating part 215 for the water supply material 206 with respect to the body cloth body 202 (pressing biasing part 207). Is. Also for the waterproof part 222, a sheet, a film, a porous body, or the like formed of a non-permeable material, or a coating film or a coating film may be employed. Depending on the case, it is good also as a similar thing which performed the water-repellent process.

By providing such a waterproof part 222, it is possible to prevent the body cloth body 202 (the pressing urging part 207) from getting wet with water from the water supply material 206 or the like. Needless to say, if the waterproof portion 222 and the water stop portion 220 described in the twenty-third embodiment (see FIG. 33) are used in combination, a thorough water-wetting prevention measure for the body fabric body 202 can be achieved.
FIG. 39 shows a twenty-ninth embodiment of a garment 200 of the present invention. In the garment 200 of the 29th embodiment, the pressing and biasing portion 207 is not arranged to cover the back of the water supply material 206 and the like, and the right and left sides of the water supply material 206 are pulled in opposite directions by the pressing biasing portion 207. In such a state, it is arranged to be wound around the wearer M. That is, the conductive portion 203 is directly attached to the body cloth body 202.

FIG. 40 shows a thirtieth embodiment of the garment 200 of the present invention. The garment 200 of the thirtieth embodiment includes a water supply material or the like from the back (the side opposite to the side facing the wearer's skin and the outside of the garment) in the housing portion 215 for the water supply material 206. A loading / unloading port 225 that allows the 206 to be attached and detached is provided. An opening / closing tool 226 such as a line fastener (generally called “zipper”, “chuck” or the like) that can be opened and closed in the height direction of the wearer is attached to the entrance / exit 225.

If the entrance / exit 225 is provided in the body cloth body 202 in this way, the water supply material 206 and the like can be taken in and out of the storage portion 215 while wearing the clothing 200 of the present invention, which is extremely convenient. Further, by providing the opening / closing tool 226 at the entrance / exit 225, it is possible to obtain a holding and stabilizing action of the water supply material 206, a drop-off preventing action, a visual blocking action (improving appearance), and the like, which is extremely useful.

In addition, when opening / closing the opening / closing tool 226, in order to prevent the water supply material etc. 206 from being caught and becoming difficult to operate the opening / closing tool 226 or being damaged, It is preferable to attach the backing fabric 227 so as to partition the opening / closing tool 226 and the water supply material 206. The opening / closing tool 226 can be replaced with a hook, a button, a hook-and-loop fastener, a belt stopper or a string stopper wound in the circumferential direction, and the backing fabric 227 can be omitted by performing these replacements. It is.

Next, each of the water supply material 206, the body cloth body 202, the conductive portion 203, and the pressing biasing portion 207 will be described in further detail.
First, the water supply material 206 will be described in detail. As described above, the water supply material 206 includes “water supply material” and “cooling material”.
Of these, specific examples of “water supply materials” include polyvinyl alcohol (PVA) sheets, absorbent polymers (highly water-absorbing polymers), cotton, rayon, and cupra (shiny yarn made using copper ammonia (rayon). ), Nylon and the like. In addition, sponges, fabrics, non-woven fabrics, cardboard, paper, porous materials, and the like may be used.

The absorbent polymer is a group of resins obtained by polymerizing water-soluble monomers such as polyvinyl alcohol and polyethylene glycol, for example, an acrylonitrile polymer compound, sodium polyacrylate, and a copolymer (also referred to as an acrylic acid polymer in Japan Catalyst). Also known as product names such as Aquaric L series and H series), Sumitomo Seika's product name: Aqua Keep.

On the other hand, specific examples of “cooling material” include, for example, a type that uses evaporation (heat of vaporization), a type that uses ice as a polymer absorbent, a type that causes ammonium nitrate or urea to melt with water, and menthol. The type to do. Of course, it is also possible to freeze and use water or fabrics containing water.
Next, the body cloth body 202 will be described in detail. In principle, the body fabric body 202 is formed as a fiber structure of a non-conductive fiber material (excluding at least the portion where the conductive portion 203 is disposed). As the fiber structure, a knitted structure or a woven structure can be adopted. Specific examples of the fiber material include synthetic fiber (for example, polyester fiber and nylon fiber), natural fiber, and a material obtained by mixing synthetic fiber and elastic yarn.

Further, the knitting structure adopted for the body fabric body 202 is not limited at all. For example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a change organization thereof (for example, Milano rib, corrugated cardboard knit, Kanoko, etc.) can be employed. Naturally, for knitting, not only a circular knitting machine but also a flat knitting machine can be used. In addition, the organization knitted by the weft knitting as listed above may be a knitting organization (tricot knitting, Raschel knitting, Miranese knitting, etc.) knitting by warp knitting.

When knitting the main body 202, the elastic yarn is further mixed so that abundant expansion and contraction can be obtained in the direction of expanding and contracting the cylinder diameter (circumferential length) and the cylinder shaft length. This is suitable for fixing the mounting position and facilitating removal.
Here, the “elastic yarn” maintains a contracted state when no tensile force is applied (non-extension = normal state), and freely expands according to the tensile force when a tensile force is applied, and When the tensile force is released and the load is restored when no load is applied, the material is restored (contracted) from the stretched state to the original contracted state.

As a method for mixing elastic yarns, a form selected from at least one of inlay, drawing, plating, knit, knit-in, or composite yarn may be adopted. For elastic yarn, polyurethane or rubber-based elastomer material may be used alone, or covering yarn using polyurethane or rubber-based elastomer material for “core” and nylon or polyester for “cover” can do. By employing such a covering yarn, the garment 200 of the present invention can be provided with functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring. It is also useful for improving the feel (feel) and controlling elongation.

The body fabric body 202 knitted in this manner sufficiently follows the movement of the wearer, and has elasticity to such an extent that it can be stretched and recovered. When the stretchability of the body fabric body 202 causes vertical stretch along the height direction of the wearer and horizontal stretch along the waistline direction of the wearer, the vertical stretch may hinder the movement of the wearer. It has a weak elastic resistance to a certain extent, and in the lateral expansion and contraction, the body body body 202 is completely fitted to the wearer, and a strong elastic force for preventing the slippage is generated, and a strong tightening force is expressed to increase the pressure on the skin surface. Those are preferred.

That is, when the wearer wears, the Y direction (height direction) has a small elastic resistance and easily expands and contracts following the movement of the body, while the elastic resistance is large and hardly stretched in the X direction (trunk direction). It is preferable that the cloth main body 202 is pressed in the Z direction (body) as a result.
In this way, a specific knitting method for knitting a cylindrical fabric that has a strong clamping force because it is relatively easy to stretch in the Y direction and difficult to stretch in the X direction, and presses the body fabric body 202 in the Z direction. For example, a method of performing milling with a covering yarn using polyurethane equivalent to 22 dtex and inlaying about 110 dtex of polyurethane as an insertion yarn can be cited as a method employing a knitting structure of a milling knitting inlay.

Next, the conductive part 203 will be described in detail. The conductive parts 203 are provided in the body cloth body 202 in a state where the same number of contacts (two in the illustrated example) provided in the electronic devices 217 are separated and insulated from each other. It is preferable that the size of each conductive portion 203 is larger than the contact area set for the contacts of the electronic devices 217. Specifically, it is set to a size in which the direction surrounding the torso, neck, legs, arms, or fingers of the wearer is enlarged.

By enlarging the conductive portion 203 in this manner, there is an advantage that reliable conduction with the skin surface of the wearer can be obtained and that the conduction can be reliably maintained even when the wearer moves. The extent of enlargement can be appropriately changed depending on the type of biometric data to be obtained, the arrangement of the conductive surface (contact location with the wearer), and the like.
Needless to say, the planar shape of each conductive portion 203 and the arrangement of the conductive portion 203 with respect to the cloth body main body 202 can be appropriately changed according to the use of the conductive portion 203.

The conductive portion 203 is preferably formed with a knitted structure, a woven structure, or other fiber structure with a conductive yarn, and thus can exhibit conductivity and water permeability. However, it is possible to form the conductive portion 203 with a material having conductivity and water permeability, preferably a flexible material such as a porous resin sheet, a thin porous metal plate, and an ami material using a thin metal wire. it can.

Here, the water permeability required for the conductive portion 203 is between the skin contact surface that comes into contact with the skin surface of the wearer and the exposed back surface that is the surface opposite to the skin contact surface. Refers to the characteristic of passing slowly over a predetermined time. Further, the “water” passing therethrough includes not only liquid but also water vapor (water present as mist).
Metal wires, metal-coated wires, carbon fibers, or the like can be used as the conductive yarn used when the conductive portion 203 is formed with a fiber structure.

As specific examples of the metal component in the metal strand or the metal-coated wire, gold, platinum, silver, copper, nickel, chromium, iron, copper, zinc, aluminum, tungsten, stainless steel and the like are suitable. In addition, pure metals such as titanium, magnesium, tin, vanadium, cobalt, molybdenum, tantalum, and alloys thereof (brass, nichrome, etc.) can be used.
As the metal strand, not only a continuous long wire but also a twisted single wire can be used. On the other hand, when the core material is a resin fiber, wire or animal or plant fiber in a metal-coated wire, a wet coating method or a powder adhesion method can be used, including plating treatment employed in resin plating methods, etc. Good. Further, when the core material is a metal wire, a thermal spraying method, a sputtering method, a CVD method, or the like can be employed. Monofilaments, multifilaments, and spun (spun) yarns may be used as the core material, or wooly processed yarns, covering yarns such as SCY and DCY, and bulky processed yarns such as fluffed yarns may be used.

In addition, these metal wires, metal-coated wires, and carbon fibers may be mixed with non-conductive fibers. For example, a spun (spun) yarn can be used for blended yarn, covering yarn, or assortment. It is also possible to mix with a fiber having a melting point and a softening point higher than the heat setting temperature.
As the knitting structure employed in the conductive portion 203, for example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a change organization thereof (for example, Milan rib, corrugated cardboard knit, Kanoko, pile, etc.) can be employed.

In some cases, it is also possible to employ a structure in which the ground yarn portion serving as the basis of the conductive portion 203 is knitted as a full knit of the various knitting structures and knitted by float knitting on the conductive surface side of the same region. In this case, the float yarn of the float knitting rises beyond the height in the thickness direction due to the knitting structure of the ground yarn. Therefore, the contact of the conductive surface is further ensured with respect to a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. In addition, it will follow even more precise movements of the skin surface. Therefore, reliable conductivity can be obtained.

Next, the pressing urging unit 207 will be described in detail. The pressing urging unit 207 has an urging force that can press the water supply material 206 toward the conductive unit 203 even at the maximum extension caused by the movement of the wearer within the schedule.
The pressing and biasing unit 207, for example, by performing knitting by performing elastic thread insertion, thread switching, knitting structure change, loop length change, or a combination of these operations during knitting of the body fabric body 202, It can be formed integrally with the body cloth body 202.

Specifically, the fiber material and knitting structure forming the pressing and biasing portion 207 are basically the same as those employed for the body fabric body 202 except for the strength of the biasing force. Similarly to the case of the body cloth body 202, the pressing and biasing portion 207 also causes vertical expansion / contraction along the wearer's height direction and lateral expansion / contraction along the wearer's waistline direction. The same applies to the point that the horizontal expansion and contraction is strengthened so that the wearer's waistline can be firmly fitted.

By the way, the “clothing provided with the water-permeable conductive part” according to the present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.
As shown in FIG. 42, the garment 200 of the present invention can be implemented by using an animal (such as a beast) other than a human as a “clothing person”. In this case, the body cloth main body 202 may be connected to the back side of the animal in a cylindrical shape when used, or connected to the ventral side of the animal to form a cylindrical shape. Also, in order to cope with the steep movements found in animals, the region corresponding to the abdomen of the animals should have a fiber structure rich in elasticity.

As shown in FIG. 42, the cloth body main body 202 may have a cylindrical shape, a tapered cylindrical shape, a gourd cylindrical shape, or the like. In these cases, it is not always required to be seamless in the circumferential direction, and it is also possible to form the body cloth main body 202 in a belt shape and wrap it around a target site of the wearer.
In order to maintain the state of wrapping around the wearer, various fastening methods such as string fastening, button fastening, hook fastening, and hook-and-loop fastening can be employed in addition to belt fastening around the circumferential direction. If necessary, an adjustment function for making the circumference (cylinder diameter) at the time of fastening variable may be provided.

The conductive part 203 is a method of sewing (embroidery) conductive thread on a base fabric such as the body cloth main body 202 or the pressing biasing part 207, or printing using conductive ink, conductive silicon, or the like. It can also be formed.
The pressing and biasing portion 207 can also form the pressing and biasing portion 207 by joining a fabric having a strong biasing force knitted separately from the body fabric main body 202 to the body fabric main body 202 by sewing or the like.

The garment 200 of the present invention includes a case where the entire body cloth body 202 is formed by the pressing and biasing portion 207.
The garment 200 of the present invention applies a current from the conductive portion 203 to the skin surface or from the skin surface to the conductive portion 203 while water is present between the conductive portion 203 and the skin surface. This is based on the technical idea of reducing the electrical resistance between the conductive portion 203 and the skin surface. Therefore, it is a preferred embodiment to supply and hold moisture to the conductive portion 203 by the water supply material 206, but the equipment and use of the water supply material 206 are not necessarily indispensable. That is, there may be a case where the water supply material 206 or the like is not used.

For example, a back material (which may be the same as the water stop part 220 described above in terms of material) having low air permeability, air barrier property, heat resistance, water resistance, etc. is at least electrically conductive to the body fabric body 202. If it is provided so as to overlap the back of 203, it leads to inducing stuffiness (sweat) on the skin surface, and this stuffiness may be a source of water supply between the conductive portion 203 and the skin surface. It is even better if the pressing portion 207 presses the conductive portion 203 against the skin surface through such a back material.

However, even in these cases, it is important that the conductive portion 203 has “water permeability between the skin contact surface and the exposed back surface”, and this configuration can retain moisture for a predetermined time (water retention effect). ) Will be obtained.
