Description

  The present invention relates to a garment having a highly conductive contact.

In order to enable stable detection of a biological signal even when violently exercising, conventionally, a plurality of small protrusions are provided on the conductive part itself or the peripheral part of the conductive part to attach the protrusion and the human body. Attempts have been made to increase the frictional resistance with the skin and thereby suppress the side slip (positional deviation) of the conductive part with respect to the human skin (Patent Document 1).
In Patent Document 1, it is described that it is preferable that a plurality of small protrusions are formed so that the cross-sectional shape on the protruding end side is an ellipse or a suction cup. In addition, in this patent document 1, the Example which made the protrusion of a protrusion and the surface of an electroconductive part become the same height, and the Example which mounted the electroconductive protrusion on the electroconductive part are disclosed. Has been.

JP 2016-36642 A

  The conductive portion described in Patent Document 1 has a small contact area with respect to the human skin because the projections are small, and even though the frictional resistance due to the projections is increased, the conductive portion with respect to the human skin is not sufficient. It does not prevent skidding. That is, this conductive part should be premised on generating a strong tightening force (pressing force toward the human skin) that tightens the human skin on the clothes side.

  Nonetheless, if the tightening force of the clothes is excessively increased, the feeling of pressure, the difficulty of movement, and the stuffiness of the human body will be emphasized. Therefore, this becomes a factor, and it becomes difficult to collect the displacement amount of the vital data accompanying the fluctuation of the momentum (load) as accurate (pure) data without disturbance. From this, it is clear that there is an upper limit to the tightening force generated in the clothes.

  If this is the case, a measure of attaching a plurality of small protrusions to the conductive part does not cause a large frictional resistance, and as a result, a sufficient effect of suppressing the side slip of the conductive part on the human skin can be obtained. It's not hard to imagine what you can't do. For example, if it is a light and simple repetitive exercise that is slow enough to walk on a treadmill, even if a certain degree of skid prevention effect can be obtained, intense exercise (eg on a treadmill) When a target is a movement that combines complicated movements such as running and radio exercises, it must be said that it is almost impossible to prevent a side slip of the conductive portion.

  The present invention has been made in view of the above circumstances, and can reliably prevent the movement of the conductive portion with respect to the human skin regardless of the weight and strength of exercise, the variety of operation, etc. It is an object of the present invention to provide a garment having a high-conductivity contact that can be suitably used for, for example, collecting a displacement amount of vital data associated with fluctuations in momentum (load) as pure data.

In order to achieve the above object, the present invention has taken the following measures.
That is, the garment having the highly conductive contact according to the present invention has the conductive part provided on the surface of the body cloth body facing the wearer's skin and the arrangement attached to the outer peripheral part of the conductive part. And an elastic mat provided on a surface of the fabric body directed toward the wearer's skin.

The conductive portion is preferably formed of a fiber structure made of any one of a knitted structure, a woven structure, and a non-woven structure.
The elastic mat is formed of a waterproof forming material, and is formed integrally with a conductive portion supporting portion that partitions the body fabric body and the conductive portion so that they are not in contact with each other. Is preferred.

On the surface of the body cloth body that is directed to the skin of the wearer, the conductive portion is more convex than the elastic mat so that an edge is formed on the outer peripheral portion of the conductive portion. Is preferred.
The elastic mat is preferably formed of an adhesive resin sheet material.
The elastic mat can be formed of polyurethane or silicon.

  Between the conductive part and the body cloth body, a wiring band is provided so as to be in contact with the conductive part, and a waterproof mat formed of a resin sheet material is provided in contact with the body cloth body. It is preferable that a melt-adhesive adhesive layer formed of a resin nonwoven fabric is provided between the conductive portion and the wiring band.

  The garment having a high-conductivity contact according to the present invention can reliably prevent the movement of the conductive part with respect to the human skin regardless of the lightness and strength of exercise, the variety of movement, etc., and is therefore accurate (pure) without disturbance. It can be suitably used for collecting the amount of displacement of vital data associated with fluctuations in the amount of exercise (load) as data.

FIG. 6 is an exploded cross-sectional view illustrating the manufacturing process at the cross-sectional position along the line BB in FIG. 5. It is a top view of the 5th example showing the arrangement relation when the conductive part and the elastic mat are viewed in plan.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 7 show a first embodiment of a garment 1 (hereinafter referred to as “the garment 1 of the present invention”) having a highly conductive contact according to the present invention. For example, as shown in FIG. 1 (FIG. 1 is a cross-sectional view taken along the line AA in FIG. 5), the garment 1 of the present invention is provided on the surface (inner surface) directed toward the wearer's skin with respect to the body body 2. And the elastic mat 4 provided on the surface (also the inner surface) directed to the skin of the wearer with respect to the body cloth body 2 in an arrangement attached to the outer peripheral portion of the conductive portion 3. Is the basic configuration.

  The conductive part 3 is formed such that at least the surface directed to the skin of the wearer has conductivity. On the other hand, whether the elastic mat 4 is conductive or non-conductive is not limited. However, the elastic mat 4 is formed thinner than the conductive portion 3 (in other words, the conductive portion 3 is formed thicker than the elastic mat 4). The portion 3 is more convex than the elastic mat 4. Therefore, the edge 5 by the outer peripheral part of the electroconductive part 3 is formed in the surface facing the wearer's skin in the body cloth main body 2.

  Here, “edge 5” naturally includes the case of “sharp corner”, but it is limited at all whether the corner is an acute angle, a right angle, or an obtuse angle. is not. In addition, there are cases in which minute irregularities or protrusions of fiber ends are mixed in the corners to present “unclear corners”, or “Chamfered corners”. Shall be included.

In short, the “edge 5” of the conductive portion 3 has a state in which a step due to a difference in thickness (height) between the elastic mat 4 and the conductive portion 3 occurs in a portion of the conductive portion 3 adjacent to the elastic mat 4. It shall be said.
As shown in FIG. 5, the wiring band 6 is electrically connected to such a conductive portion 3. These wiring bands 6 have electrical continuity in the longitudinal direction of the band, and are connected to various other devices (not shown) at one end of the body cloth body 2 at the other end, for example. Can do. The wiring band 6 is not limited to be provided integrally with the body cloth body 2 or provided separately.

As device devices, it is possible to employ various measuring devices for collecting electrocardiograms, electromyograms, etc., as well as treatment devices for performing electrical therapy, electromagnetic wave therapy, and the like. It is also possible to use a transmitter / receiver or the like for wirelessly communicating signals with various devices (computers or the like) installed at different locations.
Therefore, according to the selection of the device device or the like, the conductive portion 3 can be used as an electrode for applying current, pulse, magnetism, etc. to the wearer of the garment 1 of the present invention, and various detections can be made. It can also be used as sensors for detecting elements (including the case of detecting a current).

  In the first embodiment, the body fabric body 2 is a T-shirt type upper garment, and a trunk is formed of a seamless tubular fabric in the circumferential direction, and a collar is opened on one side in the tube axis direction. ([Eriaki]: a hole through which the wearer's head passes) 10 is provided, and sleeves 11 are attached to the left and right sides of the collar opening 10. A plurality of conductive portions 3 are arranged on the body fabric main body 2 so as to correspond to the chest of the wearer.

Further, in order to accommodate device devices and the like, a pocket-shaped article accommodating portion 8 and the like are provided in an arrangement close to the hem portion of the body cloth body 2. The pocket-shaped article accommodating portion 8 has advantages that it can prevent vibration, positional deviation, dropout, etc. of the device equipment and the like, and that the device equipment etc. can be easily attached to and detached from the body cloth body 2.
In the garment 1 of the present invention having such a configuration, when the wearer wears it, a tightening force in the waistline direction acts on the body fabric body 2, and this tightening force acts on the conductive portion 3 as a back pressure. As a result, each conductive portion 3 is pressed against the skin of the wearer. However, since the conductive portion 3 has a spread in the surface direction, a surface contact state maintaining an appropriate surface pressure is ensured. It becomes.

  Further, the edge 5 formed on the outer peripheral portion of the conductive portion 3 comes into contact with the wearer's skin so as to exert a lateral shift preventing action (slip prevention), so that the wearer can exercise intensely. Even in the case of performing (such as running on a treadmill or a combination of complex movements such as radio exercises), the conductive portion 3 is surely held in a stopped state against the wearer's skin. It has become. Therefore, the displacement amount of the vital data accompanying the fluctuation of the momentum (load) can be collected as accurate (pure) data without disturbance.

Next, details of the garment 1 of the present invention will be described.
First, the conductive part 3 will be described in detail. The conductive portion 3 can be formed of a fiber structure having any one of a knitted structure, a woven structure, and a non-woven structure. When the knitting structure is adopted, 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 may be obtained by independently knitting to form the conductive portion 3, or obtained by simultaneously knitting a cut boss knitting or the like while the body body 2 is being knitted. Also good.
In some cases, the portion of the ground yarn that is the basis of the conductive portion 3 is knitted as a full knit of the various knitting structures described above, and braided by float knitting on the conductive surface side of the same region (the surface that contacts the skin of the wearer) It is good also as what makes the electroconductive part 3 knitting by employ | adopting the structure to perform.

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 portion 3 with the wearer's skin is further ensured with respect to the three-dimensional and complicated curved surface, unevenness, flexible portion, etc. existing on the wearer's skin. Also, it will follow the complex movements and fine movements of the skin more accurately. Therefore, the conductivity can be further ensured.

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.
The yarn forming the conductive portion 3 employs a metal wire, a metal-coated wire, carbon fiber, or the like when causing the conductive portion 3 to be conductive.

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.
When the conductive part 3 is knitted using conductive yarn, the end of the conductive yarn may appear on the conductive surface (the surface in contact with the skin of the wearer). Therefore, it is preferable that the conductive portion 3 after knitting is subjected to a fraying prevention process using a heat sealing material or a heat bonding material.

  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 It can be prevented from floating. At the same time, since the welding marks of the heat fusion material or the heat fusion material are dispersed on the conductive surface of the conductive portion 3, this is a grip effect. That is, this grip effect has a synergistic effect with the edge 5 to further strengthen the lateral displacement prevention action (slip prevention) of the conductive portion 3 with respect to the wearer's skin, and the stop state with respect to the wearer's skin is enhanced. It becomes like this.

In addition, since the fraying treatment is performed, a so-called “cutting” action (an effect of using a portion cut with scissors or a cutter as it is untreated) can be obtained, so the size and shape of the conductive portion 3 can be arbitrarily set. It also leads to the advantage of being able to change.
Next, the elastic mat 4 will be described in detail. The elastic mat 4 may be formed of rubber or resin sheet material or the like, or, as described with respect to the conductive portion 3, a fiber structure made of any one of a knitted structure, a woven structure, and a non-woven structure. It may be formed. When the elastic mat 4 is formed of rubber or a resin sheet material, it is advantageous in that the feel of the wearer can be improved, and itching and pain can be suppressed as much as possible.

When selecting the material for forming the elastic mat 4, it can be determined that the surface of the elastic mat 4 has a higher frictional resistance than the surface of the conductive portion 3. That is, by adopting the elastic mat 4 having a large frictional resistance, the lateral displacement prevention action (slip prevention) of the conductive portion 3 with respect to the wearer's skin is strengthened, and the stop state with respect to the wearer's skin is further increased.
As an element for increasing the frictional resistance of the elastic mat 4, it is preferable to select one having a rough surface roughness. In addition, measures such as making the elasticity in the thickness direction rich when the surface roughness is rough, and making the elasticity in the thickness direction strong (hard) when the surface roughness is fine are also effective.

  In the case where the elastic mat 4 is formed of a fiber structure, there is also a method of increasing the frictional resistance (grip effect) by intentionally exposing the elastic yarn on the surface and then performing a heat setting treatment. 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.

Furthermore, if the elastic mat 4 is formed of a resin sheet material, it is preferable to employ an adhesive resin sheet material as a material. Specifically, the elastic mat 4 can be formed of a polyurethane or silicon sheet.
Thus, the material for forming the elastic mat 4 is not particularly limited. In some cases, between the elastic mats 4 arranged corresponding to one conductive portion 3 (refer to the description related to FIGS. 1 to 3 for the cross-sectional structure, and refer to the description described later for FIG. In addition, the elastic mat 4 used at one place is not limited in that it is made of the same material as a whole or can obtain equivalent or homogeneous characteristics.

For example, it is possible to mix a resin sheet and a fiber structure, to make a composite that combines materials having different degrees of elasticity, friction resistance, etc., or to make a composite that combines materials having different melting points. . Moreover, these mixed use and combined use may be implemented as a planar arrangement or in the thickness direction.
As described above, the elastic mat 4 is relatively thinner than the conductive portion 3 so that the conductive portion 3 is convex.

  The arrangement of the elastic mat 4 with respect to the conductive portion 3 is such that the outer periphery of the conductive portion 3 is surrounded by the elastic mat 4 including the four corners as in the first example shown in FIG. As in the second example shown in FIG. 4 (b), the elastic mat 4 is arranged so as to snuggle up to the entire circumference excluding the four corners of the outer circumference of the conductive part 3, or the third example shown in FIG. 4 (c). As an example, an example in which the elastic mat 4 is placed close to only one set of opposite sides of the outer periphery of the conductive portion 3 can be given.

In the first example shown in FIG. 4A and the second example shown in FIG. 4B, a strong grip force is generated when a load is applied to the conductive portion 3 from any direction in the plane direction. There are advantages you can do. With regard to this advantage, it can be said that the first example is the optimum example.
In the third example shown in FIG. 4C, a strong grip force is generated when a load is applied in the direction in which the elastic mat 4 is distributed at the center of the conductive portion 3 (the left-right direction in FIG. 4C). It can be said that it is a possible structure.

The area ratio of the elastic mat 4 to the conductive portion 3 is
[Conductive part] / [Elastic mat] <1
By satisfying the relationship, it is preferable that the gripping force is strong and the characteristic that it is difficult to be affected by moisture contained in the body fabric body 2 can be obtained.
In addition, it is good also as arrangement | positioning which makes the elastic mat 4 snuggle up only in one side part among the outer periphery of the electroconductive part 3, or only adjacent two side parts (L shape etc.). However, the conductive portion 3 is not limited to exhibiting a quadrangle in a plan view, and may be a circle, an ellipse, an oval, or a polygon other than a quadrangle in a plan view. The elastic mat 4 may be arranged so that it is close to at least one of the outer circumferences of the three.

  Furthermore, as in the fourth example shown in FIG. 4D, it is possible to adopt an arrangement in which the elastic mat 4 is brought close to the outside while the gap 15 is generated in the outer peripheral portion of the conductive portion 3. By doing so, it is expected that a part of the skin of the wearer is sandwiched in the gap 15 and inevitably an effect of increasing the frictional resistance. The anti-slip action (slip prevention) of 3 is strengthened.

In this fourth example, it can be said that it is also advantageous in that a strong grip force can be obtained without impairing the air permeability and hydrophilicity of the conductive portion 3.
FIG. 2 is an example in which a conductive portion support portion 16 is provided to partition the body fabric body 2 and the conductive portion 3 and make them non-contact. The conductive portion support portion 16 can be formed as a separate member from the elastic mat 4 or can be formed integrally with the elastic mat 4. Needless to say, when the conductive portion support 16 and the elastic mat 4 are integrally formed, the conductive portion support 16 is made of the same material as the elastic mat 4. Here, the elastic mat 4 is preferably formed of a forming material having waterproofness.

FIG. 3 shows an example in which the gap 15 is generated in the outer peripheral portion of the conductive portion 3 as described with reference to FIG.
In addition, when acquiring a vital signal at a short distance (for example, when collecting electromyogram data), as shown in FIG. For example, two) may be provided. In this case, in order to prevent the conductive parts 3 from being short-circuited due to sweat or the like, it is preferable to select a material having waterproof performance (for example, a sheet of silicon, polyurethane, etc.) as the elastic mat 4.

Next, the body body 2 will be described in detail. The body cloth main body 2 is formed of a non-conductive fiber material in principle (at least the insulating region centered on the arrangement portion of the conductive portion 3). In addition, the shape of the body cloth main body 2, the arrangement | positioning of the electroconductive part 3 with respect to this body cloth main body 2, cross-sectional structure, etc. are not specifically limited.
In the case where the body 2 is knitted with a non-conductive fiber material, specific examples of the fiber material include synthetic fibers (for example, polyester fiber and nylon fiber), natural fibers, and a mixture of synthetic fibers and elastic yarns. Etc.

  Further, when the body fabric body 2 is formed by knitting, the knitting structure to be adopted 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.
The “elastic yarn” maintains a contracted state when no tensile force is applied (non-elongation = normal state), and freely expands according to the tensile force when a tensile force is applied. A material that restores (shrinks) from the stretched state to the original contracted state when the tensile force is released and returned when no load is applied.

  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 adopting such covering yarn, functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring can be imparted to the body fabric body 2. 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 completely 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. Is 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 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, in the case where the conductive portion 3 is uniquely formed, a method for attaching to the body cloth body 2 will be described. For this attachment method, an appropriate method such as adhesion with an adhesive, heat fusion with a thermoplastic resin, sewing with a sewing machine, or engagement with a surface fastener can be adopted.
In addition, when providing the wiring belt | band | zone 6 (refer FIG. 5) between the electroconductive part 3 and the cloth body main body 2, as shown in FIG. 6, the waterproof mat 20 is provided by arrangement | positioning contact | abutted to the cloth body main body 2, The wiring band 6 is preferably stacked on the waterproof mat 20, and the elastic mat 4 is preferably stacked thereon. A hole 21 corresponding to the conductive portion 3 is formed in the elastic mat 4. In this case, the elastic mat 4 and the waterproof mat 20 may be made of, for example, a resin sheet made of polyurethane or the like as a forming material and heat-adhered.

Since the resin sheet such as polyurethane is waterproof after being heated, there is an advantage that the wiring band 6 can be prevented from being short-circuited, leaked, or corroded due to sweating of the wearer.
A hole 21 formed in the elastic mat 4 is provided with a melting adhesive layer 22 in order to maintain the electrical connection between the conductive portion 3 and the wiring band 6 and to strengthen the adhesive force.
The material for forming the waterproof mat 20 is not particularly limited. In some cases, the waterproof mat 20 disposed in correspondence with the conductive portion 3 is not limited in that the entire waterproof mat 20 is made of the same material, or an equivalent or homogeneous characteristic is obtained.

  For example, it is possible to make a composite that combines materials with different degrees of elasticity or the like, or to make a composite that combines materials with different melting points. Further, these combined uses may be implemented as a planar arrangement or in the thickness direction. In addition, when using the composite in the thickness direction, as long as at least one layer in the stack is waterproof, the other layers are non-waterproof.

FIG. 7 shows a method of pressing the conductive portion 3 and the wiring band 6 using the melting-bonding adhesive layer 22. In this overstretching pressure method, a non-woven fabric patch 22a formed of a thermoplastic resin such as polyurethane is overlaid on the hole 21 of the elastic mat 4 in an overlapped state or a fitted state.
Then, the waterproof mat 20, the wiring band 6, the elastic mat 4, the nonwoven fabric patch 22 a, and the conductive part 3 are all overlaid on the body fabric body 2 and pressed in the thickness direction. And it heats until the thermoplastic resin contained in the nonwoven fabric patch 22a with each of the elastic mat 4 and the waterproof mat 20 is softened.

  By doing in this way, while the elastic mat 4 and the waterproof mat 20 wrap the clothing 1 of the present invention, an adhesive force to the body fabric body 2 is generated at the same time. Further, when the thermoplastic resin contained in the nonwoven fabric patch 22a is softened, the elastic mat 4 is entangled with each other, and the conductive portion 3 and the wiring band 6 are bonded in an electrically conductive state. The non-woven patch 22a forms the melt-adhesive adhesive layer 22 by cooling. Since the melt-adhesive adhesive layer 22 has a structure including many rough voids, the conductive portion 3 and the wiring are made of softened thermoplastic resin. An insulating film is not formed between the band 6 (impeding conductivity).

  Note that the connection between the conductive portion 3 and the wiring band 6 is not limited to the application of the above-described superposition heating method. For example, a sewing method using a sewing machine or hand-sewing can be exemplified. In this case, by using the same type of thread as described above for the knitting of the conductive portion 3 as the sewing thread, the conductivity can be further improved. In addition, there is an advantage that the connection strength can be increased as compared with the case of the adhesive structure.

  As is apparent from the above description, when the wearer wears the garment 1 (cloth body body 2) of the present invention, the conductive portion 3 comes into surface contact with the skin of the wearer reliably. In addition, the conductive portion 3 has an effect of preventing lateral displacement (slip prevention) on the skin of the wearer by the edge 5 or the like formed on the outer peripheral portion of the conductive portion 3. Therefore, when collecting data such as an electrocardiogram and an electromyogram, the current waveform can be satisfactorily taken out from the conductive part 3 brought into contact with the skin of the wearer, and when performing electric therapy, electromagnetic wave therapy, etc. The current can be satisfactorily applied to the skin of the wearer through the conductive portion 3.

In other words, the movement of the conductive part relative to the human skin can be reliably prevented regardless of the lightness and strength of movement, the variety of movements, etc., and as a result of accurate (pure) data without disturbance, vitals associated with fluctuations in momentum (load) It can be suitably used for collecting the amount of data displacement.
In addition, in the garment 1 of the present invention, when the conductive portion 3 is formed of a fiber structure, a sweat absorbing action from the skin of the wearer can be obtained due to the hydrophilicity (water absorption) of the fiber structure. become. Therefore, the advantage that the conductivity between the conductive portion 3 and the skin becomes higher as the wearer sweats due to exercise or the like.

In addition, since the fiber structure has a characteristic of high air permeability, it can perform a breathing action as a flow of air and temperature through the conductive portion 3, and the wearer does not feel a sense of stuffiness (increasing exercise). The advantage is that disturbances are less likely to be added to the accompanying changes in vital data.
These sweat-absorbing action and breathing action in the energizing part 3 are more convex than the elastic mat 4 where the conductive part 3 snuggles up to the outer peripheral part (the standing surface is generated in the outer peripheral part (edge 5) of the energizing part 3). ) Is also a favorable condition and will occur efficiently.

By the way, the present invention is not limited to the above-described embodiments, and can be further appropriately changed according to the embodiments.
For example, 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 torso, neck, arms, fingers, legs, etc. of the wearer. Further, 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 band shape and wound around the target site of the wearer. In order to maintain the winding state, it is possible to adopt various fastening methods such as strap fastening, button fastening, hook fastening, hook-and-loop fastening, wire fastener fastening, sewing, etc. is there. If necessary, an adjustment function for making the circumference (cylinder diameter) at the time of fastening variable may be provided.

The conductive portion 3 has been described in detail mainly in the case of a knitted structure, but a woven structure may be used. In addition to the woven fabric structure, it can be formed of a non-woven fabric or a resin sheet (utilization of a stretchable resin sheet or a conductive resin sheet).
