Abstract

PROBLEM TO BE SOLVED: To provide a glove with a strain sensor, hardly giving discomfort to a wearer and easy to accurately acquiring the movement of wearer's fingers.SOLUTION: This glove with a strain sensor includes: a glove body applied to a wearer's hand; and one or two or more sheet-like strain sensors attached to the glove body and stretched according to the deformation of the glove body. Thus, when the strain sensors are stretched following the deformation of the glove body, a detection signal is sent from the strain sensors so that the movement of wearer's hand can be recognized. Therefore, differently from the conventional glove with a compression type sensor, the movement of the hand can be precisely sensed from stretching. Further, since the compression type sensor of the conventional glove is not provided, it is not necessary to dispose any strain sensor between a material to be gripped such as a golf club and the hand, so that the sensor can be installed in a portion hard to give discomfort to a wearer and natural movement of wearer's hand can be sensed.

Description

  The present invention relates to a glove with a strain sensor.

  As a glove provided with a strain sensor, a sport glove such as a golf glove provided with a strain sensor whose resistance changes according to displacement is known (see Japanese Patent Laid-Open No. 10-286338). This sports glove grasps the movement of the hand during the swing of a golfer who is a wearer by sensing pressure with a sensor.

  However, in the conventional glove, since a sensor exists between the grip of the golf club and the hand when the glove is worn, the wearer feels uncomfortable. For this reason, there exists a possibility that the movement of the hand at the time of wearing the general glove which does not have a sensor cannot be grasped correctly. In addition, the conventional glove grasps the movement of the hand by sensing the pressure, and the movement of the finger is only estimated by the sensed pressure, and the movement of the hand is not accurately captured. There is a fear.

JP-A-10-286338

  This invention is made | formed based on such a situation, and the subject of this invention is to give a wearer a sense of incongruity, and to provide the glove with a strain sensor which is easy to catch a wearer's hand movement accurately. is there.

The glove with a strain sensor according to the present invention, which was made to solve the above problems,
A glove body that can be worn on the wearer's hand;
And a sheet-shaped strain sensor that is attached to the glove body and expands and contracts following the deformation of the glove body.

  When the strain sensor is expanded or contracted following the deformation of the glove body, the strain sensor has a detection signal transmitted from the strain sensor. Based on the detection signal, the glove body is deformed, that is, the wearer's hand. The movement can be recognized accurately. Moreover, since the glove with a strain sensor is not a compression sensor like a conventional glove, there is no need to dispose a strain sensor between a gripped object such as a golf club and a hand, and the wearer feels uncomfortable. Since it can be installed in places that are difficult to give, it is possible to sense the natural hand movement of the wearer.

  It is preferable that the glove with a strain sensor further includes a wiring portion provided integrally with the glove body and electrically connected to the strain sensor. Thus, since the wiring part is provided integrally with the glove body, the wiring part is less likely to interfere with the movement of the hand that deforms the glove body.

  The glove with a strain sensor is preferably configured to be attachable to and detachable from the glove body and electrically connected to the wiring portion, and further includes a transmission module that transmits a detection signal of the strain sensor. As a result, the detection signal of the strain sensor can be transmitted to the external device via the transmission module. Therefore, the movement of the hand can be accurately grasped by determining the detection signal in the external device. Further, since the transmission module is detachably provided on the glove body, the transmission module can be detached from the glove body when the strain sensor glove is not used.

  The attachment location of the strain sensor is preferably a site other than the palm-side surface of the glove body and a joint-corresponding site. Thus, the discomfort given to the wearer can be further reduced by attaching the strain sensor to a portion other than the palm-side surface of the glove body. Further, by attaching the strain sensor to the joint-corresponding portion, it is possible to accurately detect the movement of the hand at the wearer's joint.

  The “part other than the surface on the palm side of the glove body” means a surface on the back side of the hand of the glove body and a part (side surface part) between the palm and the back of the hand. Further, the “joint-corresponding portion” means a portion where a joint of a general wearer (a wearer having a hand size expected to wear the size of the glove) is located.

  As described above, in the glove with a strain sensor of the present invention, the strain sensor can detect the movement of the hand by expansion and contraction. Therefore, the wearer does not feel uncomfortable and the movement of the wearer's hand can be accurately captured.

It is a schematic front view of the glove with a strain sensor concerning one embodiment of the present invention. It is a schematic explanatory drawing explaining the electrical connection of the glove with a strain sensor of FIG.

  Hereinafter, an embodiment of a glove 1 with a strain sensor according to the present invention will be described. First, as an embodiment, a golf glove with a strain sensor (sports glove 1 with a strain sensor) is taken as an example and referring to FIGS. I will explain.

Here, five finger equivalent portions 3c are provided corresponding to each finger. More specifically, as the finger equivalent part 3c, a thumb accommodating part capable of accommodating a thumb, an index finger accommodating part capable of accommodating an index finger, a middle finger accommodating part capable of accommodating a middle finger, a ring finger accommodating part capable of accommodating a ring finger part, and A little finger accommodating portion capable of accommodating the little finger is provided.

  The glove body 3 is formed by sewing a flexible cloth-like body. For this reason, the glove body 3 is provided to be deformable. Moreover, the glove body 3 is composed of a cloth-like body that can be expanded and contracted so as to give the wearer a fit when worn.

  The cloth body of the glove body 3 may have a single layer structure made of a single cloth, or may have a multilayer structure in which a large number of cloths are laminated. Here, as a cloth constituting the cloth body of the glove body 3, a woven fabric, a knitted fabric, a resin or rubber sheet, a nonwoven fabric, or the like can be appropriately employed. Especially, it is preferable that the cloth body of the glove body 3 is made of a material that does not have conductivity, and the glove body 3 preferably does not have conductivity.

(Strain sensor 5)
A plurality of the strain sensors 5 are attached to the glove body 3. In this embodiment, the strain sensor 5 attached to the wrist equivalent part 3a of the glove body 3 and the strain sensor 5 attached to the finger equivalent part 3c of the glove body 3 are provided. The strain sensor 5 attached to the finger equivalent portion 3c includes a strain sensor 5 attached to the ring finger storage portion and a strain sensor 5 attached to the middle finger storage portion.

  Each of the strain sensors 5 is attached to the glove body 3 at a portion other than the palm-side surface of the glove body 3. Specifically, any strain sensor 5 is attached to the back side surface of the glove body 3.

  Each of the strain sensors 5 is attached to a joint-corresponding portion of the glove body 3. The strain sensor 5 attached to the wrist equivalent portion 3a is attached to the glove body 3 at a portion corresponding to the wrist joint where the wearer's wrist joint (flexible carpal joint) abuts. Specifically, the strain sensor 5 is arranged so as to straddle the wrist joint equivalent part from the opening side of the wrist joint equivalent part and the fingertip side of the wrist joint equivalent part (intercarpal joint equivalent part and carpal middle wrist joint). It is attached to the glove body 3 up to the corresponding part).

  Further, the strain sensor 5 attached to the finger equivalent portion 3c is attached to the glove body 3 at a proximal interphalangeal joint equivalent portion (a portion corresponding to a joint close to the wrist among the finger joints). . Specifically, the strain sensor 5 attached to the ring finger storage portion is equivalent to the joint between adjacent phalanges from the wrist side of the joint corresponding to the joint between adjacent phalanges so as to straddle the part corresponding to the joint between adjacent phalanges. It is attached to the glove body 3 from the part to the fingertip side. Similarly, the strain sensor 5 attached to the middle finger accommodating portion is connected to the proximal interphalangeal joint equivalent portion from the wrist side relative to the proximal phalangeal joint equivalent portion so as to straddle the proximal phalangeal joint equivalent portion of the middle finger. Is attached to the glove body 3 up to the fingertip side. The strain sensor 5 attached to the finger equivalent part 3c has an end on the wrist side that does not reach the part corresponding to the metacarpophalangeal joint, and is located between the part corresponding to the metacarpophalangeal joint and the part corresponding to the joint between adjacent phalanges. It is preferable that the end on the fingertip side does not reach the joint corresponding to the distal interphalangeal joint, but is positioned between the distal interphalangeal joint equivalent and the proximal interphalangeal joint equivalent. It is preferable. Thereby, the distortion sensor 5 of the finger | toe equivalent part 3c can detect the bending | flexion of the finger in an adjacent interphalangeal joint equivalent part more correctly.

  The strain sensor 5 is attached to the outer surface of the glove body 3, whereby the strain sensor 13 is integrally attached to the fabric body 11. The means for integrally attaching the strain sensor 13 to the glove body 3 is not limited to sticking. For example, a strain sensor may be sewn on the glove body or a strain sensor may be laminated on the glove body as appropriate. Is possible.

  Here, it is preferable that the strain sensor 5 is attached by an elastic adhesive. This elastic adhesive preferably has an elastic modulus after curing of 1 MPa or more and 10 MPa. If the elastic modulus of the cured elastic adhesive exceeds the above upper limit, the deformation of the glove body 3 is hindered by the layer in which the elastic adhesive is cured, which may give the wearer an uncomfortable feeling. On the other hand, when the elastic modulus is less than the lower limit, the deformation of the glove body 3 is absorbed by the layer made of the elastic adhesive, and may not be accurately transmitted to the strain sensor 5.

  The strain sensor 5 is attached to the glove body 3 so as to follow the deformation of the glove body 3. Specifically, the strain sensor 13 has stretchability, and is attached to the stretchable glove body 3 so that the strain sensor 13 stretches as the glove body 3 stretches. Yes. It is also possible to provide the strain sensor 13 so as to expand and contract in accordance with the deformation of the glove body 11 by fixing the strain sensor 13 to the glove body at least at both ends (for example, pasting, sewing, etc.). The strain sensor 5 transmits an electrical signal (detection signal) to the wiring unit 9 according to expansion and contraction. As the strain sensor 5, a CNT strain sensor 5 using carbon nanotubes (hereinafter sometimes referred to as CNT) is preferably used. The CNT strain sensor 5 includes a substrate attached to the glove body 3, a CNT film provided on the surface side of the substrate, a pair of electrodes respectively disposed at ends of the CNT fibers, and the CNT And a protective part for protecting the film.

  The substrate of the CNT strain sensor 5 is composed of a flexible plate. The size of the substrate is not particularly limited, and for example, the thickness can be 10 μm to 5 mm, the width can be 1 mm to 5 cm, and the length can be 1 cm to 20 cm.

  The material of the substrate is not particularly limited as long as it has flexibility, and examples thereof include synthetic resin, rubber, non-woven fabric, deformable shape or material metal or metal compound, and the like.

  Examples of the synthetic resin include phenol resin (PF), epoxy resin (EP), melamine resin (MF), urea resin (urea resin, UF), unsaturated polyester resin (UP), alkyd resin, polyurethane (PUR), Thermosetting polyimide (PI), polyethylene (PE), high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE), polypropylene (PP), polyvinyl chloride (PVC), polyvinylidene chloride, Polystyrene (PS), polyvinyl acetate (PVAc), acrylonitrile butadiene styrene resin (ABS), acrylonitrile styrene resin (AS), polymethyl methacrylate resin (PMMA), polyamide (PA), polyacetal (POM), polycarbonate (PC) , Degeneration Polyphenylene ether (m-PPE), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), and cyclic polyolefin (COP) and the like.

  Examples of the rubber include natural rubber (NR), butyl rubber (IIR), isoprene rubber (IR), ethylene / propylene rubber (EPDM), butadiene rubber (BR), urethane rubber (U), and styrene / butadiene rubber (SBR). , Silicone rubber (Q), chloroprene rubber (CR), chlorosulfonated polyethylene rubber (CSM), acrylonitrile butadiene rubber (NBR), chlorinated polyethylene (CM), acrylic rubber (ACM), epichlorohydrin rubber (CO, ECO), Fluoro rubber (FKM), PDMS, etc. can be mentioned. Among these rubbers, natural rubber is preferable from the viewpoint of strength.

  The electrode is not particularly limited, but is formed by applying a conductive elastic adhesive. In addition, it is also possible to use metals, such as copper, for this electrode, and when it is a metal electrode, it is preferable that a shape is a mesh form.

  The CNT film has a rectangular shape in front view. The electrodes are connected to both ends of the CNT film in the longitudinal direction. Further, the carbon nanotube film has a plurality of CNT fibers oriented in one direction (a direction different from the direction of a straight line connecting a pair of electrodes). Thus, when the CNT fibers are oriented and strain is applied in the direction in which the pair of electrodes are separated (when the CNT film is stretched), the contact condition between the CNT fibers changes, and the strain sensor 513 acts as a resistance. Change can be obtained. In order to detect strain more efficiently, the CNT film preferably has a CNT fiber oriented in a direction substantially perpendicular to the arrangement direction of the pair of electrodes (the direction of a straight line connecting the pair of electrodes), preferably in the perpendicular direction. Good to be.

  Each CNT fiber can be composed of a plurality of CNT single fibers. Here, the CNT single fiber means one long CNT. In addition, the CNT fiber has a connection portion where the ends of the CNT single fibers are connected to each other. The CNT single fibers are connected in the longitudinal direction of these CNT single fibers. Thus, in the CNT film, by using the CNT fiber formed by connecting the CNT single fibers in the longitudinal direction, a CNT film having a wide width in the alignment direction of the CNT fiber can be formed. The resistance value of the film can be lowered, and variations in the resistance value can also be reduced.

  The plurality of CNT fibers form a network structure. Specifically, the plurality of CNT fibers are connected or in contact with each other by a connecting portion or the like. At this time, at the connecting portion, the ends of three or more CNT single fibers may be combined, or the ends of two CNT single fibers and an intermediate portion of another CNT single fiber as in the connecting portion. It may be bonded. When a plurality of CNT fibers form such a network structure, the CNT fibers are in close contact with each other, and the resistance of the CNT film can be reduced.

  At this time, the CNT fibers can function as a doubly supported beam structure by connecting or contacting neighboring CNT fibers with the connecting portion as a main base point. The connection between the CNT fibers means that the connection portion and the CNT fibers are electrically connected to each other, and the case where the portions other than the connection portion of the CNT fibers are electrically connected is also included in the connection. The contact between the CNT fibers means that the CNT fibers and the CNT fibers are in contact with each other but are not electrically connected to each other, and the portions that are not the CNT fiber connection parts are in contact with each other but are not electrically connected to each other. Is also included in the contact. A CNT fiber that functions as a doubly supported beam has a large spring constant. Therefore, the CNT fiber has a structure that hardly stretches in the direction perpendicular to the orientation direction (longitudinal direction of the CNT film). Therefore, the rigidity of the CNT film becomes stronger in the direction perpendicular to the orientation direction of the CNT fibers (longitudinal direction of the CNT film), and the CNT strain sensor 5 is sensitive to the strain in the longitudinal direction of the CNT film. It can be detected and the linearity can be further improved. In addition, the connection part of a CNT fiber becomes a main base point, and it may connect or contact with the CNT fiber of the place which not only between adjacent CNT fibers but jumped some. As described above, if the CNT film has a complex network-like CNT fiber, the resistance value becomes lower, and the strain sensor 5 having a high rigidity in a direction perpendicular to the CNT fiber can be obtained.

  The CNT fiber is in a state where each CNT single fiber is substantially oriented in the longitudinal direction of the CNT fiber and is not twisted. By using such a CNT fiber, the uniformity of the CNT film can be enhanced and the linearity as the strain sensor 5 can be enhanced.

  In addition, in the said connection part, each CNT single fiber is couple | bonded by the intermolecular force. For this reason, even when a plurality of CNT fibers are connected in a mesh shape by the connecting portion, an increase in resistance due to the presence of the connecting portion is suppressed.

  The size of the CNT film is not particularly limited. For example, the width (length in the short direction) of the CNT film is preferably in the range of 1 mm to 10 cm, more preferably 1 cm to 5 cm. Can do. By making the width of the CNT film relatively large, the resistance value of the CNT film can be lowered, and variations in the resistance value can also be reduced.

  Although it does not specifically limit as thickness of a CNT film | membrane, For example, as a minimum of the average thickness of a CNT film | membrane, 1 micrometer is preferable and 10 micrometers is more preferable. On the other hand, the upper limit of the average thickness of the CNT film is preferably 5 mm, and more preferably 1 mm. If the average thickness of the CNT film is less than the lower limit, it may be difficult to form such a thin film, or the resistance may increase excessively. On the contrary, when the average thickness of the CNT film exceeds the upper limit, the stretchability may be lowered, the sensitivity to the stretch may be lowered, and the wearer may be uncomfortable.

  Note that the CNT film may have a single-layer structure in which CNT fibers are arranged substantially in parallel in a planar shape, or may have a multilayer structure. However, in order to ensure a certain degree of conductivity, a multilayer structure is preferable.

  As the CNT fiber, either single-walled single-wall nanotubes (SWNT) or multi-walled multi-wall nanotubes (MWNT) can be used, but MWNT is preferable from the viewpoint of conductivity and heat capacity, and the diameter is 1.5 nm. More preferably, the MWNT is 100 nm or less.

(Transmission module 7)
The transmission module 7 is attached to the glove body 3. The transmission module 7 is disposed in a place where it does not interfere with the wearer, and is attached to a part corresponding to the trunk of the hand on the back side of the hand, for example.

  The transmission module 7 is attached to the glove body 3 so as to be detachable. In addition, although the means to attach this detachably is not specifically limited, For example, a hook-and-loop fastener etc. are employable. As described above, the transmission module 7 is detachably provided on the glove body 3 so that the glove body 3 can be easily and reliably washed with the transmission module 7 removed.

  The transmission module 7 includes a power source 7a (battery), a transmission unit 7b, and a processing unit 7c. The transmission unit 7b transmits the detection signal received via the wiring unit 9 to the external device by wireless communication. The processing unit 7c performs a process of determining the detection signal received via the wiring unit 9, and transmitting the detection signal after the determination is performed by the transmission unit 7b. In addition, it is also possible to employ | adopt the structure which has the memory | storage means in which the said glove 1 with a strain sensor accumulate | stores the detection signal received via the wiring part 9. FIG.

(Wiring part 9)
The wiring part 9 has a plurality of pairs for electrically connecting a plurality of strain sensors 5 and the transmission module 7. In the present embodiment, as shown in FIG. 2, the transmission module 7 and the pair of wiring sensors 9 that connect the two strain sensors 5 of the finger equivalent portion 3c in series are provided. And a pair of wiring portions 9 that connect one strain sensor 5 of the wrist equivalent portion 3a. The electrical connection between the plurality of strain sensors 5 and the transmission module 7 is not limited to the above connection, and all the strain sensors 5 may be connected in series, or all the strain sensors 5 may be connected in series. This is also an item that can be appropriately changed in design.

  The wiring part 9 is attached to the glove body 3, and the wiring part 9 is attached to the glove body 3 integrally. Specifically, the wiring part 9 is composed of a conductive thread (thread-like body) sewn on the glove body 3.

  As the yarn constituting the wiring portion 9, a conductive yarn having conductivity is used. As the conductive yarn, a metal conductive yarn such as iron can be used, and a stainless steel thread is preferably used as the metal conductive yarn. According to the stainless steel thread, the electric resistance is small, and even when the glove body 3 is washed, there is an advantage that the change in the electric resistance is relatively small. In addition, as a thread | yarn which comprises this wiring part 9, it is also possible to use the thread | yarn which apply | coated the electrically conductive material to the insulating thread | yarn, and the thread | yarn formed by mixing electroconductive material.

  The yarn constituting the wiring portion 9 preferably has an electric resistance per 10 cm of less than 100Ω, and more preferably less than 50Ω. Thereby, the electrical resistance of the wiring part 9 can be reduced, and the detection signal from the strain sensor 5 can be accurately transmitted to the transmission module 7. The “resistance value per 10 cm” is a resistance value between 10 cm of the yarn when a voltage of 5 V is applied, and can be measured using a general-purpose tester.

  The wiring part 9 has elasticity and is provided to deform following the deformation of the glove body 3. Specifically, the wiring part 9 is formed by stretching and sewing a conductive thread. In addition, stretchable stitching is defined as “JIS B 9003” as “sewing so that when a stretchable fabric is sewed, the stitches are not cut or loosened due to the expansion and contraction of the fabric”. means. Specifically, the wiring part 9 of the present embodiment can be formed by cover stitch (single-sided decorative stitching) or the like.

<Advantages>
In the glove with a sensor 1 having the above-described configuration, when the glove body 3 is deformed and the strain sensor 5 is expanded or contracted by the wearer's operation, the strain sensor 5 sends a detection signal to the transmission module 7 via the wiring portion 9. Transmitting and receiving the detection signal, the transmission module 7 transmits the detection signal to the external device. For this reason, the movement of the wearer's hand can be detected by determining the detection signal in the external device.

  In particular, the sensor-equipped glove 1 uses a detection signal based on expansion and contraction instead of a compression sensor as in the conventional glove 1, and therefore senses the movement of the hand more accurately and accurately than in the case of compression. Can do. In addition, since the strain sensor 5 is attached to the glove body 3 with an elastic adhesive, the glove body 3 can be accurately deformed by the wearer's action, and the strain sensor 5 can be expanded and contracted accurately.

  Further, the strain sensor 5 of the glove 1 with the strain sensor is attached to a portion other than the palm side of the glove body 3 and is not located between the golf club (gripping object) and the hand, so that it is difficult for the wearer to feel uncomfortable. Therefore, a normal golf swing can be performed, and the movement of the hand in the normal golf swing can be accurately grasped.

  In particular, since a CNT sensor having a CNT film is used as the strain sensor 5, the thickness can be reduced as compared to other strain sensors 5, and the sensitivity and responsiveness can be increased, and the wearer can feel less uncomfortable. The movement of the hand can be grasped accurately and accurately.

  Further, since the strain sensor 5 is attached to the joint-corresponding portion, it is possible to accurately grasp the movement of the hand at this joint. In particular, if the strain sensor 5 is attached to the portion corresponding to the wrist joint, it is possible to accurately detect the movement of the wearer's wrist. In particular, since the movement of the wrist during the golf swing can be accurately grasped, it is possible to easily and surely recognize how much the wearer's wrist cock is made.

  Furthermore, if the strain sensor 5 is attached to the portion corresponding to the joint between adjacent phalanges of the finger equivalent part 3c, it is possible to easily and reliably determine how to use the finger joint when gripping the object to be grasped. In particular, since the movement of the finger can be accurately grasped during the golf swing, it is possible to easily and reliably recognize how the golf club is gripped at the moment of impact after the wearer holds the ball. it can. In the above embodiment, since the strain sensor 5 is attached to the ring finger storage portion and the middle finger storage portion, it is possible to accurately grasp the movement of the important finger when gripping the golf club, and more reliably the golf club. The grasping state can be grasped.

  Moreover, since the said wiring part 9 is integrally attached to the glove main body 3, it is hard to obstruct a wearer's operation | movement. Moreover, since the wiring part 9 has elasticity and deform | transforms following the deformation | transformation of the glove body 3, the wiring part 9 is hard to prevent the expansion and contraction of the glove body 3, and does not give the wearer a sense of incongruity. It is hard to get in the way of operation. Moreover, since the wiring part 9 has elasticity, it does not make it difficult to attach and detach the glove 1 with a strain sensor.

<Other embodiments>
Although the present embodiment has the above-described configuration and has the above-described advantages, the present invention is not limited to the above-described embodiment, and the design can be changed as appropriate within the intended scope of the present invention.

  In the embodiment, two strain sensors 5 are attached to the finger equivalent portion 3c of the glove body 3, and one strain sensor 5 is attached to the wrist equivalent portion 3a, that is, the glove body 3 as a whole has three strain sensors 5. Although what was attached was demonstrated, this invention is not limited to this, For example, if one distortion sensor is attached to the glove body, it is in the range which this invention intends.

  Further, the attachment location of the strain sensor 5 is not limited to that of the above embodiment. However, by attaching the strain sensor 5 to the portion corresponding to the wrist joint as in the above embodiment, it is possible to accurately grasp the movement of the wrist, and particularly to measure the movement of the hand that is important in sports or the like. . Further, as in the above-described embodiment, the strain sensor 5 is attached to a portion corresponding to a joint between adjacent phalanges of a finger (particularly, a portion corresponding to a joint between adjacent phalanges and / or a portion corresponding to a joint between adjacent phalanges of a middle finger). Thus, it is possible to accurately grasp the grasping state of the grasped object, and it is particularly suitable as a sport glove for hitting with a grasping tool such as golf or baseball.

  Furthermore, in the said embodiment, although what attached the strain sensor 5 to the outer surface of the glove main body 3 was demonstrated, this invention is not limited to this, An inner surface (wearer's hand) of a glove main body is not limited to this. In addition, when the glove body has a multilayer structure, a strain sensor can be incorporated in the glove body (intervened in an intermediate layer of the multilayer structure). Note that the strain sensor is preferably attached to a portion other than the inner surface of the glove body (for example, the outer surface of the glove body), and thus has an advantage that the wearer is less likely to feel uncomfortable.

  Moreover, although the said embodiment demonstrated what used the elastic adhesive as an attachment method of the strain sensor 5, this invention is not limited to this, Other attachment methods are employable suitably. For example, the strain sensor can be attached to the glove body by sewing so as not to impair the stretchability. Further, by attaching the strain sensor and the glove body with a hook-and-loop fastener or the like, it is possible to attach the strain sensor to the glove body so as to be detachable.

  Moreover, in the said embodiment, although the wiring part 9 was integrally provided in the glove main body 3, it demonstrated that this invention is not necessarily limited to this. Even when the wiring part 9 having stretchability is provided integrally with the glove body 3, the method of forming the wiring part 9 is not limited to the stretchable sewing. For example, as a wiring part, by knitting or weaving a conductive thread-like body together with a non-conductive thread-like body when knitting or weaving a cloth-like body constituting the glove body, this conductive filament A wiring part composed of a body can be employed. Specifically, a part of the course knitted with the conductive yarn is formed by knitting the cloth-like body by knit knitting and knitting one or more courses of the knit knitting with the conductive yarn. By this, it is possible to form a wiring part.

  In addition, the wiring portion 9 can be configured by a conductive belt-like member attached to one surface of the glove body 3. Specifically, for example, a conductive yarn can be knitted to form a stretchable and conductive string (band member), and the band member can be attached to the glove body. In addition, as this attachment method, methods such as sticking with an elastic adhesive or sewing so as not to impair stretchability can be employed.

  Further, even when the wiring portion 9 is formed by sewing conductive threads as in the embodiment, the wiring portion 9 is not limited to the one formed by stretch knitting as described above. Specifically, for example, it is also possible to sew a thread having conductivity and stretchability to the glove body by lock stitch and form a wiring portion having stretchability by using this thread.

  Further, even when the wiring portion 9 is formed by stretch knitting as in the above embodiment, the wiring portion 9 is not limited to the one formed by the cover stitch, and the wiring portion can be formed by other sewing methods. It is. Specifically, the wiring portion can be formed by sewing a thread on the glove body by chain stitching.

  In addition, in the glove 1 with a strain sensor, the wiring part 9 is not limited to adopting only one type, and it is possible to change the design as appropriate by combining a plurality of types of wiring parts described above. It is an important matter.

  In the above embodiment, a golf glove has been described as an example of the sensor-equipped glove 1. However, the present invention is not limited to this, and other sportswear may be employed, for example. Furthermore, it is also possible to employ a drive glove that is worn when driving a motorcycle or a car as the sensor-equipped glove. In this way, when the present invention is applied to a drive glove, when the drive glove recognizes a wearer's behavior abnormality (for example, a behavior abnormality due to sleep or the like), a configuration that oscillates a caution signal to an external device is configured. It can also be adopted.

  As described above, the glove with a strain sensor of the present invention is suitable for sports gloves such as a golf glove because it does not give the wearer a sense of incongruity and easily captures the movement of the wearer's hand. it can.
