Description

  The present invention relates to a fabric with a strain sensor and clothing.

  Clothing provided with a strain sensor can capture the wearer's movement as an electrical signal. As such clothes, for example, those described in JP 2011-47702 A are known. In the clothing described in this publication, a strain sensor having a carbon nanotube film oriented in a predetermined direction is attached to a base material. In the clothing described in this publication, when the carbon nanotube film is expanded and contracted along with the expansion and contraction of the base material, a detection signal is transmitted through the wiring connected to the electrode of the strain sensor. By detecting the deformation of the base material, thereby detecting the wearer's movement.

  In the clothing described in the above publication, one end of the wiring is connected to the electrode of the strain sensor, but the other part is not fixed to the substrate or the like, and this wiring is an obstacle to the wearer's operation. There is a risk. Moreover, when tension | tensile_strength arises in wiring by a wearer's body movement, there exists a possibility that wiring may be disconnected.

  In particular, in a garment provided with a large number of strain sensors, such as the glove described in the above publication, there is a significant problem that it interferes with the movement of the wearer's hand because there are many wires. Furthermore, the presence of a plurality of wires may cause the wires to get tangled and the wires to be disconnected.

JP 2011-47702 A

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a fabric with a strain sensor in which the wiring is less likely to interfere with the operation of expanding and contracting the fabric body and the wiring is less likely to break. In particular, it is an object of the present invention to provide a clothing that is unlikely to obstruct the wearer's movement and is less likely to be disconnected by the wearer's movement.

The fabric with a strain sensor according to the present invention, which has been made to solve the above problems,
A fabric with a strain sensor, comprising a fabric body that can be stretched and a strain sensor attached to the fabric body and capable of following the stretch of the fabric body,
A wiring portion is provided which is electrically connected to the strain sensor and is provided integrally with the fabric body and deforms following the expansion and contraction of the fabric body.

  When the strain sensor is expanded and contracted as the fabric body expands and contracts, a detection signal is transmitted to the fabric with the strain sensor via a wiring portion electrically connected to the strain sensor. It can be measured. Since the wiring portion is provided integrally with the fabric body, the wiring portion is unlikely to interfere with the operation of expanding and contracting the fabric body. Moreover, since the said wiring part deform | transforms following the expansion / contraction of a fabric main body, it does not prevent expansion / contraction of a fabric main body, but follows the operation | movement which expands / contracts the above-mentioned fabric main body, and a fabric main body tends to expand / contract. Furthermore, since the wiring portion is integrally provided on the fabric body and is deformed following the expansion and contraction of the fabric body, the wiring portion itself is not easily disconnected.

  The fabric with the strain sensor can employ a configuration in which the wiring portion is formed by sewing a conductive filamentous body to the fabric body. Thereby, a wiring part can be easily and reliably formed by sewing a threadlike body easily.

  The fabric with a strain sensor is made of a fabric formed by knitting or weaving a thread-like body having no electrical conductivity, and the wiring portion is electrically conductive when the fabric body is knitted or woven. It is possible to adopt a configuration formed by knitting or weaving a conductive filamentous body together with a filamentous body that does not have a thread. As a result, the wiring portion can be easily and reliably formed by using the conductive filamentous body together with the non-conductive filamentous body constituting the fabric body when the fabric body is knitted or woven.

  The fabric with the strain sensor can employ a configuration formed of a band-like member attached to one surface of the fabric body. Thereby, a wiring part can be formed easily and reliably by attaching a strip | belt-shaped member to a fabric main body.

  The clothing according to the present invention includes the fabric with the strain sensor having the above-described configuration. Accordingly, when the strain sensor is expanded and contracted by the operation of the wearer of the clothing, a detection signal is transmitted through the wiring portion electrically connected to the strain sensor, and the operation of the wearer is detected by the detection signal. I can. In the clothing, since the wiring portion deforms following the expansion and contraction of the fabric body, the wiring portion does not hinder the expansion and contraction of the fabric body and is unlikely to obstruct the wearer's operation. Furthermore, since the wiring portion is integrally attached to the fabric body and is deformable as described above, the wiring portion itself is not easily disconnected.

  As described above, in the fabric with a strain sensor of the present invention, the wiring is less likely to interfere with the operation of expanding and contracting the fabric body, and the wiring is less likely to break. Moreover, the clothes which concern on this invention do not become easy to obstruct a wearer's operation | movement, and are hard to produce the disconnection by a wearer's operation | movement.

It is the schematic explanatory drawing explaining the wiring part of the clothes of FIG. 1, (a) is the schematic explanatory drawing seen from the outer surface of the fabric, (b) is the schematic explanatory drawing seen from the inner surface of the fabric. .

  Hereinafter, embodiments of the present invention will be described. First, as an embodiment, compression wear worn on the lower body will be described as an example with reference to FIGS. 1 and 2.

<Clothing 1>
The clothing 1 in FIG. 1 includes a fabric 10 with a strain sensor and a transmission module 20 that transmits a detection signal detected by the strain sensor 13.

(Fabric with strain sensor 10)
The fabric with strain sensor 10 includes a stretchable fabric body 11, a strain sensor 13 attached to the fabric body 11, and a pair of wiring portions for electrically connecting the strain sensor 13 and the transmission module 20. 12 is provided.

  The fabric body 11 is knitted or woven with yarns (filamentous bodies). As the yarn constituting the fabric body 11, one having stretchability is preferably used, and it is preferable that the fabric body 11 is provided so as to be stretchable as a whole by knitting the yarn. Moreover, the thread | yarn which comprises this fabric main body 11 does not have electroconductivity suitably.

  The strain sensor 13 is integrally attached to the fabric body 11. The strain sensor 13 is disposed, for example, in a part of the clothing 1 where the movement of the wearer can be recognized, for example, a part corresponding to a joint, and is disposed on the front side of the knee joint in the illustrated example.

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

  Moreover, it is preferable that the strain sensor 13 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 expansion and contraction of the fabric body 11 may be hindered by the layer in which the elastic adhesive is cured. On the other hand, if the elastic modulus is less than the lower limit, the expansion / contraction of the fabric body 11 is absorbed by the layer made of the elastic adhesive, and may not be accurately transmitted to the strain sensor 13.

  The strain sensor 13 is attached to the fabric body 11 so as to follow the expansion and contraction of the fabric body 11. Specifically, the strain sensor 13 has stretchability and is attached to the fabric body 11 having stretchability so that the strain sensor 13 is stretched as the fabric body 11 stretches. Yes. It is also possible to provide the strain sensor 13 so that the strain sensor 13 expands and contracts according to the expansion and contraction of the fabric body 11 by fixing the strain sensor 13 to the fabric body at least at both ends (for example, pasting, sewing, etc.). The strain sensor 13 transmits an electrical signal (detection signal) to the wiring unit 12 according to expansion and contraction. As the strain sensor 13, a CNT strain sensor 13 using a carbon nanotube (hereinafter sometimes referred to as CNT) is preferably used. The CNT strain sensor 13 includes a substrate attached to the fabric body 11, a CNT film provided on the surface side of the substrate, a pair of electrodes respectively disposed at the ends of the CNT fibers, and the CNT And a protective part for protecting the film.

  The substrate of the CNT strain sensor 13 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). When the strain is applied in the direction in which the pair of electrodes are separated due to the orientation of the CNT fibers in this manner (when the CNT film is stretched), the contact condition between the CNT fibers changes, and the strain sensor 13 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 part and the CNT fiber are electrically connected, and the case where the parts other than the connection part of the CNT fiber are electrically connected is also included in the connection. The contact between the CNT fibers means that the CNT fibers are in contact with the above-mentioned connecting portions but are not electrically connected, and the non-connected portions of the CNT fibers are in contact with each other but are not electrically connected. 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 B (longitudinal direction of the CNT film). Accordingly, the rigidity of the CNT film becomes stronger in the direction perpendicular to the orientation direction of the CNT fiber (longitudinal direction of the CNT film), and the CNT strain sensor detects sensitively to the strain in the longitudinal direction of the CNT film. And 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 is further reduced, and a strain sensor having strong 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 a strain sensor can be enhanced.

  In the connection part, the CNT single fibers are bonded together by 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. When the average thickness of the CNT film is less than the above lower limit, it may be difficult to form such a thin film, or the resistance may increase excessively. On the other hand, when the average thickness of the CNT film exceeds the above upper limit, the stretchability may be lowered and the sensitivity to the stretch may be lowered.

  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.

  The wiring portion 12 is composed of a conductive thread (thread-like body) sewn on the fabric body 11, and the wiring portion 12 is integrated with the fabric body 11 by being sewn on the fabric body 11 in this manner. Provided.

  As the yarn constituting the wiring portion 12, 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, there is an advantage that the electric resistance is small and the change in the electric resistance is relatively small even when the clothes 1 are washed. In addition, as a thread | yarn which comprises this wiring part 12, it is also possible to use the thread | yarn which apply | coated the conductive material to the insulating thread | yarn, and the thread | yarn formed by mixing a conductive material.

  The yarn constituting the wiring portion 12 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 12 can be reduced, and the detection signal from the strain sensor 13 can be accurately transmitted to the transmission module 20. 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 12 has elasticity and is provided so as to deform following the expansion and contraction of the fabric body 11. Specifically, the wiring part 12 is formed by elastically 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 12 of this embodiment is formed by cover stitch (single-sided decorative stitching) as shown in FIG.

(Transmission module 20)
The transmission module 20 is disposed at a location that does not interfere with the wearer, for example, at the skirt. In addition, in the case of the clothing 1 having a pocket, the formation place is not particularly limited, such as the transmission module 20 being disposed in the pocket. Moreover, although it is possible to fix the transmission module 20 to the fabric body 11, it is preferable that the transmission module 20 is detachably attached to the fabric 10 with a strain sensor. In addition, although the means to attach this detachably is not specifically limited, For example, a hook-and-loop fastener etc. are employable. By providing the transmission module 20 detachably on the fabric body 11 as described above, the fabric body 11 of the clothing 1 can be easily and reliably washed with the transmission module 20 removed.

  The transmission module 20 includes a transmission unit that can transmit the detection signal received via the wiring unit 12 to an external device by wireless communication. In the clothing 1, the transmission module 20 includes a storage unit that accumulates the detection signal received via the wiring unit 12, and the transmission module 20 includes a processing unit that determines the detection signal. It is also possible to adopt.

A step of attaching the strain sensor 13 to the fabric body 11 after the sewing step, and a step of attaching the transmission module 20. Before and after the wiring portion forming step and the strain sensor attaching step are not particularly limited. The wiring portion 12 can be formed first and the strain sensor 13 can be attached later. Alternatively, the strain sensor 13 can be attached first and the wiring portion 12 can be attached. It is possible to change the design as appropriate, and to sew the strain sensor 13 when the wiring portion 12 is formed. Moreover, it is also possible to perform the sewing process which sews the fabric main body 11 after performing the wiring part 12 formation process and / or the distortion sensor 13 attachment process.

<Advantages>
In the clothes 1 having the above-described configuration, when the strain sensor 13 is expanded and contracted by the wearer's movement, the strain sensor 13 transmits a detection signal to the transmission module 20 via the wiring portion 12 and receives the detection signal. The transmission module 20 transmits a detection signal to the external device. For this reason, a wearer's operation | movement can be detected by discriminating a detection signal in an external device.
