Referring to FIG. 1, the motion recognition fabric sensor 100 may comprise a fabric base layer 10, a conductive material layer 20, and a metallization layer 30.

The body part of the human body operates in a non-uniform manner. Therefore, when the motion recognition fabric sensor is positioned in the operation area, only a part of the motion recognition fabric sensor is oversupplied. Since the measurement signal during operation sensing includes noise, due to the extension of the non-uniform motion recognition fabric sensor, not only the structure that reduces the transfer of the non-uniform shape change of the body region to the motion recognition fabric sensor, It is necessary to use a composition composed of materials capable of reducing generated noise. Therefore, the present invention will describe a motion recognition fabric sensor comprising a composition made of materials capable of reducing motion artifacts and a method of manufacturing the same.

The fabric base layer 10 may comprise natural fabrics such as cotton, hemp, and dog, synthetic fibers such as nylon, polyester, acrylic, polyurethane, PVC, PCB, and PP, or combinations thereof. However, the type of the fabric constituting the fabric base layer 10 is not limited thereto, and may include all the fabrics used in all natural fiber fabrics and all synthetic fiber fabrics.

In one embodiment, the fabric base layer 10 may be a separate layer from the fabric layer making up the garment, or it may be the same layer as the fabric layer making up the garment. For example, if the operational motion recognition fabric sensor according to an embodiment of the present invention is fabricated separately from the garment, the fabric base layer 10 may be a fabric layer separate from the fabric layer making up the garment. However, if the motion-aware fabric sensor is fabricated in a single process at the time of garment manufacturing, a fabric layer that constitutes the garment may be fabricated as the base layer 10 to produce a motion-aware fabric sensor.

The conductive material layer 20 may be formed on at least one of the surface of the fabric base layer 10 and the inside of the fabric base layer 10 and the resistance of the conductive material in the conductive material layer 20 may change due to the operation, Size, and direction of the image.

The conductive material layer 20 may be formed on the surface of the fabric base layer 10 as well as formed within the fabric base layer 10 by penetrating between the pores of the fabric base layer 10. Due to the conductive material layer 20 formed in and on the fabric base layer 10, the motion recognition fabric sensor may have overall conductivity. When the conductive material layer 20 is suitably coated on and in the fabric base layer 10, it can have high electrical conductivity and linearity characteristics.

The carbon nanoparticles may be dispersed within the polymer compound.

In order to uniformly disperse the carbon nanoparticles in the polymer compound or increase the measurement function, sensitivity, etc., the surface of the carbon nanoparticles can be modified by acid treatment. When the carbon nanoparticles are subjected to an acid treatment, the carbon nanoparticles may have a functional group such as carboxylic acid. In addition, the carbon nanoparticles may be doped with impurities or further coated with a necessary material.

The polymer may be polymethyl methacrylate, but it is not limited thereto, and materials capable of exhibiting properties required as a measuring device by uniformly dispersing the carbon nanoparticles can be applied. That is, examples of the polymer include polyether sulfone, epoxy, polyvinylidine fluoride, polyethylene, polyvinyl chloride, polypropylene, But are not limited to, polyesters, acrylic, nylon, cellusosic, acrylonitrile-butadiene-styrene polymer, polycarbonate, Acetal, Fluoroplastic and the like. At least two or more of them may be used together. In addition, fiber-reinforced plastic (FRP) may be used as the polymer.

In one embodiment, the conductive material layer 20 may be laminated with two or more conductive material layers sandwiched between intermediate fabric layers (not shown). The intermediate fabric layer may be made of cotton, hemp, silk, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP, or a combination thereof. However, the kind of the fabric constituting the intermediate fabric layer is not limited to this, and may include any fabric used for the fabric of all the natural fibers and the fabric of all the synthetic fibers.

In one embodiment, the intermediate fabric layers may all be composed of the same fabric, but may also be composed of fabrics that are different from one another according to the purpose of the motion recognition fabric sensor. In addition, the intermediate fabric layer may be composed of the same fabric as the fabric base layer 10, or it may be composed of a different fabric. Further, each conductive material layer and the intermediate fabric layer may have the same thickness and different thicknesses depending on the purpose of the motion recognition fabric sensor.

Further, in one embodiment, a plurality of conductive material layers and an intermediate fabric layer are laminated on the fabric base layer 10, and a layer of conductive material formed on the fabric base layer 10 and intermediate fabric layers A binder layer (not shown) may be further included. The binder layer may be coated on at least one surface of the intermediate fabric layer and may be provided in an integrated state or may be provided as a separate paste layer. In addition, unlike conventional binders, the binder layer has both adhesive properties and conductivity, which serves as a conductive material, in order to maintain the electrical properties of the conductive material layer. Thus, the binder layer has two functions, It can serve as a layer.

In one embodiment, a metal wiring layer 30 may be formed on the conductive material layer 20. The metal wiring layer 30 includes a signal transmission interconnection for transmitting a signal measured in the conductive material layer 20 and a current / voltage / power supply interconnection for supplying a current / voltage / electric power to the conductive material layer 20 Connection, and the like.

The metal wiring layer 30 may be electrically connected to the conductive material layer 20. The metal wiring layer 30 may be formed by electrically connecting one end of the conductive material layer 20 to one end of the conductive material layer 20 by means of the electrically conductive bonding means or by printing on the fabric base layer 10 from one end of the conductive material layer 20 have. When the metal wiring layer 30 is printed and formed on the fabric base layer 10, the electrically conductive bonding means disposed at one end of the conductive material layer 20 may be omitted. When the metal wiring layer 30 is electrically connected to the conductive material layer 20 by the electrically conductive bonding means, the electrically conductive bonding means may use a conductive snap button or a conductive silver epoxy paste, Materials and components capable of electrically connecting the conductive material layer 20 to the conductive interconnection may be selectively applied.

The metal wiring layer 30 can be grown from the conductive material layer 20 with a width of 3 to 50 mm. In the case where the metal wiring layer 30 has a width of less than 3 mm and the deformation such as folding, stretching, or wrinkling occurs due to the operation of the operation recognition fabric sensor, the printed metal wiring layer 30 It is likely to fall or short circuit. It goes without saying that the operation can not be sensed when the metal wiring layer 30 is dropped or short-circuited. In addition, when the metal wiring layer 30 has a width of more than 50 mm, noise may occur due to physical proximity to the conductive material layer 20, and as in the case where the metal wiring has a width of less than 3 mm, The possibility of falling or short-circuiting when the clothes are deformed by the wiring can be increased.

As described above, the motion recognition fabric sensor of the present invention can be fabricated by printing and using the metal wiring layer 30 without using a wire as a wiring structure, so that flexibility and flexibility that are not dropped or short-circuited even when deformation such as friction, wrinkling, But also can be non-binding and comfortable. The motion recognition fabric sensor of the present invention having these characteristics may be effective in application to garments for measuring and analyzing the wearer's actions. In addition, although the conventional metal wiring layer 30 is formed by performing an etching or plating process, since the metal wiring layer 30 of the present invention does not use this method, it is possible to provide an effect of preventing environmental pollution .

In one embodiment, an insulating layer (not shown) may be formed on the conductive material layer 20 to cover the conductive material layer 20. If the conductive interconnection is formed around the conductive material layer 20, the insulating layer may be formed to cover a portion of the conductive material layer 20 and the conductive interconnection. The insulating layer may be made of cotton, hemp, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP, or a combination thereof. However, the kind of the fabric constituting the insulating layer is not limited thereto, and may include any fabric used for all natural fiber fabrics and all synthetic fiber fabrics, but it may be a fabric having insulating properties, May be a coated fabric. In one embodiment, the insulating layer may be composed of a fabric having insulation and waterproof function. Further, the fabric base layer 10) and the insulating layer may be composed of the same fabric or may be made of different fabrics.

In one embodiment, the insulating layer (not shown) may be a fabric layer comprised of polyurethane.

2 is a flow chart illustrating a method of fabricating a motion recognition fabric sensor in accordance with an embodiment of the present invention.

Referring to FIG. 2, first, a conductive slurry can be formed by mixing carbon particles, a solvent, and a polymer compound (S10). The conductive slurry may be in the form of a conductive liquid having a low fluidity, and may include the carbon particles and the polymer compound. In one embodiment, the conductive slurry is prepared by mixing 20 to 40% by weight of carbon nanoparticles having a specific surface area of 50 to 300 m ² / g, 40 to 60% by weight of a hydrophilic solvent, and 5 to 20% And stirred for 45 minutes (S10). In the stirring step, the carbon nanoparticles, the hydrophilic solvent, and the polymer compound may be simultaneously mixed and stirred, or may be gradually mixed and agitated through two or more steps. In one embodiment, the stirring step is performed by first dispersing the carbon nanoparticles in the hydrophilic solvent for 1 to 10 times for 30 to 90 seconds, and adding the polymer compound to the slurry formed in the first dispersion step, 10 times.

Thereafter, a fabric base layer is placed in the conductive slurry and placed in a desiccator in a vacuum state so that the conductive slurry can be sufficiently deposited on the fabric base layer (S20). The fabric base layer thus deposited with the conductive slurry may be coated by coating the conductive slurry through the pores of the fabric base layer and penetrating the inside of the fabric base layer and coating the surface of the fabric base layer.

The fabric base layer on which the conductive slurry is deposited is between 80 and 160? Lt; RTI ID = 0.0 > (S30). ≪ / RTI > Through such a process, a fabric base layer and a conductive material layer according to an embodiment of the present invention can be formed. In addition, the carbon nanoparticles included in the conductive material layer may be formed in contact with each other in the conductive material layer to form a conductive path. The dried and cured conductive material layer can be prevented from being oxidized to a sharp increase in electrical resistance even when the conductive material layer is exposed to the air for a long period of time and thus the carbon nanoparticles in the conductive material layer are oxidized.

Figures 3 and 4 may be images representing a motion recognition fabric sensor in accordance with an embodiment of the present invention.

3, the elastic fabric membrane 100 including the fabric base layer 10 and the conductive material layer 20 described with reference to FIGS. 1 and 2 further includes a coupling member 200 at both ends thereof . In one embodiment, the stretch fabric membrane 100 may include longitudinally divided end portions A and a central portion B. In one embodiment, The joining member 200 may be formed on both ends A of the stretch fabric membrane 100. The engaging member 200 may be a member that can be engaged with a garment such as a snare, but is not limited thereto, as long as the member is capable of engaging the elastic fabric membrane 100 to the garment. In one embodiment, the fabric base layer 10 of the stretch fabric membrane 100 is part of the same layer as the fabric of the garment, i. E., The fabric forming the garment in the garment manufacturing process is the fabric base layer 10 or the cover layer The joining member may be omitted when the motion recognition fabric sensor is manufactured.

Referring to FIG. 4, the flexible membrane 100 may include a metal wiring layer 30 connected to one end of the end portion A. The metallization layer 30 may be formed in a printing manner on the garment to which the motion recognition fabric sensor is coupled. The metal wiring layer 30 may be formed of a metal such as carbon or aluminum, silver, copper, or stainless steel. In one embodiment, the metallization layer 30 may be printed on a portion of the stretch fabric membrane at a width of 3 to 50 mm or a garment to which the stretch fabric membrane is bonded. Also, in other embodiments, the metal wiring layer 30 may be connected to the central portion B of the elastic membrane 100, and the contact portion is not limited to the above embodiment if it is in contact with a portion of the elastic membrane 100.

In one embodiment, the central portion B of the elastic fabric membrane 100 has a rectangular shape. Referring to the connection region C where the both ends A and the central portion B are connected to each other, B may be formed to be smaller than the width of the both end portions A. [ That is, the width b of the central portion B of the elastic fabric membrane 100 may be smaller than the diameter a of the engaging member 200. However, the shape of the stretch fabric membrane is not limited to the present invention. Thus, by minimizing the cross-sectional area of the elastic fabric membrane 100 coupled with the coupling member 200, it is possible to reduce the dynamic noise due to the pressure applied to the elastic fabric membrane 100 by the coupling member 200.

As described above, the motion recognition fabric sensor of the present invention is formed by adopting the printing method instead of the conventional metal yarn joining method as the metal wiring layer 30, so that the motion recognition fabric sensor is free of constraint and high comfort, And it is easy to apply to clothes because it has flexibility that it does not fall short. In addition, since no metal yarn or wire is used, an etching or plating process is not required and environmental pollution can be reduced.

In addition, the motion recognition fabric sensor 100 in accordance with various embodiments of the present invention is a motion recognition fabric sensor fabricated using printing techniques with conductive materials coated and metallized layer 30, which is integrated with the garment, (User) attached to the body of the wearer so as to be able to accurately measure the motion information of the body such as the position, angle, and speed of the motion area at the time of operation.

Figures 5 and 6 illustrate a portion of an apparel system that includes an action recognition fabric sensor for measuring a user ' s action in accordance with an embodiment of the present invention.

1 to 4, a garment system incorporating motion recognition fabric sensor 100 includes a fabric base layer 10, a layer of conductive material 20, a metallization layer 30, and a coupling member 200 . The fabric base layer 10 may comprise cotton, hemp, dog, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP or combinations thereof. If the motion recognition fabric sensor 100 is fabricated in one piece with the garment, the fabric base layer 10 may be the fabric that makes up the garment. The fabric base layer 10 may have the same configuration, materials, and functionality as the fabric base layer 10 described above with reference to Figs. 1-4. The conductive material layer 20 may also be coated on the inside and on the surface of the fabric base layer 10 and coated on the location and size of the area where the fabric base layer 10 needs to be actuated.

Further, the motion recognition fabric sensor 100 of the garment system according to an embodiment of the present invention may be disposed at a position spaced from the area where the user's operation occurs on the garment system. When the motion recognition fabric sensor 100 is coupled to the garment such that the center of the motion recognition fabric sensor 100 corresponds to the center of the joint where the motion is generated, 100 can be extended with only a portion of the motion recognition fabric sensor 100 such that the central portion of the motion recognition fabric sensor 100 is stretched excessively and the outer portion is less stretched.

In this case, a large amount of noise is generated in the operation signal measured by the motion recognition fabric sensor 100. Therefore, there is a need to incorporate the motion recognition fabric sensor 100 at a location spaced from the area where the motion occurs.

In addition, the body surface of the joint region is extended most in the human body during the operation of the wearer of the motion recognition fabric sensor 100, but the position spaced from the joint region can be extended most in the clothes. Therefore, by disposing the motion recognizing fabric sensor 100 at a position spaced a certain distance from the area where the operation occurs, it is possible to measure an accurate signal with reduced noise generated during operation.

For example, when an attempt is made to measure the motion of an arm or leg, the motion recognition fabric sensor 100 is positioned at a distance of 3 cm to 15 cm from the center of the arm or leg joint, It is preferable to be coupled to the garment so that the end is located. When the position of the motion recognition fabric sensor 100 is coupled to the garment area at a distance of less than 3 cm from the center of the joint, there is a large influence from the movement of the joint, and noise or double peak . In addition, when the position of the motion recognition fabric sensor 100 is coupled to the garment area at a position spaced 15 cm from the center of the joint, the degree of stretching of the garment and motion recognition fabric sensor 100 by operation The operation can not be accurately measured.

Further, for example, when it is desired to measure the motion of the hip joint, the motion recognition fabric sensor 100 may be provided with a first motion recognition fabric sensor for measuring the motion in the vertical direction in the gravity direction, And a second motion recognition fabric sensor for measuring the motion of the first motion recognition fabric. In one embodiment, the first motion recognition fabric sensor is coupled onto the waistline of the garment, and the second motion recognition fabric sensor is coupled to the garment area at a location within 2 to 20 cm left and right from the rear centerline of the garment Thereby contributing to improvement of the quality of the operation signal.

In the case of a garment system in which the motion recognition fabric sensor 100 is combined, the motion recognition fabric sensor 100 is combined in the garment system with no deformation of the position in the region where the noise can be measured, It is important to measure motion. The garment system may further include one or both of the spaced-apart position retaining portion 300 and the coherent band structure 400 to prevent deviation of the motion recognition fabric sensor 100 from the engaged position.

5, the spacing position retainer 300 may be coupled to at least one end of the motion recognition fabric sensor 100 and may be configured to move the motion recognition fabric sensor 100 from a region where the user's motion occurs And can be connected to maintain its position. The spacing position retaining portion 300 is made of a non-stretchable material so that the position of the motion recognition fabric sensor 100 can be fixed even during operation of the user. In one embodiment, the spacing position retainer 300 may include a rectangular tape structure, a spiral cord structure, and a twist structure comprised of a plurality of cords.

Referring to FIG. 6, the garment system may further include a close band structure 400 to prevent positional deformation of the motion recognition fabric sensor 100. The close band structure 400 may be connected to one end of the motion recognition fabric sensor 100 or to one end of the garment system. For example, when the motion recognition fabric sensor 100 is disposed at the lower end of the elbow, the intimate band structure 400 may be formed at the cuff or shoulder joint region of the garment system. In this case, since the motion recognition fabric sensor 100 is increased in extension by the close-contact band structure 400, the size of the operation signal is increased and the motion recognition fabric sensor 100 is moved from a position It is possible to reduce the noise or the double peak signal generated in the operation signal measurement.

FIGS. 7A and 8B illustrate results of measurement of an operation signal according to a position where the motion recognition fabric sensor is attached to the garment according to an exemplary embodiment of the present invention. Figure 7a is a signal measured from a garment system coupled to a position spaced from an elbow where the motion recognition fabric sensor as shown in Figure 4 occurs where the motion occurs and Figure 7b shows a signal corresponding to the elbow, Lt; RTI ID = 0.0 > position < / RTI >
