Description

TECHNICAL FIELD [0001] The present invention relates to a motion sensing cloth sensor and a garment system including the motion sensing cloth sensor.

Field of the Invention [0002] The present invention relates to an operation sensor, and more particularly, to an operation recognition fabric sensor for measuring an operation of a user's body part.

There are a lot of studies that allow users to measure their physical condition through clothing, and related products are also being actively traded in the market. However, when the shape of the sensor is deformed or the position is moved due to the user's movement, the position of the human body sensor is changed and the accuracy of the body state measurement is degraded. This is a problem in the detection of the physical condition in which the user must perform continuous measurement while wearing in daily life.

For example, in the case of contact detection, the contact point between the human body surface and the sensor moves in the X and Y axes due to human motion, which causes motion artifacts, . Also, even in the case of the non-contact sensing method, if the distances in the X, Y and Z directions between the human body and the sensor to be sensed are changed, the quality of the signal is degraded. Furthermore, due to the movement of the garment due to the movement of the wearer, the measurement accuracy of the body condition such as heartbeat, motion, breathing, blood pressure, and motion is degraded when the position of the wearer's body or clothing changes. In addition, since the garment for detecting the physical condition is not restored to its original position after the human body operation, there is a difficulty in accurate detection due to the movement of the sensor.

SUMMARY OF THE INVENTION The present invention provides an operation recognition fabric sensor that accurately detects movement of a human body by minimizing a movement of a sensor during a human body operation.

In one embodiment, when the area in which the user's action occurs is a hip joint, the motion recognition fabric sensor may be disposed at a waist region of the user spaced apart from the hip joint and at a periphery of the waist region.

The motion recognition fabric sensor may have a length of 0.1 to 8 cm.

According to the present invention, by minimizing the three-dimensional (X-axis, Y-axis, Z-axis) movement of the motion recognition fabric sensor coupled to the garment system in spite of the motion of the human body, .

According to the present invention, in order to reduce noise due to inhomogeneous elongation of a sensor caused by a change in shape of an operating site skeleton during a human body operation, an operation recognition fabric sensor is installed in a clothing system By combining, the measurement accuracy of the motion recognition fabric sensor can be improved.

The U-health care market is expected to grow steadily, as the demand for healthcare is rapidly increasing, as the demand for healthcare is expanding from the elderly to the younger, due to aging, low fertility, increased chronic diseases, and increased income. In this case, in order to realize the accurate operation of the sensor in the smart clothing which can measure the bio-signals, the following clothing design is considered to minimize the movement of the sensor attached to the clothes and minimize the noise generated when sensing the bio- .

1 is a structural view illustrating a structure of a motion recognition fabric sensor according to an embodiment of the present invention. Referring to Figure 1, a motion sensing fabric sensor 1000 includes a padding layer 100, a lower fabric layer 200, a conductive material layer 300, a conductive interconnection 400, and an insulating upper fabric layer 500 .

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. Because of the non-uniform movement of the motion recognition fabric sensor, the measurement signal at the time of motion sensing includes noise, and thus a structure is required to reduce the transmission of non-uniform shape changes of the human body to the motion recognition fabric sensor.

The padding layer 100 is formed at the bottom of the fabric layer and the conductive material layer that serves as a sensing for the motion recognition fabric sensor 1000 and includes a cushioning material for reducing the transfer of non- The noise generated during operation can be reduced. The padding layer 100 may be positioned between the lower fabric layer 200 and the garment to reduce noise from positional displacement resulting from movement of the garment when the motion recognition fabric sensor 1000 is coupled to the garment.

The padding layer 100 may be comprised of a fabric and may comprise, for example, cotton, hemp, dog, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP or combinations thereof. In addition, the padding layer 100 is formed of a fabric and may include an air layer therein. In addition, the padding layer 100 may use a gel pad having elasticity.

The padding layer 100 may be formed at a location spaced apart from the area where the operation is to occur. Of course, since the padding layer 100 is formed at a position spaced apart from the area in which the action is generated, the entire motion recognition fabric sensor 1000 can be formed at a position spaced apart from the area where the action occurs. The padding layer 100 is formed at a position spaced apart from joints where an action such as an elbow and a knee is generated, so that the entire motion recognition fabric sensor 1000 can be formed at a position spaced apart from the area where the motion occurs. For example, the motion recognition fabric sensor 1000 including the padding layer 100 may be bonded to the garment at a location 3 cm to 20 cm away from the elbow toward the shoulder or toward the cuff.

In one embodiment, the padding layer 100 may be omitted. When the padding layer 100 is omitted, the motion recognizing fabric sensor 1000 is formed at a position spaced apart from the articulation portion, and can recognize the operation at a position apart from the region where the operation occurs. The operation recognition fabric sensor 1000 according to an embodiment of the present invention may be attached to a joint site where an operation occurs and measure an operation by being coupled to a position spaced apart from a region where the operation occurs rather than measuring the operation of the human body More effective will be described later with reference to Figs. 4 and 5.

The lower fabric layer 200 may be formed on the padding portion 100 and may be greater than or equal to the area of the padding portion 100. The lower fabric layer 200 may be made of cotton, hemp, silk, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP, or combinations thereof. However, the type of the fabric constituting the lower fabric layer 200 is not limited to this, and may include any cloth used for clothing, such as all natural fiber fabrics and all synthetic fiber fabrics.

In one embodiment, the lower fabric layer 200 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 motion sensing recognition fabric sensor according to one embodiment of the present invention is fabricated separately from the garment, the lower fabric layer 200 may be a fabric layer separate from the fabric layer making up the garment. However, when the operation-aware fabric sensor is manufactured in a single process at the time of manufacturing clothes, the operation-aware fabric sensor may be fabricated using the fabric layer constituting the garment as the lower fabric layer 200.

Conductive material layer 300 may be coated with a material having conductivity on the lower fabric layer 200. The conductive material layer 300 may be formed of any one or any of metal such as carbon nanotube (CNT), carbon fiber, carbon metal, conductive polymer, graphene, aluminum, silver, copper, Or more of the conductive nanoparticles, and preferably, the carbon nanotubes. When the conductive material layer 300 is appropriately coated on the lower fabric layer 200, it has high electrical conductivity and linearity characteristics.

In one embodiment, the conductive material layer 300 may further comprise a polymer. In this case, the conductive nanoparticles may be a plate-shaped film member made of a nanocomposite material oriented in one direction or in various directions within the polymer. The conductive nanoparticles may be dispersed within the polymer.

In order to uniformly disperse the conductive nanoparticles in the polymer, or to increase the measuring function, sensitivity, etc., the conductive nanoparticles may be subjected to an acid treatment to modify the surface. When the conductive nanoparticles are subjected to an acid treatment, the conductive nanoparticles may have functional groups such as carboxylic acid. In addition, the conductive nanoparticles may be doped with impurities or further coated with necessary materials.

The polymer may be polymethyl methacrylate, but is not limited thereto. The conductive nanoparticles may be uniformly dispersed to provide a material capable of exhibiting properties required for a measurement device. 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.

Conductive interconnection 400 may be formed on conductive material layer 300. The conductive interconnection 400 includes at least one of a signal transfer interconnection for transferring the signal measured in the conductive material layer 300 and a power supply interconnection for supplying power to the conductive material layer 300 .

The conductive interconnection 400 may be electrically connected to the conductive material layer 300. The conductive interconnection 400 may be electrically connected to one end of the conductive material layer 300 by one or more electrically conductive adhesive means. The electrically conductive adhesive means may include, but is not limited to, a conductive snap button or a conductive silver epoxy paste, and may include materials and components capable of electrically connecting the conductive material layer 300 to the conductive interconnection 400, .

The insulating top fabric layer 500 may be formed to cover a portion of the conductive material layer 300 and the conductive interconnection 400. The insulating top fabric layer 500 may be made of cotton, hemp, silk, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP, or combinations thereof. However, the type of the fabric constituting the insulating upper fabric layer 500 is not limited to this, and may include any fabric used for clothes such as all natural fiber fabrics and all synthetic fiber fabrics. However, Or may be a fabric coated with an insulating material. Further, the insulating upper fabric layer 500 may be composed of a fabric having insulation and waterproof function.

In one embodiment, the insulating top fabric layer 500 may be a fabric layer comprised of polyurethane. The insulating upper fabric layer 500 can prevent the performance of the sensor from degrading by energizing the conductive material layer 300 and the conductive interconnection 400 when the motion recognition fabric sensor is in contact with sweat or water.

2 is a cross-sectional view of a layer of conductive material 300 in accordance with an embodiment of the present invention. Referring to FIG. 2, the conductive material layer 300 may include a conductive nanoparticle layer 310, 330, 350 and an intermediate fabric layer 320, 340.

The conductive material layer 300 may be formed as a layered structure of the conductive nanoparticle layers 310, 330, and 350 and the intermediate fabric layers 320 and 340. The conductive nanoparticle layers 310, 330 and 350 may be formed of any one of carbon nanotube (CNT), carbon fiber, carbon metal, graphene, conductive polymer and aluminum, silver, copper, Or mixtures of any one or more thereof. The conductive nanoparticle layers 310, 330, and 350 may all comprise the same material, but may include materials that are different from one another for purposes of the motion recognition fabric sensor.

The intermediate fabric layer 320 may be made of cotton, hemp, silk, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP, or combinations thereof. However, the type of the fabric constituting the intermediate fabric layer 320 is not limited thereto, and may include all the fabrics used in the garment such as all natural fiber fabrics and all synthetic fiber fabrics.

In one embodiment, the intermediate fabric layer 320 may all be composed of the same fabric, but may also be constructed of fabrics that are different from one another according to the purpose of the motion recognition fabric sensor. In addition, the intermediate fabric layer 320 may be composed of the same fabric as the lower fabric layer 200, or may be composed of a different fabric. In addition, each of the conductive nanoparticle layers 310,330, 350 and the intermediate fabric layers 320,340 may have the same thickness and may have different thicknesses depending on the purpose of the motion recognition fabric sensor. Various embodiments related to this will be described later with reference to Figs. 3A to 3C.

3A-3C are cross-sectional views of an operational recognition fabric sensor 1000 including a lower fabric layer 200 and a conductive material layer 300 in accordance with an embodiment of the present invention. Figure 3a shows the case where the conductive material layer 300 formed on the lower fabric layer 200 is composed of a single layer and Figure 3b shows that the conductive material layer 300 comprises a plurality of conductive nanoparticle layers and a middle fabric layer And FIG. 3C shows a case where a conductive material layer 300 is formed on the upper and lower portions of the lower fabric layer 200.

Referring to FIG. 3A, a layer of conductive material 300 may be coated or printed on the lower fabric layer 200 to constitute an element of one motion recognition aware fabric sensor 1000. The conductive material layer 300 may be formed on the lower fabric layer 200 by a method such as spin coating, spray coating, printing, vacuum filtration, impregnation coating, coating, or printing.

3B, a plurality of conductive nanoparticle layers and an intermediate fabric layer are laminated on a lower fabric layer 200 and a conductive nanoparticle layer 310 and 330 formed on the lower fabric layer 200 and an intermediate fabric layer 320 may further include a binder layer 315 to improve adhesion.

The binder layer 315 may be coated on one surface of the intermediate fabric layer 320 and may be provided in an integrated state or may be provided as a separate paste layer. Unlike a conventional binder, the binder layer 315 has adhesiveness and conductivity, which serve as a conductive material, to maintain the electrical characteristics of the conductive nanoparticle layers 310 and 330. Therefore, It should serve as an integral binder layer having branch functions. Therefore, the binder layer 315 may be formed of a conductive material such as polyperfluorosulfonic acid, poly [2,2 '- (m-phenylene) -5,5'-bibenzimidazole, poly [ Diazoles], polybenzoxazole or polybenzothiazole. In one embodiment, when the thickness of the binder layer 315 is 0.1 mm to 5 mm, which is relatively thinner than the conductive nanoparticle layers 310 and 330, the conventional insulating binder and the conductive polymer material are mixed to form the binder layer 315, May be formed.

3C, the motion recognition fabric sensor 1000 does not form a conductive material layer 300 on only one side of the lower fabric layer 200, but rather a conductive material layer 300a , And 300b can be formed. Each of the conductive material layers 300a and 300b includes a plurality of conductive nanoparticle layers 310 and 330 and an intermediate fabric layer 320 described with reference to FIG. 3B, and a binder layer 315 .

As such, the motion recognition fabric sensor 1000 according to various embodiments of the present invention is a motion recognition fabric sensor coated with conductive materials, integrated with conventional garments to provide a wearer of the garment (user) And is attached to the body of the wearer so as 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 4 and 5 illustrate a portion of an apparel system that includes an action recognition fabric sensor for measuring a user's actions in accordance with one embodiment of the present invention.

1 to 4, a garment system incorporating motion recognition fabric sensor 1000 includes a garment fabric layer 10, a lower fabric layer 200, a conductive material layer 300, and an insulating upper fabric layer 500 ). The garment fabric layer 10 basically represents the fabric layer constituting the garment and may comprise cotton, hemp, dog, nylon, polyester, acrylic, polyurethane, PVC, PCB, PP or combinations thereof.

The lower fabric layer 200 may have the same configuration, materials, and functionality as the lower fabric layer 200 described above with reference to FIGS. 1-3. Although not shown, a padding layer 100 may further be included between the lower fabric layer 200 and the garment fabric layer 10.

In one embodiment, the garment fabric layer 10 and the lower fabric layer 200 may be constructed of the same material. If the materials of the clothing fabric layer 10 and the bottom fabric layer 200 are the same, then a motion recognition fabric sensor is engaged and a portion of the area of the garment fabric layer 10 corresponding to the area, And may be used as a lower fabric layer on which the conductive material layer 300 is coated as the fabric layer 200. In this case, a padding layer 100 may further be included between body parts that are in contact with corresponding areas of the garment fabric layer 10.

The conductive material layer 300 may be coated on the lower fabric layer 200. As described above, when replacing the lower fabric layer 200 with the fabric layer 10, the conductive material layer 300 is coated on the clothing fabric layer 10 to the position and size of the area requiring motion sensing . In addition, an insulating top fabric layer 500 may be formed on the conductive material layer 300. The lower fabric layer 100, the conductive material layer 300 and the insulating upper fabric layer 500 described with reference to FIG. 4 are the same as the lower fabric layer 100, the conductive material layer 300, and the insulating upper fabric layer 500 may be identical in construction, material, and function.

In addition, the operation recognition fabric sensor 1000 of the garment system according to an embodiment of the present invention may be disposed at a position spaced apart from the area where the user's operation occurs on the garment system. When the motion recognition fabric sensor 1000 is coupled to the garment such that the center of the motion recognition fabric sensor 1000 corresponds to the center of the joint where the motion occurs, 1000 can be extended with only a portion of the motion recognition fabric sensor 1000 such that the center portion of the motion recognition fabric sensor 1000 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 operation recognition fabric sensor 1000. Therefore, it is necessary to incorporate the motion recognition fabric sensor 1000 at a location spaced from the area where the motion occurs.

In addition, the result of capturing the motion shows that the body surface of the joint part is extended most in the human body during operation, but it is confirmed that the most distant position from the joint part is elongated in the clothes. Therefore, by disposing the motion recognition fabric sensor 1000 at a position spaced apart 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 1000 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 recognizing fabric sensor 1000 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 . Also, when the position of the motion recognition fabric sensor 1000 is coupled to the garment area at a location spaced 15 cm away from the center of the joint, the degree of stretching of the garment and motion recognition fabric sensor 1000 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 1000 may be provided with a first motion recognition fabric sensor for measuring the motion in the vertical direction in the gravitational 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 waist line of the garment, and the second motion recognition fabric sensor is coupled to the garment area at a position 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 the garment system incorporating the motion recognition fabric sensor 1000, the motion recognition fabric sensor 1000 is coupled to the garment system without distortion of the position in the garment system where the noise can be measured, It is important to measure motion. The garment system may further include one or both of the spacing position holding portion 3000 and the close band structure 4000 in order to prevent the deviation of the motion recognition fabric sensor 1000 from the engagement position.

Referring to FIG. 4, the spacing position holder 3000 may be coupled to at least one end of the motion recognition fabric sensor 1000, and the motion recognition fabric sensor 1000 may be moved from the area where the user's motion occurs And can be connected to maintain its position. The spacing position holding unit 3000 is made of a non-stretchable material, so that the position of the motion recognition fabric sensor 1000 can be fixed even during operation of the user. In one embodiment, the spacing position holding portion 3000 may be a rectangular tape structure, a cord or a spiral shape showing a structure in which the spacing position holding portion has a thin thickness and a rectangular shape such as a tape And a twisted structure composed of a plurality of cords having a twisted shape in which a plurality of cords or strings are twisted with each other.

Referring to FIG. 5, the garment system may further include a close band structure 4000 to prevent positional deformation of the motion recognition fabric sensor 1000. The close band structure 4000 may be connected to one end of the motion recognition fabric sensor 1000 or to one end of the garment system. For example, when the motion recognition fabric sensor 1000 is disposed at the lower end of the elbow, the intimate band structure 4000 may be formed in the cuff or shoulder joint region of the garment system.

In this case, since the motion recognition fabric sensor 1000 is increased in extension by the close-contact band structure 4000, the size of the operation signal is increased, and the motion recognition fabric sensor 1000 is moved from a position It is possible to reduce the noise or the double peak signal generated in the operation signal measurement.

FIGS. 6A and 6B show results of measurement of an operation signal according to the position of the motion recognition fabric sensor 1000 according to an embodiment of the present invention. Referring to FIG. 6A, when the motion recognizing cloth sensor 1000 is attached to an elbow joint region where an action occurs, the size of the measured resistance forms a double peak. Such a double peak makes it impossible to accurately recognize the resistance value measured by the operation, so that the degree of the operation can not be accurately grasped. However, referring to FIG. 6B, when the motion recognizing cloth sensor 1000 recognizes the motion by attaching the center of the sensor in the longitudinal direction from the elbow joint region, which is the joint region where the motion occurs, at a position about 10 cm away from the wrist, It can be seen that no double peak occurs in the measurement resistance result value. Therefore, the motion recognition fabric sensor 1000 can measure the motion at a position spaced apart from the joint region where the motion occurs to recognize the degree of correct motion.

Fig. 7 shows the result of measuring the operation signal in the garment system (Series 1) not including the close band structure and the garment system including the fabric sensor 1000 and the close band structure 4000 described with reference to Fig. 5 Lt; / RTI >

Referring to FIG. 7, it can be seen that the magnitude of the resistance (Series 2) measured at the fabric sensor by operation when the user wearing the garment system including the tight band structure 4000 is operating does not include the close band structure Which is larger than the magnitude of the resistance (Series 2) measured by the operation of the wearing system of the wearer. Thus, a garment system including a closely spaced band structure 4000 according to an embodiment of the present invention can enable more accurate measurements for small operations.

Figure 8 is a schematic diagram of an operational signal sensing system that is provided with an operational signal from a garment system having a motion recognition fabric sensor in accordance with the present invention, including an operational recognition fabric sensor 1000, a garment system 2000, a communication module 5000, And an operation signal processing apparatus 6000.

The garment system 2000 includes the motion recognition fabric sensor 1000 according to various embodiments of the present invention described with reference to Figs. 1 to 3C and the spaced position retaining portion and / Structure. The details of the garment system 2000 are the same as those described above, and a detailed description thereof will be omitted.

The motion recognition fabric sensor 1000 includes a padding layer for reducing noise generated during operation, a lower fabric layer formed on the padding layer, a conductive material layer coated on the lower fabric layer, a signal measured on the conductive material layer A conductive interconnection further comprising at least one of a signal transfer interconnection for transferring the conductive material layer and a power supply interconnection for supplying power to the conductive material layer, . The contents of the motion recognition fabric sensor 1000 are the same as those described above, and therefore, detailed description thereof will be omitted.

The communication module 5000 transmits the result sensed by the operation recognition fabric sensor 1000 to the operation signal processor 6000 through the wired / wireless network. Here, the wired network may include a local area network (LAN), a wide area network (WAN), or a wired Internet. In addition, the wireless network may be a portable Internet such as wireless Internet such as WiFi (wireless fidelity), wireless broadband internet (WiBro) or world interoperability for microwave access (WiMax), a wideband code division multiple access (WCDMA) , A 4G mobile communication network such as an LTE (Long Term Evolution) network or an LTE-Advanced network, and a 5G mobile communication network. The communication module 5000 supports a communication protocol for a wired network or a wireless network.

The operation recognition fabric sensor 1000 is connected to the communication module 5000 of the garment system 2000 via a wired or wireless network and receives the biometric sense signal sensed by the human body from the communication module 5000. The operation signal processor 6000 may analyze the received biosensor signal using a bio-signal analysis program and stored data, and may transmit the analyzed processing signal to the apparel system 2000 through a wired / wireless network.
