Description

Technical Field

[0001] The present invention relates to clothing for measuring biological signals, which includes electrodes, wiring, and connectors and can be used as a wearable device for acquiring signals obtained from a biological body through an electronic device worn on the human body. Background Art

[0002] In recent years, the importance of daily health management has been recognized. As one of the methods for this, long-term recording and analysis of bioelectrical signals, such as electrocardiograms, is known to be effective in preventive medicine for early detection of troublesome physical discomfort and heart disease symptoms. Consequently, clothing equipped with sensors and electronic devices for long-term bioelectrical signal acquisition has attracted considerable attention (see Non-Patent Document 1).

[0003] It is necessary to fix or connect an electronic device for processing and recording electrical signals or transmitting signals to the outside to the clothing on which the sensor is installed. It is further necessary to have wiring for electrically conducting the electronic device with the electrodes, and a connector for connecting the wiring and the electronic device.

[0004] Examples of wiring and connector technologies include: a sensor fabricated from a conductive resin sheet containing conductive fine particles, formed into electrodes and wiring, which are attached to the skin side of a shirt. Metal snaps are attached between the ends of the wiring and the shirt's surface to create a connection, thereby connecting the sensor to an electronic device serving as a heart rate sensor (Patent Document 1). Another example involves attaching fiber electrodes impregnated with conductive resin and a conductor connected to the electrodes at their ends to form wiring, to the skin side of clothing. The wiring is then coated with a waterproof and insulating material, and the other end of the wiring is connected to a connector to provide electrical connection to the electronic device (Patent Document 2).

[0005] In any case, if the wiring part that transmits biological signals comes into contact with the skin or other objects, noise will be mixed into the biological signals, so it is necessary to cover it with a waterproof insulating member.

[0012] Problems to be solved by the invention

[0013] However, biological signal measurement clothing with waterproof wiring on the skin-facing side suffers from poor wearing comfort, such as heat rash caused by sweat accumulation and discomfort caused by the insulation material sticking to the skin, due to the insulated material's lack of water absorption. Meanwhile, wiring with waterproof wiring on the outer surface can cause the following problems.

[0014] Components used as connectors for connecting sensors, electrodes, wiring, and electronic devices need to be fixed to the fabric that is the basic material of clothing. Therefore, as clothing parts, most of them use conventional metallic objects called snaps or buckles, or the following metal materials in the same form, which are formed by a surface material for connecting to the outside and a back material arranged on the opposite side of the surface material with a base material such as cloth sandwiched therebetween. By external force, a part of the back side component penetrates the cloth and deforms inside the surface material, so that the two components are fixed with the cloth sandwiched therebetween.

[0015] In this case, in order to ensure sufficient electrical continuity between the wiring and the metal connector, it is important that the wiring be in direct contact with the metal connector over a large area. Furthermore, since the wiring needs to be insulated from skin and wet clothing, it must be covered with a waterproof insulating material, and the contact portion between the wiring and the metal connector must be free of insulating material.

[0016] Figure 7 This is a schematic diagram showing an example of the structure of a metal connector and the arrangement of wiring. Figure 8-1 and Figure 8-2 This is a diagram showing an example of the arrangement structure of the wiring (arranged on the skin surface) and the outer surface side and skin surface side of the metal connector that is not based on the present invention. Figure 7 A column-type metal connector 13-1 and a tooth-type metal connector 13-2 are exemplified and shown. Figure 8-1 and Figure 8-2 The electrode 10, the wiring 11, the insulating material 12a, 12b, the surface material 13a, and the back material 13b are shown in the figure over time. Figure 8-1 (a) and Figure 8-2 As shown in (a), first, the electrode 10 and the wiring 11 are installed on the back surface 2b. Figure 8-1As shown in (b), the insulating material 12a is installed on the outer surface 2a, as shown in FIG. Figure 8-2 As shown in (b), the surface material 13a and the back material 13b are attached to the main body 2 of the garment. Figure 8-1 (c) and Figure 8-2 As shown in (c), the insulating material 12b is attached to the back surface 2b.

[0017] like Figure 7 As shown, when the surface material 13a of the metal connectors 13-1 and 13-2 is mounted toward the outer surface 2a of the garment body 2 in order to mount the electronic device, the back material 13b of the metal connectors 13-1 and 13-2 is necessarily fixed to the skin surface 2b side. As long as the back material 13b is in direct contact with the wiring 11 disposed on the same surface as the skin surface 2b side, Figure 8-1 、 Figure 8-2 As shown, the metal connector 13 can be mounted in a state where the back surface material 13b is in contact with the wiring 11, and further, both the wiring 11 and the bottom of the back surface material 13b are covered with the insulating material 12b.

[0018] Figure 9-1 and Figure 9-2 This is a diagram showing an example of the arrangement structure of the wiring (outer surface arrangement) and the outer surface side and the skin surface side of the metal connector not based on the present invention. Figure 10 for Figure 9-1 An enlarged view of the wiring and connector arrangement structure. Figure 9-1 and Figure 9-2 The installation of the electrode 10, the wiring 11, and the insulating material 12a and 12b is shown in FIG. Figure 9-1 (a) and Figure 9-2 As shown in (a), first, the electrode 10 is mounted on the back surface 2b, the wiring 11 is mounted on the outer surface 2a, and the electrode 10 and the wiring 11 are connected with metal connectors 14a and 14b. Figure 9-1 (b) and Figure 9-2 As shown in (b), the insulating material 12a is installed on the outer surface 2a and the surface material 13a and the back material 13b are installed on the main body 2 of the clothing. Figure 9-1 (c) and Figure 9-2 As shown in (c), the insulating material 12b is attached to the back surface 2b.

[0019] Even when the wiring 11 and the surface material 13a of the metal connector 13 are arranged on the same outer surface 2a, the wiring 11 needs to be covered with the insulating material 12a, and a hole 12c needs to be opened in the insulating material 12a so that the surface material 13a is exposed through the hole 12c, so that the metal connector 13 can function as a connector. Figure 10As shown in (b), in order to improve the conductivity, the hole 12c of the insulating material 12a is enlarged, and the wiring 11 next to the metal connector 13 is exposed. Figure 10 In order to ensure insulation, as shown in (c), after attaching the insulating material 12a, the surface material 13a of the metal connector 13 is fixed from above. However, electrical continuity cannot be ensured. In addition, even if the hole 12c in the insulating material 12a is small enough to be hidden under the surface material 13a of the metal connector 13, there is a possibility that the contact between the metal connector 13 and the wiring 11 is insufficient, resulting in a poor connection.

[0020] The present invention is completed in view of the above-mentioned problems, and its purpose is to provide clothing for measuring biological signals that has excellent comfort, conductivity and insulation by allowing the wiring arranged on the outer surface side of the main body of the clothing to be arranged on the skin side through the incision portion provided in the main body of the clothing.

[0021] Means for solving problems

[0022] The present invention is clothing for measuring biological signals, which comprises: a clothing main body; an electrode, which is used in close contact with the skin surface of the aforementioned clothing main body; a wiring, which is arranged on the outer surface side of the aforementioned clothing main body and is connected to the aforementioned electrode at one end; a metal connector, which includes a surface material and a back material, and the other end of the aforementioned wiring is electrically connected by the engagement of the aforementioned surface material and the aforementioned back material, and an electronic device is connected to the aforementioned surface material; an insulating material, which seals the aforementioned wiring and the back material of the aforementioned metal connector, wherein the aforementioned wiring is arranged on the skin surface side via a cutout provided in the aforementioned clothing main body, and is directly contacted with the back material of the aforementioned metal connector that passes through the surface and back of the aforementioned clothing main body to be connected, and the aforementioned insulating material also seals the aforementioned cutout.

[0023] Furthermore, in the clothing for measuring biological signals, by sewing the fabric portion covering the wiring arranged on the outer side of the main body of the clothing to the front and back bodies, the wiring and insulating material cannot be seen from the surface side when worn, thus becoming a clothing for measuring biological signals with high design.

[0024] Furthermore, the clothing for measuring biological signals is characterized in that the front body of the aforementioned clothing main body includes a right front body and a left front body, and the aforementioned right front body and the aforementioned left front body can be opened and closed, wherein the aforementioned electrodes, the aforementioned wiring, and the aforementioned metal connector are respectively provided on the aforementioned right front body and the aforementioned left front body, so that the metal connectors of the aforementioned right front body and the aforementioned left front body span the opening and closing parts of the aforementioned right front body and the aforementioned left front body to connect to the aforementioned electronic device.

[0025] Furthermore, the biological signal measuring clothing includes an adapter having a first connector for connecting the electronic device on the front side and a second connector for connecting to the metal connector on the back side, thereby making it possible to easily attach the electronic device to the front of the body.

[0026] Furthermore, in the clothing for measuring biological signals, the adapter has an adapter main body composed of a textile, which is formed by folding the textile in half. The first connector and the second connector are provided on one side of the textile, and a wiring connecting the first connector and the second connector is provided on the opposite side. The wiring is sealed with an insulating material, and the adapter main body is folded in half so that the first connector and the second connector are exposed on both sides respectively.

[0027] Effects of the Invention

[0028] According to the biological signal measuring clothing of the present invention, the wiring can be arranged on the outer surface side of the clothing body so as not to contact the skin and can be reliably connected to the metal connector, thereby improving design and functionality.

[0029] In addition, the biological signal measurement clothing with a front opening structure based on the present invention is very easy to put on and take off and is easy to install electronic equipment, thereby reducing the wearer's discomfort when putting on and taking off, and preventing damage to the wiring caused by forcibly passing through the body when putting on and taking off.

[0045] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these examples.

[0046] [First embodiment]

[0047] Figure 1 This is a schematic diagram of an example of biological signal measurement clothing according to the first embodiment of the present invention. Figure 2-1 This is a partial view showing a wiring structure on the outer surface side of the biological signal measurement clothing according to the first embodiment of the present invention. Figure 2-2 This is a partial view showing the wiring structure on the skin-facing side of the biological signal measurement clothing according to the first embodiment of the present invention. Figure 2-1 and Figure 2-2 The diagram illustrates the installation of electrodes 10, wiring 11, and insulating materials 12a and 12b over time. In the biosignal measuring garment 1, electrodes 10 are provided on the skin surface of the garment body 2, below the chest near the ribs. One end of the wiring 11 is connected to the electrode 10. The wiring 11 is provided on the outer surface 2a of the garment body 2 and is electrically connected to the electrode 10 provided on the skin surface via a connector 14 (14a, 12b) having a structure consisting of a surface material and a back material similar to the metal connector 13 described later. The entire wiring 11 is covered with insulating materials 12a and 12b.

[0048] In the present invention, the material of the garment body 2 can be any natural fiber material such as cotton and wool, or synthetic fiber material such as polyester and nylon, which are commonly used in clothing products.

[0049] The raw material of the electrode 10 is not particularly limited. Commercially available medical Ag / AgCl electrodes with electrolyte paste, carbon filler mixed resin, Ag cloth, fabric impregnated with a conductive polymer, fabric impregnated with an electrolyte solution, etc. can be used without particular limitation. Preferably, the electrode 10 is made of fabric impregnated with a conductive polymer to reduce irritation to the skin in close contact and improve durability.

[0050] The electrodes 10 are arranged at two positions across the heart on the skin surface 2b side of the main body 2 of the clothing. They can measure the cardiac potential and heart rate by measuring the potential difference from the heart. In addition, they can also be arranged at positions corresponding to the muscles of the human body such as the brachialis, abdominal muscles, and quadriceps femoris to obtain myoelectric potential.

[0051] Methods for securing the electrode 10 to the garment body 2 include, for example, sewing the electrode 10 to the garment body 2, bonding using a thermocompression bonding material, and printing a conductive material to serve as the electrode 10 directly on the garment body 2. Alternatively, a buckle may be provided at the location on the garment body 2 where the electrode 10 is secured to secure a detachable electrode 10.

[0052] While any known wiring material can be used as the wiring 11 without limitation, since it is placed in the garment body 2, it is important that it is soft and durable in washing. Furthermore, it is necessary to cover it with insulating materials 12a and 12b to prevent the transmission of signals from the human body, etc., other than where the electrodes 10 are located. Furthermore, it is preferable to further interpose insulating material between the garment body 2 and the wiring 11 to insulate the wiring 11 from the garment body 2 where it is placed.

[0053] A metal connector 13 is provided at the center of the chest of the garment body 2, connected to the other ends of the wires 11 extending from the electrodes 10. An electronic device 20 is mounted on the metal connector 13, which can obtain information on the potential difference from the heart measured by the electrodes 10 via the wires 11 and the metal connector 13. The electronic device 20 can be attached and detached from the surface material 13a of the metal connector 13 via a connector 21.

[0054] The metal connector 13 is not particularly limited as long as it is made of metal and engages the surface material 13a and the back material 13b from both sides of the clothing body 2, and penetrates a part of the material so that the surface and the back are connected. Figure 7 The metal connectors 13 - 1 and 13 - 2 having such a structure have good passability during the sewing process and are easy to handle.

[0055] Figure 1 In the clothing 1 for measuring biological signals, the wiring 11 is not arranged on the skin surface 2b of the main body 2 of the clothing, but on the outer surface 2a side which is the opposite side. Therefore, there will be no feeling of stuffiness or friction due to the direct contact between the wiring 11 and the insulating material 12a covering the wiring 11 and the skin.

[0056] In the present invention, in order to realize that the arrangement of the wiring 11 and the arrangement of the surface material 13a of the metal connector 13 for mounting the electronic device 20 are not arranged on the skin surface 2b of the clothing body 2 but on the outer surface 2a side, a cutout portion 2c is provided on the clothing body 2. The wiring 11 is exposed on the skin surface 2b side opposite to the outer surface 2a side through the cutout portion 2c (see Figure 2-1 (a) Figure 2-2 (a)). The wiring 11 and the cutout portion 2c provided on the outer surface 2a side of the clothing body 2 are covered with an insulating material 12a (see Figure 2-1 (b)). The wiring 11 exposed on the skin surface 2b side is directly in contact with the back material 13b of the metal connector 13, and the surface material 13a and the back material 13b are inserted and engaged with the clothing body 2 and the wiring 11, so that the wiring 11 and the metal connector 13 are connected (see Figure 2-1 (c) Figure 2-2The wiring 11 exposed on the skin surface 2b side is covered by the insulating material 12b together with the cutout portion 2c of the clothing body 2 and the back material 13b of the metal connector 13 (see Figure 2-2 (c)). The electronic device 20 is connected to the surface material 13a of the metal connector 13 exposed above the insulating material 12a. By making such a structure, it is possible to achieve both sufficient conduction between the wiring 11 and the metal connector 13 and sufficient insulation of the wiring.

[0057] The cutout 2c of the clothing body 2 for exposing the wiring 11 on the skin surface 2b side may be as follows. Figure 2-1 (a) Figure 2-2 (a) shows a hole for inserting the wiring 11. Alternatively, the cutout portion 2c may be replaced with a hole as shown in FIG. Figure 3-1 (a) Figure 3-2 In either case, both the prevention of unraveling and the improvement of strength are achieved, and the following is important: the cutout 2c or the hollow structure 2d between the wiring 11 and the main body 2 of the garment is covered by the insulating material 12a provided on the outer surface 2a side and the insulating material 12b provided on the skin surface 2b side, and the back material 13b of the metal connector 13 on the skin surface 2b side is also covered with the insulating material 12b from above after being connected to the wiring 11, with only the surface material 13a of the outer surface 2a being exposed.

[0058] On the other hand, as a biological signal measuring clothing not based on the present invention, if the wiring 11 is arranged on the skin surface 2b side, Figure 8-2 As shown in the figure, the insulating material 12b covering the wiring 11 is arranged on the skin surface 2b side. Therefore, the area of direct contact between the insulating material 12b and the skin becomes larger, and the feeling of stuffiness and friction becomes stronger. On the other hand, if the wiring 11 is arranged on the outer surface 2a side of the clothing body 2 so that it does not contact the skin, then Figure 9-1 As shown, the surface material 13a of the metal connector 13 is directly in contact with the wiring 11 for connection. However, the wiring 11 is completely covered by the insulating material 12a. Therefore, if the surface material 13a of the metal connector 13 is fixed from above after the insulating material 12a is attached, electrical continuity with the wiring 11 cannot be ensured. In addition, even if a small hole 12c is previously formed in the insulating material 12a, the contact between the metal connector 13 and the wiring 11 can easily become insufficient if the wiring 11 and the metal connector 13 are slightly offset. In addition, the production process requires time and effort, and production efficiency is reduced.

[0059] Alternatively, if the holes 12c of the insulating material 12a are enlarged to improve conductivity, the wiring 11 in front of the surface material 13a will inevitably be exposed due to insufficient insulation, causing noise and compromising the design. The biological signal measuring garment 1 of this first embodiment places the wiring 11 primarily on the outer surface 2a of the garment body 2. This reduces the stuffiness and friction caused by direct contact of the insulating material 12b with the skin. Furthermore, the wiring 11 is in direct contact with the back material 13b of the metal connector 13, providing electrical continuity with the metal connector 13. This allows the wiring 11 to be completely covered by the insulating materials 12a and 12b, maintaining high conductivity and insulation.

[0060] [Second embodiment]

[0061] Figure 4 This is a schematic diagram of an example of clothing for measuring biological signals based on the second embodiment of the present invention. Like the clothing for measuring biological signals 1 according to the first embodiment, which covers the wiring 11 arranged on the outer surface 2a side of the clothing main body 2, in the clothing for measuring biological signals 1A according to the second embodiment, the fabric portion 3 is sewn to the clothing main body 2. In this case, the wiring 11 is hidden under the fabric portion 3, so the design of the appearance is not impaired. By further arranging the metal connector 13 for connecting the electronic device 20 on the fabric portion 3, the installation and removal of the electronic device 20 will not be hindered. In addition, similarly to the clothing for measuring biological signals 1 according to the first embodiment, in the clothing for measuring biological signals 1A, the wiring 11 is arranged on the outer surface of the clothing main body 2, and one end of the wiring 11 is electrically connected to the electrode 10 arranged on the skin side through the connector. In addition, the other end of the wiring 11 is connected to the outer surface of the clothing main body 2 through the connector. Figure 4 The not-shown cutout or hollow structure is exposed on the skin side and directly contacts the back material of the metal connector 13, thereby conducting the wiring 11 and the metal connector 13. The cutout or hollow structure and the back material of the metal connector 13 are covered with an insulating material.

[0062] Furthermore, if the fabric portion 3 covers not only the wiring 11 but also the electrodes 10 disposed on the skin surface 2b, even if the elasticity of the garment body 2 is relaxed, the portion where the garment body 2 and the fabric portion 3 are superimposed to form two layers can still produce an effect in which the electrodes 10 are closely attached to the skin and are not easily displaced, thereby further improving the signal acquisition performance and wearing comfort of the biological signal measurement clothing 1A. The fabric portion 3 and the garment body 2 can be made of the same material or different materials. Furthermore, if the fabric portion 3 is formed into a strip that covers the back surface of the garment body 2 to form a double layer, only the necessary portion around the entire circumference of the garment body 2 is two layers, thereby further improving the elasticity of the biological signal measurement clothing 1A that abuts and secures the electrodes 10 against the skin, thereby improving the signal acquisition performance. In addition, similar to embodiment 1, since the wiring 11 is arranged on the outer surface side, the area where the insulating material directly contacts the skin is reduced, which can reduce the stuffiness and friction caused by the insulating material, and at the same time can take into account sufficient conduction between the wiring 11 and the metal connector 13, and sufficient insulation of the wiring.

[0063] [Third embodiment]

[0064] Figure 5-1 This is a schematic diagram showing a biological signal measuring garment according to a third embodiment of the present invention. The front body of the garment main body 2 of the biological signal measuring garment 1B includes a right front body 2-1 and a left front body 2-2. An openable and closable zipper 4 is provided between the right front body 2-1 and the left front body 2-2, and electrodes 10, wiring 11, and metal connectors 13 are provided on the right front body 2-1 and the left front body 2-2, respectively. In addition, in the biological signal measuring garment 1B, similarly to the biological signal measuring garment 1 according to the first embodiment, the wiring 11 is provided on the outer surface of the garment main body 2, and one end of the wiring 11 is electrically connected to the electrode 10 provided on the skin side through a connector. In addition, the other end of the wiring 11 is connected to the skin side through a connector. Figure 5-1 The not-shown cutout or hollow structure is exposed on the skin side and directly contacts the back material of the metal connector 13, thereby conducting the wiring 11 and the metal connector 13. The cutout or hollow structure and the back material of the metal connector 13 are covered with an insulating material.

[0065] The electronic device 20 can be connected to the metal connectors 13 of the right front body 2-1 and the left front body 2-2 in the form of crossing the zipper 4. Even if the biological signal measurement clothing 1B is a tight-fitting garment made of a highly elastic fabric for the clothing body 2 in order to pursue close contact between the electrode 10 and the skin, it is very easy to put on and take off. In addition, even if the fabric sticks to the skin due to sweating, it is easy to take off. In addition, the chest area has strong elasticity and does not need to be worn over the head and shoulders, so it has the advantage of being easy to wear. In addition, as in embodiment 1, since the wiring 11 is arranged on the outer surface side, the area of direct contact between the insulating material and the skin is reduced, which can reduce the stuffiness and friction caused by the insulating material, and at the same time, it can take into account sufficient conduction between the wiring 11 and the metal connector 13 and sufficient insulation of the wiring. As Figure 5-2 The illustrated biosignal measurement garment 1C has the same structure as the biosignal measurement garment 1B, except that the fabric portion 3 is sewn together to conceal the wiring 11. This garment can be fully opened at the front. In addition to achieving the same benefits as the biosignal measurement garment 1B, it also boasts superior design and signal acquisition performance.

[0066] [Fourth embodiment]

[0067] Figure 6 Schematic diagram showing biological signal measurement clothing and an electronic device according to a fourth embodiment of the present invention. Figure 6 Shown Figure 5-1 The biological signal measuring clothing 1C is in a state where the adapter 30 is installed.

[0068] The adapter 30 has a first connector 32 connected to the connector 21D of the electronic device 20D on the surface of the adapter body 31 , and a second connector 33 connected to the surface material 13 a of the metal connector 13 on the back side.

[0069] In the biosignal measurement garments 1B and 1C, which can be fully opened at the front using a zipper or the like, the zipper increases the distance between the metal connectors 13 to a certain value or greater. This shortens the distance between the connectors of the intended electronic device, making direct installation impossible. Furthermore, other electronic devices with different connector configurations may need to be installed. By attaching an adapter 30 using a first connector 32 corresponding to the connector of the intended electronic device to the biosignal measurement garment 1C, electronic devices that cannot be directly connected to the metal connector 13 can be installed.

[0070] The adapter 30 can be a base comprising a first connector 32, a second connector 33, and wiring (not shown) attached to an adapter body 31 formed of a plastic or rubber sheet, or it can be an item made of a textile such as a woven or non-woven fabric. Particularly preferred is an item made of a textile folded in half, comprising the adapter body 31. A textile adapter with the first connector 32 and the second connector 33 on one side of the textile and the wiring on the opposite side, sealed with insulating material, and then folded so that the first connector 32 and the second connector 33 are exposed on each side of the folded textile, is suitable for direct attachment to clothing that rests close to the body because the wiring is not exposed and the textile is soft to the touch.

[0071] Industrial applicability

[0072] The present invention can be applied to a technology for acquiring biological electrical signals by wearing clothes equipped with electronic devices.
