FIG. 1 is a diagram showing a biometric data acquisition sheet 100 of the embodiment. FIG. 2 is a view showing a cross section taken along the line AA in FIG. FIG. 3 is a diagram showing a state in which the biometric data acquisition sheet 100 is disassembled. Below, it demonstrates using an XYZ coordinate system. Further, the plan view refers to an XY plane view. In the following, the living body is a human body as an example. In addition, the biological signal is a signal (typically, a voltage signal) representing an electrocardiographic waveform as an example, and the biological data is data representing a biological signal as an example.
　生体データ取得シート１００は、シート１１０、一対の電極１２０、及び、一対の導電性面ファスナ１３０を含む。 The biometric data acquisition sheet 100 includes a sheet 110, a pair of electrodes 120, and a pair of conductive surface fasteners 130.
　シート１１０は、一例として樹脂製で伸縮性を有するフィルムタイプのシートであり、－Ｚ方向側の表面に粘着剤層１１１を有する。－Ｚ方向側の表面は、第１面の一例である。シート１１０は、一例として生体の胸部に貼り付けられるため、肌の凹凸に応じて伸縮可能なシート状の部材であることが好ましく、例えば、ポリウレタンエラストマーや非塩化ビニール系のポリオレフィン等を用いることができる。また、粘着剤層１１１は、例えばアクリル系粘着剤を用いることができる。シート１１０の厚さは、一例として０．０１ｍｍ～０．５ｍｍである。 The sheet 110 is, for example, a film type sheet made of resin and having elasticity, and has an adhesive layer 111 on the surface in the −Z direction. The surface on the −Z direction side is an example of the first surface. The sheet 110 is, for example, attached to the chest of a living body, and thus is preferably a sheet-shaped member that can expand and contract according to the unevenness of the skin. For example, a polyurethane elastomer or a non-vinyl chloride-based polyolefin is used. it can. The pressure-sensitive adhesive layer 111 can use, for example, an acrylic pressure-sensitive adhesive. The thickness of the sheet 110 is, for example, 0.01 mm to 0.5 mm.
　シート１１０は、肌の凹凸形状等への追従性、保形性（形状を保持する性質）の高さ、肌触りの良い触感、及び、粘着剤層１１１の付き易さを有していればよい。粘着剤層１１１を有するシート１１０としては、例えば、積水化学工業株式会社の4891HT（ポリエチレンフィルム基材）、日東電工株式会社のベタ４アイ（ポリプロピレン製の不織布基材）、スリーエム（３Ｍ）社の1533L（レーヨン不織布基材）を用いることができる。 The sheet 110 only needs to have conformability to the uneven shape of the skin and the like, high shape retention (property to retain the shape), comfortable touch, and ease of attaching the adhesive layer 111. .. Examples of the sheet 110 having the pressure-sensitive adhesive layer 111 include Sekisui Chemical Co., Ltd.'s 4891HT (polyethylene film base material), Nitto Denko Corporation's Solid 4 Eye (polypropylene non-woven base material), and 3M (3M) company. 1533L (rayon non-woven fabric substrate) can be used.
　シート１１０は、一例として平面視で矩形状であり、Ｘ方向に配列される２つの開口部１１０Ａを有する。また、粘着剤層１１１は、２つの開口部１１０Ａと同一サイズで同一の位置に設けられる２つの開口部１１１Ａを有する。 The sheet 110 has, for example, a rectangular shape in a plan view, and has two openings 110A arranged in the X direction. The pressure-sensitive adhesive layer 111 has two openings 111A that have the same size and are provided at the same positions as the two openings 110A.
　シート１１０の２つの開口部１１０Ａは、シート１１０のＸ軸方向における中心の両側に設けられており、粘着剤層１１１の２つの開口部１１１Ａは、粘着剤層１１１のＸ軸方向における中心の両側に設けられている。開口部１１０Ａ、１１１Ａには導電性面ファスナ１３０が１つずつ設けられている。 The two openings 110A of the sheet 110 are provided on both sides of the center of the sheet 110 in the X-axis direction, and the two openings 111A of the adhesive layer 111 are on both sides of the center of the adhesive layer 111 in the X-axis direction. It is provided in. One conductive surface fastener 130 is provided in each of the openings 110A and 111A.
　電極１２０は、一例として銀繊維製である。銀繊維とは、フィラメント糸に銀メッキを施したものや、不織布又は織布等の布地の全体に銀メッキを施したものである。電極１２０は、平面視で矩形状であり、シート１１０及び粘着剤層１１１の開口部１１０Ａ及び１１１Ａよりも大きい。なお、電極１２０は、銀繊維にゲル等を塗布したウェット型の電極であってもよい。また、電極１２０は、銀メッキを施した銀繊維製に限らず、金等の銀以外の金属メッキを施した繊維製であってもよい。また、電極１２０は、繊維製のものに限らず、その他の形態の電極であってもよい。 The electrode 120 is made of silver fiber as an example. The silver fiber is a filament yarn plated with silver, or a whole fabric such as a non-woven fabric or a woven fabric is plated with silver. The electrode 120 has a rectangular shape in a plan view and is larger than the openings 110A and 111A of the sheet 110 and the adhesive layer 111. The electrode 120 may be a wet type electrode in which gel or the like is applied to silver fiber. Further, the electrode 120 is not limited to the silver-plated silver fiber, but may be a metal-plated fiber other than silver such as gold. Further, the electrode 120 is not limited to the one made of fiber, and may be an electrode of another form.
　電極１２０は、２つ（一対）設けられており、シート１１０の－Ｚ方向側の粘着剤層１１１に、平面視でそれぞれ２つの開口部１１０Ａ及び１１１Ａと重なるように貼り付けられている。このため、導電性面ファスナ１３０を取り付けていない状態では、電極１２０は、＋Ｚ方向側から見ると開口部１１０Ａ及び１１１Ａから表出する。電極１２０の厚さは、一例として０．１ｍｍ～１０ｍｍである。 Two electrodes (a pair) are provided, and they are attached to the adhesive layer 111 on the −Z direction side of the sheet 110 so as to respectively overlap with the two openings 110A and 111A in a plan view. Therefore, when the conductive surface fastener 130 is not attached, the electrode 120 is exposed from the openings 110A and 111A when viewed from the +Z direction side. The thickness of the electrode 120 is, for example, 0.1 mm to 10 mm.
　導電性面ファスナ１３０は、導電性を有するマジックテープ（登録商標）であり、２つの電極１２０に対応して２つ（一対）設けられている。導電性面ファスナ１３０は、基部１３１と起毛部１３２を有し、電極１２０の銀繊維と同様に、フィラメント糸に銀メッキを施した繊維や布帛に銀メッキを施したもので構成される。導電性面ファスナ１３０は、第１導電性面ファスナの一例である。 The conductive hook-and-loop fastener 130 is a conductive magic tape (registered trademark), and two (one pair) are provided corresponding to the two electrodes 120. The conductive hook-and-loop fastener 130 has a base portion 131 and a raised portion 132, and is composed of a fiber obtained by silver-plating a filament thread or a cloth obtained by silver-plating a cloth like the silver fiber of the electrode 120. The conductive hook-and-loop fastener 130 is an example of a first conductive hook-and-loop fastener.
　基部１３１は、平面視でシート１１０の開口部１１０Ａより少し小さなサイズを有する矩形状のナイロンやポリエステル等の化学繊維製の布地であり、銀メッキが全体に施されている。基部１３１は、平面視で開口部１１０Ａ及び１１１Ａの内部に配置される。基部１３１の＋Ｚ方向側の面には起毛部１３２が設けられている。導電性面ファスナ１３０は、一例としてメス型である。導電性面ファスナ１３０としてメス型を用いるのは、一般的に面ファスナはオス型よりメス型の方が柔らかいため、生体に貼り付けられる生体データ取得シート１００に、より適しているからである。 The base 131 is a rectangular fabric made of chemical fiber such as nylon or polyester having a size slightly smaller than the opening 110A of the sheet 110 in plan view, and is silver-plated on the whole. The base 131 is arranged inside the openings 110A and 111A in a plan view. A raised portion 132 is provided on the +Z direction side surface of the base 131. The conductive surface fastener 130 is, for example, a female type. A female type is used as the conductive hook-and-loop fastener 130 because, in general, the female fastener is softer than the male fastener, and is thus more suitable for the biometric data acquisition sheet 100 to be attached to a living body.
　基部１３１は、平面視でシート１１０及び粘着剤層１１１の開口部１１０Ａ及び１１１Ａと中心が合うように位置合わせをした状態で矩形環状の両面テープ１３５によって電極１２０に接合されている。すなわち、導電性面ファスナ１３０は、平面視で両面テープ１３５の中央にある開口部１３５Ａの内部では電極１２０に直接的に接続されている。なお、基部１３１の厚さは、一例として０．１ｍｍ～１ｍｍである。 The base 131 is joined to the electrode 120 with a rectangular annular double-sided tape 135 in a state of being aligned so as to be aligned with the openings 110A and 111A of the sheet 110 and the adhesive layer 111 in a plan view. That is, the conductive surface fastener 130 is directly connected to the electrode 120 inside the opening 135A at the center of the double-sided tape 135 in plan view. The thickness of the base 131 is, for example, 0.1 mm to 1 mm.
　両面テープ１３５は、平面視で基部１３１より少し小さい矩形状であり、中央に矩形状の開口部１３５Ａを有する。すなわち、両面テープ１３５は、平面視で矩形環状である。両面テープ１３５は、導電性を有していなくてよい。両面テープ１３５が開口部１３５Ａを有するのは、電極１２０と導電性面ファスナ１３０の基部１３１とを直接的に接続して電気的な接続を確保するためである。 The double-sided tape 135 has a rectangular shape that is slightly smaller than the base 131 in a plan view, and has a rectangular opening 135A in the center. That is, the double-sided tape 135 has a rectangular ring shape in a plan view. The double-sided tape 135 does not have to be electrically conductive. The double-sided tape 135 has the opening 135A for the purpose of directly connecting the electrode 120 and the base 131 of the conductive surface fastener 130 to ensure electrical connection.
　両面テープ１３５は、開口部１１０Ａ及び１１１Ａの内部で電極１２０及び基部１３１が重なり合う部分のうちの一部を貼り付けている。両面テープ１３５が貼り付けていない部分は、電極１２０と基部１３１とが直接接触するからである。 The double-sided tape 135 has a part of the portion where the electrode 120 and the base 131 overlap inside the openings 110A and 111A attached. This is because the electrode 120 and the base 131 are in direct contact with each other at the portion where the double-sided tape 135 is not attached.
　なお、両面テープ１３５は矩形環状に限らず円環状であってもよいし、環状ではなく、開口部１１０Ａ及び１１１Ａの内部で電極１２０及び基部１３１が重なり合う部分のうちの一部を貼り付ける矩形状やストライプ状等の形状であってもよい。 The double-sided tape 135 is not limited to a rectangular ring shape, but may be a circular ring shape. Instead of the ring shape, a rectangular shape in which a part of the overlapping portion of the electrode 120 and the base 131 inside the openings 110A and 111A is attached is attached. The shape may be a stripe shape or the like.
　また、両面テープ１３５として導電性を有する両面テープを用いる場合には、開口部１３５Ａを有していなくてもよい。 Further, when a conductive double-sided tape is used as the double-sided tape 135, the opening 135A may not be provided.
　また、ここでは両面テープ１３５を用いる形態について説明するが、基部１３１は、平面視でシート１１０及び粘着剤層１１１の開口部１１０Ａ及び１１１Ａと中心が合うように位置合わせをした状態で、導電性を有する接着剤を使って電極１２０と接合されてもよい。 In addition, here, a mode in which the double-sided tape 135 is used will be described. However, the base 131 is conductive so as to be aligned so as to be aligned with the openings 110A and 111A of the sheet 110 and the adhesive layer 111 in a plan view. It may be bonded to the electrode 120 using an adhesive having
　なお、両面テープ１３５を用いる場合は、導電性面ファスナ１３０と電極１２０とを接着剤で接合する場合に比べて、製造を簡略化できる。接着剤を使う場合は、接着剤が不要な場所に入り込まないように、注入量や注入位置を制御する必要がある。これに対し、両面テープ１３５を用いる場合は、接着剤に比べて簡単に製造できる。 When the double-sided tape 135 is used, the manufacturing can be simplified as compared with the case where the conductive surface fastener 130 and the electrode 120 are joined with an adhesive. When using an adhesive, it is necessary to control the injection amount and injection position so that the adhesive does not enter an unnecessary place. On the other hand, when the double-sided tape 135 is used, it can be manufactured more easily than the adhesive.
　起毛部１３２は、ナイロンやポリエステル等の化学繊維製であり、銀メッキが全体に施されている。起毛部１３２は、基部１３１が上述のように電極１２０に固定されることにより、開口部１１０Ａ及び１１１Ａから＋Ｚ方向に表出（露出）している。起毛部１３２は、シート１１０の＋Ｚ方向側の表面よりも＋Ｚ方向側に延在している。シート１１０の＋Ｚ方向側の表面は、第２面の一例である。なお、起毛部１３２の高さ（Ｚ軸方向の長さ）は、一例として、０．１ｍｍ～１０ｍｍである。 The brushed part 132 is made of chemical fiber such as nylon or polyester, and is silver-plated on the whole. The raised portion 132 is exposed (exposed) in the +Z direction from the openings 110A and 111A by fixing the base 131 to the electrode 120 as described above. The raised portion 132 extends on the +Z direction side of the +Z direction side surface of the sheet 110. The +Z direction side surface of the sheet 110 is an example of the second surface. The height (length in the Z-axis direction) of the raised portion 132 is, for example, 0.1 mm to 10 mm.
　図４は、実施の形態の生体データ取得装置３００を示す図である。図５は、図４のＢ－Ｂ矢視断面を示す図である。図４及び図５では、図１及び図２と同一のＸＹＺ座標系を用いて説明する。 FIG. 4 is a diagram showing a biometric data acquisition device 300 according to the embodiment. FIG. 5 is a view showing a cross section taken along the line BB of FIG. 4 and 5, the same XYZ coordinate system as that in FIGS. 1 and 2 will be used for description.
　生体データ取得装置３００は、生体データ取得シート１００及びトランスミッタ２００を含む。トランスミッタ２００は、データ送信装置の一例であり、送信機２１０と、導電性面ファスナ２２０とを有する。 The biometric data acquisition device 300 includes a biometric data acquisition sheet 100 and a transmitter 200. The transmitter 200 is an example of a data transmission device, and includes a transmitter 210 and a conductive surface fastener 220.
　送信機２１０は、筐体２１１、端子２１２、送信部２１３、及びバッテリ２１４を有する。筐体２１１は、直方体状のケースであり、－Ｚ方向側の表面に端子２１２が設けられるとともに、内部に送信部２１３が配置される。端子２１２は、送信部２１３に接続されており、生体データ取得シート１００から生体信号が入力される入力端子である。端子２１２には、導電性面ファスナ２２０が接続される。 The transmitter 210 has a housing 211, a terminal 212, a transmitter 213, and a battery 214. The casing 211 is a rectangular parallelepiped case, and the terminal 212 is provided on the surface on the −Z direction side, and the transmitting unit 213 is arranged inside. The terminal 212 is an input terminal that is connected to the transmission unit 213 and receives a biometric signal from the biometric data acquisition sheet 100. The conductive hook-and-loop fastener 220 is connected to the terminal 212.
　送信部２１３は、一例としてBluetooth（登録商標）規格の送信機器である。送信部２１３は、バッテリ２１４から供給される電力で駆動され、端子２１２を介して生体データ取得シート１００から取得する生体信号（生体データ）をデジタル変換して、生体データ取得シート１００及び／又は送信機２１０の識別子とともに送信する。 The transmitting unit 213 is, for example, a Bluetooth (registered trademark) standard transmitting device. The transmitter 213 is driven by the electric power supplied from the battery 214, converts the biometric signal (biometric data) acquired from the biometric data acquisition sheet 100 via the terminal 212 into a digital signal, and/or transmits the biometric data acquisition sheet 100 and/or the biometric data acquisition sheet 100. Machine 210 with the identifier of machine 210.
　送信機２１０は、生体データ取得シート１００によって取得される生体信号（生体データ）を導電性面ファスナ２２０を介して取得し、図示しないスマートフォン端末機、タブレットコンピュータ、又はＰＣ(Personal Computer)等の情報処理装置に無線で送信する。 The transmitter 210 acquires a biometric signal (biological data) acquired by the biometric data acquisition sheet 100 via the conductive surface fastener 220, and information such as a smartphone terminal device (not shown), a tablet computer, or a PC (Personal Computer). Wirelessly transmitted to the processing device.
　なお、送信機２１０は、無線通信で情報処理装置に生体信号（生体データ）を送信できる装置であればよく、一例としてBluetooth（登録商標）規格以外の無線通信の規格に対応したものであってもよい。例えば、３Ｇ(Third Generation)、ＬＴＥ(Long Term Evolution)、４Ｇ(Fourth Generation)、又は５Ｇ(Fifth Generation)等の公衆回線やＷＬＡＮ(Wireless Local Area Network)等であってもよい。 Note that the transmitter 210 may be any device that can transmit a biological signal (biological data) to the information processing device by wireless communication, and as an example, is compatible with a wireless communication standard other than the Bluetooth (registered trademark) standard. Good. For example, a public line such as 3G (Third Generation), LTE (Long Term Evolution), 4G (Fourth Generation), or 5G (Fifth Generation), a WLAN (Wireless Local Area Network), or the like may be used.
　導電性面ファスナ２２０は、導電性を有するマジックテープ（登録商標）であり、２つの導電性面ファスナ１３０に対応して２つ（一対）設けられている。導電性面ファスナ２２０は、基部２２１と起毛部２２２を有し、導電性面ファスナ１３０と同様に全体に銀メッキが施されている。導電性面ファスナ２２０は、一例としてオス型の面ファスナであり、第２導電性面ファスナの一例である。 The conductive surface fastener 220 is a magic tape (registered trademark) having conductivity, and two (a pair) provided corresponding to the two conductive surface fasteners 130. The conductive surface fastener 220 has a base portion 221 and a raised portion 222, and like the conductive surface fastener 130, is entirely plated with silver. The conductive hook-and-loop fastener 220 is, for example, a male hook-and-loop fastener and is an example of the second conductive hook-and-loop fastener.
　基部２２１は、平面視で導電性面ファスナ１３０の基部１３１と等しいサイズを有する矩形状のナイロンやポリエステル等の化学繊維製の布地であり、銀メッキが全体に施されている。基部２２１には、－Ｚ方向側の面に起毛部２２２が設けられている。基部２２１は、送信機２１０の筐体２１１の－Ｚ方向側の表面で端子２１２に接続された状態で、接着剤等によって筐体２１１の－Ｚ方向側の表面に貼り付けられている。２つの導電性面ファスナ２２０のＸ方向の間隔は、２つの導電性面ファスナ１３０のＸ方向の間隔と等しい。 The base 221 is a rectangular cloth made of chemical fiber such as nylon or polyester, which has the same size as the base 131 of the conductive surface fastener 130 in plan view, and is silver-plated on the whole. A raised portion 222 is provided on the surface of the base portion 221 on the −Z direction side. The base portion 221 is attached to the surface of the housing 211 on the −Z direction side with an adhesive or the like in a state of being connected to the terminal 212 on the surface of the housing 211 of the transmitter 210 on the −Z direction side. The distance between the two conductive surface fasteners 220 in the X direction is equal to the distance between the two conductive surface fasteners 130 in the X direction.
　起毛部２２２は、ナイロンやポリエステル等の化学繊維製であり、銀メッキが全体に施されている。起毛部２２２は、基部２２１が筐体２１１の－Ｚ方向側の表面に固定されることにより、筐体２１１の－Ｚ方向側に延在している。 The brushed part 222 is made of chemical fiber such as nylon or polyester, and is silver-plated on the whole. The raised portion 222 extends to the −Z direction side of the housing 211 by fixing the base 221 to the −Z direction side surface of the housing 211.
　このような導電性面ファスナ２２０を有するトランスミッタ２００は、導電性面ファスナ２２０の起毛部２２２を導電性面ファスナ１３０の起毛部１３２に係合させることによって、生体データ取得シート１００に取り付けられる。 The transmitter 200 having such a conductive surface fastener 220 is attached to the biometric data acquisition sheet 100 by engaging the raised portion 222 of the conductive surface fastener 220 with the raised portion 132 of the conductive surface fastener 130.
　生体データ取得シート１００を生体の胸部の肌に貼り付けると、電極１２０が胸部の肌に密着する。電極１２０は、導電性面ファスナ１３０、２２０を介してトランスミッタ２００の送信機２１０の端子２１２に接続されているため、送信機２１０は、電極１２０で取得される生体データを入手することができる。 When the biometric data acquisition sheet 100 is attached to the skin of the chest of the living body, the electrodes 120 adhere to the skin of the chest. Since the electrode 120 is connected to the terminal 212 of the transmitter 210 of the transmitter 200 via the conductive surface fasteners 130 and 220, the transmitter 210 can obtain the biometric data acquired by the electrode 120.
　以上のように、生体データ取得シート１００では、シート１１０は、ポリウレタンエラストマーや非塩化ビニール系のポリオレフィン等であり、粘着剤層１１１はアクリル系粘着剤等である。また、電極１２０は、銀繊維製であり、導電性面ファスナ１３０は、銀メッキが全体に施されたナイロンやポリエステル等の化学繊維製である。 As described above, in the biometric data acquisition sheet 100, the sheet 110 is a polyurethane elastomer, a non-vinyl chloride polyolefin, or the like, and the adhesive layer 111 is an acrylic adhesive or the like. The electrode 120 is made of silver fiber, and the conductive hook-and-loop fastener 130 is made of chemical fiber such as nylon or polyester which is entirely plated with silver.
　各部の材質として上述のような材質を用いているのは、生体データ取得シート１００を使い捨て型にするためである。生体データ取得シート１００は、分解して分別することなく、廃棄可能である。また、シート１１０、粘着剤層１１１、電極１２０、導電性面ファスナ１３０を可燃ゴミとして廃棄可能である場合には、生体データ取得シート１００をそのまま可燃ゴミとして廃棄可能である。 The above-mentioned materials are used as the material of each part in order to make the biometric data acquisition sheet 100 a disposable type. The biometric data acquisition sheet 100 can be discarded without disassembling and separating. When the sheet 110, the adhesive layer 111, the electrode 120, and the conductive surface fastener 130 can be discarded as combustible dust, the biometric data acquisition sheet 100 can be discarded as it is as combustible dust.
　したがって、簡単に廃棄できる生体データ取得シート１００を提供することができる。また、このように簡単に廃棄できる生体データ取得シート１００を含む生体データ取得装置３００を提供することができる。生体データ取得シート１００を使い捨て型にして、トランスミッタ２００は、例えばバッテリ２１４を交換又は充電して繰り返し利用すればよい。 Therefore, it is possible to provide the biometric data acquisition sheet 100 that can be easily discarded. Further, it is possible to provide the biometric data acquisition device 300 including the biometric data acquisition sheet 100 that can be simply discarded as described above. The biometric data acquisition sheet 100 may be a disposable type, and the transmitter 200 may be repeatedly used by exchanging or charging the battery 214, for example.
　また、生体データ取得シート１００は、シート１１０が生体の肌に直接的に貼り付けられるため、生体が激しい運動をしても、生体データ取得シート１００がずれることを抑制でき、電極１２０を一定の位置に貼り付けた状態を保持することができる。 Further, in the biometric data acquisition sheet 100, since the sheet 110 is directly attached to the skin of the biometric body, it is possible to prevent the biometric data acquisition sheet 100 from shifting even when the biometric body makes a vigorous exercise, and to keep the electrode 120 at a constant level. The state of being stuck to the position can be retained.
　このため、位置ずれ等によるノイズが生体信号に含まれることを抑制でき、状態の良好な生体信号（生体データ）を取得（検出）することができる。 Therefore, it is possible to suppress the noise due to the position shift and the like from being included in the biological signal, and it is possible to acquire (detect) the biological signal (biological data) in a good state.
　また、電極１２０が配線等を介すことなく導電性面ファスナ１３０に直接的に接続されているため、生体が激しい運動をしてもノイズが生体信号に含まれることを抑制でき、状態の良好な生体信号（生体データ）を取得（検出）することができる。例えば、電極１２０が配線を介して導電性面ファスナ１３０に接続されていると、配線が静電容量を有するため、生体が運動等を行って動くと、静電容量が変動して生体信号にノイズが含まれるおそれがある。 In addition, since the electrode 120 is directly connected to the conductive surface fastener 130 without any wiring or the like, it is possible to suppress the noise from being included in the biological signal even when the living body makes a vigorous exercise, and the state is good. It is possible to acquire (detect) various biological signals (biological data). For example, when the electrode 120 is connected to the conductive surface fastener 130 via a wire, the wire has an electrostatic capacity, and therefore when the living body moves or moves, the electrostatic capacity fluctuates to generate a biological signal. May contain noise.
　生体データ取得シート１００は、このような静電容量が変動によるノイズが生体信号に含まれることを抑制でき、状態の良好な生体信号（生体データ）を取得（検出）することができる。 The biometric data acquisition sheet 100 can suppress the inclusion of noise due to such variation in capacitance in the biometric signal, and can acquire (detect) a biometric signal (biometric data) in a good state.
　また、電極１２０の厚さを厚くすると、生体データ取得シート１００を生体に貼り付けたときに、電極１２０の厚さが薄い場合よりも電極１２０が肌に密着する力が強くなる。電極１２０が厚い分だけ、粘着剤層１１１によって生体の肌に貼り付けられるシート１１０によって生体の肌の方向に押圧される力が強くなるからである。このため、電極１２０の厚さは、粘着剤層１１１の粘着力を考慮して、最適な押圧力が得られるように設定してもよい。このように厚い電極１２０としては、例えば、３次元的に編み込んだ立体的な編み物や、３次元的に織り上げた立体的な織物に銀メッキを施した銀繊維を用いればよい。 Also, when the thickness of the electrode 120 is increased, the force with which the electrode 120 adheres to the skin when the biometric data acquisition sheet 100 is attached to a living body becomes stronger than when the electrode 120 is thin. This is because the thicker the electrode 120 is, the stronger the force of the sheet 110 attached to the skin of the living body by the adhesive layer 111 toward the skin of the living body becomes. Therefore, the thickness of the electrode 120 may be set in consideration of the adhesive force of the adhesive layer 111 so that an optimum pressing force can be obtained. As such a thick electrode 120, for example, a three-dimensionally knitted three-dimensional knitted fabric or a three-dimensionally woven three-dimensionally woven fabric and silver fibers plated with silver may be used.
　また、図１乃至図３に示すように両面テープ１３５で導電性面ファスナ１３０の基部１３１と電極１２０とを貼り合わせる代わりに糸で縫い合わせることも可能である。しかしながら、糸で縫い合わせる形態よりも、両面テープ１３５で貼り合わせる方が製造工程を少なくできる。糸で縫い合わせる工程は、導電性面ファスナ１３０と電極１２０を重ね合わせる工程とは別の工程になるためである。 Further, as shown in FIGS. 1 to 3, it is also possible to sew with a thread instead of sticking the base 131 of the conductive surface fastener 130 and the electrode 120 with the double-sided tape 135. However, it is possible to reduce the number of manufacturing processes when the double-sided tape 135 is used for bonding, as compared with the case where the threads are sewn together. This is because the step of sewing with thread is a step different from the step of overlapping the conductive surface fastener 130 and the electrode 120.
　したがって、両面テープ１３５を用いる場合には、製造工程を少なくでき、容易に製造することができる。 Therefore, when the double-sided tape 135 is used, the number of manufacturing steps can be reduced and the manufacturing can be easily performed.
　なお、生体データ取得シート１００を生体に貼り付ける前の状態では、シート１１０の粘着剤層１１１に保護フィルム等を貼り付けておけばよい。保護フィルムは、生体に貼り付ける際に容易に剥がせる構成であればよい。また、シート１１０の＋Ｚ方向側にも保護フィルム等を設けてもよい。 Note that, in a state before the biometric data acquisition sheet 100 is attached to the living body, a protective film or the like may be attached to the adhesive layer 111 of the sheet 110. The protective film may have a configuration that can be easily peeled off when it is attached to a living body. Further, a protective film or the like may be provided on the +Z direction side of the sheet 110.
　また、以上では、シート１１０が矩形状である形態について説明したが、シート１１０の平面視での形状は、楕円、菱形、平行四辺形等の様々な形状であってよい。 Although the sheet 110 has a rectangular shape in the above description, the shape of the sheet 110 in plan view may be various shapes such as an ellipse, a rhombus, and a parallelogram.
　また、以上では、生体データとして心電データを取得する形態について説明したが、脳波やその他の生体データであってもよい。 Also, in the above description, the form of acquiring electrocardiographic data as biometric data has been described, but it may be electroencephalogram or other biometric data.
　また、電極１２０として多孔質型のフィルム等を用い、生体の肌に貼り付けられる側の表面に撥水処理加工を施し、さらにアクリル系又はウレタン系樹脂をコーティング又はプリントしてもよい。このようにすれば、電極１２０と肌との密着性を向上させることができるとともに、肌の蒸れを抑制することができる。このような多孔質型のフィルムとしては、例えば、株式会社共和のポリウレタンフィルムを用いることができる。 Alternatively, a porous film or the like may be used as the electrode 120, the surface on the side to be attached to the skin of a living body may be subjected to a water repellent treatment, and further an acrylic or urethane resin may be coated or printed. In this way, the adhesion between the electrode 120 and the skin can be improved, and the stuffiness of the skin can be suppressed. As such a porous film, for example, a polyurethane film manufactured by Kyowa Co., Ltd. can be used.
　また、肌の蒸れを抑制するために、電極１２０として多孔質型のフィルムを用いる代わりに、透湿シートを用いてもよい。このような透湿シートとしては、例えば、湿気を通し、水は通さない微多孔質ポリオレフィン系フィルムを用いることができる。 Further, in order to suppress the stuffiness of the skin, a moisture permeable sheet may be used instead of the porous film as the electrode 120. As such a moisture permeable sheet, for example, a microporous polyolefin film that allows moisture to pass therethrough and does not allow water to pass therethrough can be used.
　また、図６に示す生体データ取得シート１００Ａのように電極１２０間の距離を長く取ってもよい。図６は、実施の形態の第１変形例の生体データ取得シート１００Ａを示す図である。生体データ取得シート１００Ａは、電極１２０間の距離を長く取ったこと以外は、図１乃至図５に示す生体データ取得シート１００と同様である。図６では、一例として電極１２０間の距離を図１の３倍程度にしてある。電極１２０間の距離は、検出される生体の心電波形の大きさが所定レベル以上となる距離である。所定レベルは、検出される心電波形の信号レベルが所定レベル以上になると、心電波形を検出する精度が高まるレベルである。電極１２０間の距離は、生体の胸部に貼り付ける位置や体格の大きさ等に応じて設定してもよい。 Also, the distance between the electrodes 120 may be set longer as in the biometric data acquisition sheet 100A shown in FIG. FIG. 6 is a diagram showing a biometric data acquisition sheet 100A of the first modified example of the embodiment. The biometric data acquisition sheet 100A is the same as the biometric data acquisition sheet 100 shown in FIGS. 1 to 5 except that the distance between the electrodes 120 is long. In FIG. 6, as an example, the distance between the electrodes 120 is about three times that in FIG. The distance between the electrodes 120 is a distance at which the magnitude of the detected electrocardiographic waveform of the living body becomes a predetermined level or more. The predetermined level is a level at which the accuracy of detecting the electrocardiographic waveform increases when the signal level of the detected electrocardiographic waveform becomes equal to or higher than the predetermined level. The distance between the electrodes 120 may be set according to the position to be attached to the chest of the living body, the size of the physique, and the like.
　また、図７に示す生体データ取得装置３００Ｂの生体データ取得シート１００Ｂのように、シート１１０Ｂに凸部１１２を設けてもよい。図７は、実施の形態の第２変形例の生体データ取得装置３００Ｂを示す図である。生体データ取得装置３００Ｂは、生体データ取得シート１００Ｂ及びトランスミッタ２００を含む。 Further, like the biometric data acquisition sheet 100B of the biometric data acquisition apparatus 300B shown in FIG. 7, the sheet 110B may be provided with the convex portion 112. FIG. 7: is a figure which shows the biometric data acquisition apparatus 300B of the 2nd modification of embodiment. The biometric data acquisition device 300B includes a biometric data acquisition sheet 100B and a transmitter 200.
　生体データ取得シート１００Ｂは、シート１１０Ｂ、一対の電極１２０、及び、一対の導電性面ファスナ１３０を有する。生体データ取得シート１００Ｂは、図１乃至図５に示すシート１１０の代わりにシート１１０Ｂを含む。 The biometric data acquisition sheet 100B has a sheet 110B, a pair of electrodes 120, and a pair of conductive surface fasteners 130. The biometric data acquisition sheet 100B includes a sheet 110B instead of the sheet 110 shown in FIGS.
　シート１１０Ｂは、図１乃至図５に示すシート１１０に対して、２つの開口部１１０Ａの中央に＋Ｚ方向側の表面から突出する凸部１１２を追加した構成を有する。このような凸部１１２は、導電性面ファスナ１３０と導電性面ファスナ２２０との位置ずれによる短絡を抑制するために設けられている。例えば、片方の導電性面ファスナ２２０が２つの導電性面ファスナ１３０を跨るように接続されると、２つの導電性面ファスナ１３０が短絡するおそれがある。このような短絡を抑制するために、凸部１１２を設けることにより、相対的な位置ずれによって片方の導電性面ファスナ２２０が２つの導電性面ファスナ１３０を跨ることが生じないようにしている。 The sheet 110B has a configuration in which a convex portion 112 protruding from the surface on the +Z direction side is added to the center of the two openings 110A with respect to the sheet 110 shown in FIGS. 1 to 5. Such a convex portion 112 is provided in order to suppress a short circuit due to a positional shift between the conductive surface fastener 130 and the conductive surface fastener 220. For example, if one conductive surface fastener 220 is connected so as to straddle the two conductive surface fasteners 130, the two conductive surface fasteners 130 may be short-circuited. In order to suppress such a short circuit, the convex portion 112 is provided so that the conductive surface fastener 220 on one side does not straddle the two conductive surface fasteners 130 due to the relative displacement.
　また、凸部１１２の代わりに、トランスミッタ２００の筐体２１１の－Ｚ方向側の表面に凸部を設けてもよい。また、生体データ取得シート１００とトランスミッタ２００に位置合わせ用の目印を設けてもよいし、トランスミッタ２００の筐体２１１の－Ｚ方向側の表面に、凸部１１２を挿入する凹部を設けてもよい。 Further, instead of the convex portion 112, a convex portion may be provided on the surface of the casing 211 of the transmitter 200 on the −Z direction side. Further, a mark for alignment may be provided on the biometric data acquisition sheet 100 and the transmitter 200, or a concave part for inserting the convex part 112 may be provided on the surface of the casing 211 of the transmitter 200 on the −Z direction side. ..
　また、２つの導電性面ファスナ１３０同士のＸ方向の間隔と、２つの導電性面ファスナ２２０同士のＸ方向の間隔を導電性面ファスナ１３０、２２０のＸ方向の幅よりも大きくすることによって、短絡が生じないような構成にしてもよい。 In addition, by making the distance between the two conductive surface fasteners 130 in the X direction and the distance between the two conductive surface fasteners 220 in the X direction larger than the width of the conductive surface fasteners 130, 220 in the X direction, You may make it a structure which does not generate a short circuit.
　図８は、実施の形態の第３変形例の生体データ取得シート１００Ｃを示す図である。生体データ取得シート１００Ｃは、図１に示す生体データ取得シート１００における両面テープ１３５の代わりに、糸１３５Ｃを用いて基部１３１と電極１２０を縫い合わせた構成を有する。 FIG. 8 is a diagram showing a biometric data acquisition sheet 100C according to a third modified example of the embodiment. The biometric data acquisition sheet 100C has a structure in which a thread 135C is used to sew the base 131 and the electrode 120 together instead of the double-sided tape 135 in the biometric data acquisition sheet 100 shown in FIG.
　糸１３５Ｃの縫い目は、開口部１１０Ａ及び１１１Ａの開口のすぐ内側で開口に沿って矩形状に設けられている。このため、糸１３５Ｃによって縫い合わされる領域を大きく取ることができ、導電性面ファスナ１３０の基部１３１と電極１２０の接合強度を高めることができる。 The seam of the thread 135C is provided in a rectangular shape along the opening just inside the openings of the openings 110A and 111A. For this reason, a large area to be sewn with the thread 135C can be taken, and the bonding strength between the base 131 of the conductive surface fastener 130 and the electrode 120 can be increased.
　なお、糸１３５Ｃは銀メッキが施されていても、施されていなくてもどちらでもよいが、銀メッキが施されている場合には、導電性面ファスナ１３０と電極１２０の電気的な接続をより信頼性が高い状態で実現することができる。上述のように、糸１３５Ｃで電極１２０と基部１３１を縫い合わせる形態よりも両面テープ１３５（図１乃至図３参照）で貼り合わせる方が製造が容易であるが、糸１３５Ｃで縫い合わせてもよい。 The thread 135C may be silver-plated or may not be silver-plated, but when silver-plated, the conductive surface fastener 130 and the electrode 120 are electrically connected. It can be realized in a more reliable state. As described above, it is easier to manufacture the electrodes 120 and the base 131 with the double-sided tape 135 (see FIGS. 1 to 3) than the form in which the electrodes 120 and the base 131 are sewn together with the threads 135C, but the threads 135C may be sewn together.
　以上、本発明の例示的な実施の形態の生体データ取得シート、及び、生体データ取得装置について説明したが、本発明は、具体的に開示された実施の形態に限定されるものではなく、特許請求の範囲から逸脱することなく、種々の変形や変更が可能である。 Although the biometric data acquisition sheet and the biometric data acquisition device according to the exemplary embodiments of the present invention have been described above, the present invention is not limited to the specifically disclosed embodiments, and patents Various modifications and changes can be made without departing from the scope of the claims.
　本国際出願は２０１９年１月１５日に出願した日本国特許出願２０１９－００４２５１号に基づく優先権を主張するものであり、日本国特許出願２０１９－００４２５１号の全内容を本国際出願に援用する。 This international application claims priority based on Japanese Patent Application 2019-004251 filed on January 15, 2019, and the entire contents of Japanese Patent Application 2019-004251 are incorporated into this International Application. ..
