Abstract
Description
本発明は、日常的に電気的な生体信号を取得するために用いられる衣服型のウェアラブルデバイスに関するものである。 The present invention relates to a clothes-type wearable device that is used to acquire electrical biological signals on a daily basis.
スポーツ選手にとっては、試合での結果を出すこともさることながら、トレーニングを行うことが日常的な行為となっている。したがって、競技力の向上や選手の体調管理のため、試合やトレーニングにおいて、選手のワークロード（運動負荷）を適切に管理し、設定することが重要となる。ワークロードを適切に管理、設定するにあたって、ＲＰＥ（Rate of Perceived Exertion：主観的運動強度）単位に時間をかけた値を用いることが一般的である（非特許文献１参照）。 For athletes, training is a daily activity, as well as providing results in matches. Therefore, it is important to appropriately manage and set a player's workload (exercise load) in a game or training in order to improve the competitive ability and manage the physical condition of the player. In order to appropriately manage and set a workload, it is common to use a value obtained by multiplying time by a RPE (Rate of Perforated Exercise) unit (see Non-Patent Document 1).
しかし、ＲＰＥを用いる方法はワークロードの大まかな目安を提供するものなので、ワークロードの推定精度を高める方法として、選手の心拍数から、ワークロードを推定する方法が提案されている（非特許文献２、非特許文献３参照）。
非特許文献２、非特許文献３に開示された方法で選手の正確なワークロードを推定するには、正確な心拍数を、選手の負担にならないように随時計測する手段が必要である。
However, since the method using the RPE provides a rough guideline of the workload, a method for estimating the workload from the heart rate of the athlete has been proposed as a method for improving the estimation accuracy of the workload (non-patent document). 2, Non-Patent Document 3).
In order to estimate an accurate workload of a player by the methods disclosed in Non-Patent Document 2 and Non-Patent Document 3, means for measuring an accurate heart rate as needed so as not to be a burden on the player is necessary.
従来、心拍数を計測する方法としては、光学式の脈波センサを備えた装置を選手の腕などに装着し、脈波センサを用いて心拍数を計測する方法がある。しかしながら、脈波センサは例えば選手の動きに起因するノイズの影響を受け易いため、選手の運動時における脈波を精度良く計測することが難しいという問題点があった。 Conventionally, as a method of measuring a heart rate, there is a method of mounting a device provided with an optical pulse wave sensor on a player's arm or the like and measuring the heart rate using a pulse wave sensor. However, since the pulse wave sensor is easily influenced by noise caused by, for example, the movement of the player, there is a problem that it is difficult to accurately measure the pulse wave during the exercise of the player.
また、別の方法として、生体信号（心電波形）を収集するための電極を、選手が着用するバンドや衣服に取り付けたウェアラブルデバイスを用いて選手の心電波形を計測し、この心電波形から心拍数を求める方法がある。
しかしながら、バンド型のウェアラブルデバイスの場合、選手がウェアラブルデバイスを装着していることを意識してしまい、運動に集中しづらいという問題点があった。
As another method, the electrocardiographic waveform of a player is measured using a wearable device in which electrodes for collecting biological signals (electrocardiographic waveform) are attached to a band or clothing worn by the player. There is a method to calculate the heart rate from.
However, in the case of the band-type wearable device, there is a problem that the player is aware that the wearable device is worn, and it is difficult to concentrate on exercise.
一方、発明者らは、人体への装着感をより軽減することができる衣服型のウェアラブルデバイスを提案した（例えば非特許文献４参照）。衣服型のウェアラブルデバイスでは、人体への密着性および柔軟性に優れた素材を衣服として用いることで、快適性を実現しつつ、長時間、かつ運動時でも選手の心電波形を計測することが可能になる。 On the other hand, the inventors proposed a wearable device of a clothes type capable of further reducing the feeling of wearing on the human body (see, for example, Non-Patent Document 4). Clothing-type wearable devices can measure the electrocardiographic waveform of athletes even during exercise for long periods of time while realizing comfort by using materials with excellent adhesion and flexibility to the human body as clothing. It will be possible.
衣服型のウェアラブルデバイスの場合、取得した心電波形を外部に送信する端末と電極との間を配線によって電気的に接続している。心電波形を適切に取得するため、配線には、（I）信号伝送のための適切な導電性を有すること、（II）電極以外の部分で検出された信号が電極で取得した信号に混入したり、複数の電極間が短絡したりすることを避けるため、配線と外部との電気的絶縁性・防水性が確保されていること、が必要となる。 In the case of a wearable wearable device, the terminal that transmits the acquired electrocardiogram waveform to the outside and the electrode are electrically connected by a wire. In order to properly acquire an electrocardiogram waveform, the wiring has (I) appropriate conductivity for signal transmission, (II) a signal detected in a portion other than the electrode is mixed in the signal acquired by the electrode In order to prevent short circuiting between a plurality of electrodes, and electrical insulation between the wiring and the outside, it is necessary to ensure waterproofness.
従来の衣服型のウェアラブルデバイスでは、上記の（I）、（II）の条件を満たすため、導電体からなる配線を、絶縁体（例えば防水テープ）で覆うようにしていた。配線と防水テープとは、電極と端末との間の最短経路を取るように配置されている。また、衣服の美観を損ねることを避けるため、配線と防水テープとは衣服の内側に配置されている。
しかしながら、従来の衣服型のウェアラブルデバイスでは、衣服の内側にある配線と防水テープとが人体に接触することによって人が不快感を感じる可能性があり、更なる改善が求められていた。
In conventional clothes-type wearable devices, in order to satisfy the above conditions (I) and (II), wiring made of a conductor is covered with an insulator (for example, waterproof tape). The wiring and the waterproof tape are arranged to take the shortest path between the electrode and the terminal. Also, in order to avoid damaging the appearance of the clothes, the wiring and the waterproof tape are disposed inside the clothes.
However, in the conventional wear type wearable device, there is a possibility that a person may feel discomfort when the wiring and the waterproof tape inside the clothes come in contact with the human body, and further improvement has been desired.
本発明は、上記課題を解決するためになされたもので、着用時の不快感を軽減することができる衣服型のウェアラブルデバイスを提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a wearable device of a clothes type that can reduce discomfort when worn.

衣服１の素材は通常の衣料品で用いられる綿、羊毛等の天然繊維素材、ポリエステル、ナイロン等の合成繊維素材を何ら制限なく用いることができるが、本発明はかかる衣服１の素材に限定されるものではない。
FIG. 2A is a view of the ventral side of the clothes 1 as viewed from the human body side, and FIG. 2B is a view of the back side of the clothes 1 as viewed from the human body side.
The material of the garment 1 may be natural fiber materials such as cotton and wool used in ordinary clothing, and synthetic fiber materials such as polyester and nylon without limitation, but the present invention is limited to the material of the garment 1 It is not a thing.
電極２を構成する導電体は、特に限定されないが、銀、銅、金、ステンレス等の金属を細線に加工して柔軟性を付与し、布帛として構成したものや、上記金属を繊維素材にメッキしたもの、あるいはカーボンファイバーや導電性高分子を繊維素材に含浸したものなどを用いることができる。特に、導電性高分子としてポリ３、４−エチレンジオキシチオフェン（ＰＥＤＯＴ）にポリスチレンスルホン酸（ポリ４−スチレンサルフォネート；ＰＳＳ）をドープしたＰＥＤＯＴ／ＰＳＳを用い、この導電性高分子を繊維素材に含浸したものは、安全性、加工性の観点から電極として特に好適である。 The conductor that constitutes the electrode 2 is not particularly limited, but a metal such as silver, copper, gold, and stainless steel is processed into a thin wire to give flexibility, and is configured as a fabric, or the metal is plated on a fiber material. Or a fiber material impregnated with carbon fiber or conductive polymer can be used. In particular, PEDOT / PSS doped with polystyrenesulfonic acid (poly-4-styrene sulfonate; PSS) in poly 3,4-ethylenedioxythiophene (PEDOT) is used as the conductive polymer, and the conductive polymer is used as a fiber. The material impregnated with the material is particularly suitable as an electrode from the viewpoint of safety and processability.
図１、図２（Ａ）、図２（Ｂ）に示すように、電極２は、衣服１の着用者（人体）の右の腋窩部と右の側胸部と右の下肋部とのうち少なくとも１つの部位の皮膚と接触し得るように衣服１の裏面（着用者の皮膚と接触する面）に固定されている。同様に、電極３は、衣服１の着用者の左の腋窩部と左の側胸部と左の下肋部とのうち少なくとも１つの部位の皮膚と接触し得るように衣服１の裏面に固定されている。 As shown in FIG. 1, FIG. 2 (A), FIG. 2 (B), the electrode 2 is composed of a right axillary part, a right side chest part, and a right lower arm part of the wearer (human body) of the clothes 1 It is being fixed to the back surface (surface which contacts a wearer's skin) of the clothes 1 so that the skin of at least 1 site | part can contact. Similarly, the electrode 3 is fixed to the back surface of the garment 1 so as to be in contact with the skin of at least one of the left axilla, left side chest, and left lower groin of the wearer of the garment 1. ing.
なお、腋窩部はいわゆる脇の下の領域を意味し、側胸部は腋窩部よりも下方の領域を意味し、下肋部は側胸部よりも更に下方の領域を意味する。人体の各部の名称については、例えば参考文献「橋本 尚詞，“看護学入門 １ 人体のしくみと働き”，ｐｐ．３−８，２０１３年」に開示されている。 The axillary region means the so-called armpit region, the side chest means the region below the axillary portion, and the lower eyelid means the region further below the side chest. The names of each part of the human body are disclosed, for example, in the reference document "Shinji Hashimoto," Introduction to Nursing Science 1 Structure and Function of Human Body, "pp. 3-8, 2013.
電極２，３の衣服１への固定方法としては、例えば電極２，３を衣服１に縫い付ける方法、電極２，３を衣服１に接着する方法、電極２，３を衣服１に含浸させる方法などがある。 As a method for fixing the electrodes 2 and 3 to the garment 1, for example, a method of sewing the electrodes 2 and 3 to the garment 1, a method of bonding the electrodes 2 and 3 to the garment 1, and a method of impregnating the garment 1 with the electrodes 2 and 3 and so on.
従来の衣服型のウェアラブルデバイスでは、電極を胸部に固定していた。しかしながら、電極を胸部に固定した場合、胸部筋肉が発達した着用者の場合に筋電を拾ってしまう可能性や、胸部の動きによるノイズを拾ってしまう可能性があり、心電波形の正確な計測ができない場合があった。 In conventional clothes-type wearable devices, the electrodes are fixed to the chest. However, when the electrode is fixed to the chest, there is a possibility of picking up myoelectricity in the case of a wearer who has developed chest muscles, or picking up noise due to movement of the chest. There were cases where measurement could not be made.
そこで、本実施例では、腋窩部と側胸部と下肋部とのうち少なくとも１つの部位の皮膚と接触し得るように電極２，３を衣服１の裏面に固定することにより、着用者の筋肉の発達度合いや体形の違いによる影響を受け難くなり、電極２，３と着用者の皮膚との密着性を向上させることができる。その結果、本実施例では、長時間、かつ運動時でも着用者の心電波形を安定的に取得することが可能となる。 Therefore, in this embodiment, the electrodes 2 and 3 are fixed to the back surface of the garment 1 so as to be in contact with the skin of at least one of the axilla, the side chest, and the lower buttocks. Can be less affected by the degree of development and the difference in body shape, and the adhesion between the electrodes 2 and 3 and the skin of the wearer can be improved. As a result, in the present embodiment, it is possible to stably acquire the wearer's electrocardiographic waveform for a long time and during exercise.
配線５，６は、電極２，３とコネクタ４とを電気的に接続する。配線５，６としては、衣服１の裏面に導電性高分子を印刷したものや、衣服１の裏面に導電性樹脂のフィルムを貼り付けたもの、衣服１の裏面に導電性繊維構造物を縫い付けたもの、衣服１の裏面に導電性繊維構造物を接着したもの等を用いることができる。 The wires 5 and 6 electrically connect the electrodes 2 and 3 to the connector 4. As the wirings 5 and 6, a conductive polymer printed on the back of the garment 1, a conductive resin film pasted on the back of the garment 1, and a conductive fiber structure is sewn on the back of the garment 1. Attached ones, those obtained by bonding a conductive fiber structure to the back surface of the garment 1, etc. can be used.
コネクタ４は、電極２，３と生体信号取得端末１０とを接続するための機能部である。コネクタ４は、生体信号取得端末１０と接続する部分が、人体と接触する面と反対側の面に露出するように衣服１に実装されている。コネクタ４は、縫製や接着材等によって衣服１に固定されている。なお、本実施例では、コネクタ４が衣服１の胸側（前身頃）と背側（後ろ身頃）に１つずつ設けられている。このようにコネクタ４を２つ設けている理由は、着用者にとって都合の良い側に生体信号取得端末１０を装着できるようにするためである。 The connector 4 is a functional unit for connecting the electrodes 2 and 3 and the biological signal acquisition terminal 10. The connector 4 is mounted on the clothes 1 such that a portion connected to the biological signal acquisition terminal 10 is exposed on the side opposite to the side in contact with the human body. The connector 4 is fixed to the clothes 1 by sewing, an adhesive or the like. In the present embodiment, one connector 4 is provided on the chest side (front body) and the back side (back body) of the clothes 1. The reason for providing two connectors 4 in this manner is to enable the biological signal acquisition terminal 10 to be attached to the side convenient for the wearer.
生体信号取得端末１０の筐体表面には、コネクタ４と嵌合するように配置されたコネクタ（不図示）が設けられている。衣服１におけるコネクタ４の露出部分と生体信号取得端末１０に設けられたコネクタとを嵌合させることにより、生体信号取得端末１０が衣服１に機械的に固定される同時に、電極２，３と生体信号取得端末１０とが、コネクタ４および配線５，６を介して電気的に接続される。

It is arranged to take a route to the back connector 4.
さらに、本実施例では、配線５，６の進行方向に対して直角な方向の絶縁部材８，９の幅を、衣服１の縫い目の幅程度とし、人体と絶縁部材８，９との接触面積を小さくすることで、ウェアラブルデバイスの着用時の不快感をさらに軽減することができる。また、絶縁性を確保するため、配線５，６の進行方向に対して直角な方向の絶縁部材８，９の幅を、少なくとも配線５，６の高さの２倍と配線５，６の幅との和よりも大きくする。 Furthermore, in the present embodiment, the width of the insulating members 8 and 9 in the direction perpendicular to the traveling direction of the wires 5 and 6 is about the width of the seam of the garment 1 and the contact area between the human body and the insulating members 8 and 9 By making the size of the wearable device smaller, it is possible to further reduce the discomfort when wearing the wearable device. Further, in order to ensure insulation, the width of the insulating members 8 and 9 in the direction perpendicular to the traveling direction of the wirings 5 and 6 is at least twice the height of the wirings 5 and 6 and the width of the wirings 5 and 6 Make it larger than the sum of
絶縁部材８，９としては、例えばフッ素樹脂、ポリウレタン、ポリエステル、ナイロン等の樹脂からなるフィルム状の基材の片面にホットメルト等の接着材層を積層した防水テープが好適である。この絶縁部材８，９を、上記のとおり配線５，６の、人体に接触する面を被覆するように設ける。なお、防水テープからなる絶縁部材８，９を用いて、配線５，６の衣服１への固定と絶縁被覆とを同時に達成してもよい。 As the insulating members 8 and 9, for example, a waterproof tape in which an adhesive material layer such as a hot melt is laminated on one side of a film-like substrate made of a resin such as fluorocarbon resin, polyurethane, polyester or nylon is preferable. As described above, the insulating members 8 and 9 are provided so as to cover the surfaces of the wirings 5 and 6 that come into contact with the human body. Note that the insulating members 8 and 9 made of waterproof tape may be used to simultaneously fix the wires 5 and 6 to the clothing 1 and the insulating coating.
また、コネクタ４が衣服１を貫通して裏面に露出するタイプの場合には、人体と接触する裏面に露出したコネクタ４についても絶縁部材７で覆う必要がある。絶縁部材７としては、絶縁部材８，９と同様に例えば防水テープを用いることができる。ただし、着用者の不快感を軽減するため、絶縁部材７はなるべく小さいことが望ましい。 Moreover, in the case of the type in which the connector 4 penetrates the clothes 1 and is exposed on the back surface, the connector 4 exposed on the back surface in contact with the human body also needs to be covered with the insulating member 7. As the insulating member 7, for example, a waterproof tape can be used similarly to the insulating members 8 and 9.
