PROBLEM TO BE SOLVED: To eliminate the need for a lead wire etc. for sending measurement data from a sensor to a transmitter, and to unnecessitate to provide a battery on a circuit of a sensor etc.SOLUTION: On a flexible sheet which can be deformed freely along the surface of the skin, a myoelectric sensor, a signal processing part, a wireless tag (RFID) communication part and an antenna coil are arranged. Thus, even if shape change occurs at a site of an electrode for lead-through with expansion/contraction of a muscle, the sheet is deformed according to the shape change to allow the electrode to closely adhere to the surface of the skin, so that an artificial hand etc. are controlled while closely adhering to the surface of the skin of a user (operator), resulting in improving measuring sensitivity of the myoelectric signal. Through the RFID communication part, measuring data of the myoelectric signal are transmitted in real time, and power can be received from outside simultaneously. Thus, power can be supplied to the myoelectric sensor, the signal processing part and the wireless tag (RFID) communication part, so that a battery device is not necessitated inside of a sensor signal interface device.COPYRIGHT: (C)2007,JPO&INPIT【課題】センサからの計測データを送信機に送るためのリード線等を不要にすること及びセンサ等の回路にバッテリーを設けることを不要とすること。【解決手段】本発明は、皮膚表面に沿って自在に変形し得る柔軟性を有するシート上に、筋電センサと信号処理部と無線タグ(RFID)通信部とアンテナコイルを設けることによって、筋肉の膨張・収縮に伴って導出用電極の部位に形状変化が生じた場合でも、この形状変化に応じてシートが変形し、導出用電極は皮膚表面に密着させ、使用者(操作者)の皮膚表面と密着して義手等を制御できることとなり、筋電位信号の計測感度が向上する。また、RFID通信部を介して、筋電位信号の計測データをリアルタイムに送信すると同時に、外部から電力を受信できるため、筋電センサと信号処理部とRFID通信部に給電することが可能となり、センサ信号インターフェース装置内部にバッテリー装置を不要とする。【選択図】図1
