PROBLEM TO BE SOLVED: To provide a bioelectric signal acquisition system using wearable electrodes capable of precisely detecting the R wave etc. of electro-cardiographic waveform over a long term.SOLUTION: A bioelectric signal acquisition system acquires bioelectric signals from electrodes which are installed at predetermined positions of a garment and detect the bioelectric signals of a living body when contacting with the living body wearing the garment. The system comprises an acceleration sensor which detects variation in the posture of the living body; an acquisition part which acquires the bioelectric signals by using a first electrode and plural second electrodes different from the first electrode; and a switch which selects one of the bioelectric signals acquired by using the first electrode and the second electrodes, when the acceleration sensor detects the variation in the posture of the living body.SELECTED DRAWING: Figure 9 【課題】心電波形のＲ波等の生体電気信号を長期間にわたって精度よく検出することが可能なウェラブル電極を用いた生体電気信号取得システムを提供する。【解決手段】本願発明は、衣服の所定の位置に設置され、衣服を身に着けた生体に接触した際に生体の生体電気信号を検出する電極から生体電気信号を取得する生体電気信号取得システムであり、生体の姿勢の変化を検知する加速度センサと、第１の電極および第１の電極とは異なる複数の第２の電極を用いて生体電気信号を取得する取得部と、加速度センサが生体の姿勢の変化を検知した際に、第１の電極と複数の第２の電極のいずれかを用いて取得された生体電気信号のうち、１つの生体電気信号を選択するスイッチとを備える。【選択図】 図９
