PROBLEM TO BE SOLVED: To provide a stress detector detecting psychological stress during driving or the like of a driver by a device as accurate and small as possible.SOLUTION: Electrodes (1, 2) are fitted to two parts (F1, F2) of a measurement object respectively and a voltage inversely proportional to the biological resistance of both electrodes (1, 2) interconnected by a cord (3) is measured in a measurement part in a transmission part 5. The voltage is converted to a frequency signal further and transmitted. On the reception side, the received frequency signal is returned to a voltage signal and the analyzed result of a short-term index and a long-term index further is output from it. The analyzed result of the short-term index is executed in the serial circuit of a differential filter and a peak hold part. There are two cases: a power source (6) is loaded on the stress detector on the transmission side induced electromotive force from the stress detector on the reception side is the power source.COPYRIGHT: (C)2008,JPO&INPIT【課題】運転者の運転時等の精神的ストレスをできるだけ正確で且つ小型の装置で実現したストレス検出装置を提供する。【解決手段】測定対象者の2つの部位(F1, F2)にそれぞれ電極(1, 2)を嵌め、コード(3)で相互接続された両電極(1,2)の生体抵抗値に反比例した電圧を、送信部5中の測定部で測定する。この電圧をさらに周波数信号に変換して送信する。受信側では、受信した該周波数信号を電圧信号に戻し、これからさらに短期的指標及び長期的指標の解析結果を出力する。該短期的指標の解析結果は、微分フィルタとピークホールド部との直列回路で行う。送信側のストレス検出装置は電源(6)を搭載する場合と、受信側のストレス検出装置からの誘導起電力を電源とする場合がある。【選択図】図1
