ABSTRACT:
A pulse wave detecting apparatus having a pressure-sensitive semiconductor element for detecting pulsation of an artery of a subject and converting the detected pulsation into electrical signal, the electrical signal representing pulse wave corresponding to the pulsation, the semiconductor element being pressed against a body surface of the subject such that the semiconductor element is aligned with the artery via the body surface, the apparatus including a timer device for measuring operation time of the pressure-sensitive semiconductor element, and generating a full-use signal when the measured operation time exceeds a reference value representing that the semiconductor element has been fully operated up to its permitted operation time.
