ABSTRACT:
A pulse wave detecting apparatus including a pulse wave sensor having a press surface and including at least one array of pressure sensing elements provided in the press surface; a pressing device which produces a pressing force to press the press surface of the pulse wave sensor against an arterial vessel via body surface; a regulating device for changing the pressing force of the pressing device applied to the pulse wave sensor, determining an optimum value of the pressing force based on at least one of the pulse wave signals generated from the pressure sensing elements, and holding the pressing force of the pressing device at the thus determined optimum value; a lower-peak variation determining device for determining a lower peak of at least one pulse of each of the pulse waves represented by the respective pulse wave signals from the pressure sensing elements, the lower-peak variation determining device iteratively determining a variation of the respective lower peaks of the pulse waves with respect to the array of pressure sensing elements after the pressing force of the pressing device is held at the optimum value; and a judging device for judging whether a pressing condition of the pulse wave sensor on the body surface is stable, based on change of the lower-peak variations determined by the lower-peak variation determining device.
