ABSTRACT:
An array-type capacitive pressure pulse wave sensor includes m rows of lower electrodes arranged in parallel with each other to extend substantially linearly in a direction approximately orthogonal to the extending direction of the artery at the time of measurement, n columns of upper electrodes arranged in parallel with each other at a prescribed distance from the m lower electrodes to extend in a direction crossing the extending direction of the m lower electrodes, and m×n capacitive elements formed at intersections of the m lower electrodes and the n upper electrodes. The m×n capacitive elements are arranged in a staggered manner when the pressure detecting portion is seen in two dimensions. Thus, it is possible to provide an array-type capacitive pressure pulse wave sensor that can be manufactured inexpensively and that ensures accurate and stable measurement of the pressure pulse wave.
