    • 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.
    • 阵列型电容式压力脉搏波传感器包括相互平行布置的m列下电极,以在测量时与动脉的延伸方向大致正交的方向基本上线性地延伸,上列电极排列成n列 在与m个下部电极的规定距离处彼此平行,并且在与m个下部电极的延伸方向交叉的方向上延伸,以及在m个下部电极和n个上部电极的交叉处形成的电容元件。 当在两个维度上看到压力检测部分时,mxn电容元件以交错的方式布置。 因此,能够提供廉价制造的阵列型电容式压力脉搏波传感器,能够确保压力脉搏波的精确,稳定的测量。
