In an exemplary embodiment, a vibration waveform sensor includes a pair of conductive pads, and a piezoelectric elementwhose terminal electrodes are connected thereto, which are provided on a board, and these are surrounded by a conductive ring-like spacer. On the interior side of the spacer, a cover partsubstantially like a disk is provided in a manner covering over the pair of conductive padsand the piezoelectric element. The cover partcuts off any humming noise from the top face of the piezoelectric elementover a continuous surface, which results in a reduction of humming noise.

Vibration waveform sensor and pulse wave detection device

In an embodiment, a sensor moduleincludes a piezoelectric elementplaced on the principal face of a board, which piezoelectric element is surrounded by a vibration ringand installed in an appropriate position on a person's arm, neck, etc., using a medical fixing tape, etc., with the vibration ringcontacting the person's skin. When a pulse wave is transmitted to the vibration ringfrom the skin, the boardalso vibrates and this vibration is transmitted to the piezoelectric element. Then, the piezoelectric elementis displaced and the pulse wave vibration is converted to an electrical signal. The resulting electrical signal is amplified by an amplifier on the boardand input to the vibration analysis device, where prescribed calculations are run to perform waveform analysis. The vascular state, etc., can be known from pulse waveforms.
