Title:
PIEZOELECTRIC VIBRATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/039125
Kind Code:
A1
Abstract:
The present invention provides a piezoelectric vibration sensor having a high degree of freedom in the vibration detection direction, and that is suitable for achieving a low profile. The piezoelectric vibration sensor is provided with a piezoelectric ceramic oscillator comprising a frame-shaped piezoelectric ceramic plate with a first main surface, a second main surface, an outer side-surface, and an inner side-surface, a pair of primary electrodes disposed facing each other on the first main surface and second main surface of the piezoelectric ceramic plate, and a pair of second electrodes disposed facing each other on the outer side-surface and the inner side-surface of the piezoelectric ceramic plate; and a supporting body that supports the piezoelectric ceramic oscillator at four points.
