Title:
PIEZOELECTRIC VIBRATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/027740
Kind Code:
A1
Abstract:
This piezoelectric vibration sensor is provided with a piezoelectric structural body that includes a piezoelectric element, which is disposed in a package, and vibrates corresponding to external vibration. The piezoelectric vibration sensor is provided with a buffer body, which absorbs and disperses an abutting force generated when the piezoelectric element vibrating due to the external vibration abuts to a stored material disposed in the package, said buffer body being provided at a position where a bend of the piezoelectric element is largest.
