Title:
PIEZOELECTRIC ELEMENT AND DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/175321
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fibrous piezoelectric element which enables a large electric signal to be drawn out by stress produced by relatively small deformation.
A piezoelectric element includes a braid composed of a conductive fiber and a piezoelectric fiber. In the braid, the conductive fiber is a core, and the piezoelectrsic fiber is a covering fiber that covers the periphery of the conductive fiber.
