圧電素子およびそれを用いたデバイス
Document Type and Number:
Japanese Patent JP6580176
Kind Code:
B2
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.
