Document Type and Number:
WIPO Patent Application WO/2019/137037
Kind Code:
A1
Abstract:
Disclosed is a wideband energy harvesting device based on mechanical induction, comprising: a base, and an energy harvesting mechanism and a mechanical induction mechanism located in the base, wherein the energy harvesting mechanism comprises a cantilever beam, a piezoelectric wafer is adhered to an upper surface of one side of the cantilever beam close to a fixing end thereof, an upper surface of the piezoelectric wafer is fixedly connected to a positive electrode lead in a conducting manner, and a lower surface of one end of the cantilever beam close to the fixing end thereof is fixedly connected to a negative electrode lead in a conducting manner; and the mechanical induction mechanism comprises an upper spring-damping mechanism and a lower spring-damping mechanism symmetrically provided on two sides of a free end of the cantilever beam, the axis of both being perpendicular to the lengthwise direction of the cantilever beam, and one end of each of the upper spring-damping mechanism and the lower spring-damping mechanism away from the cantilever beam being fixedly connected to an inner wall of the base.
