PIEZOELECTRIC POWER GENERATION DEVICE

WIPO Patent Application WO/2017/104530

A1

Provided is a piezoelectric power generation device which has high power generation efficiency, for which it is possible to know the compression end time, and for which a piezoelectric body is not easily damaged. This piezoelectric power generation device 1 is equipped with: piezoelectric power generation element 3 wherein a plate-like piezoelectric element 10 is provided on one surface of a metal plate 2; and multiple support members supporting the piezoelectric power generation element 3. At least one of the multiple support members has a reversing spring 8. The reversing spring 8 has a shape recovery property, and is provided so as to undergo reversal due to the pressing load required for the piezoelectric power generation element 3 to generate power.
