Document Type and Number:
Japanese Patent JP5888486
Kind Code:
B2
Abstract:
A power generation unit includes: a deforming member adapted to deform while switching a deformation direction; a piezoelectric device provided to the deforming member, and having a pair of electrodes; a displacement sensor adapted to detect a deformation amount of the deforming member, and then output deformation amount information as information related to the deformation amount; an inductor electrically connected to the piezoelectric device; a switch disposed between the piezoelectric device and the inductor; and a switch control section adapted to control the switch so as to set the pair of electrodes to a shorted state for a predetermined period of time when the deformation amount exceeds a predetermined level.
