POWER GENERATION UNIT, ELECTRONIC APPARATUS, TRANSPORTATION DEVICE, AND METHOD OF CONTROLLING POWER GENERATION UNIT

摘要

A power generation unit includes a deforming member (a beam) adapted to deform while switching a deformation direction, a first piezoelectric device provided to the deforming member (the beam), a second piezoelectric device provided to the deforming member (the beam), an inductor electrically connected to the first piezoelectric device, a switch disposed between the first piezoelectric device and the inductor, and a control section adapted to detect a voltage generated in the second piezoelectric device, and if the voltage detected has a level one of equal to and higher than a predetermined level, electrically connect the first piezoelectric device and the inductor to each other using the switch.
