Power generating device, electronic apparatus, and transportation apparatus

摘要

A power generating device which includes a transformation member that is transformed by receiving a transformation force in a transformation direction, a first piezoelectric device that is disposed on the transformation member, a second piezoelectric device that is disposed on the transformation member, an inductor comprising a resonance circuit including the first piezoelectric device, a switch that is disposed in the resonance circuit, and a control unit that controls the switch to be in a conductive state for a predetermined period by detecting a voltage generated in the second piezoelectric device as the second piezoelectric device is transformed in response to the transformation force being applied to the transformation member.
