Abstract
A power generating device includes: a piezoelectric member that is formed from a piezoelectric material; one pair of electrodes that are installed to the piezoelectric member; a transformation unit that repeatedly transforms the piezoelectric member; an inductor that is installed between the one pair of electrodes and configures a resonance circuit together with a capacitive component of the piezoelectric member; a switch that is connected to the inductor in series; and a switch control unit that connects the switch when a transformation direction of the piezoelectric member is switched, and cuts off the switch when a time corresponding to a half period of a resonance period of the resonance circuit elapses.
