Abstract:
1. A power-generating apparatus comprising: a deformation member that is provided with a first piezoelectric device and deformed while switching a deformation direction; an amount of deformation detection unit that detects an amount of deformation of the deformation member; a pair of electrodes provided on the first piezoelectric device; a switch provided between the pair of electrodes; and a switch control unit that controls the switch to cause short-circuit between the pair of electrodes for a predetermined period when the amount of deformation is equal to or more than a predetermined amount, wherein the amount of deformation detection unit includes: a second piezoelectric device provided on the deformation member and used for detection of the amount of deformation; and a voltage detection unit that detects a voltage generated in the second piezoelectric device.
