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, a displacement detection section adapted to detect that the deforming member is displaced beyond a predetermined level, an inductor electrically connected to the piezoelectric device, a switch disposed between the piezoelectric device and the inductor, and a control section adapted to set the piezoelectric device and the inductor to an electrically conductive state via the switch if the displacement detection section detects that the deforming member is displaced beyond the predetermined level.
