Abstract
A power generation apparatus includes a dielectric, a movable member being opposed to the dielectric with a predetermined distance, and an electret and an opposing electrode that are formed on the surface of the movable member facing the dielectric so as to generate a fringe electric field penetrating the dielectric between the two electrodes. When the volume occupancy of the dielectric between the electret and the opposing electrode varies in accordance with a displacement of the movable member, the power generation apparatus outputs the electric charge induced in the opposing electrode as electric current.
