Abstract
A power generator includes layered-polymer piezoelectric element that is arranged on an object to be a heat source and a vibration source, and that generates electric power according to vibration transmitted from the object; a first heat conductor containing a flexible material that is arranged on the object, and that conducts heat from the object. The power generator includes a second heat conductor that is arranged on the first heat conductor and the layered-polymer piezoelectric element, and that conducts heat from the first heat conductor. Furthermore, the power generator includes a thermoelectric element that is arranged on the second heat conductor so as to be layered on the second heat conductor on the layered-polymer piezoelectric element, and that generates electric power according to inner temperature difference between temperature on a heat absorbing side obtained by the second heat conductor and temperature on a heat releasing side.
