<P>PROBLEM TO BE SOLVED: To provide a power generating device, and the like, which can adjust resonance frequency to generate a large amount of power with a small-scale circuit. <P>SOLUTION: A power generating device includes: a deformable member 104 that is deformed in switched directions; first piezoelectric elements (108, 109a, and 109b) that are provided in the deformable member 104; displacement detection means 140 that generates displacement information as information on displacement due to deformation of the deformable member 104; adjusting-piezoelectric elements (114, 115a, and 115b) that are provided in the deformable member 104; resonance frequency adjustment means 119 that adjusts resonance frequency of the deformable member 104 on the basis of a control signal; an inductor L that forms a resonance circuit including the first piezoelectric elements (108, 109a, and 109b); a switch SW provided in the resonance circuit; and control means 112 that, on the basis of the displacement information, generates the control signal and puts the switch SW in a conduction state for a predetermined period of time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
