摘要
PURPOSE: By comparing to the cantilever structure of being general and a lot multiplying the effective area the high efficiency piezoelectricity energy harvest time having spiral structure a lot improves the energy conversion efficiency.;CONSTITUTION: A substrate(201) is proceed the elastic role. In order to draw out the energy it electrical, the first electrode(202) is evaporated in substrate. The piezoelectric element(203) is evaporated in the first electrode. The piezoelectric element changes the mechanical energy into the energy it electrical. The piezoelectric element has the spiral structure. The piezoelectric element has the outer vibrator and the natural frequency canning be resonated. The second electrode(204) is evaporated in the piezoelectric element in order to draw out the energy it electrical as described above.;COPYRIGHT KIPO 2010
