Abstract
There is provided a power generating element which is capable of converting vibration energy in various directions into electric energy without waste and less likely to be damaged even upon application of excessive vibration. Made available is a main generating structure (MGS) in which a first layer (100), a second layer (200) and a third layer (300) are laminated. The second layer (200) has a plate-like bridge portion (210), a central plate-like portion (220), a left-hand side plate-like portion (230) and a right-hand side plate-like portion (240), each of which is flexible, and the third layer (300), that is a weight body, formed in the “U” letter shape is joined with the lower surface thereof. The plate-like bridge portion (210) is protected by the weight body (300) circumference thereof. The first layer (100) is structured so that a piezoelectric material layer (105) is laminated on an upper surface of a lower layer electrode (E0), and four localized upper layer electrodes (E1 to E4) are laminated on the upper surface thereof. The base end of the plate-like bridge portion (210) is fixed to a pedestal (400). Vibration of the weight body (300) is efficiently transmitted to the pl…
