| 摘要 |
The invention concerns a piezoelectric bistable generator comprising at least an elongated piezoelectric material element, and a mass thereto, characterised in that each end of said piezoelectric material element is fixed to a respective base and the mass is attached to piezoelectric material element in a position approximately centered on the element, said at least an piezoelectric material element being suited to bend so that it can assume two distinct stable equilibrium positions on the side of a central instable position in which it is disposed perpendicularly to the bases, whereby the piezoelectric material element is suitable to perform nonlinear bistable oscillations when the generator is subjected to displacements, the kinetic energy of such bistable oscillations being converted into electric energy and transformed by an electronic circuit in a suitable form for the powering of electric and/or electronic devices.
