Abstract

The invention relates to a monostable piezoelectric, inductive or capacitive generator with large area of stability. At least one element of piezoelectric material, magnetic material within a coil, or conductive material to form the plates of a capacitor is able to oscillate around a large position of equilibrium, said at least one element being subjected to monostable nonlinear oscillations. The kinetic energy of nonlinear oscillations is converted into electrical energy and collected and exploited by a proper electronic circuit for powering electronic and/or electric devices. The invention also relates to multistable nonlinear generators of electricity.
