ELECTROMECHANICAL ENERGY STORE, IN PARTICULAR FOR INTEGRATED CIRCUITS
The invention relates to an energy store for an electric circuit, in particular for an integrated circuit, comprising a piezoelectric element (2) consisting of a piezoelectric material between two electrodes. The energy store further comprises a mechanical storage element (1) which is designed and arranged such that, when an electric voltage is applied to the piezoelectric element (2), the mechanical storage element (1) is elastically deformed. Such an energy store has a higher energy density than a purely capacitive energy store and is therefore easier to integrate into integrated circuits.
