1. An apparatus for conversion of mechanical energy to electrical energy, the apparatus comprising:
- a mass which can oscillate;
a transmission element for transmission of oscillations;
an elastic element;
an electrovolumetric transducer element arranged to be prestressed in compression by the elastic element, and wherein the elastic element is adapted to continuously stress the electrovolumetric transducer element even during oscillation of said mass;
wherein the electrovolumetric transducer element is in engagement with the transmission element such that any oscillation of the mass is transformed at least partially to a change in the volume of the electrovolumetric transducer element, producing an electrical voltage.

Abstract
An apparatus for conversion of mechanical energy to electrical energy having a piezo transducer (1), which is formed from two or more layers, and having a mass/spring system (2, 3, 4), which can oscillate, in a holder (5), which is caused (6) to oscillate mechanically when stimulated, which oscillations periodically deform the piezo transducer such that an alternating voltage occurs on the connecting wires (7) of the transducer.
