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.
