Title: PIEZO-BASED ENERGY TRANSDUCER
Abstract:
The invention relates to an energy transducer which converts two-dimensional mechanical, particularly vibrational and/or impact energy into electrical energy using the piezoelectric effect. To this end, the energy transducer (2) is provided with a seismic mass (3) so that the shear deformation of the piezo-component (4) of the energy transducer is able to be exploited as a result of the angle between the movement vector (6, 6') of the seismic mass and the vector of the remanent polarisation (5) of the piezo-component.
