PIEZOELECTRIC ENERGY CONVERTER FOR CONVERTING MECHANICAL ENERGY INTO ELECTRICAL ENERGY BY MEANS OF A FLUID FLOW, METHOD FOR CONVERTING MECHANICAL ENERGY INTO ELECTRICAL ENERGY BY USING THE ENERGY CONVERTER AND USING THE METHOD

摘要

The invention relates to a piezoelectric energy converter (1) for converting mechanical energy into electrical energy with at least one piezoelectric element (2), into which mechanical force generated by a fluid flow (3) can be coupled in such a manner that the piezoelectric element is excited into vibration. The invention further relates to the corresponding method. Mechanical force is coupled into the piezo element by means of the vibrations. Electrical energy is obtained by exploiting piezoelectric effects. The piezoelectric energy converter is used especially in MEMS (Micro Electro Mechanical Systems) technology. The device and the method can be used in connection with autonomous power supply systems, for example, in tire sensor systems.
