Device for producing electrical energy from vibrations of surface area for self-energizing system, particularly self-energizing sensor system, has individual piezoelectric element, which has upper side and lower side

摘要

The device has an individual piezoelectric element (4), which has an upper side and a lower side. The piezoelectric element guides an elongation or buckling between the upper side and the lower side for producing an electric voltage between the upper side and the lower side. The lower side is formed for mechanical coupling with the surface area (2), and the upper side is mechanically connected with a mass element (7).
