Abstract: An electromechanical energy converter for generating electric energy from mechanical vibrations has a bending bar, which is clamped at a fastening point to a holder that can be set in vibration and which can be elastically deflected at a free end area at a distance from the fastening point along a path curve from a neutral position transversely to the longitudinal extension of the bending bar relative to the fastening point. A deflectable point on the bending bar is connected to the mount via a deflectable bridge part extending along the bending bar for applying to the bending bar a mechanical prestress oriented substantially in the direction of longitudinal extension of the bending bar. A servo mechanism serves to set the prestress transferred from the bridge part to the bending bar. The bending bar has a drive connection to at least one electromechanical converter element for converting mechanical vibration energy into electric energy.
