Abstract: A piezoelectric generator is specified, comprising a deformation body, which spans a projection surface and is embodied with a setpoint pressure surface situated opposite the projection surface, wherein the projection surface can be converted from a smaller projection surface when not loaded under pressure into a larger projection surface when pressure is applied to the setpoint pressure surface substantially perpendicular to the projection surface, and a spring effect is provided which counteracts an application of pressure to the setpoint pressure surface, wherein an electromechanical transducer element comprising a piezoelectric material wholly or partly spans the projection surface, such that the transducer element is embodied in an expandable fashion upon pressure being applied to the deformation body, and electrical microenergy can be generated by means of the piezoelectric material.

Abstract: An electrostatic microgenerator having electret films which are arranged above one another in a double layer and each have a metal layer arranged on one side thereof as an electrode. The films are embedded in a hermetically sealed casing in a loosely wound manner. Applying pressure to a first desired pressure surface, which is provided on the outside parallel to the capacitor plates formed in this manner, makes it possible to generate an electrical voltage by changing the distance between the capacitor plates.

Abstract: A piezoelectric generator (1) is specified, comprising a deformation body (5), which spans a projection surface (6) and is embodied with a setpoint pressure surface (8) situated opposite the projection surface (6), wherein the projection surface (6) can be converted from a smaller projection surface (6) when not loaded under pressure into a larger projection surface (7) when pressure is applied to the setpoint pressure surface (8) substantially perpendicular to the projection surface (6), and a spring effect is provided which counteracts an application of pressure to the setpoint pressure surface (8), wherein an electromechanical transducer element comprising a piezoelectric material wholly or partly spans the projection surface (6), such that the transducer element is embodied in an expandable fashion upon pressure being applied to the deformation body (5), and electrical microenergy can be generated by means of the piezoelectric material.
