Piezoelectric generator, pushbutton, radio module and method for producing a piezoelectric generator

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.
