ABSTRACT:
A bending transducer device for generating electrical energy from deformations, and a circuit module which has such a bending transducer. The bending transducer includes at least one electrically deformable, vibration-capable, electrically conductive support structure, one piezoelectric element and a first contacting element, the conductive support structure having a first restraining area and a second restraining area for restraining the support structure, the piezoelectric element being designed and situated on the support structure in such a way that the piezoelectric element is deformable due to the deformation of the support structure caused by vibrations, and a first electrode for picking up the voltage generated by the deformation of the piezoelectric element is formed and contacted by the support structure, the first contacting element being connected electrically conductively to the support structure outside the first restraining area and the second restraining area.
