ABSTRACT:
A circuit module, e.g., for use in a vehicle tire, includes a housing, a piezoelectric generator, which has a mass element that is movable within the housing and a spring device, which has at least one piezoelectric element, the mass element and the spring device forming an oscillatory system, and the piezoelectric element being elastically deformable in response to the oscillation of the oscillatory system. A current supply circuit is provided for receiving a piezoelectric voltage output by the piezoelectric element in response to the mechanical deformation thereof and for supplying power to the circuit module.
