Abstract

An apparatus for supplying power, for example, to a sensor, has a passive piezoelectric transducer that can be deformed by a mechanical energy storage device. The transducer supplies a corresponding electrical voltage to operate the sensor. The piezoelectric transducer can be bent by deformation work that is emitted from the energy storage device.
