1. A method for supplying signals to an electronics module, comprising the steps of:

  • providing an electronics module;

    providing a motion sensitive piezoelectric element having output terminals;

    providing a transmitter inductor having input terminals;

    coupling the output terminals of the motion sensitive piezoelectric element to the input terminals of the transmitter inductor;

    positioning the transmitter inductor proximate the electronics module, andcoupling a conversion circuit between the piezoelectric element and the transmitter inductor, wherein the conversion circuit is configured to convert pulses from the piezoelectric element into narrow width, high energy, pulses for application to the transmitter inductor;

    whereby signals may be supplied by inductive coupling to the electronics module from the motion sensitive piezoelectric element.
