Abstract
A sonic transducer includes a transducer body and a drive element coupled to the transducer body to produce a sonic output in response to an applied electrical input. A sense element is coupled to the sonic drive element and is configured to provide an electrical feedback output related to the sonic output. The electrical feedback output is adapted to be used to control the applied electrical input to the sonic drive element so as to control the energy delivered to the working area or tip of the transducer.
