The wireless power transfer technology with ultrasound has been introduced and several study results have been reported as an alternative wireless power transfer technology. The ultrasonic wireless power transfer system has mainly two components, the transmitter which converts electrical energy to ultrasonic energy and the receiver which changes the ultrasonic energy to the electrical energy again. It is very important for the ultrasonic transducer and receiver to have the high energy transfer efficiency as a transducer or a sensor. The transducer with high energy transformation efficiency would be able to get a high sensitivity as a sensor, or to transmit high wireless energy transferring capacity as a wireless power transducer. The matching layer design is one of the most important factors to get a high energy transfer efficiency of the ultrasonic transducer. This document describes the development of the mathematical model, and the experimental study of the matching layer for an ultrasonic transducer in a wireless power transfer system considering the volume fraction of the piezo ceramic, PMN-30PT and impedance of materials.
