Abstract

Through-wall ultrasound power transfer (TWUPT) systems have gained interest in many engineering applications thanks to their superior efficiency and wireless connection. In this paper, we propose the use of non-uniform electrode configurations attached to the face of the piezoelectric transducer and receiver for selective mode excitations. A finite element model is created to simulate the TWUPT system and predict the best electrode patterns. For a wide range of vibration modes, the simulation results are compared to their experimental counterparts. This work was supported by the U.S. National Science Foundation (NSF) under grant No. ECCS 1711139 and CAREER No. CMMI 2143788, which are gratefully acknowledged.
