Abstract

In the context of wireless acoustic power transfer, high-intensity focused ultrasound technology aims at the reduction of spreading losses by concentrating the acoustic energy at a specific location. Experiments are performed to determine the impact of nonlinear wave propagation on the spatially resonant conditions in a focused ultrasonic power transfer system. An in-depth analysis is performed to explain experimental observations. The results show that the efficiency of energy transfer is reduced as nonlinear effects become more prominent. Furthermore, the maximum voltage output position shifts away from the focal point and closer to the transducer as the source strength is increased. The results and analysis are relevant to the development of efficient ultrasonic power transfer devices when using focused sources.
