Abstract
Ultrasound acoustic energy transfer (UAET) is a transformative contactless energy transfer (CET) technology that outperforms conventional electromagnetic based CET techniques to recharge and communicate with low-power implanted medical devices which eliminates the need for invasive surgery. The limited modeling and proof-of-concept experiments on AET were performed in the linear range with several assumptions by neglecting the nonlinear wave propagation and the electroelastic nonlinearities of transmitter and receiver that become significant at higher source strengths and influence energy transfer characteristics. We present a series of experiments and experimentally-validated multiphysics models that we considered to address the knowledge gaps in UAET.
