摘要: Abstract This paper investigates ultrasonic transcutaneous energy transfer (UTET) as a method for energizing implanted devices at power level up to few 100 mW. We propose continuous wave 673 kHz single frequency operation 40 mm deep subcutaneously. The proposed UTET demonstrated an overall peak efficiency of 27% 70 mW output (rectified DC the load). transducers consisted PZT plane discs 15 mm diameter and 1.3 mm thick acoustic matching layer made graphite. rectifier on implant side attained 88.5% efficiency. approach is analyzed in detail, with design considerations provided address issues such recommended operating range, link matching, receiver’s rectifying electronics, tissue bio-safety concerns. Global optimization maximum are presented verified by means finite element simulations experimental results.
