Abstract

In this research, 2nd harmonics are exploited for distance adaptation wireless power transfer (WPT). Thanks to the intrinsic discontinuity relation between 2nd harmonics and its incidence, both optimal power delivery and maximum conversion efficiency of an implantable medical device (IMD) rectifier can be tracked simultaneously by tuning the interrogated power to capture an abrupt 2nd-harmonic feedback. Harmonic-balance simulation and experimental results both validate that 2nd-harmonic feedbacks can be exploited for distance-adaptation WPT to IMDs.
