Magnetic Resonance based Soft Electronic Implant for Wireless Electrotherapy and Thermal Ablation

This study explores the potential of magnetic resonance wireless power transfer (MR-WPT) for non-invasive medical applications, addressing limitations of traditional power sources in bioelectronic implants. By leveraging resonant coupling, MR-WPT achieves efficient energy transfer across biological barriers with minimal attenuation. A flexible printed circuit board (fPCB)-based MR-WPT network is developed to deliver wireless, battery-free power to implants, demonstrating resilience to geometric changes, such as separation, offset, and tilt. Experiments highlight its capability to maintain high power transfer efficiency under varied conditions and validate its functionality in targeted thermal ablation and customized electrical stimulation. The results suggest that MR-WPT could revolutionize bioelectronic implant design, offering enhanced safety, reliability, and therapeutic efficacy.
