From materials to systems: resonant inductive coupling for wireless bioelectronics
Abstract Wireless bioelectronics require alternatives to rigid, bulky batteries for long-term monitoring. This paper reviews resonant inductive coupling (RIC) as an efficient biocompatible power strategy surpassing conventional batteries. We summarize fundamental RIC principles and design parameters for biological environments. We then discuss material and structural strategies for soft, electrically stable coils and their integration into sensing, communication, and closed-loop platforms. Finally, we highlight recent advances in bioresorbable inductive coil systems.
