A Non-Radiative Wireless Power Transfer System for Medical Implant Deployment: An Experimental Validation

Wireless Power Transfer (WPT) systems employing magnetic resonance technology offer a compelling solution for providing seamless power delivery in scenarios where conventional electrical connections are impractical. This research focuses on designing and developing a magnetic resonance-based WPT system explicitly tailored for powering battery-operated pacemakers, addressing the limitations posed by traditional wired connections, particularly in medical contexts. Through numerical modelling and experimental validation using a constructed test-rig setup, the performance of the WPT system was assessed, with a specific emphasis on input–output power efficiency. The results demonstrate efficient power transmission from the transmitter to the receiver over a separation distance of 100 mm. Experimental validation further corroborates the effectiveness and reliability of the developed system, yielding a high correlation coefficient of 0.98. This research advances the wireless power transfer field, particularly in medical device applications, paving the way for enhanced patient care and technological innovation.
