Automatic Control of Inductive Energy Transmitted to Electronic Implants
Many studies have shown that power transmission by inductive link is the most efficient method for powering biomedical implants.However,electronic implants may not work properly if there is insufficient power delivery due to the variation of the primary resonant frequency thus being influenced by several parameters such as coupling factor between coils,load variation on the receiver side,temperature fluctuations and aging components.This paper introduces a new method for compensation of both transmitter and receiver variations.The proposed method is based on an inductive power transmitter integrating a primary coil voltage feedback monitoring circuit and a high precision stepper motor that dynamically tunes the primary resonant capacitor to achieve resonance condition.The proposed transmitter showed remarkable improvements compared to manually tuned transmitters.It also allows powering various implants,without intervention of the designer.The system testing’s results are reported and discussed.
