Implantable medical devices must function in the body for long periods of time; hence, efficient rechargeable power sources must be developed to non-intrusively recharge these devices. In the charging process, implantable medical devices will damage the surrounding tissue due to the resulting heat generation. In order to enhance the charging efficiency and decrease the temperature variation, a 200-mAh Li-polymer battery was charged by a multistage sinusoidal current with the minimum-ac impedance, and an optimal rapid-charging pattern was identified by the Taguchi method. Experiment results showed that in terms of charging efficiency and battery and tissue temperature control, a multistage sinusoidal current with the minimum-ac-impedance frequency performed best compared with constant current (CC), pulse current, temperature compensation circuit and and constant current constant-voltage (CC-CV) charging strategies. In terms of battery temperature variation, compared to the above-mentioned three charging methods, the temperature compensation circuit has the best result, respectively; in respect to charging efficiency, the multistage sinusoidal current has the best performance.
