An efficient wireless power link for neural implant
An efficient resonant tuned wireless power transfer (WPT) link using inductive coupling has been proposed for the neural implant application in this work. The power link is optimized for an operating frequency of 10 MHz using coil, load and frequency optimization. The lossy tissue model was used to mimic the power loss in tissue and the simulated (HFSS) peak SAR values were within the allowed limit for 20 mW power received at implant. The power transfer efficiency for implant coil sizes of 250 mm2 for a power transmit range of 10 mm was simulated using HFSS to be around 82%.
