摘要
Near-field resonant inductive coupling is the most mature wireless power transfer (WPT) method for implantable medical devices. Common commercial WPT components are not optimized neither to deliver small amounts of power nor to work with other than small air gaps. In this paper, a closed-loop control is integrated with commercial off-the-shelf WPT components to efficiently recharge and power an implantable device for controlled active drug delivery. The system keeps the transmitted power stable and reliable, achieving a 26 % transfer efficiency with delivered power of tens of milliwatts, guaranteeing an autonomy of 5 days with a 4-hour recharge. Overheating is kept around the 2 °C safety limit.
