Abstract
A system for wirelessly charging an implantable device is described. The system may include an estimation device or component that estimates a field strength at a receiving coil of the implantable device based on available electrical signals within the implantable device. The system may also include a control system for varying a strength of a charging field produced by a charger. The system may also be used to align a wireless charger with the implantable device for charging a battery of the implantable device. Methods and devices for implementing the charging system are also described.
