abstract：

Although recent technological advances have  produced numerous implantable medical devices, these devices must have a power  supply. A battery is not a good option since replacing it requires a surgery.  Two novel approaches are studied to deliver power wirelessly into the body. The  first approach uses the volume conduction property of biological tissue as a  natural “cable”. A flexible epidermal sheet delivers energy into the body  mimicking the mechanisms of an electric fish. In the second approach, the  wireless electricity is utilized based on strongly coupled mid-range resonance  with a much higher efficiency than the traditional magnetic induction  method.
