A prosthetic device including a power storage unit to power the prosthetic device and an electromagnetic receiver including a plurality of coils arranged about a portion of the prosthetic device. The electromagnetic receiver is configured to receive a magnetic field from an electromagnetic transmitter magnetically coupled with the electromagnetic receiver and to generate electric power from the magnetic field. Circuitry of the prosthetic device stores the electric power generated from the magnetic field in the power storage unit. The electromagnetic transmitter includes circuitry configured to receive power from a power supply and a plurality of coils configured to generate the magnetic field using the electric power.
