This video show a quadrotor being powered completely wirelessly via magnetic induction. The quadrotor's battery has been removed.
The transmitter was implemented on a two layer PCB and was driven by a load independent Class EF inverter. The inverter operates at 13.56 MHz and uses a single GaN transistor from GaN Systems.
The receiving coil consists a single turn of copper tape which was wound around the shield of the quadrotor. The receiver board consists of a Class D rectifier and a DC/DC converter.
