Abstract:

To improve the efficiency of the energy transmission system, a method that can obtain the density gone through the receiving coil, will mainly used in study on the magnetic field that created by the transmitting coil, and stimulate the field with a sort of shape function is proposed. Because of using rectangle and circle as the transmitting coil differentiate the effect of transmission efficiency, we need to find out the optimal shape of the transmitting coil. The results say that rectangular transmitting coil can provide energy for four devices simultaneous, and more effective than circle coil.

Key words: implantable device, wireless energy transfer, shape function
