The nerve electrical stimulation is an effective way to treat neuropathic diseases. Normally, the mice are the subjects for neural stimulation. In order to solve the problem of decreasing transmission efficiency and frequency mismatch of wireless power supply during the experiment caused by the movement of the mice, a squirrel cage system based on wireless power transfer combined with temporally interference is proposed in this paper. The low frequency envelope current superimposed by high frequency power supply with small frequency difference is used for nerve electrical stimulation. It is proved by simulation and experiment that the proposed squirrel cage system can generate stable magnetic field in more than 80% area when the operating frequency is 300 kHz.
