Based on the principle of electromagnetic coupling, a set of wireless energy supply system was designed for the artificial anal sphincter system. The system contains five parts: wireless energy transmitter, wireless energy receiver, rectifier module, regulator module and charging module. This work focuses on the effect of transmitter launch angle frequency (40-120kHz) on the transmission power. We compare the charging effect and optimize the regulator module to meet the executing agency operating power requirements. The experiment results show that the transmission efficiency improves with the increase of the transmission frequency in a certain frequency range. When the transmission frequency is 120kHz, the transmission efficiency can reach 57.47%, the receiving power is 1.12W, and the lithium battery can be quickly charged, providing stable energy for the artificial anal sphincter system.
