Abstract :
The safety of power supply for biomedical implants is critical in an implantable system. In this paper, an adaptive feedback with pulse width modulation (PWM) and load shift keying (LSK) is introduced and used in the design of a wireless power transmission system. Experimental results show that the system can receive stable power when the distance between the transmitter and receiver changes. Compared to the system without adaptive feedback, the efficiency is improved by 5.7 times with the distance under 20mm.
