Abstract

In order to increase the energy transmission efficiency of the wireless transcutaneous energy system for implantable microelectronic neural bridge, this paper focuses on the design of the receiving coil. Several methods are used to improve the performance of the receiving coil design. For both the transmitter and receiver the series resonant circuits are adopted, with a 10-mm distance of coils´ air gap and a 1-kΩ equivalent load, the receiver can attain a transmission efficiency of 26.9%. In addition, the system with stable ±3.3V DC dual sources can supply power for subsequent circuits. The experimental results demonstrate that the system can increase energy transmission efficiency by using the improved receiving coil.
