Design on Magnetic Coupling Resonance Wireless Energy Transmission and Monitoring System for Implanted Devices

With the increasing use of medical human implant devices, wearable equipment, and other microelectronic systems, the wireless energy supply for these device or system plays a very important role in their applications. This paper presents a wireless energy transmission system based on magnetic coupling resonance technology for implanted devices. The system consists of two parts: a source (in vitro) and a receiver (in vivo) with the function of an information monitoring system of an equipment state. The simulation of resonance frequency has been carried out in the different parameters of the resonators, based on coupled mode theory with the help of Ansoft software. The power transmission efficiency has been analyzed with three different conditions (in the air, simulation human tissue fluid and fresh pork). The results show that this system not only realizes wireless power transmission for battery charging but also monitors the battery voltage, current, and temperature in real time.
