Wireless energy delivery and data communication for biomedical sensors and implantable devices

Abstract

In this paper, we present a wireless power transfer and communication method for biomedical sensors and implants by taking advantage of recently developed witricity technology. New witricity resonator and system designs are described and evaluated by performing both in vitro and in vivo experiments. When compared to the current designs, these new witricity designs demonstrate much improved performances for wireless energy delivery to and data communication with biomedical sensors and implantable devices from outside the human body, providing a higher efficiency and a longer transmission distance.
