Abstract :
This paper investigates wireless electricity (witricity) and its application to medical sensors and implantable devices. Several coupling scenarios of resonators are analyzed theoretically. In vitro experiments are conducted in open air and through an agar phantom of the human head. An in vivo animal experiment is also carried out. Our studies indicate that witricity is a suitable tool for providing wireless power to a variety of medical sensors and implanted devices.
