Abstract :
There exist many applications for coupling power wirelessly to devices implanted in the human body. In this paper, we explore the effect of changing the dimensions of the receiving antenna embedded within dry skin while keeping the transmitter´s size and other factors such as the frequency of operation and surrounding materials constant. Using full-wave simulations carried out in HFSS, followed by equivalent circuit simulations in ADS, we arrive at values for the Power Transfer Efficiency, PTE, and the coupling coefficient, k, which can be used to model the wireless link. The dependence of these parameters on the cross-sectional area is studied and the results reported.
