The Effect of Transmitter Coil Size on the Optimal Implantation Depth of Receiver Coil in Transcutaneous Inductive Energy Transfer Systems

Abstract

The effect of patient’s individual characteristics on the output of wireless transcutaneous inductive energy transfer systems has been studied. Numerical modeling shows that small changes in the implantation depth due to patients’ individual characteristics (thickness of skin, subcutaneous fat layer, and bones) can lead to significant changes in output power and efficiency of the energy transfer. Our study shows that the effect of these changes can be compensated by optimizing the size of the external (transmitter) coil.
