A wide-band efficient inductive transdermal power and data link with coupling insensitive gain

This paper describes a new method of desensitizing the gain of an inductive link to the mutual coupling of its inductors. When the coupling varies due to geometrical misalignments this design method guarantees good efficiency and a large bandwidth. The mathematics for four link combinations are pres...

Summary:This paper describes a new method of desensitizing the gain of an inductive link to the mutual coupling of its inductors. When the coupling varies due to geometrical misalignments this design method guarantees good efficiency and a large bandwidth. The mathematics for four link combinations are presented, and examples of the link efficiency and bandwidth for one of the combinations are shown and discussed.
