Abstract
This chapter introduces the fundamentals of wireless power transfer used for implant powering. An overview of several possible methods for the power source is exhibited, and the hybrid choice of remote powering and a rechargeable battery is justified. The choice of magnetic coupling as a power transfer method is explained. Moreover, the 4-coil inductive link and the required integrated circuits to create a stable power supply for remote powering are presented. In addition to the power receiving circuits, supplementary blocks are introduced to increase the power transfer efficiency.
