This paper reports on the implementation of a transcutaneous capacitive wireless power transfer (C-WPT) strategy for biomedical implants. The approach is based upon a series resonant converter in which the tank capacitors are replaced with a capacitive link comprising two pairs of coated parallel plates aligned around the tissue as the dielectric material. Miniaturized printed-circuit boards are developed that incorporate all requisite circuitry on the front-side of transmitter (TX) and…

Capacitive coupling for power and data telemetry to implantable biomedical microsystems
Confinement of the transferred energy within a predefined area, hence not influencing the neighboring sensitive circuitry on the microsystem, and also allowing for more than one telemetry link on the same platform and even operating at the same carrier frequency are among the advantages of the proposed method.
