Abstract

A modular multiple frequency coils inductive link system to wirelessly provide power for at least a medical implant at an output of a receiving coil, whereby the receiving coil is configured to be implanted in an organism. The modular multiple frequency coils inductive link comprises a transmitter coil configured to input power from a power supply and induce a first magnetic field at a resonating carrier frequency. The modular multiple frequency coils inductive link further comprises a shifting resonator comprising at least an active integrated circuit, a first coil configured to receive the first induced magnetic field from the transmitter coil by induction at the resonating carrier frequency and convert it to an electrical current, and a second coil configured to transmit the electrical current to the receiving coil by inducing a second magnetic field at a determined frequency different from the resonating carrier frequency, the active integrated circuit connected with both the first coil and the second coil and being configured to receive the power induced at the resonating carrier frequency though the first coil and to use it to drive remaining power reduced due to a power dissipation of the active integrated circuit at the determined frequency though the second coil. The receiving coil is configured to receive the power induced by the second coil at the determined frequency and make it available at the output of the receiving coil.
