6.78 MHz resonance coupling for implantable medical devices

A shunt-series mixed resonant coupled structure for the implantable medical devices is demonstrated experimentally. The experiment conducted by using 1 cm thickness pork tissue at 6.78 MHz operating frequency. The transmitter coil outside the pork tissue, the 4 cm square coils on 2-layer PCB is used. On the while, the receiver coil inside the pork tissue, 1 cm diameter of copper wire is used. The experimental results of the designed wireless power transfer structure shows successful power transfer to the load inside the pork tissue up to 100 mW.
