Abstract

This paper reports a design methodology for a tri-coil system that can wirelessly transfer power from a macro-scale probe to a chipscale apparatus over a long distance and with a high efficacy. Such systems can be employed for enabling the wireless charging and communication between implanted body sensors and smart phones as well as between hardware roots of trust and their interrogation probes. A design example has been offered and subsequently validated by an experimental testbed consisting of micro-fabricated coils on both sides of a Silicon substrate. As predicted by the analytical models, the measured power transfer efficacy (PTEF) of the designed system is as high as -27 dB at the resonance, confirming an orders-of-magnitude higher PTEF than that of prior WPT systems over a distance greater than 5 times the coil diameter.
