  1. Wireless Power Transfer Research Team: Amir Shahidi, SandunmaleeAbeyratne, JoyetaSamanta, Christopher Lyons, Zachary Wilson, HershLalwani Advisors: DimitriosPeroulis • OBJECTIVES • Investigate feasibility of wireless power transfer via inductive resonant coupling • Design and implement a coupled network to quantify power transfer efficiency • ABOUT RESONANT CIRCUITS • Inductor/Capacitor circuit network • Resonantly coupled circuits allow for minimal energy losses • At common frequency power can be sent over several coil diameters • METHODS • Circuits composed of bare copper wire formed into coils to form inductors. • Driver Circuit transmits signal to receiver • Receiver circuit dissipates signal across a load. • FINDINGS • Peak power transfer by simulation @ 1MHz • Highest Efficiency –> 62% • Small changes in coil result in large changes in inductance values 15 µH • FUTURE WORK • Achieving >50% efficiency • Making circuit network more stable • Increasing distance between circuits • Decreasing circuit size 1 µH
