OBJECTIVES•Investigate feasibility of wireless power transfer via inductive resonant coupling•Design and implement a coupled network to quantify power transfer efficiency

FUTURE WORK•Achieving >50% efficiency•Making circuit network more stable•Increasing distance between circuits•Decreasing circuit size

FINDINGS•Peak power transfer by simulation @ 1MHz•Highest Efficiency –> 62%•Small changes in coil result in large changes in inductance values

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
