Smart Table Applications Based on Magnetic Resonance Wireless Power Transfer

Magnetic resonance wireless power transfer (MWPT) technology can potentially simplify the electrical cable layout and routing for indoor environment due to its relatively long transmission distance and high efficiency. Targeting at smart table applications, a series-series matching two-coil MWPT powered LED system operating at 28 cm optimal operating distance is designed and characterized. The effects of the varying operating distances and different blocking materials on the power transfer are studied. In addition, the system performances under different operating frequencies are also measured and analyzed.
