A Novel Approach for Supplying Wireless Energy to Multiple Devices Simultaneously Using Sweeping Effect

Abstract

There has been great interest in wireless power transmission since 2007 when a novel approach was presented by a group of scientists at MIT. With this new technique, power transmission range is possible for a couple of meters with high efficiency; however, to be able to use this technique in our lives with high efficiency and long transfer range, small structured devices and new design techniques are strongly required. In this chapter, the investigation on supplying energy by sweeping was presented. The experimental results claim that energy could be supplied to multiple devices almost at the same time. If the range of chosen frequency increases, the number of devices could be increased as well, considering slight energy efficiency loss in the transfer system. The authors hope that the proposed technique gives inspiration to the designers and to the market.
