WiTricity:Wireless Power Transfer By Non-radiative Method
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 11, Issue 6
Abstract
A non-radiative energy transformer, commonly referred as WiTricity and based on ‘strong coupling’ between two coils which are separated physically by medium-range distances, is proposed to realize efficient wireless energy transfer. WiTricity idea is spear-headed by MIT researcher Marin Soljacic, which describes the ability to provide electricity to remote objects without wires. The advent of WiTricity technology is though old of 1899, explored by Nikola Tesla, but has founded its grip in recent years with numerous gadgets and there snaking cables around us. The technology is in turn expels E-waste and will free us from the power cords. WiTricity depends upon strong coupled resonance between transmitter and receiver coils. The transmitter emits a non-radiative magnetic field resonating at MHz frequencies and the receiving unit load resonates in that field. Thin film WiTricitycells, consisting of a tape coil on one layer, which is separated by an insulation layer to conductive strips on another layer, are fabricated. These cells are light, compact, and flexible provide convenience and flexibility in the design of wireless devices. Experiments are conducted to showcase the performance of this energy transfer system.
