WiTricity - Wireless Power Transfer by Non- radiative Method
WiTricity, Magnetic resonance, strong coupling, Resonant wireless energy transfer.
Nowadays Electricity has become a cup of life. The transmission of electricity without use of electrical wires is made possible by a method called “WiTricity” will facilitate to Transfer power without using wires. The efficient midrange power can be transmitted to any device which uses that range of power by the technique used in this WiTricity concept. The principle behind the working is Magnetic Resonance. Two resonant objects at ‘strong coupled’ regime tends to exchange their energy efficiently through this method. Two coils having same magnetic resonance one coupled to the source and other coupled to the device. The resonance transmitter emits a non–radiative magnetic field resonating at MHz frequencies and receiving unit loads resonating in that field. Midrange power implemented here is Omni directional, efficient irrespective of the environment. Nowadays there is a rapid influence of electronic devices rely on chemical energy storage (Battery). As they are becoming our daily needs wireless energy transfer would be useful for many applications.
