INTRODUCTION
Now day‘s electricity has become a cup of life. A moment without electricity makes your thinking go dry. The
major source of conventional form of electricity is through wires. The continuous research and development has brought
forward a major breakthrough, which provides electricity without the medium of wires. This wonder baby is called Witricity.
There are certain small but very useful discoveries made in history, which changed the world for ever, Newton‘s
gravitational law, Watt‘s steam engine, Thomson‘s bulb and many more. But a renaissance occurred with the invention of
Electromagnetic Waves by Maxwell. Sir Jagdish Chandra Bose successfully generated electromagnetic waves having
wavelength in the range of 5mm to 25 mm. Thereafter an Italian scientist named Marconi succeeded in transmitting
electromagnetic waves up to a distance of several miles. And with this there started a new era called WIRELESS
TECHNOLOGY. Today, as we can see the word ‗wireless‘ is common in day – to – day life. Wireless communication has
made the world smaller. Almost each and everything is wireless or cordless. Cordless mouse, cordless keyboard, satellite
communication, mobiles, cordless microphones and headphones, wireless internet service i.e. WIFI, etc. And these have
definitely increased the standard of living. In fact it dates back to the 19th century, when Nikola Tesla used conduction based
systems instead of resonance magnetic fields to transfer wireless power. As it is in Radioactive mode, most of the Power was
wasted and has less efficiency. Further, in 2005, Dave Gerding coined the term Witricity which is being used by the MIT
researchers and today‘s world.[1]
CONCLUSION
This provides mid-range non-radiative energy transfer scheme based on strongly-coupled resonances. Even very
simple design have promising performance and provides better efficiency with respect to distance. As a powerful concept, it
could enable a wide range of applications. We can call WiTricity as future technology of Electricity transmission for power
