Late scientist Nikola Tesla was the one who first conceived the idea of Wireless Power Transmissionand demonstrated the transmission of electrical energy without wires that depends upon electricalconductivity, as early as 1891. In 1893, Tesla demonstrated the illumination of vacuum bulbs withoutusing wires for power transmission at. the World Columbian Exposition in Chicago. The Wardenclyffetower was designed and constructed by Tesla mainly for wireless transmission of electrical power rather than telegraphy.In 1904, an airship ship motor of 0.1 horsepower is driven by transmitting power through space from adistance of least 100 feet. In 1 961, Brown published The First Paper proposing Microwave Energy for Power transmission, and in 1,964th He demonstrated Microwave-powered Model A The Power needed for all Thatreceived Helicopter Flight from A Microwave Beam at two forty-five GHz from The Range of 2.4GHz.

2.5 GHz Frequency band which is reserved for Industrial, Scientific, and Medical (ISM) applications. Experiments in Power transmission without Wires in The Range of tens of kilowatts have been performed at Goldstone in California in the 1975th and at Grand Bassin on Reunion Island in 1997.

. Inductive coupling is used in Oral-B Rechargeable toothbrushes by The Braun (Company. ) since Early
one thousand nine hundred and ninety's. Research continued in this particular area since then but a very few of them came through. Oneof the remarkable successes among them was the-Powermat ‖. This was The Inspiration of our main.
Project. Powermat came with a special case for each mobile phone which acts as the receiver. Themain dock, which acts as the transmitter, is connected to the electric socket by a wire. But the fact thateach model of mobile phone required different casings, which made it bulky and difficult to carryaround, made us think of something smaller. Hence we came up with the idea of a circuit that could beintegrated into a micro or even a Nano chip and could be implemented inside the low power device bythe manufacturer.
