At the outset we sincerely thank God for having got my project completed in time. Firstly, we thank our parents who have been a motivation factor throughout our lives. Secondly, we sincerely thank Dr. Mohammed Ismail , HOD, ECE Dept., Krishnamurthy Institute of Technology & Engineering for his kind cooperation and encouragement for successful completion of technical seminar report. We are most obliged and grateful to our principal and internal guide (Mr.Sanjay Kashi), for giving us guidance.
The world has always been galloping in the chariot of technological wonders, where change is constant. Adding a feather in the cap of modern technological wonder babies, science has given birth to a robust mechanism called ‘WITRICITY’. Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However, to us 21st centurions, the light bulb is nothing out of the ordinary. When computers, cell phones, Laptops, iPods, etc. were invented our antennas tweaked. Now this is what you call invention! However, as time’s progressing we are getting used to these devices. In fact, charging all these appliances has become so very cumbersome. Each appliance has its own set of chargers, and with every family member owning their cell phones, the drawers are overflowing with all sorts of wires. How many times have you wished if there could be some way to do away with all the wiry clutter? When you are on the way to work and your cell phone beeps in hunger for a battery charge, haven't you wished for...
