3. WITRICITY

5. RESONANCE COUPLING A group of engineers at MIT came up with the idea to use resonant induction to transmit power wirelessly. “Resonance", a phenomenon that causes an object to vibrate when energy of a certain frequency is applied. The forgotten invention is reborn in 2007

6. Need of Witricity: Now a days there is a Rapid development of autonomous electronics like Laptops , Cell-phones , House-hold robots and all those devices typically rely on chemical energy storage(Battery) As they are becoming daily needs to present generation, Wire less energy transfer would be useful for many applications as above and they need midrange energy.

11. Witricity Tomorrow 1) Power from mains to antenna, which is made of copper 2) Resonates 10MHz (electromagnetic waves) 3) Tunnel up to 2m (6.5ft) 4) Electricity received by antenna, also resonating at 10MHz. 5) Energy not transferred to laptop re-absorbed by source antenna. People/other objects not affected as not resonating at 10MHz

12. Basic Principle: The basic principle involved in Witricity concept is, Two objects having same resonating frequency and in Magnetic resonance at Strongly coupled regime tend to exchange energy , while dissipating relatively little energy to the extraneous off-resonant objects.

13. Experimental Design: Our experimental scheme consists of two Self-resonant coils. One coil (source coil) is coupled inductively to an oscillating circuit; the other (device coil) is coupled inductively to a resistive load. Self-resonant coils rely on the interplay between distributed inductance and distributed capacitance to achieve resonance.
