Witricity - Wireless Power Transfer



Wireless Electricity Transmission:
MIT Researchers Created Witricity (Or Etricity), That Means An End To Multiple Gadgets That Powered Up Your Cellphone, Digital Cameras, Laptop, Or Any Other Electonic Machine At Anywhere Or Home. Franklin Hadley, Institute for Soldier Nanotechnologies June 7, 2007 Imagine a future in which electricity transfer is feasible: cell phones, household robots, mp3 players, laptop computers and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire.

Some of these devices might not even need their bulky batteries to operate. A team from MIT's Department of Physics, Department of Electrical Engineering and Computer Science, and Institute for Soldier Nanotechnologies (ISN) has experimentally demonstrated an important step toward accomplishing this vision of the future. The MIT team members that made the wireless electricity transmission cirquit are Andre Kurs, Aristeidis Karalis, Robert Moffatt, Prof. Peter Fisher, and Prof. John Joannopoulos (Francis Wright Davis Chair and director of ISN), led by Prof. Marin Soljacic.

The key: Magnetically coupled resonance In contrast, Witricity is based on using coupled resonant objects. Two resonant objects of the same resonant frequency tend to exchange energy efficiently, while interacting weakly with extraneous off-resonant objects. A child on a swing is a good example of this. A swing is a type of mechanical resonance, so only when the child pumps her legs at the natural frequency of the swing is she able to impart substantial energy. Video source: YouTube.Com
