WiTricity
The Wireless Transmission of Electricity
Nayara Montes
Introduction
Modern electricity generation system: Transmission and distribution
losses;
A lot of clutter in the process…
√ WiTricity can be the solution!
History
1893: Nikola Tesla’s experimental proof.
4
2007: Experiment of a MIT’s research group.
2011/ 2012: Powermat Wireless Charging.
MIT’s principle of operation
» Two copper coils, each a self-resonant system;
» Resonant source;
» Resonant capture device;
» The space hadn’t radioactive magnetic field;
5
2007: Equipment wireless power transmitter used in the tests at MIT.

Advantages
 Transmission can be possible if
there is any obstruction;
 No need of power cables and
batteries;
 It does not interfere with radio
waves;
 Wastage of power is small;
 Harmless to our health;
 More efficient than
electromagnetic induction;
 Less costly.
7
Disadvantages
 Small range.
