Goodbye wires…
CAMBRIDGE, Mass. --- Imagine a future in which wireless power 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 team members 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 Soljačić. Realizing their recent theoretical prediction, they were able to light a 60W light-bulb from a
power source seven feet (more than 2 meters) away; there was no physical connection between the source and the
appliance. The MIT team refers to their concept as “WiTricity” (as in Wireless Electricity). The work will be
reported in the June 7 issue of Science Express, the advance online publication of the journal Science.
