In 2007, a team of researchers from the Massachusetts Institute of Technology's (MIT) Department of Physics, Department of Electrical Engineering and Computer Science, and Institute for Soldier Nanotechnologies experimentally demonstrated an important step toward accomplishing a future in which wireless power transfer is feasible. In 2006 Marin Soljacic, an assistance professor of physics at MIT, was dragged out of bed by the insistent beeping of a cell phone. Standing in his pajamas, he wished the phone would just begin charging itself as soon as it was brought into the house. This late-night thought eventually led to Soljacic searching for ways to transmit power wirelessly. He eventually landed on the phenomenon of resonant coupling, in which two objects tuned to the same frequency exchange energy strongly but interact only weakly with other objects. Thus Professor Soljacic's dream of finding a method to wirelessly connect mobile electric devices to the existing electric grid was realized.
