WiTricity

WiTricity Corporation provides technology to enable wireless power transfer over distance using magnetic resonance.

WiTricity Corp. was founded in 2007 to commercialize an exciting new technology for wireless electricity invented two years earlier at the Massachusetts Institute of Technology (MIT). A team of physicists, led by Professor Marin Solja developed the theoretical basis for this novel method for wireless electric power transfer in 2005, and validated their theories experimentally in 2007. The magnetic fields of two properly designed devices with closely matched resonant frequencies can couple into a single continuous magnetic field. Prof. Solja team showed how to use this phenomenon to enable the transfer of power from one device to the other at high efficiency and over a distance range that is useful for real-world applications. This âœstrong coupling” enables the devices to exchange energy via magnetism, and avoids the potential safety hazards and inefficiency often associated with radiated electro-magnetic energy. Their demonstration of wireless power transfer showed a 60 watt light bulb being illuminated from a power source over 2 meters away, and their results were published in the prestigious journal Science in July 2007. Prof. Solja was recognized with a MacArthur Fellowship in September 2008, awarded by the John D. and Catherine T. MacArthur Foundation. In addition, his work was recognized as one of the Top Ten Emerging Technologies for 2008 by Technology Review, Top 100 Science Stories of 2007 by Discover Magazine, and cited in The New York Times Magazine: The Year in Ideas 2007.
