WiTricity is a US engineering company that manufactures devices for wireless energy transfer through resonant energy transfer based on oscillating magnetic fields. The term WiTricity was used for a project that took place at MIT, led by Marin Soljačić in 2006. MIT researchers successfully demonstrated the ability to power a 60 watt bulb wirelessly using two 5-turn copper coils of 60 Cm (24 in) diameter, which were 2 m (7 ft) away, with an efficiency of approximately 45%. The coils were designed to resonate together at 9.9 MHz (wavelength ≈ 30 m) and were oriented along the same axis. One was inductively connected to one power supply, the other to a light bulb. The installation turned on the light bulb, even when the direct line of sight was blocked using a wooden panel. The researchers were able to power a 60-watt bulb with an efficiency of about 90% at a distance of 3 feet.
Emerging technology was demonstrated in July 2009 by CEO Eric Giler at the TED Global Conference held in Oxford. There it refers to the original idea, first applied by the physicist Nikola Tesla between its coils, and shows a WiTricity power unit that feeds a television as well as three different cell phones, the initial problem that inspired Soljacic to get involved with the project. The automaker Toyota made an investment in WiTricity in April 2011. In September 2012, the company announced that it would make a $ 1000 demonstration kit available to interested parties to promote the development of commercial applications.
