WiTricity. WiTricity is an American engineering company that manufactures devices for wireless energy transfer using resonant energy transfer (oscillating magnetic fields).
History The term WiTricity was used for a project that took place at MIT, led by Marin Soljačić in 2007. The MIT researchers successfully demonstrated the ability to power a 60 watt light bulb wirelessly, using two 5-turn copper coils of 60 cm (24 in) diameter, that were 2 m (7 ft) away, at roughly 45% efficiency. The coils were designed to resonate together at 9.9 MHz (≈ wavelength 30 m) and were oriented along the same axis. One was connected inductively to a power source, and the other one to a bulb. The setup powered the bulb on, even when the direct line of sight was blocked using a wooden panel.
Researchers were able to power a 60 watt light bulb at roughly 90% efficiency at a distance of 3 feet. Arduino - HomePage. Electronic and Electro-Mechanical Parts and Su. Resonant energy transfer.
