WiTricity , a portmanteau for "wireless electricity ", is a trademark of WiTricity corporation [ 1 ] referring to their devices and processes which use a form of wireless energy transfer including resonant energy transfer etc., the ability to provide electrical energy to remote objects without wires using oscillating magnetic fields. The term WiTricity was used for a project that took place at MIT , led by Prof. Marin Soljačić in 2007. [ 2 ] [ 3 ] WiTricity is based on strong coupling between electromagnetic resonant objects to transfer energy wirelessly between them. This differs from other methods like simple induction, microwaves, or air ionization. The system consists of transmitters and receivers that contain magnetic loop antennas critically tuned to the same frequency.

Cell phones, game controllers, laptop computers, mobile robots, even electric vehicles capable of re-charging themselves without ever being plugged in. Flat screen TV’s and digital picture frames that hang on the wall—without requiring a wire and plug for power. Industrial systems and medical devices made more reliable by eliminating trouble prone wiring and replaceable batteries. WiTricity Corp. is working to make this future a reality, developing wireless electricity technology that will operate safely and efficiently over distances ranging from centimeters to several meters—and will deliver power ranging from milliwatts to kilowatts. WiTricity Corp.’s vision is to develop a family of wireless electric power components that will enable OEM’s in a broad range of industries and applications to make their products truly “wireless.”

TMC and WiTricity Form Wireless Battery-charging Alliance | TOYOTA MOTOR CORPORATION GLOBAL WEBSITE
Apr. 27, 2011 Toyota City, Japan, April 27, 2011—Toyota Motor Corporation (TMC) has entered into a technological collaboration agreement with Massachusetts, United States based WiTricity Corporation * concerning the practical application of automotive wireless charging systems and the promotion of their widespread use. TMC plans to participate in a WiTricity capital increase.
WREL, demonstrates wireless power transfer whose efficiency can be nearly independent of orientation, distance, and load over a wide range of operating conditions. This technology could allow people to cut that last cord. In the past few years, we have experienced a dramatic rise in the number of electronic devices-cell phones, digital cameras, laptops, etc.-that we use in our everyday lives. Most of these devices are powered by batteries which need to be recharged very often.
