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.” Wireless electric power delivered over room scale distances, and with high efficiency. Wireless electric power that is safe for people and animals. Wireless electric power—imagine no more… it’s here!
How it came up
”Marin Soljačić couldn’t sleep. The problem was his wife’s Nokia cell phone. The tyrannical device beeped on the bedside table when it needed to be plugged in. It could not be disabled. Instead of taking a hammer to the phone, Soljačić marveled at the fact that this device, and billions of others like it, was sitting a few feet away from all the electricity it could ever need. Why couldn't it receive power wirelessly, just as laptops get Wi-Fi?
Understanding what WiTricity technology is—transferring electric energy or power over distance without wires—is quite simple. Understanding how it works is a bit more involved, but it doesn’t require an engineering degree.
How it works
The prototype system demonstrates wireless powering of an LCD TV. In this demonstration system, a WiTricity power source is positioned on the floor. It is connected to AC power and converts AC current to an oscillating magnetic field. The WiTricity capture device (to the right of the LCD TV), converts the magnetic energy to alternating current and powers the LCD TV. The WiTricity power source and capture devices are highly resonant magnetic systems that can exchange energy in a very efficient manner.
