Wireless Charging For All Your Devices Ready For The Market
I’ve followed the development of resonant wireless power transfer technology since it was first theorized in 2007. Now it appears the technology is only one step away from being available to consumers with the developers seeing take-up by original equipment manufacturers (OEMs). The company has also displayed a wireless charging system designed for the iPhone 5 as proof of the capability and readiness of the technology for market.
MIT Professor Marin Soljačić dreamed back in 2006 of a world where portable devices would charge themselves, without the need to plug in, place on a surface or be positioned carefully on an induction mat ever again. He wanted an easy and safe wireless charging system capable of working at mid-range distances and through a variety of surfaces.
WiTricity unveiled it’s charging system for the iPhone 5/5s at CES 2014 that it was capable of charging two phones at once without being in direct contact with the charging hub. Using a specialized iPhone 5 cover, fitted with magnetically coupled resonators, the device is able to be wirelessly charged.
Capable of charging devices over a distance of up to 8.2 ft (2.5 m) with an efficiency of up to 90 percent, the system utilizes non-radiative energy transfer known as near-field magnetic coupling. As it does not rely on direct contact or line-of-sight, and can charge devices through a range of materials, the applications are shaping up to be many and varied. The technology can be scaled to power levels ranging from a few milliwatts to several kilowatts, allowing WiTricity the versatility to charge everything from your iPhone to an electric car.
