Witricity

I was watching this video at here and found it really interesting. Posting it here for my own reference. 





Can you imagine the convenience of a wireless chargers for things like your cell phone, your iPod, and digital cameras? 


You would never have to plug in your wireless charger to an electrical socket, because this new wireless charger has a charging system that uses electromagnetic induction to accomplish wireless charging of your devices.

It is basically a concept of creating a magnetic field that runs parallel to the surface of the pad, rather than out the end of the pad. In doing this, it enables delivery of a very uniform output of magnetic force across the pad, and makes it possible to make a receiver coil that is thin in the wireless chargers. 


WiTricity, a portmanteau for "wireless electricity", is a trademark of WiTricity corporation referring to their devices and processes which use a form of wireless energy transfer, the ability to provide electrical energy to remote objects without wires using oscillating magnetic fields.
