Yeah some guy over at Anandtech in the comments section was pointing that out. He posted a video talking about MS and UW working on this exact same thing two years ago. Yet now that Google is playing around with it, it's all over the internet like wildfire and they're being praised as innovators, despite the fact that they were far from the first. Google is becoming the new Apple.
Perhaps they found the technology to be impractical two years ago and had to wait? Don't be so quick to judge

From other source:"If you're wondering how power works, one of Praviz's previous projects was a contact lens with a working LED. Power for that was described as being "powered remotely using a 5-millimeter-long antenna printed on the lens to receive gigahertz-range radio-frequency energy from a transmitter placed ten centimetres from the eye." The copper circle around the edge of this lens is most likely an inductive charging coil, so actual use of this will probably require some kind of face-mounted charging antenna."Makes the concept a little less cool if you ask me.Source: http://arstechnica.com/gadgets/2014/01/google-introduces-smart-contact-lens-project-to-measure-glucose-levels/How is this powered? off of natural RF or does it come with a special RF Transmitter that you must be close to?
