Scientists working at the University of Washington are developing a method to place micro circuitry that is only a few nanometers thick, on a contact lens. The circuitry is being attached to very small Light Emitting Diodes (LED's) only 1/3 of a millimeter wide.
The plan is to use radio waves and solar radiation to power the circuitry on the lens. Micro solar cells would be one choice for power production. This is really cool stuff, but you might be asking yourself, what would I ever use such a thing for?
Some of the potential uses for this technology is in projecting an image that looks like its on the surface you are focusing on. So say you are looking at the windshield of your car, this would make it look like the image is on the windshield; even though it is on top of your eye.
So mobile internet in your eye could be on its way, yet I can't see myself needing the internet that badly. Other uses for this would be interesting to see, maybe a Heads Up Display for pilots, no matter where your head may be turned, even for airline pilots.
The possiblities for this are truly endless.
