"Some day maybe we'll have full-fledged streaming in your contact lenses," said Babak Amir Parviz, an associate professor of electrical engineering at the University of Washington who co-authored a paper describing the computerized new contact lens in the latest issue of the Journal of Micromechanics and Microengineering.
...The engineers took an extremely small custom-designed LED made with sapphire and embedded it in the center of a plastic contact lens. They also embedded a circular antenna around the inside lip of the lens. A miniature integrated circuit connects the antenna and the blue LED. Using remote radio frequency transmission, the group was able to control a single pixel.
This is extremely cool. Someday we could walk around totally integrated with the World Wide Web!
