Babak Amir Parviz, an engineer led a team, which successfully displayed a single, remotely-controlled pixel onto a contact lens worn by a rabbit.
To create the computerized contact, the engineers embedded a circular antenna along the rim of the lens, and coupled it with a tiny LED via an integrated circuit. Using remote radio frequency transmission, the researchers can control the activity of the single pixel, which is situated at the center of the lens.
As of now this has been tested on animals only, It might soon be availble for human usage aswell with new reaserch going on. Then, may be we humans too can communicate like those robots from sci-films like terminator and iRobot.
The researchers describe their computerized contact lens in the latest issue of the Journal of Micromechanics and Microengineering
