Micro Machines and Opto-Electronics on a Contact Lense

Batman's suit interface telling him information about his environment and metrics about his own body may just be possible through using contact lenses.

Mathematician and SF writer Vernor Vinge has a thing for contact lenses. Wearing the special contact lenses he describes in his fiction –- coupled with computers in clothing and locational sensors scattered everywhere –- his characters see a constant stream of text and virtual sights overlaying the real world.

Fiction now meets reality with prototype contact lenses developed by Babak Parviz at the University of Washington, in Seattle. Dr. Parviz’s prototype lenses can be used as biosensors to display body chemistry or as a heads up display (HUD). Powered by radio waves and 330 microwatts of power from a loop antenna that picks up power beamed from nearby radio sources, future versions will also be able to harvest power from a cell phone.
