University of Washington researchers are developing optoelectronic systems embedded in a contact lens to create Terminator-like augmented-reality displays and for noninvasive monitoring of the wearer’s biomarkers (such as glucose levels) and other health indicators on the surface of the eye.

The systems incorporate control circuits, communication circuits, and miniature antennas into the lens, and will eventually include miniature lasers, passive pixels, or hundreds of LEDs to form images in front of the eye, such as words, charts, and photographs.
