LED Contact Lenses

Another day, another step closer to the world of sci-fi movies… I saw an article this week on the Elemental LED blog about electronic contact lenses that would allow wearers to view dynamically constructed images on the surface of their eyes. The work, much of which has been occurring at the University of Washington, has been underway for a while (for instance, here is an article from 2008 that gives some more details about the tecnology), but it is a great example of some cutting edge research pathways that I am really excited about for the next few years, including energy harvesting, micro-scale electronics, and bio-compatible systems. I think we are probably a long way away from seeing anything like this on the market but even the progress to date opens up worlds of possibilities. Heads-up displays, indeed.
