Tattoos have been around for ages. They're fine, but where's the innovation? It's been a while since we've seen some big steps forward in the world of body decorations. But hell, flexible, implantable LEDs? Yeah, that's something new.
The LED arrays were developed by John Rogers from the University of Illinois at Urbana-Champaign, and they can twist and stretch by as much as 75%. Coated in thin silicon rubber, they're also waterproof and safe to implant under the skin. That means that you could, in theory, spell out your name in flashing lights under the skin of your back. I'd like to see a traditional tattoo do that.
