Welcome to the conceptual solution that combines the beauty of a tattoo with the convenience of your cell phone and Bluetooth technology, the “Digital Tattoo Interface.” DTI, developed by Jim Mielke, debuted at this year’s Greener Gadgets Design Competition 2008, receiving Notable Entry award. This is one tattoo with a lot of potential: a phone that would be implanted under the skin, with microscopic spheres that would act as the touch-screen buttons. Don’t want to show off your phone? The concept has a button that, when pushed, can render the phone invisible. If you get a call, just push the same button to answer the display and have the phone reappear, with video capability.
Where’s the battery? There isn’t one. You just eat something (preferably food), and the phone works off your own blood supply. With luck this phone quickly moves on from concept to actuality for a fashionable future enhancement.
