Imagine this: your phone rings and you lift your sleeve and push a tattooed button on your forearm. Next thing you know there is a digital video of the caller, moving in full video on your arm. After you hang up the tattoo completely fades away to leave nothing but your bare skin.
The Digital Tattoo Interface is a Bluetooth device that is inserted into the skin via a small incision. After inserted as a tube, it unrolls as a flat silicon base. It rests between skin and muscle. Glucose and oxygen in your blood fuel the implant via an attached artery and vein.
A special tattoo on the surface of your skin would interact with the field created by the device. Touching it through your skin would make it react similar to a touch screen display. Implications are limitless. Telephones, TV, the Web and just about everything else we rely on could be literally embedded in your skin.
This thing doesn’t actually exist but is a gadget design for a competition. I could exist. In the future. Just not now. 😉
