A touch screen tattoo that is fueled by your blood
It looks like that future we have heard about has arrived. At the Greener Gadgets Conference in New York, there was a Bluetooth enabled touch screen that is designed to be inserted between the skin and the muscle. That’s right, an animated and interactive tattoo. But that is not the awesome part.
The basis of the 2×4-inch “Digital Tattoo Interface” is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.
It runs off energy from your blood. How cool is that.
