Actually, I admittedly don’t have any tattoos or piercings. 90s alterna-culture cured me of ever wanting either of those, which I guess shows you how much of a contrarian pain in the ass I can be.

Anyway, this tattoo is cool as all hell: a subcutaneous working cell phone powered by your own blood. Now that’s f*&king science, people!!

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.
