Everyone and their mother has a tattoo these days, but in the future your ink stains may be more than a daily reminder of that wild week you spent in Cabo.

A team of researchers at MIT Media Labs is developing the Dermal Abyss, an ink that turns tattoos into a biosensor interface. Rather than using traditional tattoo inks, the fluids used by the MIT researchers change colors in response to changes in interstitial fluid, or the stuff that surrounds tissue cells in the body.

Despite its unsettling name, Dermal Abyss is both aesthetically pleasing and potentially a game changing technology for people with illnesses that require constant monitoring, such as diabetics.

Rather than using traditional tattoo inks, the fluids used by the MIT researchers are biosensors. These are liquids that change colors in response to changes in interstitial fluid, the stuff that surrounds tissue cells in the body.
