The future of tattoos could give you a life-saving warning when your blood sugar dips.

People get tattoos for decorative or commemorative reasons, but now teams at MIT Media Lab and Harvard Medical School have collaborated to give tattoos a new function: delivering real-time data about your body. The researchers have created a tattoo ink that reacts to your body’s chemistry to change colors as your body changes.

Called DermalAbyss, the work is the brainchild of MIT Media Lab researcher Katia Vega, who worked with Harvard Medical School to create four types of biosensors that react to three types of biochemical information. These unconventional inks inject biosensors below the skin to gather measurements on interstitial fluid in your skin and change in color when glucose (blue and brown scale), sodium (varying intensities of fluorescence) or pH levels (purple and pink scale) change in your body.

The biosensors have been tested on an ex vivo pig skin model.
