Women have been tattooing themselves as a form of expression for aeons, but new research may have just given them even more meaning. Scientists in MIT and Harvard University have created a subdermal smart tattoo that places health sensors in your skin to monitor any changes that can signify health hazards, no power or wireless link required.

“We were thinking: New technologies, what is the next generation after wearables? And so we came up with the idea that we could incorporate biosensors in the skin”, said Ali Yetisen, who is a Tosteson postdoctoral fellow at HMS and Massachusetts General Hospital.

The concept is still in its early stages, but at present, there’s talk of the colour-changing tattoo having the potential to warn you about medical emergencies, thanks to its ability to detect changes in your hydration and blood sugar levels. Inks developed so far change from green to brown as glucose concentration increases. 

New York Daily News reported that the advantages of smart tattoos include their use without electricity, their weightlessness, and their ability to work irrespective of skin changes.

You’re not stuck with it either. Scientists expect to make tattoos that only last for as long as you need them and they could even be invisible unless subjected to certain lights, so you wouldn’t have to do any explaining. Clever.
