Researchers at MIT have developed color changing tattoos in an effort to save people from chronic diseases such as diabetes. People say it is like a mood ring. But, instead of color change occurring from a shift in mood, this tattoo changes colors to indicate low blood sugar levels.

They are now using a liquid with biosensors instead of ink; scientists want to turn the surface of the human skin into an “interactive display” so people with certain health problems that need to be monitored can get cool looking tattoos that have capabilities for tracking blood pressure and monitoring blood sugar level increases by the blue ink changing to a brown color.

Before this tech can be approved for human use, it will need to undergo more testing phases.

With the possibility of health-monitoring tattoos, it is exciting to contemplate what new medical advances will take place in the future.
