Whether or not you like tattoos (or have one yourself), you’ll have to admit—these are pretty cool. Scientists have developed something called a “biosensing” tattoo that could help change the lives of people living with types 1 or 2 diabetes. How could a tattoo do this, you ask? Well, by changing color along with the person’s blood sugar levels.
This new tattoo is the hard work of a team of researchers from Harvard and MIT who call the project Dermal Abyss. The researchers replaced traditional tattoo ink with color-changing “biosensors” that react to variations in the interstitial fluid, which surrounds tissue cells in the human body.
“It blends advances in biotechnology with traditional methods in tattoo artistry,” the team writes on their website. “Currently… diabetics need to monitor their glucose levels by piercing the skin, 3 to 10 times per day. With Dermal Abyss, we imagine the future where the painful procedure is replaced with a tattoo. Thus, the user could monitor the color changes and the need of insulin.”
