A group of researchers from MIT and Harvard Medical School came up with an effective method to monitor different health conditions, while conforming to society’s beauty standards. Their idea involves keeping a close eye on one’s blood sugar or dehydration levels through biosensitive tattoos. These tattoos have a special ink which changes color when something’s wrong.
Biosensitive tattoos are better health monitors
This project is called Dermal Abyss, and consists of using special biosensitive ink when making tattoos. This ink contains special sensors which can detects the levels of sugar, sodium, or hydrogen in the fluids of the skin. When these levels change, the ink changes color, or turns more fluorescent.
These biosensitive tattoos can already make use of two different kinds of ink. Both of them are green, but one of them turns brown if blood glucose increases. The other one, when put under blue light, increases its intensity if the body increases its sodium levels. Researchers tested the ink on pig skin.
The biosensitive tattoos still need some improvements before they can be used as a full monitoring technique, but can still be more effective than most wearables. Since they are not battery-powered and don’t need a wireless connection to work, they are the best solution for people who need to be in constant watch of their health.
The changes are visible only in blue light
This is a great solution for athletes, who need to know every time when some change occurs in their body, or for astronauts, who also need to closely monitor their health. Also, they are most useful for diabetic people, as they can immediately see if they suffer sudden changes in their blood sugar levels.
Some people might think biosensitive tattoos are a bit intrusive if they display color changes in front of everyone. Researchers thought about this as well, and made the ink changes visible only in special blue light issued by a smartphone.
