Researchers at the Massachusetts Institute of Technology (MIT) and Harvard Medical School have teamed to develop a novel tattoo ink that can show your body’s health changes.
The novel ink consists of biosensors that react to changes in the tissue fluid and make the skin an “interactive display”. So far, researchers have investigated four biosensors that respond to three types of body information, changing their colors.
As the pH-value increases, the color changes from violet to pink, an increasing sodium content is seen as a bright green under UV light, and blue becomes brown when the glucose level increases.
This animation from a video of the researchers shows how such a tattoo might look like:
Especially for diabetics, a tattoo with ink that reacts to an altered glucose level could be useful. They have to prick their finger with a small needle if they want to measure their blood sugar level – usually several times a day. This procedure can be painful in the long run and can lead to small scars.
