Harvard, MIT boffins ink up with health-monitoring ‘smart’ tats

Oct 1, 2017

Researchers at Harvard and MIT have developed a subdermal ink capable of monitoring vitals such as hydration and blood sugar.

The team of eight researchers found that by mixing optical biosensors with tattoo ink, they are able to create tattoos (dubbed “dermal abyss” or “d-abyss”) that react with the body’s own fluids and change color when levels of substances such as sodium and glucose change.

“By featuring tissue cells with interactive properties, the skin can change its color, light intensity, or structure to display information. Hence, the skin cells become a pixel screen to be decoded by the user, other viewers, or cameras,” the researchers say.
