Scientists from Massachusetts institute of technologies (MIT) and Harvard Medical School have developed unique biosensing ink within the Dermal Abyss scientific project. Tattoos made by this ink allow to monitor health condition of a person.
Currently, they are only responding to changes in the body’s metabolism. As soon as the indicator reaches a critical level, tattoos inform owners, changing their color.
Scientists believe that in future bio tattoos will be able to monitor other health features, replacing modern fitness bracelets and other gadgets.
But there is also one ethical issue. It is still unclear whether people will want to show others a condition of their body.
