Scientists at the Massachusetts Institute of Technology and Harvard Medical School have developed tattoos that measure blood levels. This invention could be very useful for people with diabetes. In these special tattoos the traditional ink has been replaced by a liquid containing biosensors that give information about the levels of blood sugar, sodium and pH. In this way the human skin becomes a kind of interactive display. The glucose biosensor changes from blue to brown when it detects a rise in blood sugar. A second sensor turns from pink to purple when there are variations in pH, and a third alerts you to an increase of sodium in the blood with intense fluorescent green tones.
This invention introduces a new and interesting field of exploration as these tattoos, in addition to being very useful to control diabetes, could potentially monitor other important measures of our health. This could improve the quality of life for children or adults with chronic diseases. It could also warn people about dehydration and other problems that are difficult to detect. The project is called DermalAbyss, and it is still in the testing stage, so there is no projected date for when it could be available to the public.
