Having type 1 or 2 diabetes requires a person to always know what their blood sugar levels are. This normally takes time and can be quite invasive – normally people prick their finger with a special device and place a small drop of blood on a testing strip.
Others have a device implanted just under their skin that continuously measures their blood sugar levels and sends the information to an external device.
A team of researchers at Harvard and MIT have now come up with a rather curious alternative. Using a specialized ink, they have come up with a biosensing tattoo, one that will change color depending on your blood sugar levels.
Known as DermalAbyss ink – currently still in the proof-of-concept stage and not available to the general public – it is able to track pH levels, as well as sodium and glucose concentrations within your bloodstream. Too much glucose and the ink becomes brown. Too much sodium and it becomes green (under UV light, at least). Purples and pinks indicate a changing pH level.
