This Stick-on Biosensor Monitors Blood Sugar—No Needle Necessary #WearableWednesday
There is promising news for people who have to monitor blood sugar levels. Via Gizmodo:
A new biosensor described in a paper published Wednesday in Science Advances suggests a workaround. Instead of a finger prick, an extremely thin, skin-like patch instead uses electrical signals to drive glucose out of nearby blood vessels to the skin’s surface to be measured. The whole thing is powered by a paper battery, and looks a little like a trendy temporary tattoo.
In a very small clinical trial of two healthy subjects and a third with diabetes, the device measured blood glucose levels almost as well as a standard clinical blood test during a five-day study. None of the patients reported any irritation or discomfort.
