I’ve been saying that the goal is not have as many wearables on our body as we can put on ourselves, but to measure vital signs and health parameters when we need it in a comfortable way. Here is a digital tattoo that can measure glucose levels. The proof-of-concept study was just published and it’s time to bring the era of wireless diabetes management to patients.
The thin, flexible device created by nanoengineers at UCSD is based on the much bulkierGlucoWatch, a now-discontinued wristband that worked through the same glucose-sucking principal. But the electric current GlucoWatch used to attract glucose to the surface of the skin was too high, and wearers were not keen on the discomfort. This temporary tattoo gets around the problem by using a gentler but still effective current.
