South Korea’s Institute for Basic Science (IBS) has developed a wearable graphene-based armband which is capable of monitoring diabetes by analysing the sweat of the wearer. The patch is made up of electrochemically active materials on a hybrid of gold-doped graphene and a serpentine-shape gold mesh. As IBS’s Kim Dae-Hyeong explains, the “device is capable of not only sweat-based glucose and pH monitoring, but also controlled transcutaneous drug delivery through temperature-responsive microneedles.”
