Wearable, Non-Invasive Sensor Measures Glucose in Sweat

Scientists at Penn State University developed a wearable glucose monitor that can non-invasively measure glucose levels within sweat in real time. The low-cost sensor consists of laser-induced graphene and a nickel-gold alloy that can detect the very low levels of glucose in sweat without the use of enzymes. The sensor contains a microfluidic chamber into which sweat is drawn, and then an alkaline solution reacts with the glucose in the sweat, causing a reaction in the alloy and a substantial electrical signal.
