Skin Patch Monitors Blood Glucose Through Sweat

Oct-15-16 A new wearable for diabetics monitors blood glucose levels via the sweat on skin, offering an end to daily needle pricks.

Developed by a team at the University of Texas, the inch-long, skin-worn biosensor is made of a commercially available polymer-based textile, and uses the same general chemistry found in blood glucose testing strips. To enable the sensor to detect the glucose in a small amount of sweat, the team arranged the electrodes so that the sweat spreads evenly through the textile. The team also designed the material so that it will trap glucose oxidase molecules, enhancing the signal of the chemical reaction.
