A biosensor bandage able to collect and analyze sweat could offer an affordable alternative to blood samples.
Developed by researchers from the US and China, the wearable device is made up of a flexible polymer film coated with a super-hydrophobic silica suspension etched with microwells. Color-changing dyes are placed at the bottom of the wells, where they will react to changes in pH, chloride, glucose or calcium. The patch adheres to the skin, where sweat trapped in the micropores will trigger the dye spots to change color based on the chemical makeup of the liquid.
