Summary:Engineering A smart adhesive patch that wicks sweat away from electronics embedded in its centre offers comfortable and reliable sensing of the wearer's biometrics or environment without the risk of perspiration damaging the devices. Human skin is a remarkable organ that can regulate body temperature by secreting sweat that then evaporates. The authors began their fabrication process by immersing a polyester fabric in a suspension that made it superhydrophobic, and then dip-coated one side of the fabric with a water-based adhesive.
