We’ve seen a few examples of wearable materials that indicate the presence of hazardous substances, like these color-changing gloves. Now, a team of researchers at Konkuk University in South Korea have created an extremely sensitive fabric that detects noxious gases. By coating cotton fibers with a nanoglue, the team were able to wrap textiles in graphene — a single-atom carbon known for its extreme durability and conductivity. The graphene’s conductivity changes in the presence of certain gases, and the team found the fabric to be very sensitive to the nitrogen-based gases present in smoggy air pollution. The commercialization of the…
