That’s “sew” smart! Scientists invent threads to detect gases when woven into clothing

Engineers have developed a novel fabrication method to create dyed threads that change color when they detect a variety of gases. The researchers demonstrated that the threads can be read visually or by use of a smartphone camera to detect changes of color due to analytes as low as 50 parts per million. These gas-detecting threads could be used in medical, workplace, military, and rescue environments.
