Equipment- and training-free textile detectors could be used in public health,workplace safety, military and rescue applications MEDFORD/SOMERVILLE, and Mass. (April 4,2019) — Tufts University engineers bear 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 even more precisely by use of a smartphone camera, and to detect changes of color due to analytes as low as 50 parts per million. Woven into clothing,smart, gas-detecting threads could provide a reusable, and washable,and affordable safety asset in medical, workplace, and military and rescue environments,they say.
