First protection: Smart fabric SOFT can detect and alert toxic gases

Scientists at Dartmouth College in New Hampshire are reportedly developing a smart Fabric that detects the presence of dangerous gases and protects the wearer from poisonous gases. This material, called SOFT, is highly malleable and conductive, and also has permeability and washfastness.

Researchers at Dartmouth College say the material is capable of detecting the presence of toxic gases in real time. Researchers envision using this material to create protective clothing for the military and emergency services as the first protection for users.

Katherine Mirica, an associate professor of chemistry at Dartmouth College, said: "By adding this material to protective clothing, when a chemical comes into contact with a protective suit, the sensor warns the user. It is not just passive protection. When the protective suit is torn or has a loophole, it can also proactively alert."

This smart fabric relies on an electronic sensor that supports textiles, which is what we often call metal organic frameworks (MOFs). In their research, the research team showed that this material can identify nitric oxide gas and corrosive toxic hydrogen sulfide gas in pollutants. Researchers claim that this material not only detects these gases, but also captures and filters toxins from toxic gases.

Although this technology requires further research before it can be applied to wearable systems, researchers believe that this manufacturing method is likely to extend to other systems to create a series of new smart textiles with adjustable characteristics.
