Graphene-coated fabrics detect dangerous gases
November 3rd, 2015
Scientists from the from the Electronics and Telecommunications Research Institute (ETRI) and Konkuk University in the Republic of Korea have developed wearable, graphene-coated fabrics that can detect dangerous gases present in the air, alerting the wearer by turning on an LED light. The researchers coated cotton and polyester yarn with a nanoglue called bovine serum […]
