Low Cost Wearable Nitrogen Dioxide Sensor
July 26, 2022 | Terry Sharrer
“The surge in air pollution and respiratory diseases across the globe has spurred significant interest in the development of flexible gas sensors prepared by low-cost and scalable fabrication methods. However, the limited breathability in the commonly used substrate materials reduces the exchange of air and moisture to result in irritation and a low level of comfort. This study [from engineers at Hebei University of Technology, Tianjin, China] presents the design and demonstration of a breathable, flexible, and highly sensitive NO2 gas sensor based on the silver (Ag)-decorated laser-induced graphene (LIG) foam.” MORE
