Researchers develop moisture-resistant, stretchable NOx gas sensors based on laser-induced graphene

Researchers from Penn State and China’s Hebei University of Technology, as well as additional collaborators from China, have developed a new water-resistant gas sensor for accurate, continuous monitoring of nitrogen dioxide and other gases in humid environments.

The new water-resistant gas sensor can be worn under the nose to detect nitrogen dioxide in the breath, the concentration of which may indicate potential pulmonary diseases.
