Diol and triol sensors and associated methods

Abstract

A sensor for sensing diols and triols includes (a) a substrate, (b) a conductive coating disposed on the substrate and having affinity for binding with a substance selected from the group consisting of diols, triols, and a combination thereof, and (c) two electrodes in contact with the conductive coating to probe conductivity of the conductive coating so as to detect the substance from a reduction in the conductivity. A method for detecting vaping includes (a) measuring conductivity of a conductive coating having affinity for binding with an airborne substance selected from the group consisting of diols, triols, and a combination thereof, and (b) detecting presence of the airborne substance as a decrease in the conductivity.
