Paper Abstract

A chemical sensor system based on arrays of surface acoustic wave (SAW) delay lines has been developed for identification and quantification of volatile organic compounds. The individual SAW chemical sensors consist of interdigital transducers patterned on the surface of an ST-cut quartz substrate to launch and detect the acoustic waves and a thin film coating in the SAW propagation path to perturb the acoustic wave velocity and attenuation during analyte sorption.
