Researchers used sulfur dioxide as a model gas for testing the feasibility of developing a multicomponent sensor based on Surface Acoustic Wave (SAW) technology for the rapid identification and detection of ambient environmental gases in the sub-ppm to ppb range. Three different methods were examined in an attempt to impact SO2 specificity to several SAW devices: Chemical Bonded Adsorbents (CBA), Solvent Deposited Films, and Tungsten Trioxide (WO3). Results of the project are given. The major implication of the research will be the resulting merger of two existing technologies: metal oxide gas sensors (MEO) and surface acoustic wave devices (SAW).
