Abstract:
This article described highly sensitive gas sensors for monitoring low ppm or ppb concentrations of carbon monoxide using phase variations at constant frequency of Love waves generated by a surface acoustic wave device. The sensing material for gas detection employed in this study is a silica layer modified with one of three compounds that assure a selective trapping of CO. The authors demonstrate that surface acoustic wave devices with non-conductive sensing layers as described can be used for molecular recognition such as to detect carbon monoxide molecules. This article reported an interest and original work.
