FLUCTUATION-ENHANCED GAS SENSING BY SURFACE ACOUSTIC WAVE DEVICES

This paper presents a new method for the detection, identification and quantitative analysis of gas molecules and their mixtures. The enhanced sensitivity and selectivity of this method allows the detection and identification of gases in amounts not previously detectable. This method is based on the spectral analysis of the dynamics of adsorbed molecules on surface acoustic wave (SAW) delay lines and resonators.
