Optimised dynamic temperature operating mode specifically dedicated to micromachined SnO2 gas sensors

Abstract : In this paper, we show the influence of short temperature variations on the transient response of a SnO2 nanoparticular gas sensor. By consideration of the shape and time constants of the normalized response curves, we can differentiate different gasses mixtures at a ppm level. This new method of analysis is promising to conceive a gas detector based on combination of temperature profiles and different sensitive layers.
