On the statistical analysis of noise in chemical sensors and its application for sensing Academic Article uri icon


  • Resistance noise data from a single gas sensor can be utilized to identify gas mixtures. We calculated the power spectral density. higher order probability densities and the bispectrum function of the recorded noise samples; these functions are sensitive to different natural vapors and can be employed to select a proper detection criterion for gas composites and odors.
