Separating Chemical Signals of Adsorption– Desorption and Diffusive Processes Academic Article uri icon

abstract

  • We present a new sensor signal processing method that improves selectivity, sensitivity, and processing speed in systems, using fluctuation-enhanced sensing. We consider the output signal of a symmetric two-sensor arrangement and generate two independent output spectra by separating the adsorption-desorption signal component from the diffusion signal component. We demonstrate the key features of our method by computer modeling and simulation. © 2010, IEEE.
