In this paper a sensor phase space is introduced and the analysis of trajectories in this space is proposed as a method to evaluate the sensor response. The phase space gives the opportunity to introduce a novel feature describing the area spanned by the trajectory during adsorption and/or desorption of chemicals from the sensor. A comparison with the usual features resulted in a better accuracy and a shortest measurement time.

Abstract
In this paper a sensor phase space is introduced and the analysis of trajectories in this space is proposed as a method to evaluate the sensor response. The phase space gives the opportunity to introduce a novel feature describing the area spanned by the trajectory during adsorption and/or desorption of chemicals from the sensor. A comparison with the usual features resulted in a better accuracy and a shortest measurement time.File in questo prodotto:
