Response Curve Modeling of Chemiresistive Gas Sensors by Modified Gompertz Functions

A considerable multitude of chemiresistive type of gas sensors has been estimated to sense minute amounts of hazardous or toxic gases using inexpensive setups. Although the ultimate value of the response of gas sensors is well-established, analyzing other characteristics has been mostly neglected. In the present paper, we demonstrate the modeling of time-dependent responses by slightly modified Gompertz functions whose derived parameters can be correlated with the detection mechanism, thus, expanding analysis methods towards a better understanding of gas sensing.
