Analysis of kinetic dependencies of the response of a gas sensor based on a model of a stretched exponential function with the use of computer technologies

Abstract

The results of improving the software of an information measuring system for studying relaxation phenomena in various objects based on a model of a stretched exponential function by supplementing it with intelligent components that eliminate operator participation are present.
A variant of the implementation of such computer processing of experimental relaxation dependencies is presented, which makes it possible to implement the choice of
- the most informative time interval from the entire measurement time range for the processed kinetic dependencies in order to most accurately estimate all model parameters;
- optimal analytical expressions for representing trends in the influence of one or another specified external factor on the parameters of the specified function.
The proposed algorithm and its software implementation are used to process research data on gas-sensitive sensor materials. The results of the testing of the developed application showed satisfactory correspondence of the obtained results to the existing physical concepts and allowed us to conclude that this approach is promising for automating the processing and analysis of experimental relaxation dependencies.
