This paper presents flexible humidity sorption sensors, its construction and impedance measurement results. Based on the obtained results and models applied to various humidity sensors, a model with two resistors and two constant phase elements is chosen as the most appropriate. Fitting procedure is described and its results are presented. The dependence of model parameters on relative humidity is discussed and conclusions on model applicability are drawn.
This paper presents humidity sorption sensors with eight different polymer coatings. After the introduction of sensor construction, a presentation of tested sorption laters and measurement system is provided. Finally, the results are presented and discussed as well as validation tests are described. Two most suitable coatings are chosen.
