✦ Synopsis

The AC equivalent circuits of thick film humidity sensors are presented. The active layers are based on ZnO-TiO,-Cr,O, ceramics. The compositions contain L&O, B,O, and Si additives. Using the impedance spectroscopy analysis it is possible to construct equivalent circuits of sensors. Elements of these circuits represent the different conduction and polarisation mechanisms existing in the analysed sensors. The influence of technological and construction parameters on electrical properties of sensors can be evaluated as well.
