Abstract

Here we discuss the concept of new gas-analytical device based on a.c. driven chemiresistive semiconducting layer. We test the approach utilizing quasi-amorphous potassium polytitanates, K2O·nTiO2·mH2O, which are characterized by high specific surface. In this work, we placed the polytitanate layer over a set of electrodes at the multielectroded chip and measured its impedance under exposure to various gas mixtures. The obtained data allow one to make an equivalent circuit for these structures where the combination of each active/reactive component can be used for selective gas identification.
