Abstract 

Combined temperature and humidity sensitive thick-film structures based on technological modified nanostructured ceramics (Cu0.1Ni0.1Co1.6Mn1.2O4 with p+-type of electrical conductivity, Cu0.1Ni0.8Co0.2Mn1.9O4 with p-type of electrical conductivity and magnesium aluminate i-type MgOAl2O3), as well as temperature-sensitive p-p+ and p-p+-p structures were prepared and studied. It is shown that increasing of the quantity of thick-film layers results in the improvement of the temperature sensitivity of thick-film structures. Humidity-sensitive thick films with temperaturesensitive films as conductive layers posses linear dependence of electrical resistance on relative humidity with hysteresis in the range of 30-95 %.
