Abstract

Using the methods of liquid deposition the operating laboratory models of humidity sensors with a functional layer based on Alginate biopolymer and ZrO2 – 3mol%Y2O3 nanopowder of particles size 7.5, 12 and 35 nanometers were obtained. Their electrical properties were investigated on a direct current mode under the conditions of dynamic changes of the atmospheric humidity. The threshold of percolation of electric properties of the studied metal-oxide nanostructured systems in the conditions of gas-phase adsorption equilibrium was established. It was shown a possibility of using of the specified nanodimensional systems for the development of non-volatile humidity sensors for the needs of a bionanoelectronics and modern sensory.
