In this work the technology of receiving high-sensitivity gas sensors on the basis of zirconium oxide is developed for hybrid sensor systems. Laboratory samples of sensors of gas on the basis of zirconium oxide are made with use sol-gel method. Gas-sensitive characteristics of samples of sensors in relation to nitrogen dioxide are defined: limit of detection and factor of gas sensitivity. The received gas sensors will help to determine approach of an attack of bronchial asthma some hours prior to its beginning by level of an oxide of nitrogen in exhaled air of the person.
