. "26220" . "Quartz crystal microbalance belongs to a group of high-sensitive chemical sensors for detection of substances dispersed or dissolved in gas or liquid environments. Several equivalent circuits exist for the QCM sensor. Design of these circuits depends mainly on an active layer of sensor as well as on an environment, in which a sensor is applied. An equivalent circuit is usually separated in two parts; the first one corresponds to quartz crystal, while the second part relates to chemical and physical properties, such as concentration of detected matter, viscosity of an active layer, viscosity of environment, etc.. For design of driven-oscillator circuit of QCM, it is necessary to develop accurate equivalent circuit, which is able to simulate behavior of QCM for a large range of concentration of detected matter. In the paper, the study is provided on polypyrrole-based QCM. Polypyrrole is suitable material for humidity measurements, and was deposited by matrix assisted pulsed laser evaporation technique" .
