Original Abstract

Quartz crystal microbalance (QCM) represents highly sensitive sensor for a detection of chemical substances. QCM-based gas sensors are widely utilized as a result of their robust nature, availability and affordable interface electronics. There are several mechanisms that are related to fluctuation phenomena. Generally, users require minimizing their impact on measurements in order to achieve maximal signal-to-noise ratio. However, fluctuation mechanisms can also give useful pieces of information about physical or chemical processes occurred in a sensor. The paper presents possibilities in enhanced sensing by using noise measurement of QCM. The experimental analysis was provided on polypyrrole-coated QCMs with a thin and a thick active layer.
