10/4/2012· For a QCM sensor, the selectivity is determined by the sensing film material. Therefore, the key challenge for a QCM gas sensor is how to adopt an appropriate sensing film material for the analyte to be detected. In order to improve the selectivity of QCM sensors, various sensing materials have been investigated [7,9,14–18].
