| Abstract: | This paper is mainly introduce a novel gas sensor QCM (Quartz Crystal Microbalance), which has the characteristics of high sensitivity, high stability, and strong anti jamming ability. And it can be used in many fields. We study on the law of QCM responding to expiratory gases. Using a computational chemistry method, we can easily design sensitive film of sensor, and make it by the electropolymerization theory. We also design a measurement systems and use a IEEE488 card to connect measurement equipment. And we get the response data of expiratory gases from the QCM gas sensor. So we have the conclusion that the QCM gas sensor can be used in measuring acetone gas in breath. |
