Electronic Theses and Dissertations
The growing concerns regarding atmospheric toxins and their detrimental effects on life establishes the necessity to identify and monitor them. Environmental monitoring demonstrates an effective method to controlling the impact of atmospheric pollutants using gas sensors. The Quartz Crystal Microbalance (QCM) is one such device which has been widely used for detecting microgram level mass changes in gas and liquid phase. In this research a novel approach to designing QCM electrode configurations based on distributing the mass loading area to improve the mass sensitivity is proposed. Conventional QCM designs comprise a circular electrode configuration with an evenly distributed mass loading …
