Recent progress on mass-sensitive gas sensors for environmental and industrial applications

Abstract

In the past ten years, the technology of mass-sensitive gas sensors has seen significant progress, becoming essential in areas such as environmental monitoring and industrial safety. This extensive review explores the latest developments in this field, particularly focusing on microcantilevers, surface acoustic wave (SAW) sensors, and quartz crystal microbalance (QCM) sensors, along with the sensing materials crucial for their operation. The review discusses different parameters that affect the performance of mass sensitive gas sensors, such as sensitivity, selectivity, and stability. The utilization of novel sensing materials for targeted selective adsorption of gases improves sensor performance. We hope that this review will be a useful resource for those seeking to quickly find relevant literature on mass-sensitive gas sensors.
