Abstract: Resonant microcantilever is a mass-type sensor that transforms mass change into frequency-shift signals. Due to the advantages of high mass resolution, high sensitivity, low cost, easy integration and miniaturization, resonant microcantilevers have received extensive attention from researchers. In recent years, with the rapid development of MEMS (Micro-Electro-Mechanical Systems) technology, resonant micro-cantilever sensors have been widely used in mass and flow control, trace biomedical detection, gas or liquid molecular analysis and other broad application fields. Herein, the specific applications of resonant microcantilever sensors in environmental detection, biomedicine and other fields in recent years are reviewed, and the future development trends are prospected.
