An Aerosol Sensor for Multi-Sized Particles Detection Based on Surface Acoustic Wave Resonator and Cascade Impactor

This research proposed the design, fabrication, and experiments of a surface acoustic wave resonator (SAWR)-based multi-sized particles monitor. A wide range selection and monitoring of large coarse particles (LCP), inhalable particles (PM<sub>10</sub>), and fine inhalable particles (PM&...

We verified the results of the particle diameter captured at each stage.
