Abstract
In this work we will summarize over a decade’s worth of work on the research conducted at the Air-Microfluidics Group (AMFG) on developing air-microfluidic resonator-based real-time gravimetric PM mass sensors. The applications developed used microelectromechanical systems (MEMS) technologies to fractionate and deposit aerosols onto acoustic resonators. We present the advantages and pitfalls of using these approaches for measuring concentrations of airborne PM at various sizes in handheld applications, in particular compared to optical detection methods. We will then present our most recent work, developing gravimetric MEMS PM sensors using 2-photon stereolithography, and show their applications to novel types of optimized low-cost MEMS aerosol sensors.
