Abstract Air-microfluidics encompasses the use of micro electro mechanical systems (MEMS) to develop low-cost/small footprint lab-on-a-chip devices for air quality monitoring. This poster reviews the recent advances in MEMS low-cost environmental sensors. In particular, we describe latest results from theoretical and experimental comparison between different implementations of gravimetric direct-read MEMS airborne particulate matter (PM) sensors developed in our lab. We show that the sensitivity ad stability of the sensor is fundamentally dependent on the design of the mass-sensing resonator, as well as the driving circuitry. We describe the figures of merit of this new and emerging technology, and show examples of successful implementation of this technology in several types of direct-reading PM mass sensors developed in our lab.
