Cover Story: The detection of ultrafine particulates produced by combustion engines and other sources is of significant interest to assessing ambient air quality and supporting related epidemiological studies. In this paper, weakly-coupled piezoelectric MEMS resonators are configured as high-resolution gravimetric sensors for the detection of ultrafine particulates. As a proof-of-principle, this paper experimentally demonstrates the application of these MEMS devices to the detection of diesel soot particles of approximately 100 nm diameter. The MEMS sensors employed in this work operate on the principle of vibration mode-localization, employing an amplitude ratio readout metric. Notably, gains in parametric sensitivity and output stability are obtained based on this approach, demonstrating suitability for long-term measurements. View this paper.
