High-performance, tiny-mass sensors to measure particulate matter
Resonant mass sensors based on nanoelectromechanical systems (NEMS) have attracted a great deal of attention over the past two decades, most notably for their ability to weigh single molecules and nanoparticles, or even monitor the growth of living cells. Their performance is significantly compromised when they are exposed to ambient air – weight measurement can take a considerable amount of time. Funded by the Marie Skłodowska-Curie Actions programme, the MOSTAPDE project will address this challenge by combining thermal actuation and piezoresistive detection for NEMS-based resonators. This approach can significantly increase the quality factor at ambient conditions. The project plans to demonstrate how mass sensing can be applied to the measurement of particulate matter, which poses a significant threat to the environment.
