Abstract
This paper demonstrates the feasibility of employing mode localized mass sensing in coupled MEMS resonators for ultra-fine particulate detection applications. The potential benefits of this approach include higher parametric sensitivity and intrinsic common mode rejection as compared to the resonant frequency shift-based detection approach. Weakly coupled MEMS resonators demonstrated in this paper demonstrate sensitivity to fine particulates and a significant improvement in mass sensitivity for particulate quantification by employing an amplitude ratio shift output metric.
