Zhao, C and Pandit, M and Sun, B and Sobreviela, G and Zou, X and Seshia, A (2017) A Closed-Loop Readout Configuration for Mode-Localized Resonant MEMS Sensors. Journal of Microelectromechanical Systems, 26. pp. 501-503.

This letter presents the first experimental results on the closed-loop characterization of a mode-localized microelectromechanical resonator system. Comparisons between the closed-loop oscillator approach and the open-loop frequency sweep approach show good agreement of output metrics including the amplitude ratios and mode frequencies. This new approach enables real-time measurements using emerging mode-localized resonant sensors and represents an important step toward realizing sensors based on this measurement principle.
