Quality factor control of mechanical resonators using variable phononic bandgap on periodic microstructures

open access: yesScientific Reports, 2022
The quality factor (Q-factor) is an important parameter for mechanical resonant sensors, and the optimal values depend on its application. Therefore, Q-factor control is essential for microelectromechanical systems (MEMS).

Air Damping Analysis of a Micro-Coriolis Mass Flow Sensor

open access: yesSensors, 2022
A micro-Coriolis mass flow sensor is a resonating device that measures small mass flows of fluid. A large vibration amplitude is desired as the Coriolis forces due to mass flow and, accordingly, the signal-to-noise ratio, are directly proportional to the
