Tilt dynamics of an electrostatically actuated microoscillator at a liquid-liquid interface

"We investigate the time-domain tilt response of an electrostatically actuated mechanical microoscillator positioned at a liquid-liquid interface. An analytical model is presented to simulate the microoscillator’s rotational motion inside a microchannel completely filled with two immiscible liqu...
