MEMS device having distance stops
摘要:
A micro-electromechanical systems (MEMS) device includes bottom and top capacitive plates, such that a capacitor is definable therebetween. A mechanism is electrostatically movably disposed between the bottom and top capacitive plates. One or more flexures are movably disposed between the bottom capacitive plate and the mechanism, and having distance stops between the bottom capacitive plate and the mechanism corresponding to maximum downward movement. The MEMS device includes one or more electrodes of the bottom capacitive plate corresponding to the flexures. Energizing different of the electrodes causes the flexures to move to different of the distance stops, causing the mechanism to move to different positions between the bottom and top capacitive plates.
