ABSTRACT:
A gap-closing actuator includes a stator having one or more first electrodes, a mover having one or more second electrodes interposed among the first electrodes, and a biasing mechanism for applying a non-capacitive bias to the mover for urging the mover to move in a desired direction with respect to the stator. The non-capacitive bias is different from a capacitive force generated between the first and second electrodes when the gap-closing actuator is in operation.
