Abstract
Micromachined inertial devices are presented having multiple linearly-moving masses coupled together by couplers that move in a linear fashion when the coupled masses exhibit linear anti-phase motion. Some of the described couplers are flexural and provide two degrees of freedom of motion of the coupled masses. Some such couplers are positioned between the coupled masses. Using multiple couplers which are arranged to move in linearly opposite directions during linear anti-phase motion of the coupled masses provides momentum-balanced operation.
