ABSTRACT:
A gyro sensor configured to sense an angular rate about a rotational axis includes a drive mass configured to undergo oscillatory linear motion within a plane, and a sense mass configured to undergo an oscillatory motion out of the plane as a function of the angular rate. A link spring component connects the sense mass to the drive mass such that the sense mass is substantially decoupled from the drive mass with respect to the oscillatory linear motion of the drive mass, but is coupled to the drive mass with respect to the oscillatory motion out of the plane of the sense mass.
