Abstract:
A yaw rate motion sensor, comprising:a driving element having a first axis for oscillating generally in a direction of the first axis upon application of a driving voltage; a sensing element for sensing a relative difference in a capacitance occasioned from the driving element upon application of a Coriolis force induced by an angular rotation; and linkage for translating a motion from the driving element to the sensing element; wherein the linkage is adapted for driving a driving mass of the driving element at a first natural frequency of the driving mass; wherein the linkage is adapted for driving a sensing mass of the sensing element at a natural frequency that is at about the same frequency as the first natural frequency of the driving mass; wherein the first natural frequency of the driving mass and the natural frequency of the sensing mass are selected to minimize feedback from the sensing element to the driving element.
