Abstract: Planar vibratory gyroscope structures are provided which are inherently symmetric, which facilitate the use of simple monolithic fabrication processes and which enable the use of sensitive control and sense systems. A planar vibratory member of these structures has a hollow frame, a plate that has a plate perimeter and is positioned within the frame and a plurality of elongate beams which couple the plate to the frame wherein each of the beams is proximate to and substantially parallel to a respective portion of the plate perimeter. The exterior rim of the planar member can be supported by a substrate which provides room for easy access to the plate with mode control and sense systems.
