Abstract
A microelectromechanical gyroscope that comprises two seismic masses suspended to form a plane of masses. The seismic masses are excited into rotary oscillation about a common primary axis that is in the plane of masses. Detected angular motion causes a rotary oscillation of the first seismic mass about a first detection axis, and of the second seismic mass about a second detection axis. The detection axes are perpendicular to the plane of masses and separated by a non-zero distance.
