发明名称 Uniaxial or biaxial microelectromechanical gyroscope with improved sensitivity to angular velocity detection
摘要 An integrated microelectromechanical structure is provided with: a driving mass, anchored to a substrate via elastic anchorage elements and moved in a plane with a driving movement; and a first sensing mass, suspended inside, and coupled to, the driving mass via elastic supporting elements so as to be fixed with respect to the driving mass in the driving movement and to perform a detection movement of rotation out of the plane in response to a first angular velocity; the elastic anchorage elements and the elastic supporting elements cause the detection movement to be decoupled from the driving movement. The elastic supporting elements are coupled to the first sensing mass at an end portion thereof, and the axis of rotation of the detection movement extends, within the first sensing mass, only through the end portion.
