  • Patent number: 8042394
    Abstract: A driving mass of an integrated microelectromechanical structure is moved with a rotary motion about an axis of rotation, and a sensing mass is connected to the driving mass via elastic supporting elements so as to perform a detection movement in the presence of an external stress. The driving mass is anchored to an anchorage arranged along the axis of rotation by elastic anchorage elements. An opening is provided within the driving mass and the sensing mass is arranged within the opening. The elastic supporting and anchorage elements render the sensing mass fixed to the driving mass in the rotary motion, and substantially decoupled from the driving mass in the detection movement. The detection movement is a rotation about an axis lying in a plane. The sensing mass has, in plan view, a non-rectangular shape; in particular, the sensing mass has a radial geometry and, in plan view, the overall shape of a radial annulus sector.

  • Patent number: 8042396
    Abstract: A driving mass of an integrated microelectromechanical structure is moved with a rotary motion about an axis of rotation, and a sensing mass is connected to the driving mass via elastic supporting elements so as to perform a detection movement in the presence of an external stress. The driving mass is anchored to a first anchorage arranged along the axis of rotation by first elastic anchorage elements. The driving mass is also coupled to a pair of further anchorages positioned externally thereof and coupled to opposite sides with respect to the first anchorage by further elastic anchorage elements; the elastic supporting elements and the first and further elastic anchorage elements render the driving mass fixed to the first sensing mass in the rotary motion, and substantially decoupled from the sensing mass in the detection movement, the detection movement being a rotation about an axis lying in a plane.

  • Patent number: 7694563
    Abstract: A driving mass of an integrated microelectromechanical structure is moved with a rotary motion about an axis of rotation, and a first sensing mass is connected to the driving mass via elastic supporting elements so as to perform a first detection movement in a presence of a first external stress. The driving mass is anchored to an anchorage arranged along the axis of rotation by elastic anchorage elements. An opening is provided within the driving mass and the first sensing mass is arranged within the opening. The elastic supporting and anchorage elements render the first sensing mass fixed to the driving mass in the rotary motion, and substantially decoupled from the driving mass in the first detection movement. A second sensing mass is connected to the driving mass so as to perform a second detection movement in a presence of a second external stress. A first movement is a rotation about an axis lying in a plane, and a second movement is a linear movement along an axis of the plane.
