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.
