Abstract
An integrated gyroscope, including an acceleration sensor formed by: a driving assembly; a sensitive mass extending in at least one first and second directions and being moved by the driving assembly in the first direction; and by a capacitive sensing electrode, facing the sensitive mass. The acceleration sensor has an rotation axis parallel to the second direction, and the sensitive mass is sensitive to forces acting in a third direction perpendicular to the other directions. The capacitive sensing electrode is formed by a conductive material region extending underneath the sensitive mass and spaced therefrom by an air gap.
