    Abstract: The gyroscope (1) is formed by a driving system (16) including a driving mass (5) having an open concave shape; an accelerometer including a sensing mass (6) and comprising mobile sensing electrodes (18); a linkage (24) connecting the driving mass (5) to the sensing mass (6). The sensing mass is surrounded on three sides by the driving mass and has a peripheral portion not facing the sensing mass. The mobile sensing electrodes (18) extend integral with the sensing mass from the peripheral portion not facing the driving mass (5) and are interleaved with fixed sensing electrodes (19a, 19b). Thereby, there are no passing electrical connections extending below the sensing mass (6). Moreover the linkage includes springs (24) placed equidistant from the center of gravity (G2) of the accelerometer, and the gyroscope (1) is anchored to the substrate with anchoring springs (10) placed equidistant from the center of gravity (G1) of the assembly formed by the driving system (16) and by the accelerometer (23).
