    Abstract: The bi-dimensional position sensor (1) can be advantageously used in the turn system controlled from the steering wheel of a vehicle and comprises a permanent magnet (3) fixed to a control lever (4) so as to move in a plane along a first (X) and a second (Y) direction and rotate about a third direction (W) orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device comprising a first group of sensor elements (10 1 -10 3 ) arranged spaced along the first direction, a second group of sensor elements (10 4 -10 7 ) arranged spaced along the second direction and a third group of sensor elements (10 8 -10 9 ) detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet (3) may assume and a control signal (S) corresponding to the desired function.

    Abstract: In a micro-electromechanical structure, in particular an accelerometer (1;30;60), a movable mass or rotor (4;34;61) has a centroidal axis (G;G') and includes a suspended structure (8;38;62) which carries mobile electrodes (10;40). A stator (5;35;77) carries fixed electrodes (12;42) facing the mobile electrodes. The suspended structure (4;34;61) is connected to a rotor-anchoring region (16;44) via elastic elements (15;45;65). The stator includes at least one stator element (20;55;67),which carries a plurality of fixed electrodes (12;42) and is fixed to a stator-anchoring region (21;54). One of the rotor-anchoring regions and stator-anchoring regions extends along the centroidal axis (G;G') which is an axis perpendicular to the plane of the structure, through its centre of gravity, and at least another of the rotor-anchoring regions and stator-anchoring regions extends in the proximity of the centroidal axis (G;G'). Due to the small distance of all anchoring regions to each other, and to the centre of gravity, stresses due to thermal mismatches can be reduced.
