    Abstract: The pressure sensor comprises a semiconductor material single crystal substrate (21); a semiconductor material layer (28) on the substrate (21); an air gap (55) arranged between the substrate (21) and the semiconductor material layer (28); and at least an opening (53) extending between the lower outer surface (52) of the substrate (21) and the air gap (55). The semiconductor material layer (28) is formed by a polycrystalline region (29) forming a diaphragm over the air gap (55) and by a monocrystalline region (30) elsewhere. Piezoresistive elements (46) extend over the semiconductor material layer (28), insulated therefrom by a dielectric layer (45), at a lateral delimitation edge of the diaphragm (29) and are connected one another so as to form a Wheatstone bridge the unbalancing whereof allows the pressure exerted onto the sensor to be measured.

    Abstract: The microreactor is completely integrated and is formed by a semiconductor body (2) having a surface (4) and housing at least one buried channel (3) accessible from the surface of the semiconductor body (2) through two trenches (21a, 21b). A heating element (10) extends above the surface (4) over the channel (3) and a resist region (18) extends above the heating element and defines an inlet reservoir and an outlet reservoir (19, 20). The reservoirs (19, 20) are connected to the trenches (21a, 21b) and have, in cross-section, a larger area than the trenches. The outlet reservoir (20) has a larger area than the inlet reservoir (19). A sensing electrode (12) extends above the surface (4) and inside the outlet reservoir (20).

    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.
