A load compensation device may include an assisted joint configured to be constrained to a support structure; a main rod comprising a proximal end connected to the assisted joint, and further comprising a distal end configured to be stressed by an applied load; an auxiliary rod comprising a first end and a second end, the first end being hinged on the main rod for rotating the auxiliary rod with respect to the main rod, the second end being movable on a plane on which the applied load lies; an elastic element configured to provide an elastic force which acts between the second end of the auxiliary rod and the distal end of the main rod; a regulation system configured to modify a distance between the second end of the auxiliary rod and the assisted joint, so as to vary a preloading of the elastic element.

Load compensation device, in particular of gravitational loads, applicable to exoskeletons

Braking device inserted in a test bench () for checking the correct operation of industrial screwdrivers, wherein the braking simulates a tightening operation of such screwdriver, comprising a container body () on the top of which a coupling () protrudes, suitable for coupling with the head () of the screwdriver to be tested, said coupling () being connected, by means of a shaft (), to a braking unit (), an electronic torque and angle detector () of the shaft rotation (). Such braking unit () comprises a plate (), rotated by the screwdriver, which is braked by suitable friction surfaces () moved towards the plate by the movement of an actuator; the movement of such actuator is performed by means of at least one electronically controlled piezoelectric element ().

A microelectromechanical transducer includes a semiconductor body having first and second surfaces opposite to one another. A plurality of trenches extend in the semiconductor body from the first surface towards the second surface, including a first pair of trenches having a respective main direction of extension along a first axis, and a second pair of trenches having a respective main direction of extension along a second axis orthogonal to the first axis. A first piezoresistive sensor and a second piezoresistive sensor extend at the first surface of the semiconductor body respectively arranged between the first and second pair of trenches. The first piezoresistive sensor, the second piezoresistive sensor and the plurality of trenches form an active region. A first structural body is mechanically coupled to the first surface of the semiconductor body to form a first sealed cavity which encloses the active region.

A microelectromechanical force/pressure sensor has: a sensor die, of semiconductor material, having a front surface and a bottom surface, extending in a horizontal plane, and made of a compact bulk region having a thickness along a vertical direction, transverse to the horizontal plane; piezoresistive elements, integrated in the bulk region of the sensor die, at the front surface thereof; and a cap die, coupled above the sensor die, covering the piezoresistive elements, having a respective front surface and bottom surface, opposite to each other along the vertical direction, the bottom surface facing the front surface of the sensor die. A conversion layer is arranged between the front surface of the sensor die and the bottom surface of the cap die, patterned to define a groove traversing its entire thickness along the vertical direction; the piezoresistive elements are arranged vertically in correspondence to the groove and the conversion layer is designed to convert a load applied to the front surface of the cap die and/or bottom surface of the sensor die along the vertical direction into a planar stress distribution at the groove, acting in the horizontal plane.

A MEMS gyroscope is equipped with: at least a first mobile mass suspended from the top of a substrate by means of elastic suspension elements coupled to anchor points rigidly fixed to the substrate, in such a manner as to be actuated in an actuating movement along a first axis of a horizontal plane and to carry out a measurement movement along a vertical axis, transverse to the horizontal plane, in response to a first angular velocity acting about a second axis of the horizontal plane, transverse to the first axis. The elastic suspension elements are configured in such a manner as to internally compensate unwanted displacements out of the horizontal plane along the vertical axis originating from the actuating movement, such that the mobile mass remains in the horizontal plane during the actuating movement.
