Abstract: The ultrasonic tubular transducer is activated at the centre thereof by two symmetrical electromechanical converters. The vibration generated by the two electromechanical converters is converted and then transmitted to the tube via a coupler. The ultrasonic transducer can be vibrationally isolated from the interfaces thereof by caps equally suitable for connecting the transducer to a stationary frame, a free end or another similar ultrasonic transducer. A device for pre-stressing electromechanical converters has a hole bored at the centre thereof in order to allow cables from the transducer as well as from adjacent transducers to pass therethrough.

Abstract: A piezoelectric device comprises a fixed frame and a mirror carrier defining several support points securing a mirror. The mirror carrier is mounted rotatable. Several piezoelectric actuators are fixed to the support and deform independently in translation in a first direction. Each piezoelectric actuator moves the support area of the mirror carrier. The mirror carrier defines several attachment points. Each attachment point connects the mirror carrier mechanically with a piezoelectric actuator. The support points and attachment points are distinct from one another. The mirror carrier defines a plurality of flexion areas. The support points are movable with respect to one another. The piezoelectric actuators supplied in push-pull mode drive the support points making the mirror rotate perpendicularly to the first direction.

Abstract: The piezoactive actuator with amplified movement comprises a first sub-assembly formed by a mechanical movement amplifier and a second sub-assembly equipped with piezoactive elements. An interface with a load and an interface with a base, respectively placed at the peaks of a small axis of the shell and designed for actuating the load with respect to the base, define an actuating axis. A longitudinal deformation of the large axis enables a deformation of the small axis to be induced, designed to generate a movement at the interface with the load, the component of which movement along the small axis is amplified. At least one zone made of elastomer material is arranged at least substantially along the actuating axis to dampen deformations and increase the capacity of the actuator to resist external stresses. The actuator comprises at least one free space adjacent to the elastomer material zones in a direction orthogonal to the actuating axis.

Abstract: The motion control mechanism comprises a rotor mounted rotating around an axis. The rotor has a first threaded part and a second threaded part separated by a central part placed in contact with a stator excited by an oscillator. A frame defines a first threaded part collaborating with the first threaded part of the rotor. The second threaded part of the rotor collaborates with an output shaft. Rotation of the rotor with respect to the frame results in movement of the output shaft along the axis. The oscillator comprises an oscillating mass excited by an angular actuator formed by piezoelectric actuators arranged around a star-shaped support. The oscillator is fitted inside the rotor configured in the form of a bell and comprising several stressed sectors.

Abstract: A nanometer-scale precision actuator comprises a base, an intermediate structure, an output interface, and two linear elements producing a controllable extension in the same longitudinal direction, each between a first and a second end. A first of the two elements has a first end fixed onto the intermediate structure and a second end fixed onto the base, a second of the two elements has a first end fixed onto the intermediate structure and a second end fixed to the output interface. The base and the intermediate structure are positioned in such a manner that the controllable extension of the second element produces a displacement of the actuator in a first direction and the controllable extension of the first element produces a displacement of the actuator in a second direction, opposite to the first direction, with respect to the base.

Abstract: The actuator comprises a movable armature swivelling with respect to a stator provided with flanges on which magnets are fitted and a coil fitted around one of the flanges. The magnets have an axial magnetisation in a z axis and are aligned in an x axis. The movable armature is arranged between the magnets in the x axis. The movable armature is mounted on a guide imposing swivelling around a y axis perpendicular to the x and z axes. The movable armature is separated from the magnets by air-gaps. Each magnet forms a static magnetic circuit with one end of the movable armature and one of the flanges. The coil forms a dynamic magnetic circuit with the ends of the movable armature and the flanges.
