  • Patent number: 10310253
    Abstract: A MEMS device includes a fixed structure and suspended structure including an internal structure and a first arm and a second arm. Each arm has a first end fixed to the fixed structure and a second end fixed to the internal structure. The ends are angularly arranged at a distance apart. Piezoelectric actuators mounted to the arms are driven so as to cause deformation of the arm and produce a rotation of the internal structure. In a resting condition, each of the first and second arms has a respective elongated portion with a respective concavity. The internal structure extends in part within the concavities of the elongated portions of the first and second arms.

  • Publication number: 20190161338
    Abstract: A micro-electro-mechanical actuator device includes a fixed structure and a mobile structure. The mobile structure includes a first deformable band, a second deformable band, and a third deformable band, both of which extend on opposite sides of the first deformable band, each of which carries a piezoelectric actuator. In a working condition, in which the second and third piezoelectrics are biased, the second and third deformable bands are subjected to a negative bending, while the first deformable band is subjected to a positive bending. There are thus generated two translations that add together, causing a displacement of the first deformable band greater than the one that may be obtained by a single membrane of an equal base area.

  • Publication number: 20190068934
    Abstract: Disclosed herein is a MEMS device including a fixed structure, a mobile structure, and deformable structures extending therebetween. The deformable structures have first ends anchored along X and Y axes of the fixed structure, and have second ends anchored offset from the X and Y axes of the fixed structure. The deformable structures are shaped so as to curve from their anchoring points along the mobile structure back toward the mobile structure, to extend along the perimeter of the mobile structure, and to then curve away from the mobile structure and toward their anchoring points along the fixed structure. Each deformable structure has two piezoelectric elements that extend along the length of that deformable structure, with one piezoelectric element having a greater length than the other piezoelectric element.

  • Publication number: 20190023014
    Abstract: The microfluidic device has a plurality of ejector elements. Each ejector element includes a first region, accommodating a first fluid flow channel and an actuator chamber; a second region, accommodating a fluid containment chamber; and a third region, accommodating a second fluid flow channel. The fluid containment chamber is fluidically coupled to the first and to the second fluid flow channels. The second region is formed from a membrane layer, from a membrane definition layer, mechanically coupled to the membrane layer and having a membrane definition opening, and a fluid chamber defining body, mechanically coupled to the membrane definition layer and having a chamber defining opening, with a width greater than the width of the membrane definition opening. The width of the membrane is thus defined by the width of the chamber defining opening.

  • Patent number: 10175474
    Abstract: A micromechanical device includes a tiltable structure that is rotatable about a first rotation axis. The tiltable structure is coupled to a fixed structure through an actuation structure of a piezoelectric type. The actuation structure is formed by spring elements having a spiral shape. The spring elements each include actuation arms extending transversely to the first rotation axis. Each actuation arm carries a respective piezoelectric band of piezoelectric material. The actuation arms are divided into two sets with the piezoelectric bands thereof biased in phase opposition to obtain rotation in opposite directions of the tiltable structure about the first rotation axis.

  • Patent number: 10024738
    Abstract: A MEMS force sensor has: a substrate; a fixed electrode coupled to the substrate; and a mobile electrode suspended above the substrate at the fixed electrode to define a sensing capacitor, the mobile electrode being designed to undergo deformation due to application of a force to be detected. A dielectric material region is set on the fixed electrode and spaced apart by an air gap from the mobile electrode, in resting conditions. The mobile electrode comes to bear upon the dielectric material region upon application of a minimum detectable value of the force, so that a contact surface between the mobile electrode and the dielectric material region increases, in particular in a substantially linear way, as the force increases.
