Abstract: A MEMS actuator device of a piezoelectric type formed on a substrate, with a base unit including a base beam element having a main extension in a extension plane and a thickness in a thickness direction perpendicular to the extension plane, smaller than the main extension. A piezoelectric region extends over the beam element. An anchor region is rigid to the base beam element and to the substrate. A base constraint structure is connected to one end of the base beam element and is configured to allow a deformation of the base beam element in the extension plane and substantially reduce a deformation of the base beam element in the thickness direction.

Abstract: A load-sensing device is arranged in a package forming a chamber. The package has a deformable substrate configured, in use, to be deformed by an external force. A sensor unit is positioned in direct contact with the deformable substrate and is configured to detect deformations of the deformable substrate. An elastic element within of the chamber is arranged to act between the package and the sensor unit to generate, on the sensor unit, a force keeping the sensor unit in contact with the deformable substrate. The deformable substrate may be a base of the package, and the elastic element may be a metal lamina arranged between the lid of the package and the sensor unit. The sensor unit may be a semiconductor die integrating piezoresistors.

Abstract: A MEMS device includes a fixed structure and a mobile structure with a reflecting element coupled to the fixed structure through at least a first deformable structure and a second deformable structure. Each of the first and second deformable structures includes a respective number of main piezoelectric elements, with the main piezoelectric elements of the first and second deformable structures configured to be electrically controlled for causing oscillations of the mobile structure about a first axis and a second axis, respectively. The first deformable structure further includes a respective number of secondary piezoelectric elements configured to be controlled so as to vary a first resonance frequency of the mobile structure about the first axis.

Abstract: A fluid ejection device, comprising: a first semiconductor body including an actuator, which is operatively coupled to a chamber for containing the fluid and is configured to cause ejection of the fluid; and a channel for inlet of the fluid, which extends in a first direction and has a section having a first dimension; and a second semiconductor body, which is coupled to the first semiconductor body and has an ejection nozzle configured to expel the fluid. The second semiconductor body further comprises a first restriction channel, which is fluidically coupled to the inlet channel, extends in a second direction orthogonal to the first direction and has a respective section with a second dimension smaller than the first dimension so as to form a restriction between the inlet channel and the chamber.

Abstract: The present disclosure is directed to a microfluidic die that includes a first larger heater and a second smaller heater is a single chamber. The first heater is configured to form a primary bubble that ejects fluid from a nozzle associated with the chamber. The second heater is configured to form a secondary bubble to prevent blow back caused when the primary bubble bursts and ejects fluid from the nozzle. The first and second heater may be coupled to a single input trace and a single ground trace.
