Abstract: Various embodiments of the present disclosure provide a read/write device for a hard-disk memory system. The read/write device includes a fixed structure; a membrane region including a first and a second membrane, which are constrained to the fixed structure, and a central portion, interposed between the first and second membranes; a first and a second piezoelectric actuator, mechanically coupled, respectively, to the first and second membranes; and a read/write head, which is fixed to the central portion of the membrane region. The first and second piezoelectric actuators can be controlled so as to cause corresponding deformations of the first and second membranes, said deformations of the first and second membranes causing corresponding movements of the read/write head with respect to the fixed structure.

Abstract: Various embodiments provide an ejection device for a fluid. The ejection device includes a first semiconductor wafer, housing, on a first side thereof, a piezoelectric actuator and an outlet channel for the fluid alongside the piezoelectric actuator; a second semiconductor wafer having, on a first side thereof, a recess and, on a second side thereof opposite to the first side, at least one inlet channel for said fluid fluidically coupled to the recess; and a dry-film coupled to a second side, opposite to the first side, of the first wafer. The first and the second wafers are coupled together so that the piezoelectric actuator and the outlet channel are set directly facing, and completely contained in, the recess that forms a reservoir for the fluid. The dry-film has an ejection nozzle.

Abstract: A microfluidic device provided in a body accommodating a fluid containment chamber. A fluidic access channel and a drop emission channel are formed in the body and are in fluidic connection with the fluid containment chamber to form a fluidic path towards the body outside through a nozzle having an outlet section. An actuator is operatively coupled to the fluid containment chamber and is configured to cause ejection of fluid drops through the drop emission channel in an operating condition of the microfluidic device. The drop emission channel comprises a portion of reduced section having a smaller area than the outlet section of the nozzle.

Abstract: A micro-electro-mechanical (MEMS) actuator device includes a frame, and a first functional sub-structure positioned within the frame and mechanically coupled thereto by supporting elements. The first functional sub-structure is subdivided into first and second portions. The first portion is subdivided into first and second sub-portions separated from one another by a first through trench, and the second portion is subdivided into first and second sub-portions separated from one another by a second through trench. First and second piezo-electric structures are respectively carried by the first and second sub-portions of the first portion. Third and fourth piezo-electric structures are respectively carried by the first and second sub-portions of the second portion. A third through trench extends between the frame and the first functional sub-structure except for regions in which the supporting elements are present.

Abstract: An integrated device includes: a first die; a second die coupled in a stacked way on the first die along a vertical axis; a coupling region arranged between facing surfaces of the first die and of the second die, which face one another along the vertical axis and lie in a horizontal plane orthogonal to the vertical axis, for mechanical coupling of the first and second dies; electrical-contact elements carried by the facing surfaces of the first and second dies, aligned in pairs along the vertical axis; and conductive regions arranged between the pairs of electrical-contact elements carried by the facing surfaces of the first and second dies, for their electrical coupling. Supporting elements are arranged at the facing surface of at least one of the first and second dies and elastically support respective electrical-contact elements.

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.

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 pressure sensor with double measuring scale includes: a flexible body designed to undergo deflection as a function of a the pressure; piezoresistive transducers for detecting the deflection; a first focusing region designed to concentrate, during a first operating condition, a first value of the pressure in a first portion of the flexible body so as to generate a deflection of the first portion of the flexible body; and a second focusing region designed to concentrate, during a second operating condition, a second value of said pressure in a second portion of the flexible body so as to generate a deflection of the second portion of the flexible body. The piezoresistive transducers correlate the deflection of the first portion of the flexible body to the first pressure value and the deflection of the second portion of the flexible body to the second pressure value.
