    Abstract: A microfluidic dispenser device of inhalable substances includes a casing, housed in which are a driving circuit and a microfluidic cartridge having a tank that contains a liquid to be delivered. The microfluidic cartridge is provided with at least one nebulizer controlled by the driving device. The nebulizer includes: a substrate; a plurality of chambers formed on the substrate and fluidically coupled to the tank for receiving the liquid to be delivered; and a plurality of heaters, which are formed on the substrate in positions corresponding to respective chambers, are thermally coupled to the respective chambers and are separated from the respective chambers by an insulating layer, and are controlled by the driving device. Each chamber is fluidically connected with the outside by at least one respective nozzle.

    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: Ejection device for fluid, comprising a solid body including: first semiconductor body including a chamber for containing the fluid, an ejection nozzle in fluid connection with the chamber, and an actuator operatively connected to the chamber to generate, in use, one or more pressure waves in the fluid such as to cause ejection of the fluid from the ejection nozzle; and a second semiconductor body including a channel for feeding the fluid to the chamber, coupled to the first semiconductor body, in such a way that the channel is in fluid connection with the chamber. The second semiconductor body integrates a damping cavity over which extends a damping membrane, the damping cavity and the damping membrane extending laterally to the channel for feeding the fluid.

    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.
