Abstract: An integrated electronic system is provided with a package formed by a support base and a coating region arranged on the support base and having at least a first system die, including semiconductor material, coupled to the support base and arranged in the coating region. The integrated electronic system also has, within the package, a monitoring system configured to determine the onset of defects within the coating region, through the emission of acoustic detection waves and the acquisition of corresponding received acoustic waves, whose characteristics are affected by, and therefore are indicative of, the aforementioned defects.

Abstract: A substrate has a plurality of microdots positioned thereon. Each microdot contains one or more primers for gene amplification for a particular target gene. The microdots are placed on the substrate and the substrate is positioned in a housing. The housing has a sample fluid to be tested introduced therein covering the microdot array. While the sample fluid is overlying the substrate, the amplification of the target gene is carried out if it is present within the sample. If the target gene that matches the primers is not present, then amplification will not take place. The fluid also contains fluorophores which will be fixed into the gene as it increases in size as it clearly detects if gene amplification has occurred by detecting the amount of light detected for a particular microdot. In a preferred embodiment, the sample fluid is placed on top of a sealing layer that is less dense then water, such as wax or mineral oil. During a heating of the sample fluid and sealing layer, the sample fluid will sink to the bottom of the sealing layer so that it is fully encased and protected.

Abstract: PMUT acoustic transducer formed in a body of semiconductor material having a face and accommodating a plurality of first buried cavities, having an annular shape, arranged concentrically with each other and extending at a distance from the face of the body. The first buried cavities delimit from below a plurality of first membranes formed by the body so that each first membrane extends between a respective first buried cavity of the plurality of first buried cavities and the face of the body. A plurality of piezoelectric elements extend on the face of the body, each piezoelectric element extending above a respective first membrane of the plurality of first membranes. The first membranes have different widths, variable between a minimum value and a maximum value.

Abstract: A microfluidic device for continuous ejection of fluids includes: a semiconductor body that laterally delimits chambers; an intermediate structure which forms membranes each delimiting a top of a corresponding chamber; and a nozzle body which overlies the intermediate structure. The device includes, for each chamber: a corresponding piezoelectric actuator; a supply channel which traverses the intermediate structure and communicates with the chamber; and a nozzle which traverses the nozzle body and communicates with the supply channel. Each actuator is configured to operate i) in a resting condition such that the pressure of a fluid within the corresponding chamber causes the fluid to pass through the supply channel and become ejected from the nozzle as a continuous stream, and ii) in an active condition, where it causes a deformation of the corresponding membrane and a consequent variation of the pressure of the fluid, causing a temporary interruption of the continuous stream.

Abstract: A PMUT device includes a membrane element extending perpendicularly to a first direction and configured to generate and receive ultrasonic waves by oscillating about an equilibrium position. At least two piezoelectric elements are included, with each one located over the membrane element along the first direction and configured to cause the membrane element to oscillate when electric signals are applied to the piezoelectric element, and generate electric signals in response to oscillations of the membrane element. The membrane element has a lobed shape along a plane perpendicular to the first direction, with the lobed shape including at least two lobes. The membrane element includes for each piezoelectric member a corresponding membrane portion including a corresponding lobe, with each piezoelectric member being located over its corresponding membrane portion.

Abstract: A MEMS actuator includes a main body having a central portion, couplable to a substrate, and a peripheral portion suspended over the substrate when the central portion is coupled to the substrate. The peripheral portion has a deformable structure extending around the central portion, and forming successively arranged membranes. The MEMS actuator includes bearing structures and corresponding piezoelectric actuators. The bearing structures are fixed at their top to the deformable structure and laterally delimit corresponding cavities, each having a lateral opening facing the central portion of the main body and closed at the top by a membrane. A fixed part of the membrane is fixed to the underlying bearing structure and a suspended part is laterally offset with respect to the underlying bearing structure. The piezoelectric actuators are controllable to cause deformation of the corresponding membrane and rotation of the bearing structures around the central portion of the main body.

Abstract: A MEMS actuator includes a monolithic body of semiconductor material, with a supporting portion of semiconductor material, orientable with respect to a first and second rotation axes, transverse to each other. A first frame of semiconductor material is coupled to the supporting portion through first deformable elements configured to control a rotation of the supporting portion about the first rotation axis. A second frame of semiconductor material is coupled to the first frame by second deformable elements, which are coupled between the first and the second frames and configured to control a rotation of the supporting portion about the second rotation axis. The first and second deformable elements carry respective piezoelectric actuation 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.
