Abstract: A device includes: a micromechanical sensing structure configured to provide an electrical detection quantity as a function of a load; and a package enclosing the micromechanical sensing structure and providing a mechanical and electrical interface with respect to an external environment. The package includes a housing structure defining a cavity housing the micromechanical sensing structure; and a package coating that coats, at least in part, the housing structure, the package coating including a mechanical interface configured to transfer, in a uniform manner, the load on the housing structure and on the micromechanical sensing structure, wherein the housing structure includes a deformable layer interposed and in contact between the micromechanical sensing structure and the package coating, and wherein the deformable layer defines a mechanical-coupling interface.

Abstract: A sensor device for an electronic apparatus, including a sensing structure for generating a first detection signal, and a dedicated integrated circuit connected to the sensing structure for detecting a first event associated with the electronic apparatus and for generating a first interrupt signal upon detection of the first event. The dedicated integrated circuit detects the first event as a function of changes to the first detection signal over time (i.e., temporal evolution), and in particular as a function of values assumed by the first detection signal within one or more successive time windows, and of a relation between these values.

Abstract: A microelectromechanical force/pressure sensor has: a sensor die, of semiconductor material, having a front surface and a bottom surface, extending in a horizontal plane, and made of a compact bulk region having a thickness along a vertical direction, transverse to the horizontal plane; piezoresistive elements, integrated in the bulk region of the sensor die, at the front surface thereof; and a cap die, coupled above the sensor die, covering the piezoresistive elements, having a respective front surface and bottom surface, opposite to each other along the vertical direction, the bottom surface facing the front surface of the sensor die. A conversion layer is arranged between the front surface of the sensor die and the bottom surface of the cap die, patterned to define a groove traversing its entire thickness along the vertical direction; the piezoresistive elements are arranged vertically in correspondence to the groove and the conversion layer is designed to convert a load applied to the front surface of the cap die and/or bottom surface of the sensor die along the vertical direction into a planar stress distribution at the groove, acting in the horizontal plane.
