    Abstract: A MEMS force sensor has: a substrate; a fixed electrode coupled to the substrate; and a mobile electrode suspended above the substrate at the fixed electrode to define a sensing capacitor, the mobile electrode being designed to undergo deformation due to application of a force to be detected. A dielectric material region is set on the fixed electrode and spaced apart by an air gap from the mobile electrode, in resting conditions. The mobile electrode comes to bear upon the dielectric material region upon application of a minimum detectable value of the force, so that a contact surface between the mobile electrode and the dielectric material region increases, in particular in a substantially linear way, as the force increases.

    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.

    CPC classification number: G01C19/5712

    Abstract: The MEMS gyroscope is formed by a substrate, a first mass and a second mass, wherein the first and the second masses are suspended over the substrate and extend, at rest, in a plane of extension defining a first direction and a second direction transverse to the first direction. The MEMS gyroscope further has a drive structure coupled to the first mass and configured, in use, to cause a movement of the first mass in the first direction, and an elastic coupling structure, which extends between the first mass and the second mass and is configured to couple the movement of the first mass in the first direction with a movement of the second mass in the second direction. The elastic coupling structure has a first portion having a first stiffness and a second portion having a second stiffness greater than the first stiffness.
