A microelectromechanical sensor device has a detection structure, having: a substrate, with a top surface; an inertial mass, suspended above the top surface of the substrate and elastically coupled to a rotor anchor so as to perform an inertial movement relative to the substrate as a function of a quantity to be detected; and stator electrodes, integrally coupled to the substrate at respective stator anchors and capacitively coupled to the inertial mass so as to generate a differential capacitive variation in response to, and indicative of, the quantity to be detected. In particular, the inertial mass performs, as the inertial movement, a translation movement along a vertical axis orthogonal to the top surface of the substrate; and the stator electrodes are arranged in a suspended manner above the top surface of the substrate.

The present disclosure is directed to micro-electromechanical system (MEMS) accelerometers that are configured for a user interface mode and a true wireless stereo (TWS) mode of an audio device. The accelerometers are fabricated with specific electromechanical parameters, such as mass, stiffness, active capacitance, and bonding pressure. As a result of the specific electromechanical parameters, the accelerometers have a resonance frequency, quality factor, sensitivity, and Brownian noise density that are suitable for both the user interface mode and the TWS mode.

Dual-operating accelerometer

Embodiment of a system for generating electric power with micro fuel cells comprising at least one first micro cell and at least one second micro cell, each micro cell having an anode and a cathode with a membrane being sandwich-wise interposed, the system comprising a spacer element having an annular element that surrounds a cavity, said spacer element being associated with said anode of said first micro cell and with said anode of said second micro cell to realize a common diffusion chamber for the fuel of said first micro cell a of said second micro cell.

System for generating electric power with micro fuel cells and corresponding process

A microfluidic device (-), comprising: a semiconductor body () having a first side () and a second side () opposite to one another, and housing, at the first side, a plurality of wells (), having a first depth; an inlet region () forming an entrance point for a fluid to be supplied to the wells; a main channel () fluidically connected to the inlet region, and having a second depth; and a plurality of secondary channels () fluidically connecting the main channel to a respective well, and having a third depth. The first depth is higher than the second depth, which in turn is higher than the third depth. According to an aspect, the microfluidic device further comprises a cover layer (), arranged above the first side of the semiconductor body, configured for sealing the wells and provided with at least a first valve hole () which extends through the cover layer and overlaps, at least partially, the secondary channels; and a flexible layer (), arranged above the cover layer and provided with at least a protrusion () extending through the first valve hole towards the semiconductor body and overlapping, at least partially, the secondary channels, the flexible layer being configured such that, when a pressure is applied on it, the protrusion contacts the semiconductor body and enters the secondary channels thus fluidically isolating the wells from one another.

Microfluidic PCR device

A device for producing energy for portable applications including at least one micro fuel cell and a microreactor, having a reaction chamber including a catalyst, for producing hydrogen gas to be fed to the micro fuel cell.
