    Abstract: A pressure sensor device is to be positioned within a material where a mechanical parameter is measured. The pressure sensor device may include an IC having a ring oscillator with an inverter stage having first doped and second doped piezoresistor couples. Each piezoresistor couple may include two piezoresistors arranged orthogonal to one another with a same resistance value. Each piezoresistor couple may have first and second resistance values responsive to pressure. The IC may include an output interface coupled to the ring oscillator and configured to generate a pressure output signal based upon the first and second resistance values and indicative of pressure normal to the IC.

    Abstract: A MEMS resonant accelerometer is disclosed, having: a proof mass coupled to a first anchoring region via a first elastic element so as to be free to move along a sensing axis in response to an external acceleration; and a first resonant element mechanically coupled to the proof mass through the first elastic element so as to be subject to a first axial stress when the proof mass moves along the sensing axis and thus to a first variation of a resonant frequency. The MEMS resonant accelerometer is further provided with a second resonant element mechanically coupled to the proof mass through a second elastic element so as to be subject to a second axial stress when the proof mass moves along the sensing axis, substantially opposite to the first axial stress, and thus to a second variation of a resonant frequency, opposite to the first variation.
