    • MEMS and/or NEMS pressure sensor including, in a substrate: a stationary portion and a portion that is movable relative to the stationary portion, the movable portion comprising a sensitive element (108) that is able to move in the plane of the sensor under the effect of a pressure variation; a stress gauge (18) for detecting the movement of the sensitive element (108) in the plane of the sensor due to the pressure variation; electrodes (24.1, 24.2) for actuating the sensitive element, said actuating electrodes being borne partially by the stationary portion and partially by the movable portion, said actuating electrodes being commanded so as to automatically control positionwise the movement of the sensitive element (108); and means (C) for commanding the actuating electrodes, which are configured, on the basis of signals emitted by the gauge, to bias the actuating electrodes so as to automatically control positionwise the movement of the sensitive element.
    • MEMS和/或NEMS压力传感器,其包括:在基板中:固定部分和可相对于固定部分移动的部分,所述可移动部分包括敏感元件(108),所述敏感元件能够在所述传感器的平面内移动 压力变化的影响; (18),用于检测由于压力变化而引起的敏感元件(108)在传感器平面中的移动; 用于致动所述敏感元件的电极(24.1,24.2),所述致动电极由所述静止部分部分地承载并且部分地由所述可动部分承载,所述致动电极被命令以自动地控制所述敏感元件(108)的运动的位置; 和用于命令所述致动电极的装置(C),所述致动电极基于由所述量表发出的信号而被配置为偏压所述致动电极以便自动地控制所述敏感元件的运动的位置。
