Abstract
An accelerometer sensor having electrodes forming capacitors of capacitance that vary as a function of distances between the electrodes, a control unit being arranged to perform an operation of measuring the capacitances and a control operation that comprises selectively: a fine control stage in which a first voltage is applied between one of the stationary electrodes and the movable electrode, while the other stationary electrode is at the same potential as the movable electrode; and an extended control stage in which a second voltage is applied between one of the stationary electrodes and the movable electrode, the other stationary electrode being at the same potential as the movable electrode, and the second voltage being greater in absolute value than the first voltage. A method using such a sensor.
