MECHANICAL STRESS DETECTION DEVICE INCLUDING A CAPACITIVE SENSOR, SET OF DETECTION DEVICES AND TOUCH LOCALIZATION DEVICE INCLUDING CAPACITIVE SENSORS

摘要

A mechanical stress detection device includes a capacitive sensor including a first electrode including a first main face, a second electrode including a second main face arranged facing the first main face of the first electrode, an elastic dielectric medium extending between the first main face of the first electrode and the second main face of the second electrode, a mechanism measuring a capacitance at terminals of the two electrodes, and a mechanism compensating mechanical stress in which a fixed part is rigidly connected to one of the first and second electrodes and a movable part relative to the fixed part including an adjustable counterweight is rigidly connected to the other of the first and second electrodes.
