The device has a force or pressure sensor (1) with a body (8) having a recess (9) arranged in a manner that a reaction disk (7) is deformed and thrusted in the recess, when force is applied in the disk, where the disk is made of elastomer material. A displacement sensor (11) measures a displacement (C), which depends on the thrusting of the disk in the recess, where the sensor measures displacement of a curser (10). The curser is arranged in the recess in a manner to be displaced under the effect of the thrusting. Capteur de force ou de pression (1) caractérisé par le fait qu'il comprend un disque de réaction (7), un corps (8) présentant un évidement (9) agencé de manière que quand une force est appliquée sur le disque de réaction, le disque de réaction se déforme et s'enfonce dans l'évidement, et un capteur de déplacement (11) apte à mesurer un déplacement (C) qui dépend de l'enfoncement du disque de réaction dans l'évidement.
