Abstract
Ce dispositif comporte un capteur capacitif 1 associé à un circuit de contrôle. Les variations de capacité du capteur en fonction des variations des déformations auquel est soumis ce capteur ne dépendent essentiellement que de l'aire des zones de déformation. Le dispositif permet de déterminer si le nombre de personnes ou d'objets présents à la surface du capteur dépasse un nombre donné
