Abstract

Système de détection capacitif comprenant un capteur capacitif (20) ayant une électrode conductrice (21) disposée pour générer un champ électrique dans une zone de détection lorsque l'électrode est soumise à un potentiel électrique, et un dispositif de commande électronique relié au moins à la première électrode. La première électrode du capteur capacitif est disposée sensiblement en totalité sur un écran conducteur (22) relié au dispositif de commande.
