Abstract

L'invention concerne un dispositif pour détecter un objet, comprenant une bobine destinée à la production d'un champ magnétique au voisinage de la bobine, une première électrode destinée à la production d'un champ électrique au voisinage de l'électrode et un dispositif d'évaluation destiné à la détection de l'objet sur la base d'une influence exercée par le champ magnétique ou le champ électrique. A cet effet, un dispositif de séparation pour empêcher toute circulation d'un flux de courant dans la bobine permet d'utiliser la bobine comme électrode.
