Abstract

L'invention concerne une structure de détection capacitive à plusieurs canaux qui comprend un élément sur un premier côté ayant une première surface pourvue de deux zones, ou plus, électriquement conductrices, séparées l'une de l'autre par une limite non-conductrice, et de deux conducteurs isolés, ou plus, agencés sur une seconde surface non conductrice électriquement, sur un second côté de l'élément opposé au premier côté, espacés de chaque zone conductrice par l'élément et couplés de manière capacitive à celle-ci.
