Abstract

L'invention concerne un capteur tactile, comprenant : une partie substrat isolant qui comprend une face d'agencement ; une pluralité de fils fins conducteurs qui ont été disposés à l'intérieur de la face d'agencement de la partie substrat ; et une pluralité de fils fins électriquement indépendants qui viennent en butée contre la partie de substrat et qui sont isolés de la pluralité de fils fins conducteurs. La pluralité de fils fins électriquement indépendants sont agencés à des positions proches des parties manquantes du motif formé par la pluralité de fils fins conducteurs. Avec ledit capteur tactile, des parties de séparation sont moins susceptibles d'être vues.
