Abstract

La présente invention concerne un produit tricoté (21) et un procédé pour sa fabrication. Le produit tricoté (21) est fabriqué d'une seule pièce sur une machine à tricoter (10) en tricotant plusieurs couches de tricot (19). Dans un segment fonctionnel se trouvent au moins une première couche de tricot (19a) et une seconde couche de tricot (19b). Facultativement, il est possible de prévoir une couche de tricot (19c) centrale intercalée entre les deux. Dans les couches du segment fonctionnel (29) sont formées deux zones d'électrodes (30, 31) séparées électriquement l'une de l'autre ainsi qu'une zone de couplage (32) couplant électriquement les deux zones d'électrodes (30, 31). Les zones d'électrodes (30, 31) sont fabriquées en utilisant un fil électroconducteur (38) lors du tricotage de chaque zone. La zone de couplage est ainsi conçue pour modifier un couplage électrique entre les deux zones d'électrodes (30, 31) en fonction d'une action extérieure.
