Abstract

La présente invention concerne un dispositif tactile (10). Le dispositif tactile (10) comprend une pluralité de premières électrodes tactiles (112) et une pluralité de secondes électrodes tactiles (132). La pluralité de premières électrodes tactiles (112) et la pluralité de secondes électrodes tactiles (132) sont entrelacées pour définir une pluralité de premières régions entrelacées (R1). Chacune des premières électrodes tactiles (112) comprend une pluralité de premières jonctions (112a) s'étendant dans une première direction (d1) et une pluralité de secondes jonctions (112b) s'étendant dans une seconde direction (d2). La pluralité de premières jonctions (112a) et la pluralité de secondes jonctions (112b) se croisent pour former une pluralité de premières grilles (112h). Chacune des premières électrodes tactiles (112) comprend en outre une pluralité de premières branches (112c). Les premières branches (112c) se croisent en deux segments (112as, 112bs) de deux premières jonctions adjacentes (112a) d'au moins une première grille (112h).
