Abstract

La présente invention concerne un dispositif permettant d'obtenir un réseau veineux, qui comprend une partie corps (2) comprenant un composant de circuit tridimensionnel formé par obtention d'un motif conducteur (6) sur la surface d'une structure tridimensionnelle. Un trou traversant (2), correspondant à une partie insertion de doigt par laquelle un doigt est inséré, est formé dans la partie corps (2). Une source lumineuse (3), destinée à exposer un doigt inséré dans le trou traversant (2a) à un rayonnement à l'aide d'une lumière, et un élément d'imagerie (4), destiné à former une image de la lumière transmise par rapport à la lumière émise par la source lumineuse (3) et transmise à travers le doigt, sont directement montés sur une surface de paroi interne (2b) du trou traversant (2a). La précision de la position de l'installation de la source lumineuse et de l'élément d'imagerie ne cesse de s'améliorer.
