Abstract

L'invention concerne un dispositif (100) et un procédé de mesure d'une propriété d'éléments fonctionnels électroniques, en particulier, d'éléments fonctionnels électroniques obtenus par des procédés d'impression, lesdits éléments fonctionnels électroniques étant constitués par des zones partielles d'une bande souple (2). Le dispositif (100) est caractérisé en ce qu'il présente une roue de mesure (1) qui tourne à une vitesse de rotation (11), ainsi qu'un système de guidage de bande (30a, 30b, 31a, 31b) destiné à guider en continu la bande (2), à une vitesse périphérique (21), autour de la roue de mesure (1), et en ce que la vitesse périphérique (21) est ajustée par rapport à la vitesse de rotation (11) de la roue de mesure (1), de telle façon que pendant la rotation, la bande (2) s'applique sur une périphérie de la roue de mesure (1) et que les éléments fonctionnels de la bande (2) entraînée en rotation prennent un emplacement constant par rapport à la périphérie. Le dispositif (100) présente également un système de mesure (13) intégré dans la roue de mesure, lequel effectue la mesure sur les éléments fonctionnels de la bande (2), pendant que la bande (2) tourne autour de ladite roue de mesure (1).
