Abstract

La présente invention concerne une micropompe comprenant un microcanal (10) formé dans un substrat (15). Le microcanal comprend une pluralité de couches annulaires d'électrodes (25, 30) à l'intérieur du microcanal. Des couches d'électrodes alternantes sont recouvertes d'un fluoropolymère ou d'une autre substance hydrophobe (20) qui devient hydrophile en réponse à l'application d'un signal de tension. Les électrodes recouvertes d'un matériau fluoropolymère (25) définissent des zones hydrophobes intercalées entre des zones hydrophiles définies par des couches annulaires d'électrodes (30) exposées. Lorsqu'un fluide se propageant à l'intérieur du microcanal approche d'une zone hydrophobe, les propriétés hydrophobes de la surface du microcanal de cette zone empêchent un ménisque formé par le fluide de se propager. L'application d'une tension sur la zone hydrophobe la rend hydrophile, ce qui permet au ménisque, et à la colonne de fluide qui le suit, de se propager dans cette zone sous l'effet des forces capillaires. Lorsqu'il rencontre la zone hydrophobe suivante, le ménisque est à nouveau bloqué. Une application sélective de signaux de tension sur les électrodes dans des zones hydrophobes consécutives permet de commander la vitesse d'écoulement de colonnes de fluide, telle que déterminée par les dimensions du microcanal (telles que le diamètre d'un microcanal présentant une section transversale circulaire) et les propriétés du fluide se propageant (telles que la viscosité).
