Abstract

L'invention concerne un dispositif de formation d'ondes à l'interface (I) d'une goutte de liquide (F1) par électromouillage, permettant le micro-mélange et la concentration de constituants à l'interface (I) de la goutte (F1).
Le dispositif comprend au moins une électrode d'excitation (20; 30) adaptée à générer un champ électrique oscillant et radial autour d'un premier axe de symétrie, sous l'effet d'une commande électrique, et une goutte de liquide (F1) disposée sur ladite électrode d'excitation (20 ; 30) et présentant un axe de symétrie coïncidant sensiblement avec ledit premier axe de symétrie, de sorte que ledit champ électrique génère des ondes essentiellement axisymétriques à l'interface (I) de ladite goutte (F1).
