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).The invention relates to a device for forming waves at the interface (I) of a drop of liquid (F1) by electrowetting, allowing the micro-mixing and the concentration of constituents at the interface (I) of the droplet. (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).

Figure imgaf001
The device comprises at least one excitation electrode (20; 30) adapted to generate an oscillating and radial electric field around a first axis of symmetry, under the effect of electrical control, and a drop of liquid (F1 ) disposed on said excitation electrode (20; 30) and having an axis of symmetry substantially coinciding with said first axis of symmetry, such that said electric field generates substantially axisymmetric waves at the interface (I) of said droplet ( F1).
