A device for applying a plurality of microdroplets onto a substrate comprises a dosing head substrate (10) having a plurality of nozzle openings (16) formed therein. For each nozzle opening (16), there is provided a media portion (18) to be filled with a liquid to be dosed. There is provided a deformable component (28) that is arranged adjacent the media portions (18). Finally, the device comprises an actuating means (34) for actuating the deformable component (30) such that the deformable component (30) deforms into the media portions (18) so as to simultaneously expel microdroplets from the plurality of nozzle openings (16).
L'invention concerne un dispositif pour déposer une pluralité de microgouttelettes sur un substrat. Ce dispositif comprend un substrat (10) à tête de dosage, dans lequel une pluralité d'ouvertures (16) d'ajutages est formée. Une zone (18) destinée à contenir un liquide à doser est prévue au niveau de chaque ouverture (16) d'ajutage. Un élément de construction déformable (28) également prévu avoisine les zones (18) servant à contenir le liquide concerné. Ce dispositif comporte enfin un dispositif d'actionnement (34) conçu pour actionner l'élément de construction déformable (30), de sorte que cet élément de construction déformable (30) se déforme dans lesdites zones (18) pour éjecter simultanément des microgouttelettes hors de la pluralité d'ouvertures (16) d'ajutages.
