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).
