The present invention relates to liquid projection apparatus in the form of a face-shooter array. Material layers are used as the basis to fabricate the device to overcome constructional difficulties associated with other technologies. The device utilizes excitation of the surface layers (100) incorporating nozzles (8) which are arranged over one surface layer with addressability, forming a liquid projection array, capable of operation at high frequencies with a wide range of liquids.

1. A device for projecting liquid as jets or droplets from multiple nozzles, the device comprising: a plurality of transducers oriented substantially parallel to one another and each having an inner face and an outer face opposite said inner face, the transducers being arranged in a substantially planar array; a plurality of nozzles, each nozzle being associated with a respective transducer and having corresponding inner and outer faces and an axis normal to said inner and outer faces of said transducer, said transducer being excitable to cause movement of the associated nozzle in a direction substantially aligned with the nozzle axis, to project liquid therefrom; liquid supply means for supplying a liquid to said inner face of said nozzles; means for selectively exciting transducers as required, thereby to project liquid as jets or droplets from the respective outer face by movement of the liquid through the nozzle in response to the movement of the nozzle.
