1. An atomizer assembly for an aerosol-generating device, the atomizer assembly comprising:
a mesh, comprising:
a first surface, a second surface, and a plurality of nozzles extending between the first surface and the second surface,
wherein the second surface is at least partially coated with a hydrophobic coating,
wherein the plurality of nozzles defines an inner surface,
wherein the inner surface is at least partially coated with the hydrophilic coating,
wherein each nozzle comprises a first opening in the first surface and a second opening in the second surface, wherein the first opening is wider than the second opening and the second opening has a diameter of 2.5 μm to 4 μm, and
an elastically deformable element;
a cavity disposed between the mesh and the elastically deformable element;
a liquid inlet configured to provide a supply of liquid to be atomized to the cavity; and
an actuator configured to oscillate the elastically deformable element,
wherein the mesh is disposed such that the first surface of the mesh faces the cavity and the second surface of the mesh faces an outside of the atomizer assembly.
