An atomiser assembly is provided, including: an oscillation chamber having a cavity containing a liquid to be atomized, a liquid inlet configured to provide a supply of the liquid to be atomized to the cavity, an elastically deformable element, and a mesh element comprising a plurality of nozzles; and an actuator configured to oscillate the elastically deformable element, the oscillation chamber and the liquid being contained in the cavity of the oscillation chamber form an oscillation system, in which oscillation of the elastically deformable element by the actuator varies pressure inside the cavity, and the actuator being further configured to oscillate the elastically deformable element at a resonant frequency of the oscillation system to eject liquid contained in the cavity from the cavity through the plurality of nozzles of the mesh element. An aerosol-generating system, an aerosol-generating device, and a method of operating an atomiser assembly are also provided.

A mesh element for an atomiser assembly is provided, including: a first layer defining at least one channel including a minimum cross-sectional area; and a second layer overlying the first layer and defining at least one nozzle including a maximum cross-sectional area, the second layer including an inner surface facing the first layer and an outer surface facing away from the first layer, the at least one nozzle overlying the at least one channel, and the maximum cross-sectional area of the at least one nozzle being smaller than the minimum cross-sectional area of the at least one channel, and the outer surface of the second layer defining an annular portion extending around the at least one nozzle, the annular portion having a semi-circular cross-sectional shape, and a thickness of the second layer at each annular portion being larger than a thickness of the second layer between adjacent annular portions.
