Abstract

An apparatus for atomising liquid, including a piezoelectric substrate (1) having a working surface (3), and a peripheral edge (7) extending along a side of the working surface, an interdigital transducer (2) located on the working surface for generating surface acoustic waves (SAW) in the working surface, and a liquid delivery arrangement including a porous member (8) for supplying the liquid to be atomised, wherein the porous member is in contact with the peripheral edge of the piezoelectric substrate.
