Abstract
An apparatus (1) for the atomisation of a liquid including: a piezoelectric substrate (5) having at least one working surface (7), at least one electrode (9) supported on the piezoelectric substrate (5), a signal generating means (21) for applying an ultrasonic signal to said electrode (9) for generating a surface acoustic wave (SAW) in the working surface (7) of the piezoelectric substrate (5); a liquid delivery arrangement (11) including a wick (17) in contact with the working surface (7) for delivering liquid thereof, wherein liquid delivered to the working surface (7) is atomised by SAW irradiation.
