Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for the atomisation of a liquid including: a piezoelectric substrate having at least one working surface and at least one electrode supported on the piezoelectric substrate, the electrode being an elliptical electrode width controlled single phase unidirectional transducer (EWC SPUDT); signal generating means for applying an ultrasonic signal to said electrode for generating a surface acoustic wave (SAW) in the working surface of the pie…
