Abstract
An aerosol-generator for an aerosol-generating device is provided, the aerosol-generator including: a surface acoustic wave atomiser including a substrate including an active surface defining an atomisation region, and a transducer positioned on the active surface of the substrate configured to generate surface acoustic waves on the active surface of the substrate; a portion of the active surface of the substrate underlying at least a portion of the transducer including a surface treatment; and a supply element arranged to supply a liquid aerosol-forming substrate to the atomisation region.
