1. A vaping device for aerosol-generation, comprising:
a device housing including a storage portion, the storage portion including a storage housing configured to hold an aerosol-forming substrate;
a surface acoustic wave-atomizer (SAW-atomizer) including an atomization region and a first transducer, the first transducer configured to generate first surface acoustic waves that propagate along a surface of the SAW-atomizer including the atomization region, the atomization region and the first transducer are mounted on a surface of a piezoelectric substrate;
a supply element configured to supply the aerosol-forming substrate from the storage portion to the atomization region, the supply element including a capillary element extending onto the surface of the piezoelectric substrate;
a resistive heater arranged on a same surface of the SAW-atomizer as the atomization region and the first transducer, the resistive heater at an edge of the piezoelectric substrate opposite the first transducer, the supply element at least partially overlying the resistive heater and configured to transport the aerosol-forming substrate from the storage portion to the atomization region; and
a control system configured to operate the SAW-atomizer to atomize the aerosol-forming substrate in the atomization region to generate an aerosol.
