USPTO Abstract

A surface acoustic wave (SAW) atomizer system for use in providing a nebulized medicament to a patient is described. The system may include a SAW atomization engine with an atomization region on a substrate that is separated from the interdigitated transducers (IDTs) on the substrate by a fluid barrier that seals off liquid fed into the atomization region from the adjacent IDTs and electrical contacts driving the IDTs.
