Abstract
The invention is an apparatus and methods for optimizing the performance and protecting one or more aerosol generating transducers from deterioration while operating in a chemically reactive aqueous solution by utilizing one or more protective barrier techniques to eliminate chemical interaction between the aqueous solution and the transducers. The method of the present invention produces an aerosol producing transducer with the transducer housing and assembly to be constructed in such a way as to assure its efficient and effective long-term and problem free operation in an aqueous solution that is chemically reactive.
