Abstract
Disclosed herein is a piezoelectric liquid delivery system or atomizer for production of droplets of liquid or liquid suspensions by means of a battery operated atomizer utilizing an orifice plate in communication with a ceramic piezoelectric element. By use of solder joining to bond the orifice plate to the piezoelectric element, and subsequent repolarization of the piezoelectric element if necessary, superior results are achieved.
