Abstract

Disclosed herein is a piezoelectric liquid delivery system or atomizer for production of droplets of liquid suspensions by means of a battery operated dispenser utilizing an orifice plate (3) in communication with a piezoelectric element (2). By control of the viscosity and surface tension of the liquid to be dispersed, an improved method of dispensing such liquid is achieved.
