Abstract

See full text

A method for aerosolizing a liquid comprises providing an aerosol generator having a plate with a plurality of apertures and a piezoelectric element to vibrate the plate. Liquid is supplied to the plate, and the piezoelectric element is energized to vibrate the plate at an initial frequency. The energy level is adjusted to vibrate the plate at its instantaneous resonant frequency during aerosolization of the liquid.
