<p>The invention provides an aerosol delivery method and system for producing a charged electrohydrodynamic (EHD) aerosol, discharging the aerosol and moving the discharged aerosol in a desired direction without substantial wetting of the device. The delivery system may include a spray nozzle (20) for dispensing the fluid to be aerosolized and negatively charging the aerosol droplets, a discharge electrode (70) generally downstream of the spray nozzle for generating a positive ion stream which intercepts and electrically neutralizes the negative aerosol droplets while also imparting a desired movement on the aerosol in a direction generally away from the discharge electrode and a reference electrode (40) between the spray nozzle and the discharge electrode for modifying the electric field between the spray nozzle and the discharge electrode.</p> |
