Aerosolisation System and Methods of Use Thereof

Abstract

An aerosolisation system (10) is provided for producing at least one aerosol plume (78) of, optionally charged, droplets (80). The aerosolisation system (10) has a nebuliser (14a), electrically-energisable vibration means (36), and AC control circuit (46b) and an offset voltage controller (68). The nebuliser (14a) includes a vibratable sheet (34) having a first surface (38a) for receiving liquid (76) thereupon, a second surface (38b) opposite the first surface (38a), and an aperture (38c) for permitting fluid therethrough, the aperture (38c) extending from the first surface (38a) to the second surface (38b). The electrically-energisable vibration means (36) in-use causes the vibratable sheet (34) to vibrate. The AC control circuit (46b) has a programmable controller and is configured to control a power supply (30) to output an alternating current to the nebuliser (14a). The offset voltage controller (68) is configured to control a power supply (30) to output an offset voltage to the alternating current control circuit (46b) so that in-use the said alternating current outputted to the nebuliser (14a) is offset by an offset voltage for controlling the production of charged droplets (80) from a liquid (76) received on the first surface (38a).
