Abstract
An aerosolization system comprises a gas flow passage, and an aerosol generator comprising a plate having a plurality of apertures and a vibratable element disposed to vibrate the plate. The aerosol generator is adapted to aerosolize a liquid for delivery into the gas flow passage. A flow sensor is configured to sense a gas flow through the passage, and a controller is employed to actuate the aerosol generator based on the gas flow sensed by the flow sensor.
