Abstract
An electronically actuated droplet delivery device includes a housing with an airflow exit at a mouthpiece and an airflow entrance in fluid communication with the airflow exit via an airflow channel. An aperture plate coupled to an electronic actuator energized by a power source produces a droplet plume from a fluid reservoir in fluid communication with the aperture plate. A change of airflow trajectory in the airflow channel and/or a fan provides inertial filtering and removal of droplets in the plume that have a mass mean aerodynamic diameter greater than 5 μm.
