Abstract
A microstructured passage module for aerosolizer is disclosed. The module includes a plate overlaid by a cover, an entrance, an exit, a plurality of protrusions and a plurality of pillars. The protrusions and pillars project from and are integral parts of the plate. Further, the plate can be divided into a first zone proximate to the entrance and a second zone proximate to the exit. The protrusions are arranged into parallel rows in a direction from the entrance to the exit and form parallel passages therebetween in the first zone for the liquid to flow along. The protrusions in each column are spaced from one another by tunnels. The pillars are interposingly disposed in the second zone and define certain channels therebetween. Moreover, a plurality of pillars further disposed in the passages increase a flow resistance for the liquid flowing through the passages.
