Abstract

A droplet deposition apparatus including a channel (10) having deformable side walls (14) actuated by a piezoelectric element (18) forming the roof of the channel. The roof is caused to expand or contract in a direction perpendicular to the plane of the walls, and causes the walls to deform into the channel. The walls can act to amplify small deflections of the actuator to cause sufficiently large changes of volume in the channel. The piezoelectric is typically high activity piezoelectric and preferably single crystal ceramic.
