Abstract
Official abstract text for this publication.
A droplet dispensing device includes a reservoir for receiving a liquid material, an outlet nozzle in fluid communication with the reservoir and a piezoelectric actuating means acting on the liquid material at the outlet nozzle to exit the outlet nozzle in a sequence of droplets. A piezoelectric actuating means that includes a piston, which is actuated by a piezoelectric actuator at one end and dips the other, free end into the liquid material is provided just upstream of the outlet nozzle.
First claim
