<p>A liquid storage and transfer device for the storage and transferof liquids at irregular intervals, the device including a reservoir structure (114) defining a plurality of independent reservoir channels (116), a nozzle structure (112) secured to the reservoir structure and defining a plurality of outlet nozzles (110), and an actuator structure sandwiched between the reservoir structure and the nozzle structurefor actuating the release of liquid from the outlet nozzles, the outlet nozzles being replenished after each release with liquid from the reservoir channels via a plurality of through holes defined by the actuator structure; wherein the actuator structure comprises an array of piezolectric cantilevers (102) defined by an array of slots (100) formed in a continuous piezoelectric structure, each cantilever associated with a respective outlet nozzle (110) and supported fordeflection upon stimulation of a piezoelectric effect, such deflection stimulating the release of a controlled amount of liquid from the respective outlet nozzle.</p> |
