A device for generating droplets of fluid has a fluid supply reservoir and an electromechanical transducer. Electrodes are arranged to cause expansion and contraction of the transducer in a dimension perpendicular to the applied electric field. A perforated element is coupled for movement with the expansion and contraction of the transducer and is positioned for contact with the fluid supply for dispensing droplets therethrough.

[ We claim:] [1.] A device for generating droplets of fluid, the device comprising:a fluid supply means;an electromechanical transducer having electrodes arranged so as to operate in extensional mode to cause expansion or contraction of the transducer in a dimension perpendicular to the applied electric field; andan element coupled for movement with the expansion/contraction of the transducer in the direction of said dimension and positioned for contact with fluid from the supply means, said fluid supply means being adapted to supply fluid to said element at a pressure at most equal to ambient pressure.
