1. An ejector device for delivering a fluid to a target, the device comprising:
- a housing;
a reservoir disposed within the housing for receiving a volume of fluid; and
an ejector mechanism in fluid communication with the reservoir and configured to eject a stream of droplets, the ejector mechanism comprising an ejector plate coupled to a generator plate and a piezoelectric actuator;
the generator plate including a plurality of openings formed through its thickness; and
the piezoelectric actuator being operable to oscillate the ejector plate, and thereby the generator plate, at a frequency and generate a directed stream of droplets.
