Abstract
A microfluidic actuator suitable for effecting drop on demand inkjet printing by ejecting fluid through at least one nozzle from at least one cavity being at least partially formed by a deflectable membrane, the actuator including: an actuator chamber operatively coupled to the membrane and containing at least on electrolytic fluid; and, at least one nanostructure contained in the electrolytic fluid; and, wherein, the nanostructure is adapted to deflect toward the membrane in response to an operating voltage being applied to at least the nanostructure thereby deflecting the membrane and causing the fluid to be ejected through the nozzle.
