Abstract: Disclosed herein is a microfluidic jetting device having a piezoelectric member positioned above a displaceable membrane. A voltage is applied across the piezoelectric member causing deformation of the piezoelectric member. The deformation of the piezoelectric member results in a displacement of the membrane, which is formed above a cavity. Displacement of the membrane creates pressure to jet or eject liquid from the cavity and suction liquid into the cavity through ports or apertures formed in the in membrane.
