A.4.4 Examples of acoustic droplet ejection
Figure A.3 shows a 5 nL droplet being ejected from a volume of water. The
acoustic energy pulse creates a mound of fluid at the surface, which is
pushed up. A droplet forms on a neck and eventually pinches off. Its
momentum carries it up to a receiving surface while the fluid mound
recedes into the larger fluid volume.
