Dr. Christine Chapel pointing out an osmotic micro-pump
An osmotic micro-pump was a technology used by V'ger to construct the Ilia probe.
In the mid-2270s, Dr. Christine Chapel examined the Ilia probe in the USS Enterprise's sickbay and found the osmotic micro-pump inside the probe. (Star Trek: The Motion Picture)
The graphic of the osmotic micro-pump was later used as the image of the Genesis wave in Star Trek II: The Wrath of Khan.
