Jellyfish inspire flexible pumps

Jellyfish inspire flexible pumps: "Nawroth has also observed how tiny juvenile moon jellies take advantage of a layer of water that adheres to their outer surface, using it to close the gaps between their lappets (“arms”), so that their bodies are able to act more like a paddle and less like a sieve. Additionally, it has been noted that they have a network of neuronal “pacemakers” throughout their bodies, that allow them to control their contractions, according to the conditions. If such a system could be reproduced using human technology, it could allow for flexible pumps with consistent yet tunable performance."
