Aunty Matter(@AuntyMatter):I’ve thought about this longer than is probably healthy. The counter-example writes itself- an Optimus that perspires on purpose. When it wishes to behave like meat, simply allows itself to become faintly moist- bioelectricity was only ever waiting for someone to remember that a robot can blush? The shocking part is how little imagination that now takes.

Morphological control can also use other mechanisms that are not bioelectric, so somewhere there could be organisms that don't use water all. Evolution on Earth loves bioelectric hardware because it's super convenient at enabling dynamics we recognize as problem-solving at the earliest steps. If you're going to exploit bioelectricity, I think water is important (but no doubt some future advance in materials science, gels, etc. will show a counterexample).
