I was told there exists a metallic fluid that contracts when a voltage is applied to it. Does anything like this actually exist?

I believe the mechanism you are talking about is known as electrostriction.
https://en.wikipedia.org/wiki/Electrostriction

I do not have a good knowledge of which materials exhibit it.
I was looking for examples of electrostrictive fluids, but could only find statements about dielectric fluids. Electrostrictive change shape in an electric field, which I expects is related to polarization. I've seen examples in the past in physics or materials science texts, but they are all in storage at the moment, so I can't readily access.

You mean like this - ( Watch out for Terminator )

If not, it still is interesting.

That's really cool.

And of course they reference Landau

Thanks for the replies. If something like this does exist, I'm wondering if it would be possible to make an artificial muscle with it.
