In one of the articles I met a mention of some "piezoelectric muscles". Googled it and didn't find anything clear. I would like to know more about this decision.

What is the piezoelectric effect know? Simply put, we act on the material mechanically, and it generates current. Piezoelectric elements for lighters work like this - we press the button - a spark appears.
Piezoelectric muscles work in the opposite direction. We apply current to the material - it is mechanically deformed.

Here, read it. Muscles in this case most likely make sense of the same engine, only in robotics.
I'm afraid that you can only find it in the English literature
en.wikipedia.org/wiki/Electroactive_polymers
and see the sources there

You may not find anything for the simple reason that the technology is still new, from graphene I mean.

The principle is clear to me. I was hoping for a link to some scientific article. It seems like these muscles are made on the basis of graphene.
