It’s going to be extremely exciting when a group figures out artificial muscles that can be actuated electrically with high efficiency and speed.
These novel materials are fascinating, feels like modern alchemy. Even if 99% are academic vaporware.

These fibres don't seem to be actuated by electrical current, rather heat or water absorption. This makes them quite unlike muscle I would have thought.

X-ray scattering techniques seem to be a bit of a fad in recent years within many fields due in part to good availability. To a SAXS or related expert, are such experiments really necessary for a paper in this field? Was this the most efficient/straightforward to prove the crystallinity or strain? Or is it just the coolest?
Every time I read a story like this my hope that we can invent Myomer increases.
