Artificial “muscles” achieve powerful pulling force

This appears to be two materials bonded together who expand at different temperatures causing a coiling effect vs a single material changing properties.

The 2014 University of Texas example is also two materials - "fishing line and sewing thread", so the unique is this new research is something else.

The University of Texas approach was fishing line OR sewing thread. (Just a twisted single-material polymer line.)

At the start of this MIT article, I was wondering if it was just a re-hash of the fishing-line 'muscle' discovery as well.

But it's clear that the MIT muscle coils up because of the difference in thermal expansion between two bonded materials, while the Texas one seems to be more about a coiling pattern that multiplies the effect of a thermal expansion or contraction of a single material.

Hmm, yes. Re-reading the synopsis, I can see I was mislead by the heading.
