This paper looks a lot like a materials hype paper. The mathematics for the design process are interesting, but the material/actuator itself looks pretty poor.
The actuation forces are incredibly low - if i've eyeballed correctly - around 10 micro newtons and it requires a large bulky magnetic field setup, only shown in the supplementary section.
