Abstract
Multiscale modeling framework of polymeric artificial muscle fabricated through twisting and coiling of precursor polymeric fibers are discussed in this article. The activation mechanism in the precursor polymeric fibers is either through negative coefficient of thermal expansion such as fishing lines or sewing threads, or two-way shape memory effect, particularly using semicrystalline two-way shape memory polymers. In this article, we will introduce some of the previously developed phenomenological constitutive modeling frameworks for the artificial muscles and our physical understanding of their actuation mechanisms. We hope this work will help helps readers better understand the historical development in twisted-then-coiled polymeric artificial muscles in general, and multiscale modeling frameworks in particular.
