Polymer muscle

WebMay 11, 2024 · Twisted and coiled polymer actuators (TCPAs) are a recently discovered thermally driven artificial muscle, fabricated from a polymer fiber coiled into a helix. They produce axial contraction or torsion when heated above glass transition temperature and relaxes to their previous state when cooled back to their initial temperature. WebArtificial muscle has been a topic of intensive research for years [133–136]. The most exciting recent development is probably the discovery of polymer artificial muscle, which could contract fast and deliver large strokes (suggesting high ductility) from inexpensive high-strength polymer fibers, such as commercial fishing lines [136].
