Multi‐factor influence on the properties of polymer fiber‐based artificial muscles

Abstract

Thermosensitive polymer artificial muscle fiber filaments made of two polymers, cyclic olefin copolymer elastomer (COCe) and polyethylene (PE), have the ability to sense changes generated by the external environment temperature. To optimize the thermosensitive polymer performance, this work investigates the effects of heating temperature, tensile load, strain rate, and mix proportion applied to COCe-PE polymers on mechanical properties of the resulting fiber-based muscle. The fiber filament deformation, stress distribution, and penetration characteristics are compared with multifactor coupling parameters utilizing a computational fluid dynamics simulation model. The
