Coil Formation and Biomimetic Performance Characterization of Twisted Coiled Polymer Artificial Muscles

Advanced Intelligent Systems, Volume 7, Issue 2, February 2025.
This article presents a more comprehensive and reproducible test method to verify the biomimetic mechanical performance of artificial muscles. Key findings confirm linear low‐density polyethylene twisted coiled polymer actuators (TCPAs) are mechanically biomimetic artificial muscles, functioning under 60 °C.
