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

ABSTRACT:

Objective

A biological muscle's force is nonlinearly constrained by its current state (force, length, and speed) and state history. To investigate if artificial muscles can mimic the complete mechanical state spectrum of biological muscles, this study uses a novel method to characterize twisted coiled polymer actuators (TCPAs) mechanically. Thus, comprehensive and reproducible test procedures are established to verify artificial muscle biomimetics regarding stress, strain, and strain rate combinations intrinsic to biological muscle.

Approach

A rheometer performs novel high-precision mechanical characterization methods that comprehensively verify biomimetic performance. Sample twist level, torque, length, force, and temperature were controlled and measured during twist-induce
