Reversible actuation of fibrous artificial muscle under external compression load

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 12, 2025

Herein, we report hybrid fibrous artificial muscles with reversible actuation, i.e., expansion upon cooling and contraction heating, under external compression. Although many polymeric by twist insertion in precursor fibers have been developed, most of them cannot reversibly actuate without an tensile load. While heterochiral Nylon can compressive load, the stress applied is low (0.078 MPa). In this study, inserted pre-tensioned actuation into pre-compressed helical metallic spring obtained muscles. We employed two types two-way shape memory polymers, one type fishing line muscle, seven springs preparing A structural mechanics model was numerical simulation conducted to evaluate effect design parameters on strain. It found that all were free-standing (reversibly load) beyond compression load). As example, muscle actuated 24 MPa buckling. expect study will open new opportunities for use as linear actuators soft robotics or other applications need

Recent Progress in MXene‐Based Electrochemical Actuators and Capacitors

Small Structures, Journal Year: 2024, Volume and Issue: 5(5)

Published: April 4, 2024

A new family of two‐dimensional (2D) transition metal carbides, carbonitrides, and nitrides (MXenes) has attracted increasing attention owing to their electrical, chemical, physical properties. Together with various attractive properties the MXenes, they also exhibit electrochemical induced deformation (i.e., expansion/contraction) via ion intercalation/de‐intercalation in/from MXene layers. In this respect, MXenes offer possibility application as electrode actuators (ECAs). While MXene‐based ECAs are still in infancy stage, researchers have made great effort achieve high‐performance capacitors (ECs). As name suggests, both ECs shared common traits which operations based on processes. This review provides recent progress parallel that gain insights from relatively mature developments EC applications. Finally, findings previous studies applications, perspectives future terms electrode, electrolyte, cell configuration provided.
