摘要

A tubular-mold-based processing technology to prepare fibrous CLCE actuators

and the prepared actuators exhibit the capabilities to dynamically switch structural colors and geometrical shapes by mechanical

temperature

or light stimuli.

Abstract

Photonic fibrous soft actuators that can modulate light and produce responsive deformation would have broad technological implications in areas

ranging from smart textiles and intelligent artificial muscles to medical devices. However

creating such multifunctional soft actuators has proved tremendously challenging. Here

we report novel cholesteric liquid crystal elastomer (CLCE) based photonic fibrous soft actuators (PFSAs). CLCE can serve as chiral photonic soft active material and allow for multiresponse in shapes and colors. We leveraged a tubular-mold-based processing technology to prepare fibrous CLCE actuators

and the prepared actuators exhibit the capabilities to dynamically switch structural colors and geometrical shapes by mechanical

temperature

or light stimuli. CLCE-based PFSAs demonstrate diverse functionalities

including visual weight feedback

optically driven object manipulation

and light driven locomotion. It is anticipated that our PFSAs would offer many new possibilities for developing advanced soft actuators.
