Active Fabric Origami Enabled by Digital Embroidery of Magnetic Yarns

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a scalable textile manufacturing process that fabricates active origami fabrics (AFO) via digital embroidery of magnetic yarns. The programmable AFO exhibits reversible 2D and 3D transformations under magnetic fields, enabling functionalities such as altering surface roughness and linear actuation.

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

open access: yesAdvanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.

Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

open access: yesAdvanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...

Stimuli‐Responsive Materials for Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
Stimulus‐responsive materials (SRMs) hold great promise for use in a wide range of biomedical applications. This review covers four stimulus modalities, namely, electrical, optical, magnetic, and ultrasound, and their associated SRMs. It provides a summary of the materials in each modality, their development, and current research perspectives.
