Wireless Acousto‐Piezoelectric Conduit with Aligned Nanofibers for Neural Regeneration

Advanced Materials, EarlyView.
An ultrasound‐driven, highly aligned piezoelectric nanofiber‐based nerve guidance conduit (APNF‐NGC) designed for effective peripheral nerve repair has been demonstrated in this study. Featuring aligned topology, cell‐adhesive surfaces, and an axial electric field, the APNF‐NGC collectively promotes significant nerve regeneration.

How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, EarlyView.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Active Fabric Origami Enabled by Digital Embroidery of Magnetic Yarns

Advanced 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

Advanced 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.
