Kresling Origami‐Based Metamaterial Robot for Dynamic Electromagnetic Control
Advanced Science, EarlyView.A reconfigurable metamaterial system integrates deformable origami units with high‐permittivity ceramic plates. Pneumatic switching between structural states alters local resonance conditions, enabling dynamic radar stealth and adaptive microwave reflection for mobile communication.

Advanced Science, EarlyView.This work presents an origami metamaterial that integrates a low‐melting‐point alloy skeleton into an elastomeric shell. It dissipates energy through the metal's plastic deformation and recovers through the solid–liquid phase transition of the alloy together with the hyperelasticity of the shell.

Advanced Science, EarlyView.Different kirigami patterns are proposed and the parameters are optimized by comparing the out‐of‐plane deformation behavior. Then, the proposed patterns are fabricated on PVDF film using laser technology. The deformed kirigami‐cut PVDF is embedded into PDMS to construct pressure senor.

Advanced Science, EarlyView.Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami
Advanced Science, EarlyView.A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.
