Reconfigurable Metamirrors Based on Compliant Mechanisms
Advanced Functional Materials, EarlyView.Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.

3D‐Printed Soft Magnetoactive Origami Actuators
Advanced Functional Materials, EarlyView.Soft magnetoactive films are 3D‐printed using ink with up to 75 wt.% ferromagnetic particles and dual UV/heat curing, then integrated with various origami structures. The films are flexible, magnetically responsive, and programmable, enabling flexible integration with origami without hindering shape‐changeability.
