Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses
Advanced Functional Materials, EarlyView.An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films
Advanced Functional Materials, EarlyView.We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Dynamic Physicochemical Gradients for Tendon–Bone Regeneration
Advanced Functional Materials, EarlyView.Dynamic physicochemical gradients offer a framework for reconnecting soft tendon and hard bone. This Review examines how hydration, transport, loading and degradation reshape these gradients during healing. Coordinating regional biological cues with progressive transfer of load from scaffold to tissue guides the design of interfaces that retain ...

Advanced Functional Materials, EarlyView.Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Advanced Healthcare Materials, EarlyView.Progressive skin expansion creates an energy crisis that compromises regenerative capacity. A self‐powered triboelectric‐hydrogel system (TP‐PAM/G) re‐couples mechanical loading with cellular metabolism by combining motion‐generated electrical stimulation and stress redistribution.
