Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling
Advanced Functional Materials, EarlyView.Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...
