3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.

Granular Hydrogels as Brittle Yield Stress Fluids

open access: yesAdvanced Materials, EarlyView.
This work reports the Kamani‐Donley‐Rogers yield stress fluid model can describe granular hydrogel deformation. The model robustly captures transient rheology and self‐healing behavior for granular gels of varying composition using only six parameters. This framework provides new insight regarding the effect of material parameters on granular yielding ...

Multi‐Mode Mechanochromic Responses from Cholesteric Liquid Crystal Elastomer Tubes of Uniform Sheath

open access: yesAdvanced Materials, EarlyView.
The structural‐colored tube is created from cholesteric liquid crystal elastomers, exhibiting uniform color changes with high strain sensitivity upon extension and inflation. The color change occurs across multiple mechanochromic modes, highlighting the influence of molecular anisotropy and tubular geometry on strain sensitivity.
