Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

open access: yesAdvanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.

In Situ Two‐Dimensional Residual Stress Characterization of Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals

open access: yesAdvanced Optical Materials, EarlyView.
Ion‐driven electrohydrodynamic effects enable dynamic photonic bandgap modulation in cholesteric liquid crystals under low‐frequency AC driving. By regulating ion‐mediated disturbance of the helical structure, this approach produces two reversible optical responses: rapid color shifting across the visible spectrum and broadband reflection spanning the ...

Nanopatterned Dual‐Carbon‐Dot Photonic Films With Enhanced Light Outcoupling

open access: yesAdvanced Optical Materials, EarlyView.
Nanoimprinted dual‐carbon‐dot/PVA films combine composition‐tunable blue–green emission with grating‐mediated directional light outcoupling. Water‐processable B‐CD and G‐CD composites are patterned by drying‐assisted nanoimprinting, producing angle‐selective emission peaks that follow the first‐order diffraction condition and exhibit reference ...
