A Tangentially Sensitive Tactile Sensor Reveals the Stick‐Slip Mechanism and Enhances Robotic Tactile Sensing

Advanced Science, EarlyView.
An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Electric‐Fish‐Inspired Thin Hydrogel Electrocytes Achieve High Power Density and Environmental Robustness

Advanced Science, EarlyView.
This study presents thin, environmentally stable hydrogel power sources inspired by electric fish. Made using layer‐by‐layer spin‐coating with glycerol‐enhanced solutions, they offer precise layer control, long‐term hydration, and anti‐freezing stability.

Cross‐Platform Biosensing of Immune Receptors Using Peptide‐Functionalized Graphene

Advanced Science, EarlyView.
A peptide‐functionalized graphene biosensor enables sensitive and selective detection of living immune cells. Targeting Formyl‐Peptide Receptor 2 (FPR2), the assay is demonstrated on model cells and primary human neutrophils. The same assay is applied to two complementary platforms: graphene‐enhanced surface plasmon resonance for optical benchmarking ...

Tough and Temperature‐Resistant Material Based on Bombyx mori Silk Fibroin

Advanced Science, EarlyView.
We propose a biomimetic “Hydration‐Crystallization Locking” (HCL) strategy inspired by Bombyx mori spinning to enhance silk fibroin (SF) performance in extreme temperatures. A flexible fibroin membrane (FFM) shows high strength, toughness, and shape retention under −196°C and 70°C.
