Thickness‐Gradient Liquid Metal Connectors for Seamless Electrophysiological Sensors
Thickness‐gradient liquid metal interfaces with elastomeric substrates enable seamless integration between ultrathin skin‐conformal electrodes and external interconnects. The mechanically compliant connector reduces interfacial mismatch and supports stable ECG/EMG monitoring under bending and motion.

Liquid‐Responsive Shape‐Memory Nanofiber‐Reinforced Scaffolds for Cartilage Repair
A liquid‐responsive shape‐memory, nanofiber‐reinforced QCG scaffold combines conformal defect filling, an aligned architecture that is structurally permissive for endogenous cell infiltration, and sustained KGN release. This integrated design enhances BMSC viability, migratory activity, and chondrogenic differentiation and promotes hyaline cartilage ...

A Robust Bio‐Supportive Hydrogel Patch for Full‐Thickness Repair of Gastroesophageal Defects
Gastroesophageal defect repair remains a formidable clinical challenge plagued by high leakage and life‐threatening complications. We develop a double‐disc, highly crystalline PVA‐based RBS hydrogel patch featuring suture‐free sealing, robust acid/enzyme resistance and mechanical durability.

Inspired by the insect campaniform sensillum, a heterogeneous bilayer strain sensor is developed based on a unique impedance mismatch and three‐dimensional structural dynamic percolation strategy. The sensor enables real‐time multi‐joint teleoperation of three joints and the gripper using a six‐degree‐of‐freedom robotic‐arm platform.

Self‐Responsive Plastron Maintenance on a Superhydrophobic Mesh via Locally Integrated Electrolysis
This work presents a self‐switchable SHM‐E surface that enables rapid, autonomous plastron self‐repair and long‐term stability. Plastron loss triggers circuit closure and localized electrolysis, while capillary spreading rapidly restores a continuous plastron and self‐terminates the current.

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Stress interference in multilayer additive friction stir deposition of AA6061 aluminum
Abstract Due to the multilayer deposition nature of metal additive manufacturing processes, each layer being printed experiences the state of thermokinetic and thermomechanical stress that in turn interfere with the state of thermokinetics and thermomechanical stress of subsequently deposited layers.
