Self‐Healing and Ultra‐Stretchable Hydrogel Strain Sensor Based on Poly (AAm‐co‐AMPS) for Multifunctional Biomedical Applications

open access: yesAdvanced Sensor Research, EarlyView.
A UV‐curable hydrogel strain sensor with ultrahigh stretchability (1000%), rapid self‐healing (3 s), and durability over 1000 cycles is reported. The sensor exhibits fast response/recovery (414/460 ms) and reliable motion monitoring on joints and muscles.

A Replicable and Generalizable Neuroimaging‐Based Indicator of Pain Sensitivity Across Individuals

open access: yesAdvanced Science, EarlyView.
Humans differ in their sensitivity to pain. With six large and diverse fMRI datasets (total N = 1046), this study finds that such individual differences in pain sensitivity can be tracked by fMRI responses to painful stimuli. A highly generalizable machine learning model is further built to predict pain sensitivity across all datasets and analgesic ...

Ultrahigh Seebeck Coefficient and Power Factor in Low‐Temperature Fused Ag2Se Films via Superionic‐Driven Plastic Deformation

open access: yesAdvanced Science, EarlyView.
Driven by superionic‐induced plastic deformation, low‐temperature treatment can not only effectively fuse Ag2Se nanoparticles into a dense film but also enhance thermoelectric performance by maximally preserving effective grain boundaries resulting in intensive energy filtering effect. Notably, excess Ag nanoclusters act as fusing agents, promoting the
