Self‐Soldering, Stretchable and Self‐Healing Liquid Metal Elastomer Interconnections for Soft Electronics Platforms

Advanced Materials Technologies, EarlyView.
A self‐healing and electrically conductive liquid metal elastomer enables robust self‐soldering of surface mount devices for soft electronics. Photothermally activated conductive pathways, strong pressure‐sensitive adhesion, and stable package‐integrated contacts provide high conductivity and extreme stretchability.

In-situ stress distribution model in viscoelastic coal seams based on the stress relaxation effects and its application in outburst-prone coal seams

Meitan xuebao
In-situ stress is a core factor controlling dynamic gas disasters in coal mines. Existing in-situ stress models are primarily based on the elastic properties of coal-rock formations and are not suitable for viscoelastic coal media.

Microneedles Mediated Delivery of Nanodiamonds for Quantum Sensing of Free Radicals in Skin Tissue

Advanced Materials Technologies, EarlyView.
Fluorescent nanodiamonds are nanoscale sensors capable of monitoring cellular stress responses. However, to function effectively, they must be delivered into cells or tissues. Here, we demonstrate their application in the skin by developing a dissolvable microneedle platform that dissolves after skin insertion, enabling the delivery of nanodiamonds ...

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...
