Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics

Advanced Robotics Research, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics

Advanced Science, EarlyView.
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Microstructural Analysis of Linear Friction-Welded 718 Plus Superalloy

JOM, 2014
The microstructure of Allvac 718 Plus (718 Plus; ATI, Pittsburgh, PA, USA) superalloy was examined after linear friction welding (LFW) and after standard postweld heat treatment (PWHT). The liquid phase reaction of second-phase precipitates, which are known to constitutionally liquate during conventional fusion welding, was observed in the ...

Ionic Elastomer Interface for Low‐Pressure and Durable All‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
This work reports an ionically conductive elastomer that enables stable all‐solid‐state batteries（ASSBs）under low external pressure. The soft elastomeric matrix, integrated with a LiG3‐based conductive phase(lithium bis(trifluoromethanesulfonyl)imide and triethylene glycol dimethyl ether), simultaneously delivers high ionic conductivity and mechanical ...
