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 ...

INVESTIGATION ON CORROSION RATE OF BUTT-JOINT IN GAS METAL ARC WELDING, FLUX CORE ARC WELDING AND SUBMERSIBLE ARC WELDING

Jurnal Teknologi, 2015
Corrosion can be defined as the destructive attack of a metal through interaction with its environment. Different type of welding can be factors that contribute to the corrosion and erosion problems since this type of welding will lead the material to expose with the corrosion and erosion agents like salt, air , water and material composition ...

Hierarchical Reconfigurable Metasurface Based on Scenario‐Guided Functional Modules and Programmable Core

Advanced Science, EarlyView.
This paper proposes a hierarchical reconfigurable metasurface architecture (HRMA) to achieve comprehensive electromagnetic parameter modulation and on‐demand polymorphic function switching. The reconfigurable metasurface is divided into a programmable core (PC) and scenario‐guided functional modules (FMs), exhibiting significant flexibility and ...
