Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism

Advanced Robotics Research, EarlyView.
Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and

Anisotropic behavior of frictional performance of aligned carbon nanotubes/styrene butadiene rubber composites

Cailiao gongcheng
The oriented nanotubes reinforced styrene butadiene rubber (CNTs/SBR) composites were prepared by applying the mechanical shear induction method, and the laws of carbon tube content and orientation on the mechanical and tribological properties of the ...

In Situ Stress‐Dispersing Hydrogel Millispheres via Load Redistribution to Restore Nucleus Pulposus Metabolic Homeostasis

Advanced Science, EarlyView.
Local stress concentration disrupts metabolic homeostasis and induces inflammation in the nucleus pulposus (NP), thereby accelerating intervertebral disc degeneration (IDD). A biomimetic HA/ChS hydrogel millimeter sphere (ChS@HM) is developed to enable synergistic stress dispersion and sustained hydration lubrication.
