This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Harnessing Discrete Differential Geometry: A Virtual Playground for the Bilayer Soft Robots
A discrete differential geometry‐based framework is developed to model the mechanics of bilayer structures with asymmetric geometry and material properties. The simulations capture dynamic bending and contact interactions in soft robotic grasping, crawling, jumping, and swimming, demonstrating the framework's versatility for programmable shape morphing

Symmetry Breaking Metamaterial Sleeve Actuators
Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.

McKibben Artificial Muscle Embedded with Stretchable Textile Sensor
A thin McKibben artificial muscle with an embedded resistive stretchable textile sensor (TES‐MAM), enabling real‐time displacement measurement without external sensors, is developed. TES‐MAM maintains a compact 4.5 mm diameter even with additional sensing components, preserves contraction performance, and provides stable resistance responses under ...
