Prestress loss in externally FRP reinforced self prestressing concrete beams [PDF]
Construction and Building Materials, 2015 Abstract Hybrid fiber-reinforced polymer (FRP) reinforced expansive concrete (EC) structural system shows a good potential for delaying concrete cracking and eliminating steel corrosion. In this study, long-term expansion-shrinkage strain development and prestress loss of the proposed system are investigated.

Autonomous Locomotion of Tensegrity Structure on Low‐Temperature Surfaces
Advanced Robotics Research, EarlyView.A low‐temperature responsive tensegrity structure (LRTS) is constructed by integrating low‐responsive temperature liquid crystal elastomer (LCE) cables, nonresponsive cables, and stiff rods. The low phase transition temperature of LCE is achieved by introducing a new liquid crystal mesogen.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.
