Texoskeletons: Developing the Fundamental Technologies for Creating Intelligent Soft Robotic Clothing With Integrated 1D Sensors and Actuators

Advanced Functional Materials, EarlyView.
ABSTRACT Traditional wearable exoskeletons rely on rigid structures, which limit comfort, flexibility, and everyday usability. This work introduces the fundamental technologies to create the first soft, lightweight, intelligent textile‐based exoskeletons (Texoskeletons) built using 1D sensors and actuators.

Steel Fiber Reinforced Concrete

International Journal for Research in Applied Science and Engineering Technology, 2019
Steel Fiber Reinforced Concrete (SFRC) is a composite material that the steel fiber is evenly mixed with ordinary concrete. The steel fiber reinforced concrete is regarded as a kind of fiber strengthening system. The stress, elastic modulus and strength of steel fiber reinforced concrete are deduced by the rule of mixture.
