Civilized explosive welding: Impact welding of thick aluminum to steel plates without explosives

Journal of Manufacturing Processes, 2018
Abstract In this paper, we report welding of 6.35 mm thick AA5052-H32 and AA1100-H14 plates to mild steel, which was achieved in a laboratory environment by vaporizing foil actuator welding (VFAW). An AA3003-H14 interlayer was used between the AA5052-H32 and the mild steel to improve weldability.

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.
