Enhanced antibacterial response in Zn-modified additively manufactured NiTi alloy

, 2023
In this work a superelastic NiTi alloy with improved antibacterial behavior was manufactured via Laser Powder Bed Fusion (LPBF) process. In details, NiTi and Zn powders were premixed for printing fully dense samples. It was found that the presence of Zn (

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.
