In the future, smart clothing might monitor our posture, communicate with smartphones and manage our body temperature. But first, scientists need to find a way to cost-effectively print intricate, flexible and durable circuits onto a variety of fabrics. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a conductive 3D printing ink made of liquid metal droplets coated with alginate, a polymer derived from algae.

Conventional electronics are rigid and unable to withstand the twisting and stretching motions that clothing undergoes during typical daily activities. Because of their fluid nature and excellent conductivity, gallium-based liquid metals (LMs) are promising materials for flexible electronics. However, LMs don’t stick well to fabrics, and their large surface tension causes them to ball up during 3D printing, rather than form continuous circuits. Yong He and colleagues wanted to develop a new type of conductive ink that could be 3D printed directly onto clothing in complex patterns.

Airbus has completed wind-tunnel testing of its eXtra Performance Wing demonstrator in its quest to quickly test and accelerate advanced innovative technologies that will decarbonize the aviation industry. The demonstrator model was tested in the Filton wind tunnel near Bristol, England.

Launched last September, the eXtra Performance Wing project takes inspiration from nature to improve wing aerodynamics and performance. It is intended to be compatible with any future aircraft configuration and propulsion system to reduce CO₂ emissions.

To make a more efficient aircraft with lower carbon footprints, Airbus is testing wing technologies that are based on the behavior of bird flight with wings. Initially, the technology was introduced at a smaller scale through another Airbus project, AlbatrossONE, which tested semi-aeroelastic hinged wings that – like the seabird – unlocked during the flight when experiencing wind gusts or turbulence. Now, the eXtra Performance Wing will also examine new technologies, including gust sensors, pop-up spoilers, and multifunctional trailing edges to enable active control of the wing.

A simple colour change could indicate the presence of potentially hazardous hydrogen gas thanks to a new sensor developed by researchers in Germany. The micron-scale device, which uses so-called “supraparticles” that turn from purple to pink in the presence of hydrogen, could help prevent explosions by making it easier to detect and localize leaks at fuel stations, generators and pipelines.
