Patterning Method for Fiber Based Devices, Smart Textiles
Multimaterial fibers that integrate metal, glass and semiconductors could be useful for applications such as biomedicine, smart textiles and robotics. But because the fibers are composed of the same materials along their lengths, it is difficult to position functional elements, such as electrodes or sensors, at specific locations.

Engineers Print Wearable Sensors Directly on Skin Without Heat
Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Microbots to Kill and Clean Biofilms
Biofilms -- microbial communities that form slimy layers on surfaces -- are difficult to treat and remove, often because the microbes release molecules that block the entry of antibiotics and other therapies. Now, researchers have made magnetically propelled microbots derived from tea buds, which they call "T-Budbots," that can dislodge biofilms, release an antibiotic to kill bacteria, and clean away the debris.

Rapid 3D Printing with Visible Light
3D printing has driven innovations in fields ranging from art to aerospace to medicine. However, the high-energy ultraviolet light used in most 3D printers to cure liquid resins into solid objects limits the technique's applications.

Anti-Bacterial Graphene Face Masks
Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes.

3D Printing Greener Buildings Using Local Soil
The construction industry is currently facing two major challenges: the demand for sustainable infrastructure and the need to repair deteriorating buildings, bridges and roads. Researchers report progress toward a sustainable building material made from local soil, using a 3D printer to create a load-bearing structure.

Flame-Retardant, Insect Repelling Fabric for Soldiers
Using methods to measure heat release capacity and total heat release, as well as a vertical flame test, they found that the modified material performed at least 20% better than the untreated material. They also used a standard insect repellency test with live mosquitoes and found that the efficacy was greater than 98%. Finally, the fabric remained "breathable" after treatment as determined by air permeability studies.

3D Printed Batteries Handle the Squeeze
While flexible and stretchable electronics technologies have progressed in leaps and bounds over the past 10 years, batteries to power them have some catching up to do. Researchers have now demonstrated a "quasi-solid-state" battery—made from materials somewhere between a liquid and a solid—that can be compressed by as much as 60% while maintaining high energy density and good stability over 10,000 charge-recharge cycles.
