Finalists Announced for 2019 R&D 100 Awards
Finalists for the venerable R&D 100 Awards have been announced by R&D World magazine and its new parent company, WTWH Media, LLC.
Material for Safer Football Helmets May Reduce Head Injuries
Scientists have developed elastic microlattice pads that can withstand both single hits and a series of impacts better than existing state-of-the-art foams used in football helmets. Their research suggests that the material may pave the way for helmets that better protect football players and other athletes from brain injuries caused by repeated head hits.
Army researchers test human-like robots
Army researchers tested ground robots performing military-style exercises, much like Soldier counterparts, at a robotics testing site in Pennsylvania recently as part of a 10-year research project designed to push the research boundaries in robotics and autonomy.
Shape-shifting robots built from 'smarticles'
Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as "smarticles" to unlock the principles of a potentially new locomotion technique.
Study identifies main culprit behind lithium metal battery failure
A research team has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access.
US Army wants world's largest, fastest metal powder 3D printer
This printer will revolutionize key supply chains associated with long-range munitions, next-generation combat vehicles, helicopters, and air and missile defense capabilities.
Army project develops agile scouting robots
Researchers have developed an agile robot that may be able to aid in scouting and search-and-rescue operations.
Army discovery opens path to safer batteries
Soldiers carrying 15-25 pounds of batteries could carry batteries a fraction of the weight but with the same energy and improved safety, a new study shows.
Converting Wi-Fi signals to electricity with new 2-D materials
Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers from MIT and elsewhere have taken a step in that direction, with the first fully flexible device that can convert energy from Wi-Fi signals into electricity that could power electronics.
Small flying robots haul heavy loads
A closed door is just one of many obstacles that poses no barrier to a new type of flying, micro, tugging robot called a FlyCroTug. Outfitted with advanced gripping technologies and the ability to move and pull on objects around it, two FlyCroTugs can jointly lasso the door handle and heave the door open.
World's first 3D volumetric circuit
Research on the 3D/volumetric circuit technology was borne out of the notion that a three-dimensional circuit offers more freedom to make circuits smaller, lighter and more efficient. 3D printing allows them to be manufactured into arbitrary form factors that can be integrated into any object or surface.
If military robot falls, it can get itself up
Scientists at the U.S. Army Research Laboratory and the Johns Hopkins University Applied Physics Laboratory have developed software to ensure that if a robot falls, it can get itself back up, meaning future military robots will be less reliant on their Soldier handlers.
Water bottles and other recycled 3D printing materials
Soldiers on the battlefield or at remote bases often have to wait weeks for vital replacement parts. Now scientists report they have found a way to fabricate many of these parts within hours under combat conditions using water bottles, cardboard and other recyclable materials.
Introducing the latest in textiles: Soft hardware
The latest development in textiles and fibers is a kind of soft hardware that you can wear: cloth that has electronic devices built right into it.
A higher-energy, safer and longer-lasting zinc battery
A team of researchers has created a water-based zinc battery that is simultaneously powerful, rechargeable, and intrinsically safe.
Invertebrates inspire first fully 3-D printed active materials
To overcome the material rigidity and actuation limitations in current robotic systems, a joint U.S. Army Research Laboratory and University of Minnesota research project sought inspiration from invertebrates.
Scientists mimic neural tissue
Researchers have discovered a process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue. The breakthrough material may lead to autonomous soft robotics, dual sensors and actuators for soft exoskeletons, or artificial skins.
