Slothbot takes a leisurely approach to environmental monitoring
For environmental monitoring, precision agriculture, infrastructure maintenance and certain security applications, slow and energy efficient can be better than fast and always needing a recharge. That's where "SlothBot" comes in.
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.
Safer electrochromic inks
Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action. Chemists have developed a new method to more safely and, by extension, easily produce these shear films, which change their color with the help of a tiny electric current. This could make them available to many industries that have not been able to feasibly use them before.
Future hypersonics could be artificially intelligent
A test launch for a hypersonic weapon — a long-range missile that flies a mile per second and faster — takes weeks of planning. So, while the U.S. and other states are racing to deploy hypersonic technologies, it remains uncertain how useful the systems will be against urgent, mobile or evolving threats.
Seeing through a robot's eyes helps those with motor impairments
An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a "robot's eye view" of surroundings to help users interact with the world through the machine.
Ultra-low power chips make small robots more capable
An ultra-low power hybrid chip inspired by the brain could help give palm-sized robots the ability to collaborate and learn from their experiences.
Charting a path to cheaper flexible solar cells
There's a lot to like about perovskite-based solar cells. They are simple and cheap to produce, offer flexibility that could unlock a wide new range of installation methods and places, and in recent years have reached energy efficiencies approaching those of traditional silicon-based cells. But figuring out how to produce perovskite-based energy devices that last longer than a couple of months has been a challenge.
Unleashing perovskites' potential for solar cells
Researchers have been able to decipher a key aspect of the behavior of perovskites made with different formulations: With certain additives there is a kind of "sweet spot" where greater amounts will enhance performance and beyond which further amounts begin to degrade it.
Scientists turn carbon emissions into useable energy
A recent study, affiliated with UNIST has developed a system that produces electricity and hydrogen while eliminating carbon dioxide, which is the main contributor of global warming.
Sun in a box would store renewable energy for the grid
Engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a small city not just when the sun is up or the wind is high, but around the clock.
Machine learning simulates everyday task of dressing
Computer scientists have devised a novel computational method, driven by machine learning techniques, to successfully and realistically simulate the multi-step process of putting on clothes.
Potential health risk from 3D printer emissions
Following an in-depth, two-year research period researchers found that many desktop 3D printers generate ultrafine particles (UFPs) while in operation. UFPs may pose a health concern since they are the size of nanoparticles and may be inhaled and penetrate deep into the human pulmonary system.
Elephant trunks inspire robotics
Understanding how elephants use their trunks to pick up small objects could lead to robots designed with flexible hands or grippers, according to a new study.
Fuel cell runs on methane at practical temperatures
Fuel cells have not been particularly known for their practicality and affordability, but that may have just changed. There's a new cell that runs on cheap fuel at temperatures comparable to automobile engines and which slashes materials costs.
Robot teaches itself how to dress people
More than 1 million Americans require daily physical assistance to get dressed because of injury, disease and advanced age. Robots could potentially help, but cloth and the human body are complex.
Origami, 3D printing merge to make complex structures in one shot
By merging origami with 21st century technology, researchers have created a one-step approach to fabricating complex origami structures whose light weight, expandability, and strength could have applications in everything from biomedical devices to equipment used in space exploration.
New material, manufacturing process, uses sun's heat for cheaper power
Researchers have developed a new material and manufacturing process that would make one way to use solar power - as heat energy - more efficient in generating electricity.
How to mass produce cell-sized robots
Tiny robots no bigger than a cell could be mass-produced using a new method. The microscopic devices, which the team calls "syncells" (short for synthetic cells), might eventually be used to monitor conditions inside an oil or gas pipeline, or to search out disease while floating through the bloodstream.
