Mechanically activated liquid metal powder lets users draw circuits on paper
What if electronic circuits could be created simply by drawing lines with a pencil on paper or leaves—and then immediately applied to soft robots or skin-attached health monitoring devices? Korean researchers have developed an electronic materials technology that forms electrically conductive liquid metal in a fine powder form, allowing circuits... Read more

Sulfide coating boosts lithium-ion battery lifespan past 1,000 cycles
Among the biggest complaints inhibiting growth in the electric vehicle market is the limited lifespan and range of lithium-ion batteries. Consumers fear being stranded far from home with long wait times at recharging stations. A promising area of research has focused on layer-structured metal oxide cathodes. Specifically, a material known... Read more

A microphone that can sort sounds and measure noise could be coming to a construction site near you
Do you want to know how much noise there is on a construction site? You want to measure the sound of the excavator or the hammer drill, but you don't want to measure seagulls, traffic noise or a helicopter flying by. Now a new sound measurement service can do just... Read more

How an acid found in grapes could help recycle battery metals
Cobalt and nickel are vital components for batteries, superalloys and catalysts, used in technologies ranging from smartphones to jet engines. But when it comes to recycling, they are notoriously difficult to separate because they are chemically nearly identical. To solve this, a team led by scientists at Johns Hopkins University...

Dripping paint: Research resolves annoyance that hindered Michelangelo's 'The Creation of Adam'
More than 500 years ago, Michelangelo spent four years painting "The Creation of Adam" on the ceiling of the Sistine Chapel, struggling with paint dripping onto his face. He described the process as "closer to torture than painting." Now, researchers at KAIST have developed a technology that can effectively "hold... Read more

A night vision upgrade: How AI-tuned VO₂ films could make infrared cameras far more sensitive
Inspired by the infrared sensory organs of snakes, which allow them to detect prey in complete darkness, researchers at UNIST have harnessed artificial intelligence (AI) to develop a sensor material that significantly enhances thermal detection capabilities. This advancement promises to elevate the performance of next-generation infrared cameras, night-vision systems for... Read more

Biohybrid image sensor uses water-based electrolyte to mimic retina's rods and cones
Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical signals to either a graphical interface of a display or the brain. Image sensors rely on solid state semiconductor technology, whereas retinas rely on photoreceptor cells... Read more

Aerosol jet printing creates durable, low-power transistors for next-generation tech
Tiny electronic devices, called microelectronics, may one day be printed as easily as words on a page, thanks to new research from scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory. Building on years of progress in printed electronics, the team has shown how to create durable, low-power... Read more

For precision tech, a hydrogen-tuned crystal could cancel thermal expansion
Scientists from Tokyo Metropolitan University have discovered that a hydrogen-absorbing material shrinks in one direction upon heating, so-called negative thermal expansion (NTE). They found that this NTE is driven by a phase transition in the alignment of magnetic moments, an entirely different mechanism from its hydrogen-free counterpart. The research is... Read more

Multiply and subtract your way to more lifelike VR avatars
POSTECH's (Pohang University of Science and Technology) Professor Inseok Hwang's team has developed ArithMotion, a mobile virtual reality (VR) system that enables anyone to express a wide range of avatar motions with ease. Using simple arithmetic-like controls, users can scale an avatar's motion up or down and reverse it into... Read more

Your clothes may become smarter than you
You're probably used to the sight of smartwatches on people's wrists. But what about smart clothes? Researchers at the University of Georgia are exploring how the clothes people wear can potentially track and protect their health. Smart textiles are fabrics that can monitor the body's vitals and movement in real... Read more

Liquid-metal pupil helps an artificial eye adapt to sudden light changes
Computer vision technologies are artificial intelligence (AI)-powered systems that can capture, analyze, and interpret visual data captured from real-world environments. While these systems are now widely used, many of them perform poorly under some lighting conditions and when the light in captured scenes changes abruptly.... Read more
