Perovskite solar cells can be made not only more robust but also more efficient, scalable and cheaper to manufacture by replacing the indium tin oxide (ITO) in the device, according to research led by the University of Surrey. The team suggests that replacing the ITO—one of the most fragile and... Read more

A new study published in Nature Communications details a hybrid robot that combines the wind-driven mobility of tumbleweeds with active quadcopter control, offering a new paradigm for energy-efficient terrestrial exploration.... Read more

Sustainability is often described in shades of green, but the future of clean energy may also carry a hint of deep blue. Electric vehicles and energy storage systems could soon draw power from a familiar pigment found in denim.... Read more

Researchers have successfully developed a high-resolution electronic skin (e-skin) device on a breathable (nanomesh) substrate using transfer technology employed in semiconductor manufacturing.... Read more

A joint research team has successfully developed a new dry-process manufacturing technology for secondary battery electrodes that overcomes the limitations of conventional electrode fabrication processes. The work is published in the journal Energy & Environmental Science.... Read more

Acoustic waves are best known as the invisible delivery agents bringing voices, car horns, or our favorite song to our ears. But the waves can also move physical objects, like an item vibrating atop a concert speaker—offering the power to turn sound into a tool.... Read more

Iron-on patches can repair clothing or add personal flair to backpacks and hats. And now they could power wearable tech, too. Researchers reporting in ACS Applied Materials & Interfaces have combined liquid metal and a heat-activated adhesive to create an electrically conductive patch that bonds to fabric when heated with...

The rise of artificial intelligence, cloud platforms, and data processing is driving a steady increase in global data center electricity consumption. While running computer servers accounts for the largest share of data center energy use, cooling systems come in second—but a new study by researchers at the National Laboratory of... Read more

Researchers at UC Santa Barbara have invented a display technology for on-screen graphics that are both visible and haptic, meaning that they can be felt via touch.... Read more

Vanderbilt researchers have developed a lightweight wearable device that shifts body armor weight off the shoulders and back of soldiers, helping reduce pain and injury risk.... Read more

Researchers at the University of Maryland, Baltimore County (UMBC) have extracted the building blocks of precise hand gestures used in the classical Indian dance form Bharatanatyam—and found a richer "alphabet" of movement compared to natural grasps. The work could improve how we teach hand movements to robots and offer humans... Read more

Watching 3D movies and TV shows is a fun and exciting experience, where images leap out of the screen. To get this effect, you usually have to wear a special pair of glasses. But that could soon be a thing of the past as scientists have developed a new display... Read more

As prominent artificial intelligence (AI) researchers eye limits to the current phase of the technology, a different approach is gaining attention: using living human brain cells as computational hardware.... Read more

In a new research project led by the Central Institute of Mental Health (CIMH) in Mannheim, scientists are investigating how insights into learning processes in animal brains can be used to make artificial intelligence (AI) systems more flexible and efficient. The project is titled NAILIt—Neuro-inspired AI for Learning and Inference... Read more

EPFL scientists have integrated discarded crustacean shells into robotic devices, leveraging the strength and flexibility of natural materials for robotic applications.... Read more
