Tech Xplore / Alive or not? Tiny 3D-printed robots that swim and navigate just like animals
Leiden researchers Professor Daniela Kraft and Mengshi Wei have created microscopic robots that move without sensors, software, or external control. Instead, their behavior emerges entirely from their shape and the way they ...
Tech Xplore / Molecular umbrella can protect solar cells by blocking ion migration
Perovskites are semiconducting materials that have rapidly transformed the field of optoelectronics, demonstrating outstanding performance in light-emitting diodes (LEDs) and photodiodes. For their unique properties, they ...
Tech Xplore / Integrated strategy unlocks 29.76% efficiency for all-perovskite tandem solar cells
Two stacked layers comprise tandem solar cells (TSCs), with each subcell absorbing different wavelengths of sunlight, which makes TSCs more efficient than single-layer solar cells. All-perovskite TSCs hold great promise for ...
Tech Xplore / Scheimpflug cameras may extend LiDAR-like sensing from 6 m to 4 km
An optical principle discovered more than a century ago may soon find new applications in such areas as monitoring atmospheric turbulence, tracking airborne objects, and mapping the environment, thanks to researchers at the ...
Tech Xplore / Holographic storage approach packs more data into the same space by encoding three properties of light
Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by combining three properties of light—amplitude, phase and polarization. By allowing more data to be ...
Tech Xplore / ChatGPT's taste for literary nonsense sparks alarm
OpenAI's GPT models can often be fooled into declaring that "pseudo-literary" nonsense is great, a German researcher has found.
Tech Xplore / Bat-inspired ultrasound helps palm-sized drones navigate fog and smoke
A team led by Worcester Polytechnic Institute (WPI) researcher Nitin J. Sanket has shown that ultrasound sensors and a form of artificial intelligence (AI) can enable palm-sized aerial robots to navigate with limited power ...
Tech Xplore / Video-based AI gives robots a visual imagination
In a major step toward more adaptable and intuitive machines, Kempner Institute Investigator Yilun Du and his collaborators have unveiled a new kind of artificial intelligence system that lets robots "envision" their actions ...
Tech Xplore / AI overly affirms users asking for personal advice, study finds
In a new study published in Science, Stanford computer scientists showed that artificial intelligence large language models are overly agreeable, or sycophantic, when users solicit advice on interpersonal dilemmas. Even when ...
Tech Xplore / Efficient carbon capture 'viciazite' materials can desorb below 60°C
Capturing carbon dioxide (CO2) before it reaches the atmosphere is a key strategy for reducing greenhouse gas emissions. Even though carbon capture technologies have existed for decades, their widespread adoption has been ...
Tech Xplore / Smart yarn tracks muscle activity in the body
Created from noise-resistant, conductive threads, a high-tech new smart fabric could find uses in health monitoring, sports performance and rehabilitation. The work is published in the journal Science Advances.
Tech Xplore / Web application turns indoor green walls into smart, living systems breathing life into buildings
Step into a modern office tower or hospital, and the air you breathe is often carefully engineered, filtered, circulated, and cooled at a high energy cost. Now imagine those same spaces quietly breathing on their own, supported ...
