A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional cuff. The technology is ...
Counterfeit or low-quality products—such as olive oil made from dyed rapeseed oil—are often difficult or impossible to identify at a glance. A mobile gas chromatography sensor system is now being developed to help detect ...
From cells that migrate to tissues that heal, nature abounds with systems capable of sensing and adapting to their surroundings. Replicating this level of adaptability in synthetic systems has remained a grand challenge in ...
Quantum defects are tiny imperfections in solid crystal lattices that can trap individual electrons and their "spin" (i.e., the internal angular momentum of particles). These defects are central to the functioning of various ...
Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair. The research is published ...
For the past five years, researchers at Leipzig University have been working on fundamentally new methods for selectively assembling gaseous, charged molecular fragments into new, complex molecules. The synthesized substances ...
In the "Mission: Impossible" films, superspy Ethan Hunt—played by Tom Cruise—gets orders from his superiors on various devices that self-destruct in five seconds. Could electronics disintegrate into nothing in real life? ...
Resonantly tunable quantum cascade lasers (QCLs) are high-performance laser light sources for a wide range of spectroscopy applications in the mid-infrared (MIR) range. Their high brilliance enables minimal measurement times ...
Blood vessels are like big-city highways; full of curves, branches, merges, and congestion. Yet for years, lab models replicated vessels like straight, simple roads.
Microelectromechanical system (MEMS) optical modulators are crucial in next-generation technologies such as free-space optical communication and LiDAR, but existing designs struggle with balancing aperture size, efficiency, ...
