Abstract: In this article, a fiber-optic hydrogen sensor based on a cascaded Fabry–Perot interferometer (FPI) structure and vernier effect is proposed and experimented. The sensor is mainly composed ...

At NVIDIA GTC 2025, Barco will present its latest advancements in surgical technology, focusing on AI-powered displays and computing platforms sp ...

(Photo: Mikael Nyberg) Nanotubes are often used to make hybrid sensors by combining them with another surfactant, but in this study the sensor was made completely from nanotubes. In addition, the ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

One important change is a new laptop battery indicator that visualizes the charge level with new symbols. This change was actually supposed to be implemented last month, but the release was ...

Scientists at The University of Manchester have unveiled a hydrogen ... and reversible at room temperature up to 120°C, making it ideal for real-world applications. The sensor has already been ...

“The ability to measure currents accurately while minimizing interference makes this sensor a promising candidate for monitoring battery systems in electric vehicles, where precision and reliabi ...

The sensor operates using a process called p-doping, where oxygen molecules increase the concentration of positive electrical charges in the active material. When hydrogen is present, it reacts with ...

Splitting water molecules takes more energy than calculations suggest, and is a key roadblock to cheap hydrogen fuel production. Now, scientists have discovered why.

Hydrogen sensor. Credit: Thomas Anthopoulos. As the world moves toward cleaner energy, hydrogen is seen as a key alternative to fossil fuels. However, hydrogen is clear, odorless, and highly ...
