Optical fibers were proposed for long-distance communications about six decades ago. Soon, researchers discovered that optical fibers could also be ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230019 discusses exceptional-point-enhanced sensitivity – a new paradigm for high-sensitivity fiber sensors. The sensitivity of a ...

The inner circle classifies fiber sensors into ‘Macroscopical’ and ‘Microscopical’ according to the fiber dimension. The outer pie chart shows the classification according to the working principles.

Pipeline contents are typically valuable, volatile, and harmful to the environment if allowed to escape. With them being susceptible to aging, accidental damage, or tampering, the chances of an escape ...

Over the past decades, electronics engineers developed increasingly small, flexible and sophisticated sensors that can pick up a wide range of signals, ranging from human motions to heartrate and ...

Researchers in China have developed a rice-sized optical sensor that could give surgical robots ...
