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, ...

The recent development in the utilization of flexible optical fiber sensors and the prospective application scenarios were then summarized, which encompass human activity monitoring and healthcare, ...

Optical fiber-based sensors have been around since the 1990s for experimental stress analysis. With technology refinements, the fiber Bragg grating (FBG) sensors of today are highly compatible with ...

DARPA has succeeded in creating hollow-core photonic-bandgap optical fiber, which allows light to travel along its length at around 99.7% the speed of light, or a 30% improvement over conventional ...
