Figure 1. Photothermal synergistic TPP hydrogen detection system integrated at the tip of an optical fiber. (a) A 3D schematic of the fiber-optic TPP tip illuminated simultaneously by a halogen light ...

Due to the trend of miniaturization of devices, micromanipulation has been a hot topic in the last two decades. Unlike the macro world, the micro object can easily be damaged if the contact force is ...

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, ...

Broken rails or damaged wheels can cause train accidents with potential loss of life, injury or property damage. Researchers at the University of Illinois are fabricating fiber-optic sensors that can ...

Most people know that light travels in a straight line unless something acts upon it to change its direction. The three most common methods of changing the direction of light are refraction, ...

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 ...
