Fiber-optic sensors work well in tight spots and in applications with a high degree of electrical noise, but care must be taken when specifying these critical components. Sensing part presence in ...

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 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.

A new fiber-optic sensor made from stretchy rubber rather than glass can be integrated into wearable electronics and measure movement. The sensors can also quantify the force of stretching, bending, ...
