Sensing part presence in machines, in fixtures, and on conveyors is an important component of industrial automation. Error-proofing assembly and controlling sequence based on presence or absence of a ...

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, ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Designers of composites are learning that if they are to be able to guarantee component and system performance, repeatability and reliability, it is critical that they have access to more sensor and ...

Fiber optic sensors - used in critical applications like detecting fires in tunnels, pinpointing leaks in pipelines and predicting landslides - are about to get even faster and more accurate. EPFL ...

Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws -- and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban ...
