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, ...

In a previous Broadcast Engineering article (“Understanding blocking capacitor effects,” August 2011), I mentioned that one of the first tasks in my broadcast engineer career was to work on optical-to ...

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 ...

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 ...

Distributed fiber-optic sensors are widely used to monitor temperature and strain in infrastructure, but their spatial resolution has long been limited. In a new study, researchers from Shibaura ...
