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, ...

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 ...

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 ...

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. Researchers have developed a light-based technique ...

Over the past 60 years, fiber optic sensing (FOS) has been used to enhance and test the integrity, efficiency, safety, and durability of structures, vehicles, medical devices, and more across a ...

Soil is often perceived simply as "dirt," but in reality, it is a dynamic, living system that acts as Earth's natural sponge.

Microscopic sensors that are as thin as a strand of hair but capable of taking multiple measurements simultaneously could revolutionize the diagnosis and monitoring of diseases like cancer.

In the pursuit of more efficient and low-cost designs, a growing number of batteries are turning to embedded fiber-optic sensors and machine learning to optimize battery charge. The Palo Alto Research ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...
