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, ...

United States Air Force Test Pilot School partnered with the 586th Flight Test Squadron at Holloman AFB and NASA’s Armstrong Flight Research Center to test the new use case of the AgilePod using a ...

Researchers have developed a fast and accurate flexible tactile optical sensor capable of reading Braille. The technology could enable smart readers that convert Braille to speech or text, helping to ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

In a multi-year project, researchers at Chalmers University of Technology in Sweden have developed plasmonic plastic—a type of composite material with unique optical properties that can be 3D-printed.

For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...
