A string of fiber-optic sensors running along a 36-km stretch of high-speed commuter railroad lines connecting Hong Kong to mainland China has taken more than 10 million measurements over the past few ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

A research team at Hong Kong Polytechnic University has developed optical fibre sensors used in railway safety monitoring technologies for health monitoring. In a statement, PolyU described the novel ...

Monitoring the partial pressure of hydrogen in a cheap and reliable way is essential for its implementation as an energy vector. Optical sensors have a particular safety benefit due to the lack of ...

In 1978, Dr Kenneth Hill, a Canadian physicist, first demonstrated the Fiber Bragg grating (FBG), an optical sensor able to reflect narrow wavelengths of light. During the 1980s, the technology was ...

From autonomous vehicles to optical testing, these sensors bring high performance infrared detection into real-world systems.

Until recently, standard fire detectors relied on a single sensor to detect the presence of heat or smoke to determine if there was a nearby fire. As many homeowners and facility managers can attest, ...
