A new generation of optical sensors is enabling the development of robust, long-lasting, lightning-fast trace gas detectors for use in a wide range of industrial, security and domestic applications. A ...

It is estimated that around 8,000 people are killed by landslides every year, while many others narrowly escape the terrifying ordeal. But now a new way of predicting landslides has been developed – ...

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 ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...

Researchers have developed a new way to recognize human emotions by combining fiber-based physiological signals with thermal ...

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, ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
