Sensors

Two separate, recently published studies have demonstrated how combining brain sensors and AI to create a brain-computer interface (BCI) gave two women with the inability to speak a voice. It's hoped the tech will soon be able to assist more people.

Most of us don't need special pants that let us know we're exhausted, but for hardcore athletes, such an alert could help stave off injuries. To that end, researchers created an electronic yarn that could detect fatigue based on movement patterns.

It's certainly handy to know how fast gears or wheels are spinning, but equipping them with external sensors may affect their performance. That's why scientists have devised a method of 3D-printing wireless sensors right into the things.

The US Marine Corps has decided to purchase Northrop Grumman's all-in-one Next Generation Handheld Targeting System (NGHTS) that packs a suite of day/night targeting sensors in a 10-lb (4.5-kg) package and can operate in GPS-denied areas.

Mercury can be quite harmful in large amounts, and detecting its presence in foods or liquids typically requires lab-based tests. A new nanosensor, however, can quickly detect even small levels of the heavy metal onsite, simply by tapping on samples.

Last year, Samsung demonstrated the power of its monstrous 200-megapixel camera sensor by printing a billboard-sized cat photo taken on a phone. Now the company has started mass producing its successor, the Isocell HP2.

The REM stage of sleep plays an important role in learning, memory and brain development. Currently, lab-based tests are required to gauge how much REM sleep a person is getting. The SomaSleep mask, however, is claimed to let users do so at home.

While some assistance is available to individuals who lack the power of speech, verbally communicating with other people can still be challenging. A new face-worn strain sensor could help, as it's able to "read" the wearer's silently mouthed words.

A team of engineers has developed a new type of camera that can detect radiation in terahertz wavelengths. This new imaging system can see through certain materials in high detail, which could make it useful for security scanners and other sensors.

One of the dangerous things about sports-related concussions is the fact that athletes may not realize they have one, so they don't seek medical attention. A new sensor could let them know, and it would go on their neck, not their head.

Soccer's international governing body, FIFA, has developed semi-automated offside technology that uses AI, stadium cameras and a connected match ball to assist on-field referees with offside calls at 2022 World Cup matches in Qatar.

Saab has introduced a passive, lightweight, electronic warfare sensor called Sirius Compact, which is designed to act alone or in an array to locate incoming threats on a variety of tactical levels without revealing its presence.
