World's 'Smallest Magnifying Glass' Supports New Sensors

Using tiny particles of gold, researchers from the University of Cambridge have concentrated light to smaller than a single atom. By focusing the light to just under a millionth of a meter, the scientists have a "magnifying glass" that reveals individual chemical bonds within molecules.

Ultrasensitive Sensors Keep Driverless Cars Safer

Sensor chips are implemented in CMOS technology. (© Photo Fraunhofer IMS) News of the first serious accident involving an automated electric vehicle made headlines recently. Researchers are counting on light detection and ranging (LiDAR) technology, in combination with other components, to fulfill the requirements for independent steering, braking, and acceleration.

Military Sensor Inspires Instrument to Search for Life on Mars

This artist’s rendition shows how BILI could operate on Mars. (NASA) A sensing technique used by the U.S. military currently to remotely monitor the air to detect potentially life-threatening chemicals, toxins, and pathogens has inspired a new instrument that could “sniff” for life on Mars and other targets in the solar system.

New System Allows Buildings to 'Sense' Internal Damage

Researchers at the Massachusetts Institute of Technology have developed a computational model that makes sense of the ambient vibrations that travel up a structure as trucks and other forces rumble by. By picking out specific features in the noise that give indications of a building’s stability, the model may be used to continuously monitor a building for signs of damage or mechanical stress.

'Proximity Hat' Reveals Surroundings in Real Time

Karlsruhe Institute of Technology (KIT) researchers have developed a "Proximity Hat" that uses head pressure to inform users about their surroundings. The ultrasonic sensors, batteries, and pressure pads can be worn like a hat or headband.

Gamma-Ray Spectroscope Supports Asteroid Mining Missions

A new gamma-ray spectroscope detects the veins of gold, platinum, and rare earths hidden within the asteroids, moons, and other airless objects floating around the solar system. The sensor, developed by teams at Vanderbilt and Fisk Universities, NASA’s Jet Propulsion Laboratory, and the Planetary Science Institute, will allow miners to find valuable materials beyond Earth.

Depth-Sensing Camera Works in Bright Light and Darkness

A new imaging technology from Carnegie Mellon University and the University of Toronto operates in both bright sunlight and darkness. A mathematical model programs the device so that the camera and its light source work together efficiently, eliminating extraneous light, or “noise,” that would otherwise wash out the signals needed to detect a scene’s contours.
