Robots that can sort recycling

Every year trash companies sift through an estimated 68 million tons of recycling, which is the weight equivalent of more than 30 million cars.

MOFs can sense and sort troublesome gases

From astronauts and submariners to miners and rescue workers, people who operate in small, enclosed spaces need good air quality to work safely and effectively. Electronic sensors now developed by a KAUST team can simultaneously ...

Too many airplane systems rely on too few sensors

The apparent connection between fatal airplane crashes in Indonesia and Ethiopia centers around the failure of a single sensor. I know what that's like: A few years ago, while I was flying a Cessna 182-RG from Albany, New ...

Two-armed 3-D printing

Twin robotic arms work together as part of a project to construct what will be the largest, most complex object ever 3-D printed in titanium: a test version of the 3-m diameter 'optic bench' at the heart of ESA's Athena X-ray ...

Sensor

A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, all sensors need to be calibrated against known standards.
