Polymer reversibly glows white when stretched

Researchers at the University of Fribourg's Adolphe Merkle Institute (AMI) and Hokkaido University in Japan have developed a method to tailor the properties of stress-indicating molecules that can be integrated into polymers ...

New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds ...

Marine Skin dives deeper for better monitoring

A new and greatly improved version of an electronic tag, called Marine Skin, used for monitoring marine animals could revolutionize our ability to study sea life and its natural environment, say KAUST researchers.

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.

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.
