Atmospheric gravity waves drive winds, temperature and chemical composition in the middle and upper atmosphere, but not enough is known about those that occur at higher altitudes. Now though, an ...

This prototype millimeter-wave radar sensor developed at UC Davis is capable of measuring extremely small vibrations and movements while being energy-efficient and cheap to produce. (Omeed Momeni/UC ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have ...

At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something ...

Researchers at Eindhoven University of Technology (TU/e) have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the ...

Engineers and architects designing new office buildings and factories are increasingly seeking improved sensors to implement a variety of energy-saving safety and security features. These sensors are ...

Researchers develop a proof-of-concept millimeter wave radar sensor that can detect extremely small vibrations and movements. Researchers at the University of California, Davis, have developed a proof ...
