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 ...

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 ...

For continuously gathering information on ocean conditions, one thing that's been proposed is a network of sensors that would transmit data from the sea floor. Changing their batteries, however, could ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

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 ...

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 ...
