To cut the cord, Eindhoven University of Technology (TU/e) researcher Hao Gao, as part of his PhD thesis, has developed a tiny transmitting temperature sensor that is powered by radio waves ...

This technology could potentially provide wireless power to sensors, LEDs and other ... enough to power simple devices, from low power radio waves. This was possible because the metamaterial ...

This makes them potential sensors. But how to detect this ... to see how the transparency varies with ambient radio waves. The signal from a simple light-sensitive photodiode then reveals the ...

Researchers at Georgia Tech have found a way to harvest energy from electromagnetic waves in the air ... Even better, the sensors that harvest the energy are simple to make.

Physicists have found a way to detect faint radio waves and convert them directly into signals that can be transmitted by fibre optics. The discovery could improve the sensitivity of detectors ...

It’s a bit of a given that lightning will be way more powerful than a simple radio wave, and lightning is a complete scattershot across a huge range of frequencies, so the millions of volts of ...

For example, traditional, light-based vision sensors such as cameras or LiDAR ... give robots superhuman vision by transforming simple radio waves into detailed, 3D views of the environment.
