Most of the devices and sensors connecting to the Internet of Things (IoT) rely on transmitting radio waves to communicate, which requires power, which means batteries if mains power isn't an option.

Ambient IoT could enable smarter cities and seamless real-time data, but global challenges in power, security, identity and ...

At CES, we saw Samsung show off a TV remote that powers itself with nearby wireless waves, eliminating the need to even have a battery. While our own A/V Editor Phil Nickinson is skeptical about the ...

A team of researchers from Stanford University and the University of California, Berkeley, has created prototype radio-on-a-chip communications devices that are powered by ambient radio waves.

The moment you need to send an urgent text is usually the same moment your battery dies. But now U.S. engineers claim to have developed a solution that allows you to generate power using 'thin air.' ...

Internet of things (IoT) systems usually link networks of sensors via radio, but radios demand battery power thus limiting usability. Disney Research has determined that one solution may be to get rid ...

(Nanowerk News) Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in ...

Abstract: Traditional active radars transmit a powerful electromagnetic pulse and record the echo's delay time and power to measure target properties of interest, such as range, velocity, and ...

Seemingly every connected device has at least one wireless radio in it. However, that often requires some big compromises. Those radios often chew up a lot of power, which isn't always practical with ...
