The system scavenges power from the wireless transmitting devices around it
Researchers have developed a wireless system that directly powers Wi-Fi connections using RF backscatter
The power is sourced via RF Wi-Fi backscatter
One of the advantages of the "connected world" is that myriad different devices can interact with each other over Wi-Fi to exchange data, control equipment, and generally lay the foundations of the Internet of Things of the not-too-distant future. Unfortunately, on the downside, all of the Wi-Fi connections need power to operate, and this severely restricts the pervasiveness of this technology. However, researchers at the University of Washington have developed a system that they say eliminates the need for power supplies for these connections by using what is known as radio frequency (RF) backscatter technology.
