EE INDUSTRY UPDATE

摘要

In what could be a boost to the Internet of things, University of Washington engineers have created a battery-free wireless communications system that takes advantage of what the researchers call "ambient backscatter." Shyam Gollakota, a UW assistant professor of computer science and engineering, said the researchers can repurpose ambient wireless signals into both a power source and a communications medium. Potential applications include wearable computing, smart homes, and self-sustaining sensor networks.
