New battery charging system allows for Wi-Fi – Metro Chile

A team of researchers from the University of Washington in Seattle, USA, began testing for charging a router via Wi-Fi networks at distances of up to 8.5 meters.

team managed to power devices that use small appliances and remote controls, such as nickel-metal hydride and small batteries lithium ion watches.

The Spanish newspaper El Pais reported that the study was reported in Technological Reviewen MIT magazine, an article of 14 pages under the title “Feeding the next billion Wi-Fi devices.”

The system collects energy supply network and so continues to batteries, representing “significant progress” to keep fed all kinds of low-power sensors, in the opinion of Professor of Electrical Engineering at the Polytechnic University of Valencia, Jose Sanchez-Dehesa.

In its conclusions, the researchers argued that the system called PoWiFi (acronym for “Power over Wi-Fi”) can transform the environment of a router in a wireless access point load.
