SCIENTIST have created the world's first technology that can connect battery free devices to Wi-Fi.'Wi-Fi back scatter ' technology as it is known.This technology can connect battery free devices to Wi-Fi infrastructure.This technology will help our wristwatch or similar device to directly communicate with our online profiles.
University of Washington 's engineers have designed a new communication system that uses radio frequency signals as a power source and reuses existing Wi-Fi infrastructure to provide internet connectivity to these devices.
Sensors could now be embedded in every day objects to help monitor and track everything from the structural safety of a bridges to the health of your heart. But having a way to cheaply power and connect these to the internet has kept them from taking off.
This work builds up upon previous research that showed how low powered devices such as temperature sensors or wearable technology could run without batteries or cord by harnessing energy from existing radio, TV and wireless signals in the air.This work takes that a step further by connecting each device to the internet which previously was not possible.
According to Sh yam Gollakota, a University of Washington assistant professor of computer science and engineering ,now there is the ability to enable Wi-Fi connectivity for devices ,while consuming order of magnitude less power than what Wi-Fi typically requires.
The challenge in providing Wi-Fi connectivity to these devices is that conventional,low power Wi-Fi consumes three to four order of magnitude more power than can be harvested in these wireless signals.
FASTEST EXTERNAL PHONE CHARGER.
Researchers have invented the world's fastest external phone charger which ends the need to plug your smartphone into an electricity socket and can charge your device in fifteen minutes.This is the new Peta lite Flux battery - it is small enough to fit in a pocket and has been created by Leigh Purnell, An Aston University graduate.It will be launched on the Indiegogo crowd funding website .
