Passive Wi-Fi more energy efficient than conventional Wi-Fi, ZigBee and Bluetooth LE

While it's become a necessity of modern life, Wi-Fi is also an energy hog, draining the batteries of all those connected devices surrounding us. That may change with the recent demonstration by University of Washington researchers of Wi-Fi transmissions generated using 10,000 times less power than conventional methods. Known as Passive Wi-Fi, the system also uses 1,000 times less power than current energy-efficient wireless communication platforms, like ZigBee and Bluetooth LE.Read More

Tiny temperature sensor powered wirelessly with radio waves

One of the problems for the smart buildings of tomorrow is that they may depend on some very un-smart wires to power them. To cut the cord, Eindhoven University of Technology (TU/e) researcher Hao Gao, as part of his PhD thesis, is developing a tiny transmitting temperature sensor that is powered by radio waves to eliminate the need for wires or batteries. Instead, it picks up radio waves from a special router, converts them into electricity, and uses it to transmit readings.Read More
