Seems like the guys from Stanford University were also developing small devices, the size of an ant, that are capable of radio communication without having a battery. The idea is similar to what the guys from Washington did. But the implementation seems different. Much of the infrastructure needed to enable us to control sensors and […]

You may already heard that there is a way to harvest energy from radio signals which are abundant in our modern world(TV signal, radio, mobile phone cells, etc). But that harvested energy is not enough to emit WiFI signals. The engineers from the University of Washington  have figured out a way to communicate by reflecting those signals, thus […]
