Soon our houses will become "wiser". And for this to happen, they must be filled with a variety of devices that will make life easier for us. Motion, temperature, air pollution sensors, various photo and video cameras and much more. Such houses will need energy. But lead to them wires or constantly change batteries expensive. Several groups of researchers are working to ensure that various gadgets can receive energy, as they say, from the air.
The space surrounding us is filled with radio waves, for example radio signals of the Wi-Fi band. Scientists from the University of Washington took a standard Wi-Fi router, made small changes to it, and now it can be used as an energy source for remote devices. At the same time, it can still perform its basic function, the quality of the connection has not affected the conversion.<s/trong> In my opinion this would not be bad :)
As the energy consumption of various devices decreases, when they need a minimum amount of electricity to perform their tasks, the popularity of wireless power transmission will grow.
