I have a couple of devices at home with this technology like my electric tooth brush.
Wireless energy transfer or wireless power transmission is the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load without interconnecting wires. Wireless transmission is useful in cases where instantaneous or continuous energy transfer is needed but interconnecting wires are inconvenient, hazardous, or impossible.
Wireless energy transfer is different from wireless transmission of information, such as radio, where the signal-to-noise ratio (SNR) or the percentage of power received becomes critical only if it is too low to recover the signal successfully. With wireless energy transfer, efficiency is the more important parameter.
Yes, we still require batteries but at least we don't have to find the right power supply and attach the cables any more.
