Afridi featured in WSJ video on air charging
In this Wall Street Journal Video segment, Khurram Khan Afridi, associate professor in electrical and computer engineering discusses the risks of using infrared transmitters under FCC and FDA safety guidelines. "The general limit these days is about one watt of power, so it's very small. A standard light bulb is 60 watts, so even smaller than that," said Afridi.
Companies offering air charging use one of three ways to remotely charge devices; radio waves, microwaves, or infrared light. Infrared light delivers significant power at a distance and while it is a slower charging process than traditional power cord use, continuous slow charging gives batteries a longer lifespan.
