    “RF wireless charging is a type of uncoupled wireless charging in which an antenna embedded in an electronic device can pick up low level radio frequency waves from external sources and convert the waves’ energy to direct current (DC) voltage.”

    I can’t find that quote in the article—or anything that definitively indicates they’re talking about RF power rather than RFID signals (other than saying the transmitters “power up” all the switches, which could just be sloppy terminology.)

      Sorry. Yeah, that’s not a quote from the article. Just just something I went and grabbed elsewhere real quick to explain rf power.
