What if the room you sleep in could tell you something is off before you feel it? James Kotecki talks with Sam Yang, CEO and co-founder of Xandar Kardian, about a baseball-sized radar sensor that reads heartbeat and breathing from your nightstand or wall, with no camera, no microphone and nothing to wear. Built for hospitals and nursing homes, Sam says it has flagged changes in people’s vitals days before something went wrong, and it’s now coming to consumers. Hear why he says radar can measure breathing instead of estimating it, how sensing like this could show up in appliances and phones and what’s coming at CES 2027. First in our three-part miniseries, “AI in Action."
