Experts say artificial intelligence (AI) might change sleep medicine entirely, reports TIME.

In 2017, Katabi and her team tested a way to monitor sleep information without any wires or electrodes. Instead of FDA-approved sleep staging devices, they used a device that emits radio frequency signals that bounce off the body. Because even tiny movements — think muscular twitches or blood pulsing, not rolling over or kicking a leg — alter the way these signals travel, the researchers developed an AI algorithm that would associate the data obtained from the radio waves with certain stages of sleep.
