Google already has a smart display with contactless sleep-sending abilities: the Google Nest Hub. Powered by a tiny, built-in radar—sound familiar?—the Nest Hub can actually sense your breathing as you slumber, and it’ll give you detailed reports about your sleep history and quality. The Nest Hub’s sleep-tracking capabilities are powered by Google’s Soli chip, which also handles presence-sensing duties on both the Nest Hub and its bigger sibling, the 10-inch Nest Hub Max. Contactless sleep sensing via radar makes for an attractive alternative to a wearable fitness tracker, such as those made by Google-owned Fitbit. While you must remember to wear a Fitbit to bed to keep tabs on your sleeping habits, a sleep-sensing display like the Nest Hub can track sleep without the using having to bother with a wearable.
