Apple researching how to use HomePods, Macs, and iPhones to enhance sleep monitoring

Future sleep tracking could be done without any mattress sensors, or wearable devices, as Apple investigates using an iPhone, Mac, or HomePod mini, to provide physiological monitoring.

If you've ever worn an Apple Watch overnight so as to be woken up by its haptic alarm without disturbing anyone else, you know it's very successful. It isn't the most comfortable, though, and it does also mean you have to find time to charge the Watch in the next day.Wearable sleep trackers are similar in how they're accurate, but could be uncomfortable enough to affect the sleep they're trying to check. A newly-revealed patent shows that Apple has been looking at alternatives, and specifically ones that do not require any physical contact with the person sleeping.
