Samsung has revealed SleepSense, a smart personal healthcare device that enables the user track their sleeping and understand how to improve it.

Placed underneath the users mattress, the SleepSense monitors heart and respiratory rates through a contactless sensor, as well as any movement during sleep, with up to 97 per cent accuracy, according to Samsung.

This info is sent to a paired mobile app, which provides the user with a personalised sleep briefing summarising their sleep activity. This includes a sleep score, based on total sleep time, sleep efficiency, how long it took to fall asleep, the number of times the person woke up or got out of bed, and proportion of time spent in REM and deep sleep.

The SleepSense can also be connected to Samsungs smart home devices, to automatically control the temperature or switch off the television when the user is falling asleep, or to its SmartThings app to control a number of other devices, like smart lightbulbs.
