Samsung Electronics unveiled Samsung SleepSense at IFA 2015 in Berlin last week. The personal healthcare device aims to helps people improve the quality of their sleep.
Sleep is essential for general wellbeing, but with busy and stressful lives, many struggle to achieve the recommended seven to nine hours sleep a night, putting health at risk.
With the Korean company’s SleepSense, users can quickly and easily understand their sleep pattern and learn how to improve it without having to seek advice. It can be a personal sleep consultant.
The sleep-monitoring device uses patented technology to analyse sleep quantity and quality, providing personalised sleep reports and giving expert recommendations on how to improve sleep, all through a mobile app.
The user places the sensor under the mattress, downloads the app on a mobile, connects the two, drifts off to sleep, andthe device gets to work.
Thesleep-tracking sensor has up to 97 per cent accuracy and is available on the consumer market. With a real-time contactless sensor, it analyses heart and respiratory rates, plus movement while asleep, so every morning the user receives a personalised sleep briefing – a summary of sleep activity with sleep score mapped against the average data for the person’s age.
The sleep score is calculated based on seven elements; total sleep time, sleep efficiency, the time it took to fall asleep, the number of times the user woke up, the number of times they got out of bed, percentage of time in REM (rapid eye movement), and percentage of time in deep sleep.
Based on individual sleep score, the app will also provide expert recommendations on how to improve it.
Harvard Medical School professor Christos Mantzoros worked with Samsung to provide personalised professional tips on improving sleep quality, covering lifestyle, nutrition and exercise. Depending on sleep pattern, the user will receive handy tips and words of advice to help sleep better next time.
A comfortable sleep environment is crucial for good quality sleep. To do this, it can be connected to Samsung smart appliances, allowing the user to control air conditioning units and to turn off the television when falling asleep – all designed to provide an optimal sleeping environment. The sensor can also be connected to the Samsung SmartThings app that controls many other devices in the home such as thermostats, security cameras and light bulbs, all of which may affect or assist sleeping conditions.
Being woken up by an alarm ringing while still in deep sleep leaves many people dazed and irritable for the rest of the day. The Smart Alarm feature wakes the user up gradually by analysing the data collated from sleep stages and identifying the best time to wake up, helping the user feel less groggy and sleepy throughout the day, and fresh and energised for the day ahead.
For people concerned that their loved ones – for example elderly family members – suffer from a lack of sleep, SleepSense can help: simply put the sensor under their mattress and select the app’s family care option to receive an analysis of the quality of their sleep via email.
