The market of dedicated non-wearable sleep tracker devices have brought us many exciting products that may analyze our sleeping habits, but ResMed has adopted a bit different approach that aims to provide accurate tracking without compromising your bed experience with sensor packages that need to be placed near your head or below your sheets. Their S+ monitoring system comes in a unique non-contact package that fully relies on low-energy radio-waves to achieve monitoring of your bedroom environment and quality of your sleep.
With S+, you get the fully standalone and non-contact sleep tracker package that relies on wireless scanning to achieve precise monitoring and analyzing of vital signs to improve your sleep. It achieves that by using ultra low-power radio waves to detect movement of your upper body (breathing patterns and body movements) during sleep. To achieve this, sleep trackers rely on wristbands or sensors placed on the bed itself. S+ is unique among many of them, enabling true wireless monitoring without anything touching you or being close to you.
This ultra low power radio approach is achieved using Resmed’s patent-protected SleepSensor technology. This technology allows S+ to send a burst of short radio pulses, and reflections of those pulses are captured by the S+ base station like those used by echo location systems used by bats. Differences between radio reflection patterns during your regular night's sleep gives S+ enough data to capture your nighttime breathing patterns, movement in bed, positional changes, twitches and more.
All collected data is gathered into a database that is processed by advanced software algorithms developed by ResMed, enabling S+ to create a record of your breathing, movement, and finally, calculate your overall sleep state score and many other analytics reports that user can access via ResMed’s official mobile app. This includes time spent sleeping, a breakdown of sleep phases (deep, light and REM phases), movement tracker and more.
In addition to being focused on you while you are asleep, S+ also actively monitors your bedroom environment by measuring levels of ambient light, noise, and temperature. All those data points are included in the compiled analytics scores. S+ provides users with personalized and actionable feedback, with suggestions how to improve the quality of your sleep.
S+ comes in the form of a stylish base station that is intended to be placed on your bed stand at the distance of no more than four feet away from your body.
The sensor package is located in a cube that is held in the air by stylish leg stands. The entire box has to be powered by the wall plug, but to make it more convenient, ResMed has included a USB socket that you can use to charge your phone during the night.
Software suite of ResMed S+ is accessible via an official Android and iOS app that features the following services:
