Check out the videos below showing the feature rich technology and see how S+ by ResMed can introduce you to better sleep.

  • Our “Mind Clear” feature offers simple text and voice tools for recording tomorrow’s to-do list so you can go to sleep with a calm, uncluttered mind.
  • Specially designed sounds synchronise with your breathing, gradually slowing it down to help you fall asleep more easily.
  • Monitors the four stages of your sleep (sleep onset, light sleep, deep sleep and REM) and whenever your sleep is interrupted
  • Creates a personalised sleep chart comparing your sleep against an ideal night’s sleep for your age and gender
  • Instead of waking you up at a set time, Smart Alarm aims to gently wake you from light sleep close to when you need to be up, helping you feel more refreshed. Choose a time window that suits you and S+ by ResMed Smart Alarm will do just that. (If you don’t reach light sleep within the time window, Smart Alarm will wake you at your desired time.)
  • Analyses your sleep results against averages for your age and gender, and then provides a daily sleep score along with a breakdown of how you slept
  • Provides personalised daily feedback you can use to sleep better that night
  • Measures your breathing and physical movements

The technology behind S+ by ResMed

Technology Found in Nature

S+ by ResMed measures movements using ultra low power radio waves (less than 1/10 of Bluetooth®). The basic principle is similar to the echo location system used by bats to hunt insects.

S+ by ResMed transmits a short pulse of radio waves at 10.5 GHz and then listens for the echo of the pulse. As you move, the phase of the echo changes and is converted into a signal that reflects your movement.

Clothing and blankets are almost transparent to radio waves at the frequencies we use. The echo signal is mostly generated by reflection from your body – as far as radio waves are concerned, you’re a large watery object!

Contactless Technology

A major component of S+ by ResMed system is our patent-protected Sleep Sensor that lets it monitor your sleep without actually touching you. No mattress strips. No wristbands. Just a nightstand monitor that can accurately record your breathing and movement.

Proprietary software performs a variety of signal analysis tasks including respiration analysis and sleep quality measurement.

S+ by ResMed technology’s ability to accurately measure sleep patterns has been published in 10 scientific papers, and has been tested and proven against expert manually scored patient sleep data gathered in several accredited sleep laboratories.
