Mattress-based actigraphy or bed/room sensors

Mattress-based actigraphy works by tracking body movement using the accelerometer in your phone. To use this method, simply place your phone on your mattress when you go to sleep. Some mattress-based trackers, like the Withings Sleep Analyzer, also track breathing and heart rate and can detect snoring or other sounds. The data is then processed to produce reports on your sleep cycle, heart rate, and breathing, along with an overall sleep score.

Smart mattresses are another option for sleep tracking. These technologically advanced mattresses have sensors built into the cover that can track your sleep. This can be a good choice if you are in the market for a new mattress and are not interested in daytime activity tracking. The Eight Sleep Pod 4 Cover and Hub is an example of a smart mattress cover that can track temperature (ambient and body), heart rate, heart rate variability, respiratory rate, movement, and sleep stages.

In addition to mattress-based trackers, there are also bed and room sensors that can be placed on your bedside table or another nearby surface. The Google Nest Hub is an example of a bed/room sensor that can be used to track your sleep without a wearable device.

Acoustic sleep monitoring via a phone's microphone

Sleep is an essential part of our lives, and tracking it can provide valuable insights into our health and daily routines. While many people use smartwatches and fitness bands to monitor their sleep, it is also possible to track sleep without a watch. This can be done through your smartphone, which has various apps and features that enable sleep tracking. One method of sleep tracking that utilizes your smartphone is acoustic sleep monitoring via your phone's microphone.

Acoustic sleep monitoring involves using your phone's microphone to track sound patterns and body movements during sleep. The microphone picks up sounds such as breathing, snoring, sleep talking, and physical movement, which are then analyzed to determine your sleep patterns and quality. This method of sleep tracking is non-contact and can be done by placing your phone on a bedside table or near your bed.

One example of an app that uses acoustic sleep monitoring is Sleep Cycle. This app can track your sleep stages and provide insights into your sleep duration and quality. It utilizes the phone's microphone to detect and analyze sound patterns, contributing to its sleep-tracking capabilities.

Sonar technology to track movement and breathing rate

Sonar technology has emerged as a promising method for tracking movement and breathing rates during sleep, offering a contactless approach to sleep monitoring. This technology utilizes inaudible or near-inaudible sound waves to accurately capture sleep data without requiring physical contact with the user.

Sonar-based sleep tracking systems typically employ a smartphone placed on a bedside table, equipped with a custom app that uses advanced algorithms. These algorithms are designed to identify different sleep stages, including Wake (W), Light Sleep (N1 and N2), Deep Sleep (N3), and Rapid Eye Movement (REM) sleep. The sonar system emits sound waves that safely fall within the range of human hearing, with volumes comparable to a normal conversation or a pin dropping.

One notable advantage of sonar technology is its ability to measure breathing rates accurately. By emitting sound waves and analyzing their reflections, sonar can detect subtle changes in a person's breathing patterns during sleep. This capability is particularly useful for identifying breathing disorders such as sleep apnea, as it provides valuable insights into respiratory health during sleep.

In addition to breathing rate, sonar technology can also track body movement during sleep. This movement tracking helps differentiate between various sleep stages and can provide information about restlessness or periods of stillness. By combining movement data with breathing rate analysis, sonar-based systems offer a comprehensive understanding of sleep patterns and quality.

Sonar sleep tracking has been the subject of several studies, with promising results. For example, a study by Zaffaroni et al. (2019) utilized sonar smartphone technology to detect sleep apnea and identify sleep-disturbed breathing patterns. Another study by Lyon et al. (2019) employed sonar to monitor movements and respiration, demonstrating its potential for sleep apnea detection and sleep stage monitoring. These studies highlight the growing body of research supporting the effectiveness of sonar technology in sleep tracking and its potential to enhance our understanding of sleep health.
