Sleep trackers: These devices estimate sleep by measuring inactivity and tracking sleep duration, quality, and phases
Sleep trackers are devices that estimate sleep patterns by measuring inactivity and tracking sleep duration, quality, and phases. They are popular among people who want to measure and optimise their sleep and overall health. Sleep trackers come in various forms, including wearable wrist trackers, rings, headbands, mats, and clips that attach to your pillow or sit on your bedside table. These devices can be helpful for those who want to gain insight into their sleep routines and recognise patterns in their sleep habits.
While sleep trackers do not directly measure sleep, they estimate sleep by tracking periods of inactivity. They record the time you are inactive to determine when you fall asleep and when you wake up. This allows them to calculate the duration of your sleep. Additionally, sleep trackers can detect interrupted sleep by sensing movement during the night, such as tossing and turning.
One of the key features of sleep trackers is their ability to track sleep phases. These devices can monitor the different stages of sleep, such as REM sleep or deep sleep, and provide insights into the quality of your sleep. Some advanced trackers can even time your alarm to go off during a period of lighter sleep, making it easier for you to wake up.
Sleep trackers also offer various additional features. Some trackers prompt you to enter information about lifestyle factors that can impact your sleep, such as caffeine intake, stress levels, and eating habits. Environmental factors like light and temperature in your bedroom may also be recorded by certain devices. More comprehensive trackers can measure heart rate, heart rate variability, blood oxygen levels, respiratory rate, body temperature, and even metrics related to women's health, such as menstrual cycles.
It is important to note that sleep trackers may not always provide medically accurate data. For precise sleep data, a medical sleep study or polysomnography test is recommended. Sleep trackers are useful for gaining general insights and recognising patterns, but they should not replace the advice of a health practitioner for serious sleep concerns.

Polysomnography: A medical sleep study that monitors brain waves and other sensors to diagnose sleep disorders
Polysomnography is a medical sleep study that uses various sensors to monitor an individual's sleep patterns and diagnose sleep disorders. It is often recommended when individuals exhibit symptoms of conditions that affect sleep, such as sleep apnea, narcolepsy, periodic limb movement disorder, or sleep behaviour-related issues like sleepwalking. Polysomnography provides an in-depth analysis of sleep by tracking multiple body systems and processes.
Polysomnography involves sensors that monitor brain wave activity, eye movement, and the heart's electrical activity. These sensors provide valuable insights into the different stages of sleep and help identify any disruptions or abnormalities. The study also includes video and audio monitoring, allowing sleep lab staff to observe and hear what happens during sleep, which can be crucial for interpreting sensor data and understanding unusual readings.
Additionally, polysomnography may employ sensors that detect breathing patterns, including breathing-related muscle movements in the chest and abdomen. This is particularly relevant in cases of suspected sleep apnea. Other sensors may measure ambient temperature, humidity, and noise, as these environmental factors can also influence sleep quality. Some devices even use microphones to measure ambient noise and assess sleep-related behaviours like snoring.
Polysomnography is considered the gold standard for obtaining medically accurate sleep data. While sleep trackers and wearables have become popular, they often rely on actigraphy, which measures movement, and may not always provide precise information. Polysomnography, on the other hand, offers a comprehensive evaluation of sleep by analysing multiple physiological parameters.
Polysomnography is typically conducted in a sleep lab, and individuals undergoing the study are advised to maintain their usual routine beforehand. They may also be guided on medication adjustments and instructed to avoid caffeine and alcohol for at least eight hours before the study. The procedure usually takes place during an individual's normal sleeping hours, ensuring a natural sleep environment for accurate results.

Electrochemical sensors: Able to detect metabolites, electrolytes, and hormones from bodily fluids like sweat and tears
Sleep trackers and activity trackers are commonly used to monitor sleep patterns and sleep quality. These devices can be worn on the wrist, clipped to a pillow, or placed on a bedside table. They can track sleep duration, quality, and phases by measuring periods of inactivity. However, these devices do not directly measure sleep and instead rely on inactivity as a surrogate for estimating sleep.
For precise data on sleep habits, medical sleep studies are conducted, which monitor brain waves to analyze the various stages of sleep. These studies are particularly useful for diagnosing sleep disorders such as sleep apnea.
In recent years, advancements in electrochemical sensors have expanded their capabilities to detect metabolites, electrolytes, and hormones from bodily fluids like sweat, tears, saliva, and skin interstitial fluid. These sensors leverage nanomaterials, such as carbon nanomaterials, precious metals, and polymers, to enhance their performance. Common detection methods include cyclic voltammetry (CV), differential pulse voltammetry (DPV), square wave voltammetry (SWV), and electrochemical impedance spectrum (EIS).
Wearable electrochemical sensors have been developed to monitor metabolites and electrolytes in human biofluids. These sensors can non-invasively measure biomarkers such as glucose, lactate, potassium, and sodium in sweat. They offer a convenient alternative to blood analyses, providing continuous monitoring of physiological biomarkers critical to human health. However, current wearable sensors often require vigorous exercise to access sweat, limiting their daily usability.
Recent innovations have addressed these limitations by integrating laser-engraved graphene (LEG) with electrochemically synthesized redox-active nanoreporters (RARs) and molecularly imprinted polymer (MIP)-based 'artificial antibodies'. This combination enables the sensitive and selective detection of a wide range of biomarkers, including essential amino acids, vitamins, metabolites, lipids, hormones, and drugs. The flexible and disposable sensor patches can be comfortably attached to the skin and wirelessly communicate with a custom mobile app for dynamic metabolic information processing and storage.
These advancements in electrochemical sensors hold great potential for non-invasive, continuous monitoring of physiological biomarkers, contributing to our understanding of sleep psychology and overall human health.
