[BENCHMARK WITH THE PSG](https://iduntechnologies.com/science?hsLang=en) Longitudinal measurements ## Outside of the sleep lab The IDUN Guardian can be used for longitudinal measurements of high-quality sleep EEG and movement, enabling researchers to explore sleep and its effect on mental health at scale and over longer periods of time. ![sleep and app](https://iduntechnologies.com/hs-fs/hubfs/sleep%20and%20app.jpg?width=2000&height=1333&name=sleep%20and%20app.jpg "sleep and app") SLEEP EEG ## **Bridging the Gap** Smartwatches are [widely used to measure sleep](https://www.hopkinsmedicine.org/health/wellness-and-prevention/do-sleep-trackers-really-work), but they are often inaccurate since they only estimate brain activity. [Polysomnography (PSG)](https://pubmed.ncbi.nlm.nih.gov/31277862/#:~:text=PSG%20is%20considered%20to%20be,sleep%2Drelated%20hypoventilation%2Fhypoxia.) is the gold standard for sleep measurement but it is restricted to a lab, requires a trained technician and is expensive and cumbersome. The IDUN Guardian strikes a balance between both, combining the wearability of smartwatch with the accuracy of the PSG in capturing sleep EEG. SLEEP MARKERS ## **Validated for Reliability and Accuracy** EEG analysis is a powerful tool for understanding various aspects of sleep, from its onset to different stages. It identifies specific brain wave types, such as alpha, beta, delta, and theta, which correlate with different sleep stages. Beyond just classifying sleep stages, EEG can assess sleep quality and has the potential to detect disorders like insomnia and narcolepsy. Sleep markers shown by in-ear EEG data: - Shift from high-frequency activity to low-frequency activity (Wake – N1) - Eye movements (Wake – N1 and possibly also for REM classification) - Sleep Spindles (N2) - K-Complexes (N2) - Slow-wave sleep (N3) - Breathing patterns ![photo_5805259010989998227_x](https://iduntechnologies.com/hs-fs/hubfs/photo_5805259010989998227_x.jpg?width=478&height=532&name=photo_5805259010989998227_x.jpg "photo_5805259010989998227_x") SLEEP MICROARCHITECTURE ## Outside of the sleep lab Beyond the confines of sleep labs, In-Ear EEG offers a nuanced view of sleep microarchitecture, capturing key indicators like K-complexes and sleep spindles. This technology provides a more comprehensive analysis compared to actigraphy and smartwatches, which focus primarily on sleep macroarchitecture. ![Sleep markers](https://iduntechnologies.com/hs-fs/hubfs/Sleep%20markers.png?width=2000&height=979&name=Sleep%20markers.png "Sleep markers") ## Advantages of the IDUN Guardian over the PSG #### Convenient Can be used in the comfort of home. #### Comfortable Ergonomic design to provide comfort to the user during sleep. #### Easy-to-use Easy for the user to set up without needing a trained technician. #### Long-term sleep monitoring Can be used regularly for longitudinal sleep recordings.
