Wearable Sleep EEG and Auditory Stimulation in Healthy Adults

1. September 2026 aktualisiert von: Ali Yousefi, University of Houston

Evaluation of a Wearable Sleep Monitoring Platform With Acoustic Stimulation for Mood Regulation

The purpose of this single-site pilot study is to evaluate the feasibility, usability, and technical performance of a wearable sleep-monitoring system that records electroencephalography (EEG) and delivers brief, low-volume sounds during selected stages of sleep.

Approximately 30 healthy adults aged 18 to 30 years will use the system at home for up to 12 weeks, with a target of at least 15 usable nights of sleep recording. Participants will also complete smartphone-based assessments of sleep, mood, stress, device experience, and memory.

The study will evaluate home-use completion, EEG signal quality, automated sleep-stage detection, delivery of auditory stimulation, participant adherence, and safety and tolerability. This pilot study is intended to refine the device and study procedures and is not designed to determine whether the system treats depression or another medical condition.

Detaillierte Beschreibung

Participants will complete eligibility screening and provide written informed consent before beginning study procedures. At enrollment, University of Houston study personnel will provide training on placement and removal of the forehead sensor, use of the study smartphone and application, device handling and charging, reporting of discomfort or technical problems, and procedures for stopping device use.

Participants will use the wearable EEG-based sleep-monitoring system at home during natural sleep for up to 12 weeks, with a target of at least 15 usable nights of sleep data. The external, battery-powered, non-invasive system records EEG and device-session information, supports automated sleep-stage detection, and delivers brief, low-volume pink-noise sounds during selected stages of non-rapid eye movement sleep according to study-configured closed-loop timing parameters. The device does not deliver electrical stimulation to the participant. Device and auditory-stimulation settings will be configured by study personnel and will not be adjusted by participants.

During the home-use period, participants will complete smartphone-based assessments that include sleep-diary information, sleep quality, mood, stress, device feedback, and memory tasks. Study personnel will provide technical assistance and monitor device use, data quality, participant-reported discomfort, and device or application problems.

Study analyses will focus on home-use feasibility, completion of usable recording nights, participant adherence, EEG signal quality, automated sleep-stage classification, slow-wave activity, delta sleep ratio, auditory-stimulation timing and delivery performance, application completion, and safety and tolerability. Findings will be used to refine the wearable system, signal-processing algorithms, participant instructions, and study procedures before a later clinical assessment in adults with major depressive disorder.

Experimental: Wearable EEG Monitoring and Closed-Loop Auditory Stimulation
Participants will use the investigational wearable EEG-based sleep-monitoring system at home during sleep for up to 12 weeks, targeting at least 15 usable nights of recording. The system records sleep EEG and device-session information and delivers brief, low-volume auditory stimulation according to study-configured closed-loop timing parameters. Participants will also complete smartphone-based sleep, mood, stress, device-feedback, and memory assessments.

Maßnahmenbeschreibung
Zeitfenster
Proportion of Participants Completing at Least 15 Usable Home Sleep-Recording Nights
Zeitfenster: From initiation of home use through the end of the home-use period, up to 12 weeks
Number of participants completing at least 15 usable nights divided by the number of enrolled participants who initiate home use. A usable night contains sufficient continuous wearable EEG and device-log data for the planned signal-processing and algorithmic stimulation-delivery analyses. The prespecified feasibility benchmark is greater than 75%.
From initiation of home use through the end of the home-use period, up to 12 weeks
