Sleep/Wake State Assessment with Non-invasive Earbuds

Each NextSense EEGBud device comes with a universal-fit and/or custom-fit earmold with biometric sensors to detect the EEG, motion (via tri-axial accelerometers), and heart rate. A unique custom mold is created employing a 3D printer to capture the geometry of a patients' ear and external auditory canal with a ring laser scanner to an accuracy of within 0.1 mm. This design process allows for a custom fit, and therefore both comfort and complete, consistent contact with the inner surface of the ear canal, providing high quality signal capture of brain activity, and head and eye movements. In addition to the custom fit earmold, universal fit earmolds are available as well. The universal fit earmolds were designed also to allow for comfort and consistent contact with the inner surface of the ear canal to provide high quality signal capture of brain activity, and head and eye movements.

Ellcie Healthy glasses frames are embedded with multi-modal sensors for measuring eye movements, head movement, and ECG.

Participants will not take their prescribed wakefulness promoting medication(s) for one day to complete the study assessments. Medications typically used to promote wakefulness include amphetamine salts (Adderall), armodafinil (Nuvigil), clarithromycin (Biaxin), flumazenil, methylphenidate (Ritalin), and modafinil (Provigil).
