Assessment of Consciousness States with NextSense Ear Bud Devices

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. The custom mold is created employing a 3D printer following capture of the geometry unique to each patients' ears 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 capture of signals reflecting 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 consisten 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.
