EEG is critical for diagnosing and assessing neurological conditions like epilepsy and brain injuries. In some cases, clinicians need to monitor brain waves for longer periods of time, for example, to evaluate seizures, sleep disorders and conditions that affect the blood vessels and blood flow in the brain.

The researchers described the new electrodes, which were shown to maintain stable performance for over 24 hours of continuous wear, in a study published in the journal npj Biomedical Innovations. This technology holds promise for use in consumer health and wellness products, in addition to clinical health care applications, according to the researchers.

“This electrode allows for more consistent and reliable monitoring of EEG signals and can be worn without being noticeable, which enhances both functionality and patient comfort,” said Tao Zhou, Wormley Family Early Career Professor of engineering science and mechanics and senior author on the paper.
