Traditional brainwave monitoring (EEG) systems require hospital visits, bulky
equipment, and often fail to record accurate data during daily activities.
Wearable EEG devices exist but struggle with signal noise—especially from
motion (like walking or chewing). These motion artifacts often drown out the
brain signals and make diagnosis unreliable, especially for conditions like
epilepsy. Existing systems either amplify everything (including noise) or
filter too much, risking the loss of important brain data.
Solution
This invention introduces a smart wearable EEG system with advanced active electrodes—tiny devices worn on the head that not only detect brain signals but clean and improve them on the spot before sending them to a backend device. Each electrode contains built-in electronics that amplify only the useful brain signals, remove motion-related distortions, and block electrical interference from things like power lines.
Inventive
Step
Unlike older systems that process signals after they’re transmitted (leading to noise problems and high energy use), this invention processes and cleans the signals directly at the electrode. A key innovation is a smart “artifact removal module” that estimates what part of the signal is just movement noise and subtracts it in real time. It also features self-calibrating technology to adapt to changes in the user’s motion or skin contact—ensuring accuracy without manual adjustments.
Tangible Benefits
- Accurate brain monitoring during daily life
- Less need for hospital stays
- Faster, more reliable diagnoses
- Lower power use = longer battery life
- Comfortable and easy to wear
Broader
Impact
This system makes neurological care more accessible and affordable, especially for patients in rural or underserved areas. It supports better remote healthcare, earlier diagnosis, and potentially life-saving interventions—pushing brain monitoring technology toward a more mobile, inclusive future.
