Current obstacles

User comfort and signal stabilityDry EEG electrodes must maintain good contact; discomfort and motion artifacts limit session duration.

Physics limits

Limited spatial resolutionConsumer EEG headbands have few channels; they cannot pinpoint brain activity location with the precision of research-grade systems.

How it works

3 parts

EEG sensing

Scalp electrode detection

Dry or wet electrodes detect electrical brain activity across different frequency bands (delta, theta, alpha, beta, gamma).

Real-time analysis

Brain state interpretation

Firmware interprets brain patterns to classify attention, relaxation, sleep stage, and other cognitive states.

User feedback

App-based training

Mobile app provides real-time feedback and gamified training exercises to help users improve focus or relax.
