EEG Headset

A low-cost, comfortable EEG headset for brain-computer interface experiments.

Neurotech Hardware Design Prototyping 3D Printing
EEG Headset

Commercial EEG headsets are expensive and uncomfortable for long sessions. I designed a 3D-printable headset with adjustable electrode mounts and dry electrodes, built around an OpenBCI-compatible board.

What I Did

  1. 01 Designed a printable headset frame that spreads pressure evenly for long sessions.
  2. 02 Placed adjustable electrode mounts around the 10-20 electrode system.
  3. 03 Iterated through printed versions to tune electrode contact pressure.
  4. 04 Integrated an OpenBCI-compatible board with shielded cabling to cut power-line noise.

Technical Highlights

01

Version 1: open headband

The first version was a slim band that placed electrodes along the 10-20 system positions.

Version 2: wraparound visor

The second version wraps further around the head to spread contact pressure more evenly, with spring-loaded dry electrodes that need no gel.
