EEG and neurorehabilitation research
I designed and evaluated electrode attachments for Type IV Afro textured hair, working between CAD, resin 3D printing, human subject testing, and neural signal analysis.
Open Hair and Braided Hair attachment geometries.
Contact, impedance, disconnections, alpha SNR, and comfort.
Fewer electrode disconnections and better contact with comparable resting alpha SNR.
Technical highlights
- Modeled and resin printed attachments intended to improve scalp contact while accommodating different hairstyles.
- Worked with 32 channel EEG, IMUs, and instrumented insoles in multimodal gait and mobility studies.
- Measured scalp contact, impedance, signal quality, and participant comfort.
- The study poster reported fewer disconnected electrodes and lower impedance. The difference in comfort ratings did not reach statistical significance.
The repository includes MATLAB and Python analysis scripts, plus 3D-printable electrode STL files. Raw human-subject EEG recordings are not included.
