Strategic Objectives
• Master the mechanical physics of hair-parting electrode geometries.
• Optimize spring-loaded mechanisms for consistent scalp pressure.
• Select biocompatible materials that balance conductivity with durability.
• Design structural pin arrays that maximize signal-to-noise ratios.
The Core Challenge
Traditional EEG requires messy gels and skin preparation, while current dry sensors struggle with hair interference and signal stability without causing physical discomfort.
