Dry Electrode Materials Analysis
Conductive polymers, Ag/AgCl pins, and gold-plated arrays.
Introduction to Electrode Materials
The interface between the amplifier and the scalp dictates the entire signal quality.
Technical Specifications
Dry polymers are comfortable but struggle with impedance. Gold-plated pins penetrate hair but cause pain during extended use.
Data & Methodology
| Parameter | Clinical Standard | Consumer Average |
|---|---|---|
| Impedance Target | < 5 kΩ | 50 - 100 kΩ |
| Usable Duration | > 4 hours | < 1 hour |
Frequently Asked Questions
Can I use dry electrodes for medical diagnostics?
No. The impedance variability makes them unsuitable for identifying specific clinical biomarkers.
