Technologies Explained
- Dry EEG Sensors: Capture brain signals without conductive gel, making the headset easier to use outside laboratory settings.
- Active Shielding: Reduces external electrical noise by shielding electrode leads, improving signal integrity.
- DRL (Driven Right Leg) System: A feedback circuit that suppresses common-mode interference, particularly 50/60 Hz mains noise, resulting in cleaner EEG recordings.
Overall, the Diadem EEG combines 12-channel dry-electrode acquisition, active shielding, and an optimized DRL system to deliver reliable, high-quality EEG signals suitable for both research and advanced BCI applications.
