Characteristics of EEG electrodes 

1. Reflect the excitation or inhibition state of the cerebral cortex, accurately provide detection and evaluation of EEG consciousness state, and meet clinical needs;

2. The brain electrode does not contain latex and uses imported conductive adhesive and high-quality 3M double-sided adhesive, with low impedance and good adhesion;

3. Through biocompatibility testing, there is no cytotoxicity, skin irritation, or sensitization reaction;

4. The product has been clinically validated for 7 years, with sensitive measurement and precise numerical accuracy;

5. Good product compatibility

6. Strong anti-interference ability, the sensor has a certain degree of anti-interference ability against the electromagnetic signals of other electrical equipment.
