The actiCAP active electrode system makes it easier to reduce the impedance of the electrodes. This system also substantially reduces the time taken to prepare test subjects up to the start of the EEG recording.
The sensors consist of high-quality Ag/AgCl (sinter) and are perfectly suited for DC acquisition. "Active" circuits permit recordings at high transition resistances (up to 500 kOhm) and minimize ambient noise, interference due to electrical effects and artifacts due to cable movement thanks to built-in active shielding.
This technology significantly improves the signal to noise ratio even without abrasive impedance minimization and additional cleaning of the skin using alcohol or cleaning products.
The different color LEDs which are integrated in the electrode housing indicate the quality of the current electrode transition resistance. Threshold values (red, yellow, green) and additional functions can be programmed using the supplied actiCAP Control Software and displayed on a computer screen. These EEG types is highly indicated to Event Related Potential (ERP) Experiments.
Examples of actives electrodes:
ActiCAP slim and ActiCAP snap – with the hardware ActiCHamp plus, LiveAmp (all), BrainAmp Standard, BrainAmp DC and V-Amp.
