actiCAP

Overview

actiCAP* - The third generation of active electrodes

actiCAP is a ground-breaking development aimed at raising EEG and ERP research to the next level. It combines active electrodes based on high-quality Ag/AgCl sensors with impendance conversion at electrode level leading to much lower noise levels compared to conventional passive electrodes.

In June 2017 we launched a new and further improved version of our actiCAP system: actiCAP slim and actiCAP snap.
Low weight, low profile, electrode arrangement flexibility, plus all the benefits of the original actiCAP technology ... more details.
