Integration of low-cost, dry-comb EEG-electrodes with a standard electrode cap for multimodal signal acquisition during human experiments

Abstract

This paper describes development of an experimental setup that enables convenient and fast integration of low-cost, spring-loaded, dry electroencephalography (EEG) electrodes with a research-grade sensor cap. The proposed setup increases available electrode positions compared to the current equipment, and constitutes a pragmatic, low-cost approach for integrating EEG-measurements in combination with other brain activity sensors. The proposed solution aims to lower the barrier for including EEG as an additional modality in existing experimental setups.
