Abstract

New areas of application for electroencephalography are in brain-computer interfaces, where disabled people might be able to interact with their environment based on measured brain signals. However, conventional electroencephalography is not suitable here. Thus, our aim is to develop novel dry electrodes for home use. We developed various novel EEG electrodes with titanium and polyurethane as base materials and nanometer sized coatings of titanium-nitride. We present results of the comparison of these electrodes with gold and silver/silver-chloride electrodes. In conclusion, our novel electrodes show equivalent signal quality compared to conventional electrodes and are suitable for home use.
