Dry-Contact Electrode Ear-EEG

Activity: Talk or presentation typesLecture and oral contribution

Description

Ear-EEG is a recording method where EEG signals are acquired from electrodes placed on an earpiece inserted into the ear. Previously reported ear-EEG recordings have been performed with wet electrodes, and the objective of this study was to develop and evaluate dry-contact electrode ear-EEG. A novel dry-contact ear-EEG platform, comprising electrodes embedded in a soft-earpiece, was developed. The platform was evaluated in a study of four EEG paradigms: auditory steady-state response, steady-state visual evoked potential, mismatch negativity, and alpha band modulation. With both the measuring electrode and the reference electrode located within the ear, statistically significant (p$<$0.05) responses were measured for all paradigms, although for mismatch negativity it was necessary to use a reference located in the opposite ear, to obtain a statistically significant response. The prototyped dry-contact ear-EEG platform represents an important technological advancement of the method in terms of user-friendliness and suitability for long-term use.
