Abstract

The limitations of current electroencephalographs are unanimous and relate primarily to its low spatial density and assembly complexity for certain applications. In this paper, we introduce an innovative technique, capable to answer to some challenges created by those limitations. A localized, miniaturized and user-friendly electroencephalography (EEG) sensor was developed for signal acquisition in a bipolar montage, to be placed anywhere on the scalp. The low consumption, small size and high spatial resolution, compared with the standard systems, are the main features of the EEG sensor presented. With this sensor we acquired and analyzed spontaneous EEG activity and auditory evoked potentials which are relevant for the cognitive activity analysis. The developed sensor is an important unobtrusive tool for applications of mental health evaluation.
