Development of polydimethylsiloxane (PDMS) and silver ball based dry type flexible EEG electrode for EEG recording

Abstract

Objectives: Ag/AgCl electrode, which is the most commonly used to measure scalp EEG potential, is usually required conductive gel or paste that convey ion between scalp and electrode. For using this electrode, skin abrasion is required to decrease scalp-electrode impedance. It may become painful, EEG recording based upon discomfort. Furthermore, individual site preparation precludes rapid application of an EEG electrode in emergency settings. It has risk of infection, too. The aims of this study are develop dry-type of EEG electrode which does not requires conductive gel or paste to record scalp EEG potential and tests of performance.
