Comparison of foam-based and spring-loaded dry EEG electrodes with wet electrodes in resting and moving conditions

Abstract: The introduction of dry electrodes for EEG measurements has opened up possibilities of recording EEG outside of standard clinical environments by reducing required preparation and maintenance. However, the signal quality of dry electrodes in comparison with wet electrodes has not yet been evaluated under activities of daily life (ADL) or high motion tasks. In this study, we compared the performances of foam-based and spring-loaded dry electrodes with wet electrodes under three different task conditions: restin… Show more

“…There are other means to compare EEG systems, for example, the correlation of waveforms from two different EEG systems during a simultaneous recording from electrodes located near each other (Gargiulo et al, 2010; Yeung et al, 2015). Many mobile EEG systems have a rigid montage, and it is not possible to overlay montages of two different EEG systems.…”

“…The developed benchmark of six paradigms and yielded results can be used for evaluation of new EEG systems. In contrast to other studies (Gargiulo et al, 2010; Guger et al, 2012; Liao et al, 2012; De Vos et al, 2014; Yeung et al, 2015; Oliveira et al, 2016b), which compare EEG signals from different systems, we match the difference between EEG systems to other factors of variance, like subjects and sessions, in order to estimate the importance of the difference between EEG systems. We also demonstrated the mesh-head-model interpolation approach, which addresses the issue of not overlapping EEG montages of different EEG systems.…”

“…Since then, a wide number of materials have been considered for making dry EEG electrodes [19,20,21,22]. The commercially available g.SAHARA electrodes [9,23] use gold and a similar closely-positioned impedance-converting amplifier approach.…”

“…Another recent study from Wang et al compared power spectra and time-frequency maps (spectrograms) between the two systems to evaluate the feasibility of novel semi-dry electrodes (Wang et al, 2016 ). Although these novel system designs show promise in a controlled laboratory setting, few studies have shown the feasibility of individuals using these systems in a dynamic, real-world environment (Gargiulo et al, 2008 ; Liao et al, 2012 ; Lin et al, 2013 ; Yeung et al, 2015 ).…”
