Fig. 3: Comparison of recording performances between TTEs and Ag/AgCl electrodes.
From: Conducting polymer tattoo electrodes in clinical electro- and magneto-encephalography
a, b Time-frequency plot of alpha wave recordings, with visible 10 Hz activity obtained with tattoo (a) and AgAgCl (b) electrodes. c Superimposed PSD (dB) during alpha wave recordings from TTEs—in red, and Ag/AgCl electrodes—in blue. The insert at the bottom left shows the electrodes placement with used derivation (Tz–Cz, in light blue for the TTE, and sT7-sCz for the Ag/AgCl electrodes in light violet). d Picture of two electrodes in Cz position on the head of the participant. e Auditory Evoked Potential recorded with both TTEs (red) and Ag/AgCl electrodes (blue), with N100- an auditory evoked potential component.
