Quantification of the electrochemical characteristics of g-MEA with 400-μm diameter electrodes (n = 16) at each fabrication step. (A) IS (magnitude and phase) and CV performed at each fabrication step. Colored lines represent average values and gray lines the ± SD. (B) Impedance magnitude at 1 kHz (p < 0.0001, Kruskal–Wallis test with Dunn’s multiple comparisons test). (C) Impedance phase at 1 kHz (p < 0.0001, one-way ANOVA with Tukey’s multiple comparisons test). (D) Anodic CSC (p < 0.0001, Kruskal–Wallis test with Dunn’s multiple comparisons test). (E) Cathodic CSC (p < 0.0001, Kruskal–Wallis test with Dunn’s multiple comparisons test). In all panels P:PSS means PEDOT:PSS.
