Characterization of the OECTs for ion concentrations measurements. Real-time normalized response to varying concentrations of ions, Na+ (left), K+ (middle), Ca3+ (right) with the injections of the different ion concentrations (DI water, 1, 10, 100, 10, 1 mM, DI water) indicated by arrows, and the regression of the normalized currents in the insets (n = 3), for PEDOT:PSS-gated OECTs (a) and carbon-gated OECTs (b). The same Y-axis scale was used for all the ions tested.
