Figure 4. — (a) The pH sensitivity of four IrO_x-based electrodes with an electrode size of 500 μm × 500 μm versus a standard Ag/AgCl RE; (b) Sensitivities of IrO_x-based electrodes with sizes of (#1) 1 mm × 1 mm, (#2) 500 μm × 500 μm, and (#3) 100 μm × 100 μm were 57 ± 1.1, 53 ± 1.8 and 47 ± 1.4 mV/pH, respectively.
