Figure 3
(a,b) Impedance plot and phase plot of electrochemical impedance spectra (EIS) of the tubular microelectrodes with and without PEDOT/PSS modification, respectively. Msd and Cal in the figure legend referred to the measured result and fitting result by equivalent circuit, respectively. The insertion indicated the equivalent circuit for EIS fitting. (c) Cyclic voltammograms (CV) of the tubular microelectrodes with and without PEDOT/PSS modification. The arrows indicated the cyclic scanning direction. (d) Strain-stress test results of the tubular microelectrode (red) and polyimide capillary (green). The insertion referred to the broken moment on the test equipment. (e) Remain of impedance (red) and CSC (green) of the tubular microelectrodes after repeatedly bending to the angle of 30°, 60° and 90° for 50, 100, 150 and 200 times, separately. (f) Flow resistance tested (green) and calculated (blue) results. The insertion referred to the multi-channel fluidic test equipment.
