(a) Current and working electrode voltage response waveforms from the charge injection limit analysis. The solid arrow is the 10 μs interphase pulse between the cathodic and anodic phases. The dashed arrow indicates the minimum voltage of the working electrode voltage waveform. This value was used for the charge injection limit analysis. (b) Average post-cathodic voltage of sputtered iridium oxide film during the biphasic capacitive pulse stimulation (n=12). The arrow in the graph indicates the charge injection limit for the iridium oxide electrodes.
