Figure 3

Voltage transient of fully deinsulated SIROF in response to the cathodal first, charge balanced biphasic current pulse in PBS. The iridium oxide working electrode, Ag/AgCl reference electrode and platinum counter electrode were immersed in PBS. The current pulse amplitude was 100 µA with length of 1 ms. The figure illustrates the maximum cathodic potential (Emc = −0.6V) and maximum anodic potential (Ema = 0.7V) during the pulse. The charge injection capacity was obtained by integrating current with time.
