(a) CV curves of Au grid, ITO island/Au grid, and ITO/Au grid microelectrodes at 100 mV/s. (b) Electrical benchtop recording output of a 10 Hz, 20 mV peak-to-peak input sine wave in a PBS solution from an ITO/Au grid hybrid microelectrode. (c) Power spectral density of the recorded sine wave from the ITO/Au grid hybrid microelectrode in (b). (d) Variation of impedance versus soaking time for an encapsulated ITO/Au grid hybrid microelectrode. Z0 is the impedance before soaking test whereas Z represents the impedance on a specific day.
