Carbon nanotubes were grown on flexible polyimide substrates at temperatures below 400 °C as electrodes for extracellularly neuronal recording. The electrical charge‐transfer and electrochemical properties of such CNT electrodes were enhanced by UV‐ozone exposure, which induced the formation of CO, CO, and OCO bonds and reduced the CNT/electrolyte interfacial impedance while increasing the interfacial capacitance.
