  • Abstract
    The electrode-tissue interface plays an important role in neural recordings. Here, we designed and fabricated a flexible electrode array with nanowire structures and poly(3,4-ethylenedioxythiophene) PEDOT on the flexible substrate. ZnO nanowires were used as a nano pillar structure, which increases effective surface area drastically, to decrease electrode impedance. Furthermore, ZnO nanowires was coated with PEDOT to enhance both biocompatibility and charge transfer characteristics. Flexible electrode array with nanowires and PEDOT shows a higher signal-to-noise ratio (SNR).
