Although various biointeractive tools have been suggested such as patch clamp, microelectrode arrays (MEAs), and transistor based sensors, the most effective method is still the planar-typed MEA system due to their high reliability and cost-effectiveness. However, since common bio-interfacial materials such as gold and iridium have poor electrochemical translation efficiency, it is difficult to distinguish the cell signal from the thermal noise. Here, we developed electrochemically durable MEAs based on the crystallized-PEDOT:PSS for in-vitro long-term cell recording. Although, it was simply fabricated with conventional thin film fabrications, we achieved over thirty-fold increase of the electrochemical conductance with high water stability and transparency. Finally, the extracellular bio-potentials could be acquired with high viability and low background noise compared with conventional metal-based MEAs. |
