A highly reliable neural interface is required in long-term neural signal recording in vivo for neuroscience research and the treatment of neurological disorders. Organic poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) is a promising candidate for a next-generation neural interface material due to its better faradaic charge transfer and capacitive charge coupling than metal electrodes such as Au or Pt. However, its weak adhesion to underlying metallic layers impedes its application with significant cracks or delamination. Here, a MEMS-compatible strategy is proposed to obtain wrinkled microelectrodes based on oil-pretreated elastomer substrate to improve the electrochemical performance and stability of electroplated PEDOT:PSS coating. To discover the optimized electroplating parameters, the galvanostatic electroplating method is applied with incremental time from 0 to 500 s. The modified wrinkled microelectrodes with electroplating time of 300 s permit...

通过优化电镀的PEDOT：PSS实现稳定的软神经接口的微皱纹策略

在体内长期的神经信号记录中，需要高度可靠的神经接口，用于神经科学研究和神经系统疾病的治疗。有机聚（3,4-乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）是下一代神经界面材料的有希望的候选物，因为其比金属电极（例如Au或Pt）更好的法拉第电荷转移和电容性电荷耦合。然而，其对下面的金属层的弱粘附性阻碍了其显着的裂纹或分层的应用。在这里，提出了一种MEMS兼容策略来获得基于经过油预处理的弹性体基底的起皱微电极，以改善电镀PEDOT：PSS涂层的电化学性能和稳定性。要发现优化的电镀参数，恒电流电镀法的使用时间为0到500 s。修饰的起皱微电极，电镀时间为300 s，可实现...
