A novel platinum (Pt) nano-leaf interfacial layer between the Pt substrate and iridium oxide (IrO) coating, significantly reduced impedance and increased cathodic charge storage capacity (CSC) for neural microelectrodes. Combining the advantages of both materials, herein a lower impedance and higher CSC of IrO/Pt nano-leaf composite coatings than each simple coating was fabricated with nanoscale roughness. Furthermore, it demonstrated excellent mechanical and electrochemical stability, which was beneficial for effective neural stimulation/recording in various applications.
在铂(Pt)基底和氧化铱(IrO)涂层之间形成的新型铂(Pt)纳米叶界面层,显著降低了神经微电极的阻抗并提高了阴极电荷存储容量(CSC)。结合两种材料的优点,本文制备了具有纳米级粗糙度的IrO/Pt纳米叶复合涂层,其阻抗低于单一涂层且CSC高于单一涂层。此外,它还表现出优异的机械和电化学稳定性,这有利于在各种应用中进行有效的神经刺激/记录。
