The development of neural electrodes has received increasing attention in areas such as biomedical engineering

neuroscience

and related clinical medicine. Traditional neural electrodes face electrical signal failures

resulting in a series of tissue responses. In order to make the nerve probe-nerve interface with good electrical properties

to ensure its long-term effectiveness

we need to use the surface coating to modify the electrode

including to modify the electrode microstructure or to find new materials. Conductive polymers are easy to synthesize and own conductive performance and good biocompatibility

the electrochemical performance could be improved significantly by coating of conductive polymers and their composites. The recent progress of conductive polymers as neural electrode coating is introduced in this paper.
