In this paper,we introduce several kinds of neural microelectrode which have been widely used at present and compare the advantage and disadvantage of the techniques and methods for producing neural microelec trode.Finally we refer to existent problems and possible resolved projects in the chronic neural microelectrode.From manual microelectrode and push equipment to microelectrode array using the semiconductor and MEMS techniques,they have established an important foundation for chronic neural electrophysi...
