The invention discloses and provides a neural microprobe for dual-mode function positioning and precise electrical stimulation of deep brain nuclei of non-human primates. The probe is composed of a substrate layer, a metal conductive layer and an insulating layer, and the conductive layer comprises a detection site group and a stimulation site. The silicon oxide material on the back surface of the silicon substrate layer is simultaneously subjected to dry etching by adopting the double insulating layers with opposite stress, the stress difference of different materials is balanced, the technical difficulty of a lengthened silicon microprobe is overcome, and the problems that the probe is easy to bend and the mechanical stress is small due to the large length-width ratio of a silicon probe of a non-human primate animal are solved. A detection site obtains a dual-mode signal as a positioning mark by modifying a nano-metal material and a polymer anti-interference ionic membrane for functional ...
