Abstract

The invention provides an electrode array and a preparation method thereof. The electrode array comprises a plurality of first electrode beams and at least one second electrode beam, wherein the first electrode beams are longitudinally arranged; the second electrode beam is horizontally arranged; each of the first electrode beams comprises an electric conductor and an insulating layer wrapped on the electric conductor; one end of the electric conductor is used for connecting an electrode array interface; the other end of the electric conductor is exposed, so that an electrode point is formed; the electrode point is used for collecting or transmitting an electric signal; the second electrode beam has a curl structure; and the first electrode beams are fixed on the second electrode beam, so that the electrode array with a three-dimensional network structure is supplied and the requirement of a special experiment is met.

Description

technical field [0001] The invention relates to the technical field of microelectrodes, in particular to an electrode array and a preparation method thereof. Background technique [0002] Electrophysiology is an important research method in neuroscience. By implanting electrodes in specific brain regions of model animals, scientists can record electrophysiological signals under different stimulation conditions, or study the relationship between specific behaviors of model animals and the discharge patterns of electrophysiological signals. At present, microelectrode arrays are mainly Michigan electrodes based on MEMS technology. Michigan electrodes are mostly two-dimensional silicon-based hard electrodes with a relatively simple structure and style, which cannot fully meet specific experimental needs. Contents of the invention [0003] The invention provides an electrode array and a preparation method thereof, which can provide an electrode array with a three-dimensional ...
