Abstract

The invention provides an electrode array and a preparation method thereof. The electrode array comprises a bottom base, a conductive layer and a face base, wherein the conductive layer is arranged on the bottom base. The face base partially covers the conductive layer so as to form an exposed electrode point. The water absorbing property of the bottom base is different from that of the face base so that the electrode array can absorb water inside a biological body to form a curled structure, and therefore the research and treatment of specific diseases can be achieved.

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 microelectrodes 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, microelectrodes are mainly Michigan electrodes based on MEMS technology. Michigan electrodes are mostly two-dimensional silicon-based hard electrodes with a single structure and style, which cannot be curled, and cannot fully meet the research and treatment of diseases. Contents of the invention [0003] The invention provides an electrode array and a preparation method thereof. By setting a bottom substrate and a face ...
