Abstract

The invention relates to the technical field of neural electrodes, in particular to a flexible neural electrode, a preparation method and equipment. The flexible neural electrode comprises a flexible implantation part and a rear end interface part, the flexible implantation part comprises at least one flexible probe, one end of the flexible probe is connected with the rear end interface part, and the flexible probe is used for being implanted into a deep brain area of a living body; the flexible probe comprises a metal electrode and a flexible supporting layer, and the metal electrode is arranged in the flexible supporting layer; electrode holes are formed in the flexible supporting layer, and the metal electrodes are exposed out of the flexible supporting layer through the electrode holes to form electrode points; and the flexible supporting layer is made of polyimide. According to the flexible neural electrode, the implantation depth and the transverse coverage area are increased on the device structure, polyimide is adopted as the flexible supporting layer, and the electrode structure is manufactured through the MEMS technology. The flexible neural electrode has good biocompatibility, and can be applied to clinical research aiming at use scenes of being implanted into deep brain areas such as hippocampus and the like.

Description

technical field [0001] The invention relates to the technical field of nerve electrodes, in particular to a flexible nerve electrode, a preparation method and equipment. Background technique [0002] In the field of biological scientific research, biological monitoring plays an important role in the scientific research and diagnosis of various organs. Taking brain science as an example, EEG monitoring plays an irreplaceable role in brain science research, brain disease diagnosis and the development of brain-computer interface technology. Brain monitoring technology can collect EEG signals to help decode brain function. The methods for EEG signal acquisition mainly rely on brain electrodes. There are three widely used brain electrodes: scalp brain electrodes (EEG), cortical brain electrodes (ECoG) and depth brain electrodes (SEEG). [0003] There have been many results for scalp brain electrodes and cortical brain electrodes applied outside the scalp or in the superficial b...
