Abstract

The invention relates to the technical field of brain-computer interfaces, in particular to a flexible neural electrode packaging structure, a preparation method and equipment. Comprising at least two stacked planar flexible neural electrode arrays; the planar flexible neural electrode array comprises a substrate and a packaging substrate. The front surface of the substrate is connected with the front surface of the packaging substrate; the projection of the packaging substrate on the horizontal plane and the projection of the substrate on the horizontal plane at least partially do not coincide; at least part of the edge of the back face of one packaging substrate is connected with at least part of the edge of the front face of the other packaging substrate. According to the flexible neural electrode packaging structure, the planar flexible neural electrodes are integrated, and a 3D stacked packaging flexible neural electrode array covering a large area is achieved. The two-dimensional flexible neural electrode array is packaged and integrated in a three-dimensional mode to obtain the integrated 3D flexible neural electrode array, and the integrated 3D flexible neural electrode array can be used for achieving high-density and high-spatial-resolution neural signal collection of a brain area.

Description

technical field [0001] The invention relates to the technical field of brain-computer interfaces, in particular to a flexible neural electrode packaging structure, a preparation method and equipment. Background technique [0002] Brain-computer interface refers to the technology that connects the brain with external devices to realize information interaction, which has important research significance for the exploration of brain science and the diagnosis and treatment of brain diseases. Neural electrodes are the core components of brain-computer interfaces and can be divided into two types: invasive and non-invasive. In contrast, non-invasive neural electrodes (such as head-worn EEG caps) indirectly obtain weak EEG signals through the brain scalp, and invasive electrodes directly contact nerve tissue, which can obtain high-precision and high-sensitivity neuronal information, which has aroused researchers' interest. extensive attention. [0003] Invasive neural electrodes c...
