A device for collecting and processing an electromyography signal of a human body. The device comprises: an electrode module (100, 200, 300), configured to collect an electromyography signal of a human body. The electrode module includes a base structure (103, 203, 303) and at least two electrodes (101, 102, 201, 202, 204, 301, 302, 304, 305), and the at least two electrodes (101, 102, 201, 202, 204, 301, 302, 304, 305) are arranged at intervals on a surface of the base structure (103, 203, 303).
