A wristband-type biological signal acquisition device (200) and a manufacturing method therefor. Said device comprises a wristband (201, 301), a micro-needle array (202, 3022) formed on a micro-needle array substrate, and a biological signal output interface (303), the micro-needle array (202, 3022) being fixed on the wristband (201, 301) and being in contact with the wearer's wrist skin, and the biological signal output interface (303) being connected to an electrode of the micro-needle array (202, 3022), so as to output an acquired biological signal. The wristband-type biological signal acquisition device (200) has a low cost, and is simple to use, convenient to carry, safe and comfortable, and a user can wear said device for a long time so as to continuously and stably record biological signals when the user is stationary or in motion. |
