Abstract: An electronic device and a bioelectrical signal acquisition method are provided. The electronic device includes a rear housing, a plurality of first contact electrodes, and a plurality of second contact electrodes. A first contact area and a second contact area are distributed on the rear housing. The plurality of first contact electrodes/second contact electrodes are spaced on the rear housing respectively and electrically connected to each other. The first contact electrode and the second contact electrode are used for contacting with the skin respectively to form a bioelectrical signal acquisition circuit. At least one first contact electrode and at least one second contact electrode are distributed in the first contact area, and at least one first contact electrode and at least one second contact electrode are distributed in the second contact area.
