Abstract: A flexible electromyographic electrode array and a preparation method therefor, and an electromyographic signal collection apparatus and an electrophysiological signal collection method. The flexible electromyographic electrode array includes: a flexible substrate (100); several liquid metal electrodes, wherein the liquid metal electrodes are arranged on the flexible substrate (100), and the liquid metal electrodes each include a wire and a circuit board connection pattern (110) which is located at one end of a wire (120); and several electrode contacts (130), wherein each of the electrode contacts (130) is connected to the other end of the wire (120), and the electrode contacts (130) are made of a contact solution which contains a hydrophilic polymer and a poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate.
