A microfluidic chip configured to move a microdroplet along a predetermined path, includes a plurality of probe electrode groups spaced apart along the predetermined path. Each of the plurality of probe electrode groups includes a first probe electrode and a second probe electrode spaced apart from each other. The first probe electrode and the second probe electrode among a plurality of first probe electrodes and a plurality of second probe electrodes are configured to form an electrical loop with the microdroplet to thereby facilitate determining a position of the microdroplet.
