1. A microfluidic chip, comprising a first substrate; wherein the first substrate comprises a first base and a first electrode layer on the first base; the first electrode layer comprises a plurality of first electrodes arranged at intervals along a first direction, wherein a cross-sectional shape of the first electrode parallel to the first base is a centrosymmetric shape, and the cross-sectional shape comprises a first boundary and a second boundary opposite to each other in the first direction;
a shape of the first boundary is a centrosymmetric curve, a distance between two end points of the first boundary in a second direction perpendicular to the first direction is less than a length of the first boundary; and
the second boundary has a same shape and length as the first boundary, and the first boundary and the second boundary are parallel to each other in the first direction.
