1. A piezoelectric sensor, comprising:
a substrate;
an active layer, the active layer being disposed at a side of the substrate;
a first electrode, the first electrode being disposed at a side of the active layer away from the substrate, and the first electrode comprising a plurality of sub-electrodes disposed at intervals;
a piezoelectric layer, the piezoelectric layer being disposed at a side of the first electrode away from the active layer; and
a second electrode, the second electrode being disposed at a side of the piezoelectric layer away from the first electrode, wherein
the active layer is configured to be capable of switching between an insulating state and a conducting state, and in the conducting state, the active layer is capable of conducting the plurality of sub-electrodes.
