The invention discloses a nanometer displacement performer. Graphene oxide film (2) and a film upper bearing surface (2) are arranged on the upper surface of a substrate (3) in sequence, thereby forming a displacement transmission bearing body. The film upper bearing surface is taken as a displacement transmission bearing surface. Two ends of the displacement transmission bearing body are equipped with a sealing wall (4) of a left sealing cavity and the sealing wall (5) of a right sealing body. An environment atmosphere output control pipeline port (6) is arranged at the outer end of the sealing wall of the left sealing cavity. An environment atmosphere input control pipeline port (7) is arranged at the outer end of the sealing wall of the right sealing cavity. A left sliding contact device (8) is arranged between the inner end of the sealing wall of the left sealing cavity and the displacement transmission bearing body. A right sliding contact device (9) is arranged between the inner end of the sealing wall of the right sealing cavity and the displacement transmission bearing body. The micro-displacement performer provides a novel and efficient method which applies to various application occasions.
