The invention discloses a wafer-level solar sail spacecraft capable of detecting space dust and tiny fragments. The wafer-level solar sail spacecraft comprises a solar sail film, a high-reflectivity metal electrode coating, a double-layer micro metal beam element, a rigidity enhancing truss, a limiting frame and a flexible circuit control board. The solar sail film is petal-shaped, the center of the front face of the solar sail film is an effective load integration area, the flexible circuit control board is arranged in the effective load integration area, an isolation belt is arranged in the middle of the front face of each petal, the front faces of the petals on the two sides of the isolation belt are coated with high-reflectivity metal electrode coatings, and the double-layer micro metal beam elements stretch across the isolation belts. The two ends of the high-reflectivity metal electrode are fixed on the high-reflectivity metal electrode coating; the upper-layer metal beam of the double-layer micro-metal beam element is heated expansion metal, and the lower-layer metal beam is heated contraction metal; a rigidity enhancing truss and a piezoelectric sensor are arranged on the back surface of the solar sail film; and the flexible circuit control board independently loads different high and low voltages to each high-reflectivity metal electrode coating.
