The invention discloses an intelligent magnetic drive self-repairing flexible pressure sensor and a preparation method therefor. According to the scheme of the invention, the method comprises the steps: preparing a silver nanowire and linear needle-shaped magnetic nickel; forming a high-molecular base material with a self-repairing function through combination; mixing the silver nanowire and linear needle-shaped magnetic nickel, adding the mixture to the base material, and carrying out the crosslinking, solidifying and film forming; packaging a self-repairing flexible film, placing the self-repairing flexible film into a magnetic field for magnetizing orientation, and obtaining the intelligent magnetic drive self-repairing flexible pressure sensor. The method is advantageous in that 1, the silver nanowire and linear needle-shaped magnetic nickel are compounded, the linear needle-shaped structure can be effectively configured with the silver nanowire, and a conduction circuit is more effective; 2, the magnetic drive self-repairing flexible pressure sensor employs a dimer acid as a monomer unit, thereby enabling a prepared self-repairing flexible film to be excellent in mechanical performance; 3, the magnetic field is applied to the die, thereby enabling the anisotropic magnetic nickel to be oriented in the high-molecular base material, and achieving the intelligent magnetic drive.
