The invention provides an anisotropic magnetic nano piezoelectric material and a preparation method thereof, and aims to solve the technical problem that in the prior art, a nano piezoelectric material cannot sense directional pressure. According to the invention, a ferroferric oxide suspension and a dimethyl siloxane monomer solution are mixed, wherein the selected materials are simple and controllable, and no waste is generated in the mixing process; then a curing agent is added for curing, to the surface of a glass slide is coated, magnetization treatment is performed to enable the magnetic particles of the second solution coated on the surface of the glass slide to have certain directivity under the action of a magnetic field, and then drying is performed to remove moisture to obtain the anisotropic magnet nano piezoelectric material; and the anisotropic magnet nano piezoelectric material obtained by the preparation method can sense pressure in different directions. 本申请提供了一种各向异性磁性纳米压电材料及其制备方法，解决了现有技术中纳米压电
