Although there are many studies on bionic textures and MFSAs respectively, the combination of bionic textures and MFSAs has not yet been reported. In this study, it is shown in section 2 that the surface structure of the tree frog's toe pads was got through a scanning electron microscope. Then the edge extraction algorithm was used and drawn a conclusion that the hexagon is the dominant shape on the surface of the tree frog's toe pads. Subsequently, the MFSAs with and without hexagonal surface textures were designed. In section 3, firstly, the oscillation system was simplified and the motion equations were obtained. Fortunately, vortexes generated in the MF layers closed to the wall with surface textures have been observed by simulation analysis. Simultaneously, the shear rate of the MF significantly increases when surface textures are added to the wall. In section 4, the vibration reduction experiments were conducted on different MFSAs, which were fabricated by 3D printing. In the end, the experimental results indicate that the existing of bionic textures obviously enhances the damping efficiency of MFSAs, while the size of bionic textures has a little effect.
