Abstract: A micro-nano fluid damper includes a sleeve, a piston assembly and a micro-nano fluid. The sleeve has an accommodating space. The piston assembly has a piston head and at least one piston rod. The piston assembly is movably disposed in the accommodating space. The piston rod extends out of the sleeve from a side of the piston head. The micro-nano fluid is filled between the sleeve and the piston assembly, and the micro-nano fluid flows in the accommodating space by the back-and-forth movement of the piston. When a shear strain rate of the micro-nano fluid is greater than 1s−1, an exponent of velocity of the micro-nano fluid damper is less than 1, and the micro-nano fluid has a shear thinning threshold and a shear thickening threshold.
