Flexible unsmoothed cuticles of soil animals and their characteristics of reducing adhesion and resistance

Based on observing and analyzing the typical soil animals, the flexible unsmoothness is defined, which is the moving unsmoothness made by the flexible deformation of the structural units, and its characteristics of reducing adhesion and resistance is analyzed. The tests show that on the same conditions, compared with 45 Steel, the adhesion of the field-mouse’s fur is reduced by about 35%, its sliding resistance is reduced by about 80%.
