Modelling analysis of rough surface contact for biomimetic gecko adhesion array

By combining linear beam theory and the height distribution of rough surface, a theoretical contact model of adhesion force between biomimetic gecko adhesion array and rough surface is developed to obtain a better understanding of the array-surface interaction and to design a better biomimetic gecko adhesion array. Meanwhile the relationship between the elastic energy and adhesion energy is discussed before getting the model. Finally a design of a biomimetic gecko adhesion array with active control ability is proposed in brief.
