Abstract: The effect of material properties on compliant mechanism were studied in aspects of the deformation ability, dynamic performance, static failure, and fatigue failure. Firstly, the relationship between the material parameters and the maximum deformation, natural frequency of flexible member was analyzed. Then, the influence of material properties on the static failure and fatigue failure of compliant mechanisms was discussed. Finally, the superiority and challenge of the polymeric materials in the design of compliant mechanisms were summarized.

Key words: compliant mechanisms, polymeric material, material properties, characteristics analysis
