Progress in bionic research on biomaterials of beetles

Evolving for millions of years, the biomaterials of beetles have developed an optimized st ructure with
excellent mechanical performance, elaborate and rigid geomet ry shape and multifunctional surface texture, which makes it become one of the new object s in bionics. In this paper, the progress in bionic research was reviewed on the microst ructure of biomaterials, the mechanical performance, the functional morphology and the geomet ry shape in topology. The research status of biomaterials (including the beetle claw, the elyt ra and the wing) was summarized, also the problems existing in each work were discussed while the research emphases were prospected in future in the correlative area.
