STRUCTURE AND BIONICS OF SEVERAL SETAE

The setae on the surface of animals have different forms and functions,which make up of the sensory organs or the sporting organs.The functions of the setae in locomotion are different due to their various structures.The structure of the cockroach(Periplaneta americana) cercus and its bionic application,the mechanism walking on the water surface of the water strider(Gerris remigis) and fishing spider(Dolomedes trition) by its setae with strong hydrophobicity,the adhesion mechanism of spider(Evarcha arcuata) and gecko(Gecko japoricus,Gekko gecko) foot hair,the anti-adherent functions and bionic applications of the dung beetle(Copris ochus,Motschulsky) setae et al.were mainly introduced in this paper.
