Natural bio-based fibers consist of a large amount of hydrogen bonds between intra and inter macromolecules that offer a basis for switch required in shape memory behaviors. This work reports our advance in understanding the bio-based fibers with shape memory in keratin hairs, β-sheeted filaments, chitosan and collagen fibers. Qualitative and quantitative study of such fibers was carried out in terms of their structure, shape fixation and recoverability under cyclic deformation programming. The effects of hydration on recovery dynamic mechanical behaviors and structural components were all systematically studied. Hybrid structural network models with switch net points will be presented for interpreting the shape memory mechanism of bio-based fibers. This kind of discoveries of biobased fibers is surely expected to provide inspiration for exploring other natural materials to reveal their smart functions and making more remarkable synthetic smart materials as well as widening the applications of existing materials
