With rapid development of coexisting-cooperative-cognitive robot and advanced micro/nano-manufacturing technique, the concept of soft micro/nanorobots is proposed and attract more and more attentions in recent years. The special properties of micro/nanoscale materials and structures under complex microfluidic environments drive the development of flexible reconfigurable micro/nanorobots that have unique advantages, such as small movement resistance, strong environmental adaptation, high control flexibility, etc. The achievement on its core technologies that can active, controllable and reversible switches of the functional structures between multiple stable configurations, termed multimodal shape morphing, has important significance in biomedical applications. This project intends to develop smart printable materials and advanced micro/nano-manufacturing technology for fabricating flexible stimulus-responsive micro/nanorobots, and explore the mechanical properties and deformation mechanism of flexible smart materials by using micro/nano mechanical testing and finite element analysis method. With the aid of advanced micro/nano manufacturing technology and structure-functional design method, the complex shape-morphing design and optimization strategy of flexible micro/nano robot will be further investigated. By studying the deformation mechanism, actuation method and control strategy of multimodal shape morphing under the coupling of multi-physical and chemical fields, the effective methods of design, fabrication and optimization of material-structure-actuation-functional integration will be explored. The current researches will provide reliable theoretical and technical supports for potential biomedical applications of soft micro/nanorobots.
