Prof. Huiling Duan’s Group Make Progress in the Field of Intelligent Micro/nano-robotics

1. Four-dimensional Direct Laser Writing of Reconfigurable Compound Micromachines (Materials Today, 2020, 32 (1-2): 19-25) was highlighted by Materials Today news titled ‘Laser Makes Micromachines Right’, say ‘There is an inevitable trade-off between deformability and structural complexity, but the new approach allows the construction of complex, reconfigurable micromachines including cages, stents, and lantern-like structures, which display excellent deformation characteristics, transforming rapidly and reversibly from 3D-to-3D shape in response to external stimuli.2’. https://www.materialstoday.com/polymers-soft-materials/news/laser-makes-micromachines-right/

2. Four-dimensional Micro-building Blocks (Science Advances, 2020, 6, eaav8219) was highlighted by TechXplore titled ‘Four-dimensional micro-building blocks: Printable, time-related, programmable tools’4，say ‘T. Y. Huang and colleagues proposed a programmable modular design based on 4D micro-building block assembly to aid complex forward and inverse problems of 4-D printing. They used FEA to predict shape evolution of each building block, without considering the whole structure in order to notably reduce computational complexity. The resulting microscale transformer was capable of complex 3-D transformations based on four DH parameters and a single-step DLW fabrication process using photoresponsive hydrogels. Huang et al. foresee that the proposed modular design will pave the way to facilitate new designs of complex 4-D printing’. https://techxplore.com/news/2020-01-four-dimensional-micro-building-blocks-printable-time-related.html
