EFRI-ODISSEI: Photo-Origami

这项研究与创新前沿（EFRI）“工程创新自组装系统集成折纸设计”（ODISSEI）奖的研究目标是创造一种名为“照片折纸”的整体方法，通过一系列光激活折叠和变形步骤，将平坦的聚合物片转化为机械坚固的3D结构。这种新的制造方法将通过将形状记忆聚合物、光响应柔性材料和光波导集成到智能帆布中来实现顺序折叠。该研究将开发适用于多个跨学科领域的方法，包括活性材料、光力学、光化学和光学，从而可以在广泛的应用中得到开发。研究方法从基本组成部分的建立和相应机理的认识出发，逐步发展到多物理非线性设计理论，最终达到创作照片折纸的目的。可交付成果包括一套活性物质及其激活方法、多物理模型和设计工具、演示和验证、研究成果文档、工程学生教育、高中生工程研究经验以及研究成果向公众传播。如果成功，这项研究的结果将使制造具有非凡功能的材料和设备的新方法成为可能。示例应用包括具有低重量但高强度或各向异性特性的新型稀疏材料，具有集成电子，射频或光学电路元件的深度3D MEMs。这项研究的制造方法将提供一个平坦的初始状态，功能设备可以很容易地放置和最终复杂的3D结构的优势。研究生和本科生将通过参与研究，在材料科学，力学，光学和设计优化之间进行严格的培训。这项研究还将与当地学区合作，紧密结合到STEM教育和推广活动中，提高公众意识，激励K-12学生。我对STEM很感兴趣。该项目由空军科学研究办公室提供部分资金支持。

The research objective of this Emerging Frontiers in Research and Innovation (EFRI) Origami Design for the Integration of Self-assembling Systems for Engineering Innovation (ODISSEI) award is to create a holistic approach, named photo-origami, to transform a flat polymer sheet into a mechanically robust 3D structure via a sequence of light-activated folding and deformation steps. This new manufacturing approach will be achieved by integrating shape memory polymers, photo-responsive compliant material, and optical waveguides into a smart canvas to enable sequentially folding. The research will develop methods that are applicable to several interdisciplinary fields including active materials, photomechanics, photochemistry, and optics, and thus can be exploited in a wide array of applications. The research approach starts from the establishment of the basic components and the corresponding mechanistic understanding, progresses to the development of multiphysical nonlinear design theory, and achieves the final goal of creating photo origami. Deliverables include a suite of active materials and their activation methods, multiphysical modeling and design tools, demonstration and validation, documentation of research results, engineering student education, engineering research experience for high school students, and dissemination the research achievements to the general public.If successful, the results of this research will enable fundamentally new approaches to manufacture materials and devices with extraordinary functionalities. Example applications include new sparse materials with low weight but high strength or anisotropic properties, deep 3D MEMs with integrated electronic, RF or optical circuit elements. Manufacturing approaches from this research will offer the advantage of a flat initial state where functional devices can be easily placed and a final complicated 3D structure. Graduate and undergraduate students will benefit from a rigorous training at the interface between material science, mechanics, optics, and design optimization through involvement in the research. The research will also be tightly integrated into STEM education and outreach activities by partnering with the local school district to bring public awareness and to inspire K-12 student?s interest in STEM.This project is supported in part by funds from the Air Force Office of Scientific Research.
