EFRI-ODISSEI: Multi-field Responsive Origami Structures - Advancing the Emerging Frontier of Active Compliant Mechanisms

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）奖的研究目标是开发折纸结构的设计方法，这些折纸结构可以在多个领域（如电、热、磁）的响应下，从最初的平面主动折叠成复杂的三维形状。它们也会主动展开，这与目前必须手动展开的折纸结构不同。这些多领域响应的折纸形状将通过与视觉艺术家合作开发，并使用几何建模和折纸数学进行近似和建模。艺术启发的形状将为设计新颖的主动顺应机构提供目标，与预测性多尺度建模和多物理场模拟一起，将指导新活性材料的开发。这种新型的多场响应材料包括微和纳米复合材料，其中粒子的梯度分布可以实现多个外部场之间的耦合，从而允许沿折痕选择性折叠和展开。将开发一个设计优化框架，以整合建模，设计和活性材料的努力，并使系统贸易研究从纳米到宏观尺度。这个项目的成功完成将在几个应用领域培养新颖的概念和设计创新。例如，基于折纸的手术器械将有利于微创手术，在微创手术中，需要毫米级的设备，可以部署在体内来操纵组织。同样，基于折纸的自适应飞机结构、可重构机器人和可部署空间结构将有助于增强任务的多功能性。宾夕法尼亚州立大学、罗文大学和乔治梅森大学之间的暑期学生交换计划和多所大学的顶点设计项目将有助于扩大工程和STEM专业中代表性不足的群体的参与。这项研究还将用于为宾夕法尼亚州州立大学的探索太空博物馆和宾夕法尼亚州立大学的帕尔默艺术博物馆创造互动艺术作品和k -12目标研讨会。

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 develop methods to design origami structures that actively fold from an initially flat sheet to complex three-dimensional shapes in response to multiple fields (e.g., electric, thermal, magnetic). They will also actively unfold, in contrast to current origami structures that must be manually unfolded. These multi-field responsive origami shapes will be developed through collaboration with a visual artist and approximated and modeled using geometric modeling and origami mathematics. The artistically inspired shapes will provide targets for designing novel active compliant mechanisms, which along with predictive multi-scale modeling and multi-physics simulations, will guide the development of new active materials. This new class of multi-field responsive materials includes micro- and nano-enabled hybrids where a graded distribution of particles enables coupling between multiple external fields to allow selective folding and unfolding along creases. A design optimization framework will be developed to integrate the modeling, design, and active materials efforts and enable system trade studies from the nano to the macro scale. Successful completion of this project will foster novel concepts and design innovation in several application areas. For example, origami-based surgical instruments will benefit minimally invasive surgery, where there is a need for mm-scale devices that can deploy inside the body to manipulate tissue. Similarly, origami-based adaptive aircraft structures, reconfigurable robots, and deployable space structures will help enhance mission versatility. A summer student exchange program and multi-university capstone design projects among Penn State, Rowan, and George Mason will help broaden participation of under-represented groups in engineering and STEM majors. The research will also be leveraged to create interactive artistic pieces and K-12-targeted workshops for the Discovery Space Museum in State College, PA and Penn State's Palmer Museum of Art.
