The research objective of this EArly Concepts Grant for Exploratory Research (EAGER) award is to develop methods for modeling and design of lamina emergent mechanisms (LEMs). These special types of compliant mechanisms are fabricated from planar materials (lamina) but are able to produce motion that emerges out of the fabrication plane. The research will result in methods which are general enough to apply across multiple size regimes and that can be exploited in diverse applications. The research approach progresses from the development of simple components and basic mechanisms, to the creation of devices capable of complex motions and sophisticated tasks. LEM components and basic mechanisms will be designed, fabricated, and tested to validate the models, identify weaknesses, and demonstrate results. Deliverables include a catalog of fundamental components and basic mechanisms, modeling and analysis tools, demonstration and validation via hardware, documentation of research results, engineering student education, and engineering research experiences for pre-service teachers.If successful, the results of this research will provide an opportunity to create compact, cost-effective devices that are capable of accomplishing sophisticated mechanical tasks. Example applications include orthopedic implants that have specified motion characteristics but are small during insertion, and microelectromechanical systems with precise out-of-plane motion. Devices made possible by the research will offer the advantages of planar fabrication, a flat initial state, and monolithic composition. The results will be disseminated to allow the creation of commercial devices that have increased precision, reduced cost, reduced weight, and improved recyclability. Graduate and undergraduate engineering students and pre-service teachers will benefit through classroom instruction and involvement in the research. Students studying to be 6-12 technology and pre-engineering teachers will be engaged to provide them firsthand research experience that they can draw on throughout their teaching careers.

探索性研究早期概念资助（EAGER）奖的研究目标是开发层状应急机制（lem）的建模和设计方法。这些特殊类型的柔性机构由平面材料（薄片）制成，但能够产生出制造平面的运动。这项研究将产生足够通用的方法，适用于多种尺寸制度，并可以在各种应用中加以利用。研究方法从简单部件和基本机构的发展，到能够完成复杂运动和复杂任务的设备的创造。登月舱组件和基本机制将被设计、制造和测试，以验证模型，识别弱点，并展示结果。交付成果包括基本组件和基本机制目录、建模和分析工具、硬件演示和验证、研究成果文档、工程学生教育和职前教师的工程研究经验。如果成功，这项研究的结果将提供一个机会，创造紧凑的，具有成本效益的设备，能够完成复杂的机械任务。示例应用包括具有特定运动特性但在插入时很小的骨科植入物，以及具有精确的面外运动的微机电系统。这项研究使器件成为可能，将提供平面制造、平面初始状态和单片组成的优点。研究结果将被传播，以允许制造精度更高、成本更低、重量更轻、可回收性更好的商业设备。工程专业的研究生和本科生以及职前教师将通过课堂教学和参与研究而受益。学习成为6-12岁的技术和工程预科教师的学生将参与为他们提供第一手的研究经验，他们可以在他们的教学生涯中借鉴。
