This grant provides funding for a CAREER award. The principal goal of this project is to develop systematic design methods for the shape synthesis of mechanical structures subject to unconventional actuation. The following three synthesis problems will be addressed: (1) Synthesis of novel micro- and meso-scale devices with embedded electro-thermal-compliant actuation such that they deform desirably upon applying an voltage differential between two points; (2) Synthesis of a structure for prescribed normal mode shapes; and (3) Shape synthesis of piezoelectrically driven structures. In each case, the coupled interactions among the field equations of multiple energy domains will be modeled and used in conjunction with the numerical optimization methods to develop the optimal synthesis algorithms. The educational plan includes involving undergraduates in research, and developing design-oriented graduate courses and a curriculum for graduate and undergraduate students in the rapidly growing area of Micro-Electro-Mechanical Systems (MEMS). A new outreach activity of `Taking MEMS to high schools` is included as part of this integrated research and education activity to inspire and encourage high school students to pursue careers in science and technology. If successful, this research will result in design methodologies for optimizing shape to exploit the full potential of materials and unconventional actuations used in modern mechanical systems such as MEMS and Smart Structures. This will impact the MEMS, and micro-sensor and actuator industries making their products more competitive because of improved quality and lower cost. The successful implementation of the educational plan of this project will result in mechanical engineering graduates with interdisciplinary skills for the 21st century.

该补助金为职业奖提供资金。 这个项目的主要目标是开发系统的设计方法的形状合成的机械结构受到非常规驱动。 将解决以下三个合成问题：（1）合成新型的微型和中型规模的设备与嵌入式电热顺应性的驱动，使他们变形时，两点之间施加电压差;（2）合成的结构，规定的正常模式形状;和（3）形状合成的压电驱动结构。 在每种情况下，多个能量域的场方程之间的耦合相互作用将被建模，并与数值优化方法结合使用，以开发最佳的合成算法。 该教育计划包括让本科生参与研究，并在快速发展的微电子机械系统（MEMS）领域为研究生和本科生开发以设计为导向的研究生课程和课程。 作为这项综合研究和教育活动的一部分，还包括一项新的外联活动“将MEMS带到高中”，以激励和鼓励高中生从事科学和技术职业。 如果成功，这项研究将导致优化形状的设计方法，以充分利用现代机械系统（如MEMS和智能结构）中使用的材料和非常规驱动的潜力。 这将影响MEMS、微传感器和执行器行业，使其产品因质量提高和成本降低而更具竞争力。 该项目教育计划的成功实施将为21世纪培养具有跨学科技能的机械工程毕业生。
