The objective of this Faculty Early Career Development (CAREER) Program award is to enable design for integrity in Shape-Shifting Surfaces (SSSs), i.e., surfaces which retain their effectiveness as a physical barrier while undergoing changes in shape. These shape changes could be motions (e.g., expanding, shrinking, twisting, encircling, wiggling, swallowing or constricting), which would make the surface more effective at performing its function. The SSSs are a new invention, and are composed of tiled arrays of polygonal cells, each cell consisting of flexures attached to overlapping thin plates or shells. The research will develop techniques for using these surfaces to achieve a specified shape shift, for mechanized motion of the surface, and for sensing the loads that are applied to the surface.This research will enable engineers to create more dynamic, responsive surfaces. In the short term, demonstration of this technology will be achieved in recreational and commercial applications, such as a foldable kayak, a weight-measuring floor, and an SSS-based robot. In the long term, devices with biomedical or military significance, such as artificial heart muscles and flexible body armor, will be pursued. Teaching innovation will be achieved through projects that reach under-graduate and graduate engineers and through thought-provoking educational and recreational products that target both K-6 students specifically, and a wider audience in the general public.

该学院早期职业发展（Career）计划奖的目标是使变形表面（sss）的完整性设计成为可能，即在形状发生变化时保持其作为物理屏障的有效性的表面。这些形状的变化可以是运动（例如，扩张、收缩、扭曲、环绕、摆动、吞咽或收缩），这将使表面更有效地发挥其功能。SSSs是一项新发明，由多边形细胞的平铺阵列组成，每个细胞由附着在重叠的薄板或壳上的弯曲组成。该研究将开发使用这些表面来实现特定形状转换的技术，用于表面的机械化运动，以及用于感知施加在表面上的负载。这项研究将使工程师们能够创造出更动态、更灵敏的表面。在短期内，这项技术的演示将在娱乐和商业应用中实现，例如可折叠皮艇，称重地板和基于sss的机器人。从长远来看，将追求具有生物医学或军事意义的设备，如人造心脏肌肉和柔性防弹衣。教学创新将通过面向本科生和研究生工程师的项目，以及针对K-6学生和广大公众的发人深省的教育和娱乐产品来实现。
