Actuators, devices which make things move, play a critical role in applications from aerospace to medical, assembly to transportation. A class of unique "smart materials" relies on molecular-level transformations within the material to create actuators capable of completely scalable motion with molecular-scale precision. In addition, these actuators are lighter, smaller, and have fewer moving parts than their more traditional counterparts like motors or hydraulics. This gives them significant appeal in space applications where volume, mass, and robustness are key features. For example, the Canadian Space Agency is interested in my research on shape control to help enable lightweight "unfoldable" space antennas.

执行器是使物体移动的装置，在从航空航天到医疗，从装配到运输的应用中发挥着关键作用。一类独特的“智能材料”依赖于材料内部的分子水平转换来创建能够以分子尺度精度进行完全可扩展运动的致动器。此外，这些执行器更轻、更小，与传统的同类产品（如马达或液压系统）相比，它们的运动部件更少。这使得它们在空间应用中具有重要的吸引力，因为空间应用的关键特征是体积、质量和坚固性。例如，加拿大航天局对我在形状控制方面的研究很感兴趣，以帮助实现轻量级的“不可折叠”空间天线。
