Helicies are found at every level of biology and are used by biology to perform many important functions. Here we want to design artificial materials that are capable of making mechanical movements observed in plants. These movements include spring-like functionality, unwinding and helical inversion. The materials will operate by light driven nano-scopic movements, which will then be translated into an overall shape in the material. We will use these shape changes to do mechanical work. There is currently no clear knowledge as to how to convert light driven nano-scale movement into macroscopic work and so this research will lay important groundwork. The ultimate aim of this research is not just to reproduce the movements observed in nature, but more importantly to use the lessons in the design and testing process to establish fundamental rules for how molecular scale movement can be translated to the macroscopic scale, and how this behaviour can be tuned rationally. These results may find applications in the development of new energy conversion or storage devices. Other potential applications include micro-mechanical, fluidic and robotic systems as well as sensors, mechanical muscles and materials capable of moulding the flow of light.

在每个级别的生物学水平上都发现了螺旋液，并被生物学用于执行许多重要功能。在这里，我们要设计能够在植物中观察到的机械运动的人造材料。这些动作包括春季的功能，放松和螺旋反转。这些材料将通过轻驱动的纳米散布运动运行，然后将其转化为材料中的整体形状。我们将使用这些形状更改进行机械工作。目前尚无关于如何将光驱动纳米级运动转化为宏观工作的知识，因此这项研究将奠定重要的基础。这项研究的最终目的不仅是重现自然界观察到的运动，而且更重要的是要在设计和测试过程中使用课程来建立基本规则，以使分子量表运动如何转化为宏观尺度，以及如何理性地调整这种行为。这些结果可能会在开发新的能源转换或存储设备的开发中找到应用。其他潜在的应用包括微型机械，流体和机器人系统以及传感器，机械肌肉和能够塑造光流的材料。
