AI 中文摘要
响应环境压力而改变形状的致动器在从太空到深海的极端环境中具有巨大应用潜力。双层致动器虽具有轻便和机械结构简单等优点，但尚未用于此。本文构建了基于泡沫的由环境压力变化驱动的双层致动器，进行数学建模，表征其驱动力，并将其应用于可展开装置和超材料结构以展示负压膨胀性等特性，适用于多种应用。
英文摘要
Actuators which change shape in response to ambient pressure have great potential for use in extreme environments, from space to the deep ocean. Bi-layer actuators have so far not been explored to this end, despite their lightness and mechanical simplicity (there is no requirement for a separate power source or pump, for example) making them ideal for applications where transport and maintenance are difficult. In this paper, foam-based bilayer actuators powered by ambient pressure change have been constructed, modelled mathematically, characterised in terms of their actuating force, and built into deployable devices and metamaterial structures to showcase properties such as negative pressure expansivity. Actuators such as these are ideally suited for a range of applications, from deploying solar panels and sensors in space and extra-terrestrial atmospheres, to under-sea expandable structures and sensing.
