Abstract

Animal diaphragm-lung systems are soft organs that generate a controllable vacuum. Elephants, as rare land animals, can manipulate all three states of matter using their lung-generated vacuum. In soft robotics, however, current vacuum generation relies on rigid components, and no single soft device effectively handles all states of matter. Traditional soft pumps and grippers are limited in scope: soft pumps provide continuous liquid flow but cannot directly manipulate solids, while grippers manage solids but are ineffective with liquids and gases. Inspired by lung functionality, we present a soft pressure-to-vacuum converter that provides precise control over the suction, holding, and release of solids, liquids, and gases through a single entry and exit point based on negative pressure. Through the selection of appropriate material properties and design variations, our soft device achieves vacuum levels up to -18 kPa, enabling intermittent control and sequential handling of various media without the need for additional components. We demonstrate diverse applications of our soft device, including artificial lungs, liquid blending, vacuum gripping, coffee preparation, and liquid-gas vaporization. This bioinspired device not only provides a safe and adaptable solution for vacuum generation but also addresses a critical gap in soft robotics, offering a multifunctional system capable of manipulating all states of matter.
生物启发真空产生通过压力到真空转换操纵物质的所有阶段。
动物的膈肺系统是产生可控真空的软器官。大象作为一种稀有的陆地动物,可以利用肺部产生的真空来控制物质的这三种状态。然而,在软机器人中,目前的真空产生依赖于刚性部件,没有一个软设备能有效地处理物质的所有状态。传统的软泵和夹持器范围有限:软泵提供连续的液体流动,但不能直接操纵固体,而夹持器管理固体,但对液体和气体无效。受肺功能的启发,我们提出了一种软压力-真空转换器,通过基于负压的单一入口和出口点,可以精确控制固体、液体和气体的吸入、保持和释放。通过选择适当的材料特性和设计变化,我们的软设备可实现高达-18 kPa的真空水平,实现间歇控制和各种介质的顺序处理,而无需额外的组件。我们展示了我们的软设备的各种应用,包括人工肺,液体混合,真空夹持,咖啡制备和液气蒸发。这种受生物启发的装置不仅为真空产生提供了一种安全、适应性强的解决方案,而且还解决了软机器人技术的一个关键空白,提供了一个能够操纵物质所有状态的多功能系统。
