Abstract

The manipulation of soft morphing robots using external electric fields and wireless control is challenging. Electric field-driven soft morphing matter, termed electro-morphing gel (e-MG), that exhibits complex multimodal large-scale deformation (showing up to 286% strain, and strain rates up to 500% s⁻¹) and locomotion under external electric fields applied using compact and lightweight electrodes is presented. The distinctive capabilities of e-MG derive from the combination of an elastomeric matrix and nanoparticulate paracrystalline carbon. The material properties, electroactive principle, and control strategies are explored and demonstrate fundamental morphing matter behaviors including rotating, translating, stretching, spreading, bending, and twisting. A range of potential bio-inspired applications, including slim mold-like spreading, snail-like jumping over a gap, object transport, wall climbing, and a frog tongue-inspired gripper is shown. The e-MG provides morphing capabilities beyond the current limitations in wireless control for a wide range of applications in soft and bio-inspired robotics, dexterous manipulation, and space exploration.

电场驱动软变形物质

利用外电场和无线控制对柔性变形机器人进行操纵具有挑战性。电场驱动的软变形物质，被称为电变形凝胶（e-MG），呈现出复杂的多模态大规模变形（显示高达286%的应变，应变率高达500% s−1），并在使用紧凑和轻质电极施加的外电场下运动。e-MG的独特能力源于弹性基体和纳米颗粒准晶碳的结合。探讨了材料特性、电活性原理和控制策略，并展示了基本的变形物质行为，包括旋转、平移、拉伸、扩散、弯曲和扭曲。展示了一系列潜在的仿生应用，包括细长的像霉菌一样的扩散，像蜗牛一样跳过缝隙，物体运输，爬墙，以及青蛙舌头的抓取器。e-MG提供了超越当前无线控制限制的变形能力，广泛应用于软体和仿生机器人、灵巧操作和太空探索。
