不过，从实验室走向现实，这项技术仍面临不少挑战。目前其驱动方式依赖液体浸泡，在一定程度上限制了便携性与环境适应性。“我们已发现电化学手段也能驱动类似薄膜发生溶胀。”多希表示，“未来若能实现全电子化控制，将极大拓展应用场景。”此外，目前制备工艺所需的电子束光刻技术成本高昂。研究团队正在探索更经济的制备方法，如紫外光刻或大面积热加工技术，以期推动规模化应用。。Line官方版本下载对此有专业解读
But in the worst-case scenario, the Deorbit Vehicle won’t be ready. Without it, a protocol agreed on in 2024, which relies on the Russian Progress spacecraft, could come into play. There will be vexing trade-offs to consider.
