Artificial skins with functions such as sensing, variable stiffness, actuation, self-healing, display, adhesion, and camouflage have been developed and widely used, but artificial skins with escape function are still a research gap. In nature, every species of animal can use its innate skills and functions to escape capture. Inspired by the behavior of fish-scale geckoes escaping predation by shedding scales when grasped or touched, we propose a flexible escape skin by attaching artificial scales to a flexible film. Experiments demonstrate that the escape skin has significant effects in reducing escape force, escaping from harmful force environments, and resisting mechanical damage. Furthermore, we enabled active control of escape force and skin hardness by changing temperature, increasing the adaptability of the escape skin to the surrounding. Our study helps lay the foundation for engineering systems that depend on escape skin to improve robustness.

受鳞片脱落防御行为启发而设计的灵活逃生皮肤。

具有传感、变刚度、驱动、自愈、显示、粘附、伪装等功能的人造皮肤已被开发出来并得到广泛应用，但具有逃生功能的人造皮肤仍然是一个研究空白。在自然界中，每种动物都可以利用其与生俱来的技能和功能来逃脱捕获。受到鱼鳞壁虎在抓握或触摸时脱落鳞片来逃避捕食的行为的启发，我们提出了一种灵活的逃生皮肤，将人造鳞片附着在柔性薄膜上。实验证明，逃生蒙皮在降低逃生力、逃离有害力环境、抵抗机械损伤等方面具有显着效果。此外，我们还可以通过改变温度来主动控制逃逸力和表皮硬度，提高逃生表皮对周围环境的适应性。我们的研究有助于为依赖逃逸表皮来提高稳健性的工程系统奠定基础。
