虽然大多数动物在其一生中都保持相同的视觉外观，但有些物种具有适应性系统，可以改变颜色、图案或纹理以进行防御、信号传递、温度调节或繁殖。其中许多功能激发了具有可调光学和机械性能的材料和设备的开发。然而，当前的仿生变色系统通常仅限于独立控制视觉感知的单个方面，需要新材料或复合材料能够在具有实际能量需求的集成硬件的控制下同时执行多种光学、电气或机械功能。在这个视角中，我们研究了自然界中的变色系统，并讨论了源自这些系统或受这些系统启发的材料和设备的当前状态。此外，我们还讨论了新型多功能材料或设备的重要设计和性能标准，这些材料或设备可以在下一代仿生技术中感知和显示颜色和形态。
While most animals retain the same visual appearance over their lifetime, some species feature adaptive systems that enable changes in color, pattern, or texture for defense, signaling, temperature regulation, or reproduction. Many of these features have inspired the development of materials and devices with tunable optical and mechanical properties. However, current bio-inspired color-changing systems are often limited to controlling single facets of visual perception independently, necessitating new materials or composites that can perform multiple optical, electrical, or mechanical functions simultaneously under the control of integrated hardware with practical energy requirements. In this Perspective, we examine color-changing systems in nature and discuss the current state of materials and devices derived from or inspired by these systems. Additionally, we discuss important design and performance criteria for new multifunctional materials or devices that may sense and display both color and morphology in next-generation bio-inspired technologies.
