Synthetic systems cannot easily mimic the color-changing abilities of animals such as cephalopods. Soft machines--machines fabricated from soft polymers and flexible reinforcing sheets--are rapidly increasing in functionality. This manuscript describes simple microfluidic networks that can change the color, contrast, pattern, apparent shape, luminescence, and surface temperature of soft machines for camouflage and display. The color of these microfluidic networks can be changed simultaneously in the visible and infrared--a capability that organisms do not have. These strategies begin to imitate the functions, although not the anatomies, of color-changing animals.
合成系统很难模仿头足类动物等动物的变色能力。软机器——由软聚合物和柔性增强片材制造的机器——的功能正在迅速增加。本文描述了简单的微流控网络，这些网络可以改变软机器的颜色、对比度、图案、明显形状、发光和表面温度，以实现伪装和显示。这些微流控网络的颜色可以在可见光谱和红外光谱中同时改变——这是生物体所不具备的能力。这些策略开始模仿变色动物的功能，而不是它们的解剖结构。
