Animals can modify their body shape and/or color for protection, camouflage and communication. This adaptability has inspired fabrication of actuators with structural color changes to endow soft robots with additional functionalities. Using liquid crystal-based materials for actuators with structural color changes is a promising approach. In this review, we discuss the current state of liquid crystal-based actuators with structural color changes and the potential applications of these structural color actuators in soft robotic devices.

基于液晶的结构颜色致动器

动物可以改变它们的身体形状和/或颜色以进行保护、伪装和交流。这种适应性激发了制造具有结构颜色变化的致动器的灵感，以赋予软机器人额外的功能。将基于液晶的材料用于具有结构颜色变化的致动器是一种很有前途的方法。在这篇综述中，我们讨论了具有结构颜色变化的基于液晶的执行器的当前状态以及这些结构颜色执行器在软机器人设备中的潜在应用。
