Considering the dependence of photomechanical responses of liquid crystal elastomers on the director orientation, the performance controlling through director orientation design becomes possible. In this article, a programmable liquid crystal elastomer matrix is proposed to achieve the desired functions. First, a modeling framework about the spontaneous bending of liquid crystal elastomer square plate with arbitrary director orientation is developed. Three kinds of spontaneous bending configurations are obtained along with the variation of the director orientation, and the critical division of the director orientation is given. Based on the deformation characteristic, the director orientation of the liquid crystal elastomer matrix is programmed and several typical prototypical functions, such as 3D code or image display, are discussed. This work provides the guidance for the application of the liquid crystal elastomer in haptic display, braille display, remotely‐controlled actuators, and codes.

通过光机械响应可编程液晶弹性体矩阵
考虑到液晶弹性体的光机械响应对指向矢取向的依赖性,通过指向矢取向设计来控制性能成为可能。在本文中,提出了一种可编程液晶弹性体基体,以实现所需的功能。首先,建立了关于具有任意指向矢方向的液晶弹性体方板自发弯曲的建模框架。随着指向矢方向的变化,获得了三种自发的弯曲构型,并给出了指向矢方向的临界划分。根据变形特性,对液晶弹性体矩阵的指向矢进行编程,并讨论了几种典型的原型功能,例如3D代码或图像显示。
