电介质弹性体的一层在其厚度上施加电压时会扩大其面积。通过使用图案化的预拉伸、电极和加强筋，该层可以被编程为在三维中变形。为了辅助这种可编程变形的设计，本文描述了一种计算方法，利用规定电压设置标称电场的事实。文中以皱纹的形成、手形驱动器的运动和气球的非线性振动为例进行了验证。
A layer of a dielectric elastomer expands its area when a voltage is applied across its thickness. The layer can be programed to deform in three dimensions by using patterned prestretches, electrodes, and stiffeners. To aid the design of such programmable deformation, this paper describes a computational method, exploiting the fact that the prescribed voltage sets the nominal electric field. The method is demonstrated with examples including formation of wrinkles, movements of a handlike actuator, and nonlinear oscillation of a balloon.
