提出了一种在平面制造步骤中创建具有嵌入式驱动的复杂结构的方法。自组织和能量最小化是这种方法的核心，说明了一个模型的基础上最小化的超弹性自由能应变函数的拉伸弹性体和弯曲弹性能的塑料框架。一个郁金香形的夹具结构说明了该方法的技术潜力。优点是制造简单、最终结构复杂、以及任何电活性材料可以容易地用作致动装置。(c)2007年，美国物理学会。
An approach for creating complex structures with embedded actuation in planar manufacturing steps is presented. Self-organization and energy minimization are central to this approach, illustrated with a model based on minimization of the hyperelastic free energy strain function of a stretched elastomer and the bending elastic energy of a plastic frame. A tulip-shaped gripper structure illustrates the technological potential of the approach. Advantages are simplicity of manufacture, complexity of final structures, and the ease with which any electroactive material can be exploited as means of actuation.
