The use of fractal-inspired geometric designs in electrical interconnects represents an important approach to simultaneously achieve large stretchability and high aerial coverage of active devices for stretchable electronics. The elastic stiffness of fractal interconnects is determined analytically in this paper. Specifically, the elastic energy and the tensile stiffness for an order n fractal interconnect of arbitrary shape are obtained, and are verified by the finite element analysis and experiments.
分形启发的几何设计在电互连中的应用是实现可拉伸电子产品中大拉伸性和高有源器件覆盖率的重要方法。本文从理论上分析了分形互连的弹性刚度。具体地,得到了任意形状的 n 阶分形互连的弹性能量和拉伸刚度,并通过有限元分析和实验进行了验证。
