在弹性衬底上形成条状的薄金膜，并带有内置的压应力，以形成表面波。因为这些波可以被拉伸为平坦的，它们起到了弹性电导体的作用。令人惊讶的是，我们观察到的电连续性不仅高达2%的外部应变，首先拉伸薄膜平整(类似于0.4%)，然后拉伸独立金膜的断裂应变(类似于1%)，但高达22%。如此大的应变将使制造对三维电子电路至关重要的可伸缩导体成为可能。(C)2003年美国物理研究所。
Stripes of thin gold films are made on an elastomeric substrate with built-in compressive stress to form surface waves. Because these waves can be stretched flat they function as elastic electrical conductors. Surprisingly, we observe electrical continuity not only up to an external strain of similar to2% reached by stretching the films first flat (similar to0.4%) and then to the fracture strain of free-standing gold films (similar to1%), but up to similar to22%. Such large strains will permit making stretchable electric conductors that will be essential to three-dimensional electronic circuits. (C) 2003 American Institute of Physics.
