从理论上和实验上研究了一种非共面网格设计，使电子系统能够实现大的、可逆的水平拉伸性（>100%）。该设计在弹性衬底上使用半导体器件岛和弯曲薄互连。建立力学模型是为了理解潜在的物理原理，并指导这种系统的设计。在不进行参数拟合的情况下，预测的屈曲幅值与实验值吻合较好，误差在5.5%以内。结果还给出了互连和孤岛中的最大应变，以及整个系统的拉伸性和压缩性。(C) 2009年美国物理研究所。(DOI: 10.1063/1.3148245)
A noncoplanar mesh design that enables electronic systems to achieve large, reversible levels stretchability (>100%) is studied theoretically and experimentally. The design uses semiconductor device islands and buckled thin interconnects on elastometric substrates. A mechanics model is established to understand the underlying physics and to guide the design of such systems. The predicted buckle amplitude agrees well with experiments within 5.5% error without any parameter fitting. The results also give the maximum strains in the interconnects and the islands, as well as the overall system stretchability and compressibility. (C) 2009 American Institute of Physics.
