许多新兴形式的电子和光电器件都需要将信号从一个电路元件传送到另一个电路元件的柔性、可拉伸和跨越的微电极。我们已经通过在半导体、塑料和玻璃基板上以均匀和高纵横比图案的最小宽度约为2微米的浓缩纳米颗粒油墨的全向印刷来图案化银微电极。图案化的微电极可以承受重复的弯曲和拉伸到大的应变水平，其电性能的退化最小。用这种方法，引线键合到脆弱的三维设备和跨越太阳能电池和发光二极管阵列的互连演示。
Flexible, stretchable, and spanning microelectrodes that carry signals from one circuit element to another are needed for many emerging forms of electronic and optoelectronic devices. We have patterned silver microelectrodes by omnidirectional printing of concentrated nanoparticle inks in both uniform and high-aspect ratio motifs with minimum widths of approximately 2 micrometers onto semiconductor, plastic, and glass substrates. The patterned microelectrodes can withstand repeated bending and stretching to large levels of strain with minimal degradation of their electrical properties. With this approach, wire bonding to fragile three-dimensional devices and spanning interconnects for solar cell and light-emitting diode arrays are demonstrated.
