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 ~2 µm 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. Using this approach, wire bonding to fragile 3D devices and spanning interconnects for solar cell and light emitting diode arrays are demonstrated.

中文报道:据《每日科学》网2月21日报道,美国伊利诺伊大学厄本那-香槟分校(UIUC)的研究人员研制出一种由银纳米粒子构成的新型墨水,可应用于电子和光电等领域,创造出更易弯曲和伸展的、跨度较大的微电极,实现信号从一个电路元件到另一个电路元件的传递。这种微电极能经受住反复的弯曲和伸展,自身性能却基本不会发生改变。相关论文发表在2月12日的《科学》。
