基于银纳米线(AgNW)的导体是一种很有前途的柔性和可拉伸电子器件。最近已经展示了一系列使用AgNW导体的柔性/可伸展器件。高分辨率、高通量的AgNW印刷仍然是一个严峻的挑战。电液动力(EHD)打印是一种很有前途的技术，可以在各种衬底上以高分辨率打印不同的材料。在这里，AgNW油墨是为EHD打印开发的。印刷特性可以通过AgNW浓度、油墨粘度、印刷速度、离距等参数来控制。利用这种方法，可以在纸张、聚对苯二甲酸乙二酯(PET)、玻璃、聚二甲基硅氧烷(PDMS)等基材上印刷AgNW图案。首先，在PDMS上对AgNW样品进行弯曲和拉伸表征。然后，制作了AgNW加热器和心电电极，以展示这种打印技术在基于AgNW的柔性和可伸缩设备中的潜力。
A silver nanowire (AgNW) based conductor is a promising component for flexible and stretchable electronics. A wide range of flexible/stretchable devices using AgNW conductors has been demonstrated recently. High-resolution, high-throughput printing of AgNWs remains a critical challenge. Electrohydrodynamic (EHD) printing has been developed as a promising technique to print different materials on a variety of substrates with high resolution. Here, AgNW ink was developed for EHD printing. The printed features can be controlled by several parameters including AgNW concentration, ink viscosity, printing speed, stand-off distance, etc. With this method, AgNW patterns can be printed on a range of substrates, e.g. paper, polyethylene terephthalate (PET), glass, polydimethylsiloxane (PDMS), etc. First, AgNW samples on PDMS were characterized under bending and stretching. Then AgNW heaters and electrocardiogram (ECG) electrodes were fabricated to demonstrate the potential of this printing technique for AgNW-based flexible and stretchable devices.
