Stretchable Textile Electronics with Printing (STEP)

电子纺织品已经在电影中出现了几十年，从《回到未来》()中的马蒂·麦克弗莱的自动烘干夹克到最近的《一号玩家》(2018年)中的可穿戴触觉西装。之所以这些设备中的许多都是科幻小说，而不是科学事实，是因为在将电子产品转移到纺织品上时，仍然有许多工程问题需要解决。纺织二维旨在通过创新目前用于制造电子纺织品的材料和技术来解决这些问题。为了制造电子纺织品，电子墨水将被配方，然后使用可伸缩打印技术，如喷墨打印或卷到卷打印，打印到纺织品表面。我们将用来制造电子墨水的材料被称为石墨烯，这是一种由单原子厚度的碳原子组成的蜂窝结构。与传统金属相比，使用石墨烯的优势在于它更可持续、更轻、更灵活，而且潜在的成本要低得多。然而，在纺织品上构建电子元件的另一个关键参数是电子元件与纺织纤维之间的稳定性。纺织二维将与国家物理实验室合作，改善电子墨水的稳定性。国家物理实验室将帮助为可穿戴设备的稳定性制定新的国家测量标准，同时还将通过实验测量和分析帮助解决与纺织品上电子元件断裂有关的关键问题。

Electronic textiles (e-textiles) has been seen in movies for decades, from Marty McFly's self-drying jacket in Back to the Future (1989) to the more recent wearable haptic suits in Ready Player One (2018). The reason many of these devices are science fiction and not science fact is that there are still many engineering issues which need to be solved when moving electronics onto textile. Textile Two Dimensional aims to solve these issues through innovating the materials and technology which is currently used to build electronic textiles. To make the e-textile, electronic inks will be formulated and then printed onto textile surfaces using scalable printing techniques such as inkjet printing or roll-to-roll printing. The material we will use to make the electronic ink is known as graphene, a honeycomb arrangement of carbon atoms which is a single atom thick. The advance of using graphene over traditional metals is that it that it is more sustainable, lighter, flexible and potentially much lower cost. However another key parameter of building electronics on textile is the strechability of the electrical components with the textile fibres. Textile Two Dimensional will partner with the National Physical Laboratory to improve the strechability of electronic inks. The National Physical Laboratory will help to develop new national measurement standards for the strechability of wearable devices while also helping to solve key issues related to the fracturing of electronic components on textile through experimental measurement and analysis.
