Electronic fibres have been considered one of the desired device platforms due to their dimensional compatibility with fabrics by weaving with yarns. However, a precise connecting process between each electronic fibre is essential to configure the desired electronic circuits or systems. Here, we present an integrated electronic fibre platform by fabricating electronic devices onto a one-dimensional microfibre substrate. Electronic components such as transistors, inverters, ring oscillators, and thermocouples are integrated together onto the outer surface of a fibre substrate with precise semiconductor and electrode patterns. Our results show that electronic components can be integrated on a single fibre with reliable operation. We evaluate the electronic properties of the chip on the fibre as a multifunctional electronic textile platform by testing their switching and data processing, as well as sensing or transducing units for detecting optical/thermal signals. The demonstration of the electronic fibre suggests significant proof of concepts for the realization of high performance with wearable electronic textile systems.
由于电子纤维可通过与纱线编织实现与织物的尺寸兼容性，因此被视为理想的设备平台之一。然而，每根电子纤维之间精确的连接过程对于配置所需的电子电路或系统至关重要。在此，我们通过在一维微纤维基板上制造电子设备，展示了一个集成电子纤维平台。诸如晶体管、逆变器、环形振荡器和热电偶等电子元件，通过精确的半导体和电极图案，集成在纤维基板的外表面上。我们的结果表明，电子元件可以集成在单根纤维上并可靠运行。我们通过测试其开关和数据处理以及用于检测光/热信号的传感或转换单元，将纤维上芯片的电子特性评估为多功能电子纺织平台。电子纤维的展示为实现高性能可穿戴电子纺织系统提供了重要的概念验证。
