实用的可穿戴电子纺织品必须耐用，并尽可能保持纺织品的特性，如悬垂性，手感，轻便，透气性和耐洗性，使织物适合服装。早期的电子纺织服装是通过将标准的便携式电子设备插入定制的口袋并在服装上布置互连和布线来实现的。在这些例子中，纺织品只是作为一种载体来容纳电子产品，并没有固有的电子功能。电子元件尺寸的减小、柔性电路的发展以及编织鲁棒互连的能力为纺织品内的电子集成水平的提高提供了潜力。介绍了将小于2mm宽的电子电路丝编织成织物，使得电子器件完全隐藏在织物中，并由周围的织物纤维给予额外的保护。不同的灯丝电路设计之前和之后集成到纺织品的故障机制进行了研究与90度循环弯曲试验。结果表明，嵌入纺织品中的封装长丝电路经受住了45次洗涤循环和超过1500次围绕10 mm弯曲半径的90度弯曲循环，其性能比集成到织物中之前的等效长丝电路好五倍。
Practical wearable e-textiles must be durable and retain, as far as possible, the textile properties such as drape, feel, lightweight, breathability, and washability that make fabrics suitable for clothing. Early e-textile garments were realized by inserting standard portable electronic devices into bespoke pockets and arranging interconnects and cabling across the garment. In these examples, the textile merely served as a vehicle to house the electronics and had no inherent electronic functionality. A reduction in electronic component size, the development of flexible circuits, and the ability to weave robust interconnects offer the potential for improved levels of electronic integration within the textile. The weaving of electronic circuit filaments less than 2 mm wide into fabrics such that the electronics are fully concealed in the textile and given extra protection by the surrounding textile fibers is introduced. The failure mechanisms for different filament circuit designs before and after integration into the textile are investigated with a 90 degrees cyclical bending test. Results show that encapsulated filament circuits embedded within the textile survive 45 washing cycles and more than 1500 cycles of 90 degrees bending around a bending radius of 10 mm, performing five times better than equivalent filament circuits before integration into the fabric.
