Electronic textiles (e-textiles) and wearable computing have been emerging increasingly during the last decade. Since the market interest and predictions have grown, the research into increasing reliability and durability of wearables and e-textiles is developing rapidly. The washability of different integration methods and resistance to mechanical stress are the main obstacles being tackled. However, the freedom of movement and overall comfort is still often overlooked during the development phase. It is essential to see the e-textile product as a whole and consider several aspects of user experience. This work will focus on developing and improving the thermoplastic polyurethane (TPU) lamination integration method for e-textiles. In the work, a stretchable copper-polyimide based circuit was laminated onto knit fabric using various TPU films and stacks. The study shares measurable characteristics to determine which material assembly and design would ensure the highest durability for the electronics part without losing its original textile softness, flexibility and stretchability.
在过去的十年中，电子纺织品（e-textiles）和可穿戴计算技术日益兴起。由于市场关注度和预测不断增长，对提高可穿戴设备和电子纺织品可靠性和耐用性的研究也在迅速发展。不同集成方法的可洗性和对机械应力的抵抗力是正在解决的主要障碍。然而，在开发阶段，运动自由度和整体舒适度往往被忽视。将电子纺织品产品视为一个整体，并考虑用户体验的几个方面至关重要。这项工作将专注于开发和改进电子纺织品的热塑性聚氨酯（TPU）层压集成方法。在这项工作中，使用各种 TPU 薄膜和叠层将可拉伸的铜聚酰亚胺基电路层压到针织织物上。该研究分享了可衡量的特性，以确定哪种材料组件和设计将确保电子部件具有最高的耐用性，而不会失去其原始纺织品的柔软度、灵活性和可拉伸性。
