电子纱线和纺织品的想法已经出现了相当长的一段时间，但它们的性能往往不符合实际的期望。除了化学/机械耐久性和高导电性外，重要的材料资格还包括可织性、耐磨性、重量轻和“智能”功能。在这里，我们展示了一个简单的过程，将普通商品棉线转化为智能电子纺织品，使用基于聚电解质的碳纳米管（CNT）涂层。通过纳米管网络（20 Ω/cm）的有效电荷传输和工程隧道结的可能性使它们成为许多高知识含量服装的有前途的材料。沿着集成湿度传感，我们证明CNT-棉线可用于检测白蛋白，血液的关键蛋白质，具有高灵敏度和选择性。尽管未来的挑战，这些概念验证演示提供了一个直接的途径，这些材料作为可穿戴生物监测和远程医疗传感器，这是简单的，灵敏的，选择性的，和通用的应用。
The idea of electronic yarns and textiles has appeared for quite some time, but their properties often do not meet practical expectations. In addition to chemical/mechanical durability and high electrical conductivity, important materials qualifications include weavablity, wearability, light weight, and "smart" functionalities. Here we demonstrate a simple process of transforming general commodity cotton threads into intelligent e-textiles using a polyelectrolyte-based coating with carbon nanotubes (CNTs). Efficient charge transport through the network of nanotubes (20 Omega/cm) and the possibility to engineer tunneling junctions make them promising materials for many high-knowledge-content garments. Along with integrated humidity sensing, we demonstrate that CNT-cotton threads can be used to detect albumin, the key protein of blood, with high sensitivity and selectivity. Notwithstanding future challenges, these proof-of-concept demonstrations provide, a direct pathway for the application of these materials as wearable biomonitoring and telemedicine sensors, which are simple, sensitive, selective, and versatile.
