纺织工业拥有先进的工艺，允许计算机化制造具有精确视觉图案的大批量服装。然而，该行业无法使用其精确的制造方法（如计算机刺绣）大规模制造带有无缝集成可穿戴传感器的衣服。这是由于缺乏与工业中使用的标准制造方法兼容的导电线。在这项工作中，我们报告了一种低成本的聚（3，4-乙撑二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）改性棉导电线（PECOTEX），是兼容的电脑刺绣。PECOTEX使用PEDOT：PSS和棉线之间的交联反应，使用二乙烯基砜作为交联剂来生产。我们对配方进行了广泛的表征和优化，以制造出机械性能坚固的导电线，可以卷对卷方式大量生产。使用PECOTEX和家用电脑刺绣机，我们生产了一系列可穿戴的电传感器，包括用于监测呼吸的面罩，用于监测心脏活动的T恤和用于监测氨的基于纺织品的气体传感器作为技术演示。PECOTEX有潜力大规模生产集成到日常服装中的新型低成本可穿戴传感器。
The textile industry has advanced processes that allow computerized manufacturing of garments at large volumes with precise visual patterns. The industry, however, is not able to mass fabricate clothes with seamlessly integrated wearable sensors, using its precise methods of fabrication (such as computerized embroidery). This is due to the lack of conductive threads compatible with standard manufacturing methods used in industry. In this work, we report a low-cost poly(3,4-ethylenediox ythiophene) polystyrene sulfonate (PEDOT:PSS)-modified cotton conductive thread (PECOTEX) that is compatible with computerized embroidery. The PECOTEX was produced using a crosslinking reaction between PEDOT:PSS and cotton thread using divinyl sulfone as the crosslinker. We extensively characterized and optimized our formulations to create a mechanically robust conductive thread that can be produced in large quantities in a roll-to-roll fashion. Using PECOTEX and a domestic computerized embroidery machine, we produced a series of wearable electrical sensors including a facemask for monitoring breathing, a t-shirt for monitoring heart activity and textile-based gas sensors for monitoring ammonia as technology demonstrators. PECOTEX has the potential to enable mass manufacturing of new classes of low-cost wearable sensors integrated into everyday clothes.
