With the rapid development of Internet of Things (IoT) and bioscience technology, wearable smart devices are developing toward advanced trends such as flexibility, convenience and environmental-friendliness. Poly (p-styrenesulfonic acid) (PSS), as a common template and dispersant, is indispensable in the polymerization of conductive polymers. However, the doping amount of PSS has a significant effect on the electrical conductivity of the polymer. Herein, different molar quantities of PSS were used to assist the polymerization of 3,4-ethylenedioxythiophene (EDOT) monomer in a horseradish peroxidase/hydrogen peroxide (HRP/HO) low-temperature system to obtain conductive finishing solutions with more excellent electrical properties. Then, the polyester nonwoven fabric was immersed in the conductive finishing solution, and when the addition ratio of EDOT and PSS was 1:2, the conductive performance was optimal (3.27 KΩ cm). Finally, the conductive fabric was assembled into a pressure sensor and a temperature sensor, which can transmit Morse code in the form of single-parameter (pressure response or temperature response) or collaboration. Overall, this research has great potential for production of poly(3,4-ethylenedioxythiophene) (PEDOT)-based composites and their applications in smart wearable device.
随着物联网（IoT）和生物科学技术的快速发展，可穿戴智能设备正朝着柔性、便捷和环保等先进趋势发展。聚（对苯乙烯磺酸）（PSS）作为一种常见的模板和分散剂，在导电聚合物的聚合过程中不可或缺。然而，PSS的掺杂量对聚合物的电导率有显著影响。在此，使用不同摩尔量的PSS在辣根过氧化物酶/过氧化氢（HRP/H₂O₂）低温体系中协助3,4-乙撑二氧噻吩（EDOT）单体聚合，以获得具有更优异电学性能的导电整理液。然后，将聚酯无纺布浸入导电整理液中，当EDOT与PSS的添加比例为1:2时，导电性能最佳（3.27 KΩ·cm）。最后，将导电织物组装成压力传感器和温度传感器，它们能够以单参数（压力响应或温度响应）或协同的形式传输莫尔斯电码。总体而言，本研究在基于聚（3,4-乙撑二氧噻吩）（PEDOT）的复合材料生产及其在智能可穿戴设备中的应用方面具有巨大潜力。
