随着人们对可穿戴电子产品的兴趣越来越大，在织物上构建电子电路仍然具有挑战性。在不同的方法中，纤维状电化学晶体管潜在地适用于各种应用，特别是生物电子学。基于光纤的器件越来越受欢迎，因为它们的制造成本低，重量轻，机械灵活性，而不会失去它们作为传感器和晶体管的特性。在这项工作中，我们研究了由两个导电线与凝胶电解质制成的有机电化学晶体管。当晶体管暴露于酸性溶液时，测试晶体管，然后显示漏极电流的变化。测试漏极和源极之间的导电线的结果揭示了pH对在晶体管设计中用作半导体材料的PEDOT：PSS涂层的影响。这一结果对于新型低成本、柔性生物电子传感器件的应用具有重要意义。
With the increasing interest in wearable electronics, still, building electronic circuits on fabrics is challenging. Among different approaches, fiber shape electrochemical transistors are potentially suitable for various applications, particularly for bioelectronics. Fiber-based devices are getting popular because of their low fabrication cost, lightweight, and mechanical flexibility without losing their properties as sensors and transistors. In this work, we have studied an organic electrochemical transistor made from two conductive threads with a gel electrolyte. The transistor was tested when it was exposed to an acidic solution which then showed a change in the drain current. The results from testing the conductive thread between the drain and source reviled the effect of the pH on the PEDOT:PSS coating used as the semiconducting material in the transistor design. The results are encouraging for the applications in new low-cost, flexible bioelectronics sensing devices.
