In this paper, the washability of wearable textronic (textile-electronic) devices has been studied. Two different approaches aiming at designing, producing, and testing robust washable and reliable smart textile systems are presented. The common point of the two approaches is the use of flexible conductive PCB in order to interface the miniaturized rigid (traditional) electronic devices to conductive threads and tracks within the textile flexible fabric and to connect them to antenna, textile electrodes, sensors, actuators, etc. The first approach consists in the use of TPU films (thermoplastic polyurethane) that are deposited by the press under controlled temperature and pressure parameters in order to protect the conductive thread and electrical contacts. The washability of conductive threads and contact resistances between flexible PCB and conductive threads are tested. The second approach is focused on the protection of the whole system-composed of a rigid electronic device, flexible PCB, and textile substrate-by a barrier made of latex. Three types of prototypes were realized and washed. Their reliabilities are studied.
本文对可穿戴纺织电子设备的可洗性进行了研究。提出了两种旨在设计、生产和测试坚固耐用、可清洗且可靠的智能纺织系统的不同方法。这两种方法的共同点是使用柔性导电印刷电路板，以便将小型化的刚性（传统）电子设备与纺织柔性织物内的导电线和线路连接，并将它们连接到天线、纺织电极、传感器、致动器等。第一种方法是使用通过压力机在受控的温度和压力参数下沉积的TPU薄膜（热塑性聚氨酯），以保护导电线和电触点。测试了导电线的可洗性以及柔性印刷电路板与导电线之间的接触电阻。第二种方法侧重于通过乳胶制成的屏障保护由刚性电子设备、柔性印刷电路板和纺织基材组成的整个系统。实现并清洗了三种类型的原型。研究了它们的可靠性。
