Embroidery is often the preferred technology when rigid circuit boards need to be connected to sensors and electrodes by data transmission lines and integrated into textiles. Moreover, conventional circuit boards, like Lilypad Arduino, commonly lack softness and flexibility. One approach to overcome this drawback can be flexible sequins as a substrate carrier for circuit boards. In this paper, such an approach of the development of flexible and functional sequins and circuit boards for wearable textile applications using subtractive and additive technology is demonstrated. Applying these techniques, one-sided sequins and circuit boards are produced using wax printing and etching copper-clad foils, as well as using dual 3D printing of conventional isolating and electrically conductive materials. The resulting flexible and functional sequins are equipped with surface mounted devices, applied to textiles by an automated embroidery process and contacted with a conductive embroidery thread.
当刚性电路板需要通过数据传输线连接到传感器和电极并集成到纺织品中时，刺绣通常是首选技术。此外，传统电路板，如Lilypad Arduino，通常缺乏柔软性和灵活性。克服这一缺点的一种方法可以是使用柔性亮片作为电路板的基板载体。本文展示了一种使用减法和加法技术开发用于可穿戴纺织品应用的柔性和功能性亮片及电路板的方法。应用这些技术，通过蜡印和蚀刻覆铜箔以及使用传统绝缘和导电材料的双3D打印来生产单面亮片和电路板。所得的柔性和功能性亮片配备有表面贴装器件，通过自动刺绣工艺应用于纺织品，并与导电刺绣线接触。
