电子纺织刺绣最近正在成为铜的一种极具前景的替代品，用于需要灵活性、一致性和坚固性的各种应用(可穿戴设备、军事、智能家居等)。长期以来，研究人员一直在对比电子纺织品导电表面和铜基导电表面的性能。然而，一些电磁(EM)组件，如线圈或线天线，依赖于导线而不是导电片/表面。在这项工作中，我们报告了在整个1 kHz到10 GHz范围内，用于电磁应用的电子线和铜线的第一次比较。在低频下，e线和铜线制成的线圈表现出类似的自感和互感，尽管e线的电阻值要高出2到9倍。在高频下，由电子线和铜线制成的传输线表现出很好的一致性。值得注意的是，与铜相比，电子螺纹的重量要轻4倍以上。未来，这些发现可以被用来将各种铜线EM组件转化为电子纺织品。
E-textile embroidery is recently emerging as a highly promising substitute to copper for diverse applications that require flexibility, conformality and robustness (wearables, military, smart homes, and more). Studies have long contrasted the performance of e-textile conductive surfaces vs. their copper-based counterparts. However, several electromagnetic (EM) components, such as coils or wire antennas, rely on conductive wires rather than conductive sheets/surfaces. In this work, we report the first comparison of e-threads vs. copper wires for EM applications across the entire 1 kHz to 10 GHz range. At low frequencies, coils made of e-threads and copper wires show similar self and mutual inductance, though resistance values are 2 to 9 times higher for e-threads. At high frequencies, transmission lines made of e-thread and copper wire show good agreement. Notably, e-threads are over 4 times more lightweight as compared to copper. In future, these findings can be leveraged to translate various copper-wire EM components into e-textiles.
