Novel organic electrically conductive organic fibers (ECFs) have been fabricated using a facile, economical and scalable technique by staining nonconductive fibers (both natural and synthetic) with a conductive ink composed of two intrinsically conductive materials, i.e., single walled carbon nanotubes (SWCNTs) and regioregular poly(3-hexylthiophene) (rr-P3HT). These organic ECFs exhibit low resistance of 0.50 kΩ cm^–1 with a conductive ink composed of 0.8 mg/mL of SWCNTs and 1.6 mg/mL of P3HT while maintaining the mechanical properties of the original fibers. These organic ECFs were characterized by resistance measurements, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy and stress–strain measurements. Finally, the recording properties of the organic ECFs were examined by both electromyography and electrocardiography in terms of the signal-to-noise ratio, which was found to be similar and/or exceeded the data obtained by standard metal electrodes.

有机导电纤维作为非金属电极和神经互连

新型有机导电有机纤维（ECF）已使用一种简便，经济且可扩展的技术通过用由两种固有导电材料（即单壁碳纳米管（SWCNT））组成的导电油墨对非导电纤维（天然和合成）进行染色而制成和区域规则的聚（3-己基噻吩）（rr-P3HT）。这些有机ECF表现出0.50kΩcm ^–1的低电阻使用由0.8 mg / mL的SWCNT和1.6 mg / mL的P3HT组成的导电油墨，同时保持原始纤维的机械性能。这些有机ECF的特征在于电阻测量，拉曼光谱，扫描电子显微镜，透射电子显微镜和应力应变测量。最后，通过肌电图和心电图检查信噪比，从而检查了有机ECF的记录特性，发现信噪比相似和/或超过了标准金属电极获得的数据。
