近年來，可穿戴生理傳感器技術的發展引起了學術界和工業界的廣泛關注。紡織材料與電子元器件的結合已成為智能紡織領域的研究熱點。由於機械運動和與活體組織的長時間接觸可能會造成頻繁的損傷，因此在這些裝置中應用自修復材料就顯得尤為重要。然而，到目前為止，很少有團隊將靜電紡絲技術和自修復電極應用於智能可穿戴設備。本研究將靜電紡絲技術與熱塑性聚氨酯相結合，製備出微納米級纖維，使其具有高比表面積、高孔隙率、耐磨等特點。在 3,4-聚乙烯二氧噻吩：聚苯乙烯磺酸鹽（PEDOT： PSS）導電聚合物溶液中浸涂靜電紡絲纖維，該溶液與還原氧化石墨烯（rGO）和銀納米粒子（AgNPs）混合。PEDOT：PSS賦予導電溶液自修復特性，使纖維電極可以從損壞中恢復到原來的性能，rGO和AgNPs可以形成良好的三維結構和導電路徑，增加電極的導電性和機械強度纖維電極。 Triton X-100具有良好的還原和分散氧化石墨烯性能，此外還可以增強PEDOT：PSS的自修復性能和柔性，此研究所製備的纖維電極具有優異的物理性能（3000次疲勞試驗）、低片電阻 (1.3×101 Ω/sq)及經過200% 應變損壞後的自愈恢復率達到 (98.3%)。總結來說，我們採用系統性方法合成納米銀/碳基材料PEDOT：PSS溶液，並結合靜電紡絲技術，獲得良好的導電性和物理性能，用於智能服裝ECG和EMG測量。與商業電極 Ag/AgCl 信號相比，動態運動過程中產生的 ECG 和 EMG 的穩定性更穩定。可自修復纖維電極更適用於長效穿戴式智能服裝傳感器電極。

In recent years, the development of wearable physiological sensing technology has attracted a lot of attention from academia and industry. The combination of textile materials and electronic components has become the focus of research in the field of smart textiles. Since mechanical movement and prolonged contact with living tissues may cause frequent damage, the application of self-healing materials in these devices is particularly important. However, until now few teams have applied electrospinning technology and self-healing electrode to smart wearable devices. This research combines electrospinning technology and thermoplastic polyurethane to prepare micro-nano-scale fibers and make them have the characteristics of high specific surface area, high porosity, and wear resistance. In this research we dip-coated the electrospinning fiber in 3,4-polyethylene dioxythiophene: polystyrene sulfonate (PEDOT: PSS) conductive polymer solution which mixed with reduced graphene oxide (rGO) and silver nanoparticles (AgNPs). The PEDOT: PSS gives the conductive solution a self-healing property to make the fiber electrode can recover from damage to the original performance, rGO and AgNPs can form a good three-dimensional structure and conductive path to increase the conductivity and mechanical strength of the fiber electrode. The Triton X-100 has a good performance to reduce graphene oxide and disperse it, in addition it can also enhance the self-healing performance and flexibility of PEDOT: PSS. Finally the prepared fiber electrode has excellent mechanical properties (3000-time fatigue tests)、conductivity (1.3×101 Ω/sq) and the self-healing recovery rate after 200% strain reach (98.3%). In conclusion, we use a systematic method to synthesize nano-silver/carbon-based PEDOT: PSS solution and combine it with electrospinning technology to obtain good conductivity and mechanical properties for smart clothe ECG and EMG measurement. The stability of ECG and EMG generated during dynamics exercise are more stable compared to commercial electrodes Ag/AgCl signals. The self-healing fiber electrode is more suitable for long-term wearable smart clothing sensing electrodes.
