The integration of thermoelectric (TE) device on fabrics is a challenge. Instead of using adhesive tape to fix traditional filmlike TE devices onto the fabrics, which sacrifices the breathability of fabrics, here we report a flexible TE fiber based on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/tellurium nanowires (Te NWs) composites, which can be woven and integrated into the fabric directly. The TE fibers have a tunable content and orientation of Te NWs and also the potential to be scaled up based on the wet-spinning process. The TE fibers exhibit desirable wearable TE performances, including high power factor (78.1 μW m^–1 K^–2), high mass-specific power (9.48 μW g^–1), excellent mechanical flexibility, and superior integrability.

高度可集成的热电纤维。

在织物上集成热电（TE）设备是一个挑战。在此我们报告了一种基于聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）/的柔性TE纤维，而不是使用胶带将传统的薄膜状TE设备固定到织物上，这会牺牲织物的透气性。碲纳米线（Te NWs）复合材料，可以将其编织并直接集成到织物中。TE纤维具有可调节的Te NW含量和取向，并且还具有基于湿纺工艺扩大规模的潜力。TE纤维表现出理想的可穿戴TE性能，包括高功率因数（78.1μWm ^–1 K ^-2），高质量比功率（9.48μWg ^–1），出色的机械柔韧性和出色的集成性。
