Triboelectric nanogenerator/supercapacitor (TENG-SC) is believed to have great potential for wearable/portable bio-motion energy harvesting/storage electronics, but many TENGs could rarely be satisfactory to wearable electronics because of their poor wearability and complex configurations. Herein, a round-tripping-knitting strategy is devised to directly knit flexible PTFE yarn closing around polydimethylsiloxane/MnO₂ nanowire (PDMS/MnO₂NW)-coated conductive carbon cloth yarns (CCT@PDMS/MnO₂NW) that can be used as wearable TENG textile to harvest bio-motion energy. Superior power generation performance was obtained by modulating the dielectric permittivity of PDMS/MnO₂NW elastomer based on variations in the mass-loading of MnO₂NW. The obtained TENG textile can convert various forms of bio-motion energy into electrical signal and the maximum output voltage of about 380 V can be obtained and easily light up 200 serially connected LEDs. Additionally, all-solid-state yarn-type asymmetric supercapacitor was woven with TENG and act as energy storage unit, which demonstrates high volumetric energy density and excellent cyclic stability. Because of the flexible all yarn-type structure of the entire system, the SC and TENG can be easily woven into cloth to continuously harvest and store bio-motion energy, which demonstrates great convenience and immense applications as wearable, lightweight, comfortable continuous bio-motion energy harvesting/storage device and versatile pressure sensing.

摩擦电纳米发电机/超级电容器（TENG-SC）被认为具有可穿戴/便携式生物运动能量收集/存储电子产品的巨大潜力，但是许多TENG由于其较差的可穿戴性和复杂的配置而很少能满足可穿戴电子设备的需求。在本文中，设计了一种双向编织策略，以直接编织柔性PTFE纱线，该纱线围绕可使用的聚二甲基硅氧烷/ MnO ₂纳米线（PDMS / MnO ₂ NW）涂覆的导电碳布纱线（CCT @ PDMS / MnO ₂ NW）闭合作为可穿戴的TENG纺织品来收获生物运动能量。通过根据MnO的质量负载变化来调节PDMS / MnO ₂ NW弹性体的介电常数，可获得卓越的发电性能₂西北。所获得的TENG纺织品可以将各种形式的生物运动能转换成电信号，并且可以获得大约380 V的最大输出电压，并且可以轻松点亮200个串联的LED。此外，全固态纱线型不对称超级电容器用TENG编织并用作能量存储单元，显示出高的体积能量密度和出色的循环稳定性。由于整个系统都采用柔软的全纱线结构，因此SC和TENG可以很容易地编织成布料，从而连续地收集和存储生物运动能量，这证明了其极大的便利性和广阔的应用前景，如可穿戴，轻便，舒适的连续生物运动。运动能量收集/存储设备和多功能压力感应。
