| 中文摘要 | 電力是穿戴電子、柔性電子的重要罩門。發光也是穿戴科技重要的功能，可用於照明、黑暗中的識別、操作，以及夜間防護等。利用材料表面極化與位移電流而發明的接觸起電奈米發電機，被視為穿戴、柔性電子的能量來源、自發電感測的可行技術。然而，其產生的瞬時電輸出，只能驅動光電元件產生瞬態發光；此外，使光電元件發光所需的能量，也會消耗轉換的能量，限制其他電子設備的使用。 受夜光小菇(Mycena chlorophos)的啟發，我們提出一種可自發光、可擷取身體動能的發電纖維，可用於穿戴能源供應、自發電感測，以及人機界面。此自發光的發電纖維，由不銹鋼纖維作為導電電極，包覆在由磷光材料與接觸起電彈性橡膠的複合材料作為發光與起電層。此自發光、發電纖維可將身體動能轉化為可用電力(5公分的發電纖維可產生15 V開路電壓；500 nA短路電流)。此纖維也可編織成大面積、可拉伸(應變>100%)的發光、發電織物，手掌大小的發電織物可產生約250 V開路電壓、約80 μA短路電流，提供電力給小型電子裝置。暴露在日光下，約5分鐘，可在夜間發出持久的可見光(50 mcd m-2 > 120分鐘)。此外，自發光的發電纖維也可作為自發電的感測纖維(力靈敏度為11.48 V N-1 和119.54 nA N-1 (<1 N)），可用於感測觸摸、手勢、肌肉運動等。最後，與微控制器結合，我們進一步利用此纖維展示系統級智能衣物，包括利用智慧衣操控手機與電腦等。此研究首次將自發光特性與獵能功能同時集成於纖維中，對於穿戴科技有指標性的意義。 |
| 英文摘要 | Wearable/stretchable electronics and e-textiles require power. Meanwhile, luminescence is an important functionality to wearables for illumination, energy saving, identification and manipulation in the dark, and safety during nocturnal activities. Triboelectric nanogenerators (TENGs) are promising power suppliers and self-powered sensors. However, the instant TENG electricity can only produce transient luminescence, and the energy required for luminescence consumes the energy reserved for other electronics. Inspired by bioluminescent Mycena chlorophos, a self-luminescing and energy-harvesting triboelectric fiber (SLEH-TF) is proposed as a wearable energy provider, self-powered sensor, and human–device interface. It comprises a conducting thread clad in an elastic phosphorescent triboelectric composite and can be knitted into a large-area highly stretchable (> 100% strain) textile for sustainably powering gadgets. It can convert biomechanical energy into available electricity (Voc = 15 V and Isc = 500 nA from a 5-cm SLEH-TF; Voc = 250 V and Isc = 80 μA from a palm-sized SLEH-TF textile) and simultaneously emit long-lasting visible light (50 mcd m−2 for > 120 min) after a short exposure to daylight (5 min). Furthermore, SLEH-TF can be used for detecting pressure (with sensitivity of 11.48 V N−1 and 119.54 nA N−1 (<1 N)), touch, and gestures via self-generating electricity. Finally, system-level smart clothes using the newly-designed fibers are presented. The seamless integration of luminescence into energy-harvesting fabrics can advance the development of autonomous wearable accessories. |
