| 中文摘要 | 摩擦奈米發電機 (TENG) 在新能源展現潛力。然而，它們的工作需要接觸和分離，容易使元件缺陷。在此，提出了第一種可拉伸非接觸式奈米發電機，使用拓樸絕緣體奈米複合塗層（摩擦電層）和類石墨織物（摩擦電荷儲存器）。該設計涵蓋摩擦電荷的捕獲、傳輸和存儲，從而提高了裝置性能（452 V、1.96 mA m−2 和 179 mW m−2）並延長了摩擦電荷保留時間（5000 分鐘）。在非接觸操作期間，對於 0.1、0.5 和 1 的間隔距離，輸出保持在 382 V (318 µA m−2)、123 V (59 µA m−2) 和 94 V (23 µA m−2)。此外，它還具有出色的拉伸性（>100% 應變）。值得注意的是，其在非接觸式操作和機械自由度方面的性能超過了先前的報告，從而實現非接觸式力學能量收集和可變形自供電接近感測。最後，我們展示其作為系統級應用非接觸式介面應用。 |
| 英文摘要 | Triboelectric nanogenerators (TENGs) have revealed fascinating potential in multifaceted wearables. However, their reliance on physical contact and separation from human bodies presents drawbacks for efficient energy collection, especially over large areas. Herein, the first stretchable non-contact TENG textile is proposed using a topological insulator nanocomposite coating (triboelectric layer) and a graphite-like fabric (tribo-charges reservoir). This design encompasses the capture, transporting, and storage of tribo-charges, leading to enhanced device performance (452 V, 1.96 mA m−2, and 179 mW m−2) and prolonged tribo-charges retention time (5000 min). During non-contact operation, the output remained at 382 V (318 µA m−2), 123 V (59 µA m−2), and 94 V (23 µA m−2) for separation distances of 0.1, 0.5, and 1 cm, respectively. Additionally, it exhibits excellent stretchability (>100% strain). Notably, its performance during non-contact operation and mechanical freedom surpasses those of previous reports, enabling both wearable non-contact biomechanical energy harvesting and deformable self-powered proximity sensing. Its applicability is comprehensively examined for non-contact harvesting of body-motion energy in garments and driving electronics. Finally, its application as a self-powered touchless interface for system-level applications is demonstrated. These results provide new directions for developing non-contact biomechanical energy harvesting and sensing, enabling advancements in autonomous wearables and Metaverse applications. |
