| 中文摘要 | 近年被提出的新型能源收集技術「摩擦奈米發電機」被視為一種能夠作為隨身能源的供給系統，不同於傳統發電機會受到環境限制的發電方式，摩擦奈米發電機可以利用摩擦起電的方式將機械能轉為電能，被視為是一種可以有效收集周遭能源隨時隨地發電並實現自驅動感測器的技術，而拓樸材料(topological insulator；TI)作為近來相當受到期待的新興材料，具有獨特的表面導電內部絕緣特性，有助於表面電荷的移轉；本次研究我們利用快速且較低成本的溶液法合成Bi2Te3 奈米片，透過KPFM等儀器分析與量測探討其電子特性，為Bi2Te3 奈米片形成之TI 薄膜在摩擦電序列上成功定序，並將其導入摩擦奈米發電機，製作成本次之TI-TENG，得益於其良好的表面電荷特性，TI-TENG 展現出相當不錯的輸出功率及能量收集能力，可以驅動小型穿戴式電子產品運作。此外，利用其自發電的特性，更可以將TI-TENG作為自供電的主動式感測器，且具備抗干擾能力；實際我們也將TI-TENG感測器與人機介面結合，成功實現了系統級的應用，包含遊戲控制器及無線智慧音樂播放器，成功搭起了拓樸絕緣奈米材料與摩擦電領域及穿戴式電子領域的橋樑。 |
| 英文摘要 | Reliable energy modules and higher-sensitivity, higher-density, lower-powered systems are constantly required for the development of wearable electronics. As an emerging technology, triboelectric nanogenerators (TENGs) have been potentially guiding the landscape of sustainable power units and energy-efficient sensors. However, the existing triboelectric series is primarily populated by polymers and rubber, limiting triboelectric sensing plasticity to some extent owing to their stiff surface electronic structures. Therefore, new triboelectric materials that are fundamentally different in terms of physical properties and electronic structure are urgently required to achieve energy-efficient, reliable, technologically-simple, and scalable sensory systems. To enrich the current triboelectric group, we explore the triboelectric properties of the topological insulator (TI) nanofilm by Kelvin probe force microscopy (KPFM) and reveal its relatively positive electrification charging performance. Both the larger surface potential difference and the conductive surface states of the nanofilm synergistically improve the charge transfer behavior between the selected triboelectric media, endowing the TI-based TENG (TI-TENG) with considerable output performance. Besides serving as a wearable power source, the ultra-compact TI-TENG array demonstrates smart system-level sensing capabilities, including precise monitoring of dynamic objects and real-time signal control at the human-machine interface. This work fills the blank between topological quantum matters and TENGs, and, more importantly, exploits the significant potential of TI nanofilms for self-powered flexible/wearable electronics and scalable sensing technologies. |
