| 中文摘要 | 隨著環境污染日益嚴重以及潛在的能源危機，人類迫切需要可持續發展的低污染能源，雖已擁有太陽能、風能、水利等傳統發電設備，但因其造價昂貴及佔地面積大，易受到氣候和地域限制，且無法隨時、大面積的收集自然能源，造成其效率及成本大大受到限制。在近幾年被提出的「摩擦奈米發電機」，具有廣泛材料可用性及可收集低頻能量等特性，可以解決傳統發電設備無法大量製造、低頻運作、攜帶不便甚至是電池需頻繁更換的問題。 過去我們選擇使用活性碳作為可拉伸摩擦奈米發電機之導電材料，因為活性碳相較昂貴的金屬、金屬納米材料便宜，易取得且具有優異化學穩定性，良好的耐熱性，高導電率以及高表面積等特性。但是在活性碳製程中，主要是由煤或石油等材料加工而成，過程中會產生許多汙染，因此考量現今的能源危機以及日漸惡化的環境，我們在本次研究中提出了此款以咖啡渣取代傳統電極材料的研究。 全球巨大的咖啡消費量（每天20億杯，每年浪費600萬噸）使咖啡渣成為城市典型的廢物之一，若是可以將其回收利用，並以創新的方式再利用對環境保護和永續能源的開發都具極大意義；由於咖啡巨大的消耗量及高碳水化合物含量的特性讓咖啡渣被視為電極材料的新興選擇，環保與永續的前提下也因此成為本次研究的主題，以下我們將介紹我們本次研究--以咖啡渣為電極的可高度拉伸，柔性的人體動能擷取元件與自驅動生理感測及智慧介面。 |
| 英文摘要 | Maximizing resource recycling and finding renewable energy sources are important for a sustainable environment considering the development and consumption of electronic products with the advancement of the internet of things and artificial intelligence technologies. Herein, an economic and environment-friendly triboelectric nanogenerator derived from the discarded coffee ground waste (CG-TENG) is developed to serve as a light-weight and shape-adaptive energy source and self-powered sensitive sensor (CG-TENG sensor). The coffee ground, embedded into the silicone rubber elastomer, is first used as the metal-free electrode feedstock to minimize waste generation. Based on the triboelectrification and electrostatic induction, the shape-adaptive CG-TENG, as wearable power, is capable of harvesting surrounding energy from human motions and extreme deformations, exhibiting excellent stretchability and mechanical durability. The generated electricity can be stored in the conductive coffee ground-derived capacitors to drive portable electronics, which is beneficial for building completely green power systems using coffee waste. Furthermore, the self-powered CG-TENG sensor with optimized structure endows its ultra-high sensitivity for sensing human physiological signals, monitoring motions, emulating gestures, as well as for developing smart tactile epidermal controller and intelligent vending coaster, paving the way for building large-scale energy-efficient artificial sensors and eco-environmental wearable electronics towards humanoid robotics and human-machine interfaces. |
