中文摘要 海浪能是一種很有前景的清潔再生能源，可以緩解全球能源危機和環境問題。 在此，開發了一種基於引導液體的各向同性摩擦電電磁混合奈米發電機（iTEHG），用於高效、可持續地收集全向海洋波浪能。 全封閉式iTEHG 基於摩擦奈米發電機(TENG) 和電磁發電機(EMG)，採用獨特的同心圓電極對的結構設計，該電極對建立在傾斜的衛星天線啟發板上，用於重力引導液體運動。 新設計的海浪採集器解決了主流固-固界面TENG的磨損和接觸不足問題，延長了裝置壽命，與其他固-液界面TENG相比，提高了液體的可控性。 這會產生 7.25 µW·cm–3 和 4.85 µA·cm–3 的即時功率和電流密度，並具有無差異的 360° 覆蓋範圍。 iTEHG 可將 0.1 F 超級電容器充電至 3.1 V，並連續驅動無線溫度計超過 26 分鐘。 它在真實海洋環境中的實際應用中表現出卓越的性能，透過在中國三亞灣持續驅動 320 個高亮度 LED，即使在海洋活動安靜的時期也能證明這一點。 所提出的設計預計將為未來的藍色能量收集帶來廣闊的前景，並激發自給自足的海洋感測器的開發。
英文摘要 Ocean wave energy is a promising clean and renewable energy source to mitigate the global energy crisis and environmental issues. Here, a guided-liquid-based isotropic triboelectric–electromagnetic-hybrid nanogenerator (iTEHG) is developed for efficient and sustainable harvesting of omnidirectional ocean wave energy. The fully-enclosed iTEHG is based on a triboelectric nanogenerator (TENG) and electromagnetic generator (EMG), with the structure design of a unique concentric circular electrode pair built on a tilted satellite-dish-inspired plate for gravity-guided motion of the liquid. The newly-designed ocean wave harvester solves the wear and insufficient contact problems of mainstream solid–solid-interfaced TENGs, prolonging the device lifetime, and improves controllability of liquid compared with other solid–liquid-interfaced TENGs. This produces immediate power and current densities of 7.25 µW·cm–3 and 4.85 µA·cm–3 with undifferentiated 360° coverage. The iTEHG can charge a 0.1 F supercapacitor to 3.1 V and continuously drive a wireless thermometer for over 26 min. It exhibits superior performance for practical applications in real ocean environments, proven by continuously driving 320 high luminosity LEDs in Sanya Bay, China, even during quiet periods of ocean activity. The proposed design is expected to have a broad prospect for future blue energy harvesting and inspire development of self-sufficient ocean sensors.
