中文摘要 海浪是海洋環境中分佈最廣泛的能源,有望為下一代自給自足的海洋勘探和監測儀器提供可再生能源。摩擦納米發電機 (TENG) 技術已顯示出收集海浪能量的潛力。然而,大多數 TENG 設計都面臨著接觸度和能量功率密度相對較低等挑戰,限制它們的實際應用。本文提出了一種固-液界面、管狀摩擦電-電磁混合納米發電機 (TTEHG) 來有效地捕獲波浪能。由於固-液界面與耦合的 TENG 和電磁發生器 (EMG) 設計相結合,TTEHG 具有減少摩擦損失和擴大可收穫波能範圍的特點。即使在 0.2 Hz 的超低工作頻率下,TTEHG 也表現出出色的輸出性能,峰值電流接近 15 mA,能夠為各種功能電子設備供電,例如溫度和濕度傳感器,以展示其在藍色能源回收的實際應用。
英文摘要 Ocean waves, the most widely distributed energy source within the marine environment, promise renewable energy for next-generation self-sufficient ocean exploration and monitoring instrumentation. Triboelectric nanogenerator (TENG) technology has shown the potential in harvesting ocean wave energy. However, most TENG designs suffer from challenges such as relatively low contact intimacy and energy power density, limiting their practical application. This paper proposes a solid–liquid-interfaced, tube-shaped triboelectric–electromagnetic hybrid nanogenerator (TTEHG) to efficiently capture wave energy. Owing to the solid–liquid interface in conjunction with the coupled TENG and the electromagnetic generator (EMG) design, the TTEHG features a reduced frictional loss and broadened range of harvestable wave energy. At a frequency of 1 Hz, the instantaneous power density and current density of the TTEHG are 0.25 mW·cm–3 and 5 mA·cm–3, respectively. Even at an ultra-low operational frequency of 0.2 Hz, the TTEHG exhibits an excellent output performance with a peak current of nearly 15 mA, and is able to power various functional electronic devices, such as temperature and humidity sensors, to monitor the marine environment. The TTEHG was deployed in Sanya Bay, China, to demonstrate its practical application in harsh ocean environments.
