Abstract In the last decades, numerous mechanical energy sources have been utilized as primary energies to produce electricity by using different energy harvesting technologies, such as electromagnetic, and piezoelectric technologies. Among these mechanical energy sources, fluid flow energy, defined by water flow and airflow energies, is one of the most important and wide-used renewable energy sources, which is available in nature under the form of raindrops, streams, ocean waves and wind energies. Since the first introduced in 2012 by Wang’s research group, the triboelectric nanogenerator (TENG) has become one of the most vital innovations in harvesting energy technologies. Many TENGs devices have been developed and demonstrated its potential in harvesting fluid flow energy. Here, a review of the fluid-based TENG (F-TENG) is presented, including water-based and air-based, with the fundamental theories, basic mode of operations, its current designs, and application. The development of F-TENG is demonstrated via the divers of design structure, high potential application for power generation, and high sensitivity for self-powered sensing systems. F-TENG shows promising potential for large-scale application, and hybrid with other energy harvesting technologies. Besides, this article also considers the recent difficulties which reduce the performance of F-TENG, then presents the ways for improving their efficiencies. Finally, this study provides a point of view based on the facing challenge and future development trend of the F-TENG.

1 Introduction Nowadays, excessive fossil fuel consumption leads to a rapid depletion of their reserves and has a significant adverse impact on the environment and becomes one of the biggest challenges the world facing [1]. Therefore, searching for clean and renewable energy is necessary for sustainable development. As one of the most important renewable energy sources, ambient mechanical energy from the environment, including vibrations, walking, human motions, raindrops, flowing water, ocean waves, wind [2], can be used to produce electricity via energy harvesting technologies * Kyoung‑Kwan K.
