Abstract Among triboelectric nanogenerators (TENGs), liquid‐based TENGs (L‐TENGs) have attracted attention owing to their advantage of using abundant water resources as an energy source. However, electrical performance is lower than that solid–solid (S–S) contact because relatively low charge density. In addition, the ions dissolved in neutralize surface polymer, reducing long‐term stability L‐TENGs. To address this problem, study developed a new strategy not only enhances but also durability L‐TENG. A simple charge‐inducing structure (CIS) designed provide strong reservoir via S‐S contact. Hereby, output during liquid‐solid increased from 38.8 122.7 V OC and 79 253 µA I CC . Moreover, overcomes limitation L‐TENG, which significantly decreases due influence existing enables extension lifespan. Based on structural design, portable aqua ball exercise device with usability presented application for visualizing movements real‐time. Consequently, enhancing through inertia CIS presents commercializing
