Abstract
The textile triboelectric nanogenerator (TENG) has emerged as a robust energy harvesting technology for portable power systems and wearable electronics applications. However, the susceptibility of the textile material to ambient humidity and temperature profoundly influences the performance of TENG, creating bottlenecks in the development of textile-based TENG devices. This study investigates the impact of temperature (20–70 °C) and humidity (20–90%) on textile-based TENG performance in vertical and sliding contact separation modes. The results show a significant impact of both parameters, reducing voltage and current by 89 and 84%, respectively, as the relative humidity increases. The moisture present in the atmosphere has shown a negative effect on the charge transfer, demonstrating a gradual reduction in the transferred charge with the humidity. Similar results were observed when increasing the temperature from 20 to 70 °C; the voltage and current were reduced by 79 and 64%, respectively. When examining the impact of temperature and humidity, it becomes evident that humidity exerts a more pronounced effect, primarily attributable to the interaction of moisture with textile fibers. Studying the effects of humidity and temperature on textile-based triboelectric nanogenerators offers valuable insights into optimizing their performance and enhancing their reliability for various practical applications.
