In recent years, a free-rotating disk triboelectric nanogenerator (rTENG) has attracted considerable attention as promising energy harvester due to its high output among many (TENG) types. However, the of rTENG is often challenged by air breakdown between electrodes. To overcome this issue, in present work, we have developed based on alcohol-soluble nylon technology (AN-rTENG). Compared conventional nylon-based (CN-rTENG), AN-rTENG significantly suppresses and improves increased capacity...
