This theoretical study by Huang, Lin, and Zheng (2020) highlights the significant potential of structural superlubricity to enhance nanogenerator performance. By achieving near-zero friction, SLNGs demonstrated a three-orders-of-magnitude increase in current densities and output powers compared to conventional designs, alongside improved lifespans and the ability to harvest energy from extremely weak external forces. This suggests that incorporating superlubricity principles could be a key strategy for developing highly efficient and durable energy harvesting solutions for future design projects.
