JBNU Researchers Propose Hierarchical Porous Copper Nanosheet-Based Triboelectric Nanogenerators

The proposed innovation demonstrates multifunctionality in terms of efficient energy harvesting, EMI shielding, and Joule heating  

JEONBUK-DO, South Korea, Jan. 8, 2026 /PRNewswire/ -- In recent years, two-dimensional (2D) single-crystalline metal nanosheets have emerged as a promising next-generation platform for self-powered electronics. However, their potential for triboelectric nanogenerators (TENGs)—a promising energy-harvesting technology—remains largely untapped, mainly due to their low current output and limited durability.
