Performance Comparison of Copper Mesh and Tape Electrodes Coated with Cellulose Nanocrystals in Triboelectric Nanogenerators

With the advancement of modern technologies and the growing use of wearable electronic devices, the necessity for sustainable energy sources is now stronger than ever. Therefore, developing energy sources capable of harvesting and converting small, wasted energies in the environment is essential. Triboelectric nanogenerators (TENG) have gained attention for converting mechanical energy from everyday movements into electricity. In this research, we developed a triboelectric nanogenerator using nanocellulose-coated copper electrodes. Sawdust-derived nanocellulose was dip-coated on mesh and tape electrodes, and the current and voltage were measured. The average current achieved was ۱.۰۴μA and ۲.۲۰μA for mesh and tape, respectively, while the voltage remained nearly constant in both samples. This indicates that the uniform coating on the tape electrode positions it as a promising option for use in triboelectric nanogenerators.
