摘要

In the modern age of the Internet of Things, nanogenerators have advanced due to their stability, portability, and sustainability. This study focuses on high-performance wood-based nanogenerators. Natural wood possesses a unique three-dimensional microstructure with hierarchical, interconnected channels aligned along its growth direction. This porous, highly oriented structure of wood was fully studied and maintained during the whole delignification process. Calcium chloride and silver nanowires were used as backfilling agents in the delignified wood, enhancing its electrical conductivity. The resulting conductive wood served as both the friction layer and electrode, forming a single-electrode triboelectric nanogenerator with excellent electrical output performance. Our findings highlight the potential of multifunctional wood as an eco-friendly, sustainable energy source, contributing to the future of smart cities.
