| Abstract:This study presented a fully eco-degradable triboelectric nanogenerator （TENG） based on cellulose filter paper， which featured a closed-loop ecological design that integrated renewable substrates with recyclable functional layers to surpass the environmental limitations of conventional devices. The hierarchical composite architecture consisted of polyvinylidene fluoride （PVDF）-modified cellulose paper as the high-efficiency triboelectric layer and copper nanowire-embedded cellulose substrate as the flexible electrode， synergistically achieving an outstanding output voltage of 198 V and power density of 1 038.6 mW/m2. The device successfully droved humidity meters， light-emitting diodes （LEDs）， and calculators. Furthermore， by integrating machine learning algorithms， a self-powered human-machine interface was constructed. Through the recognition of finger movements， it achieved precise control over online gaming. |
