▎ 摘　　要

This paper presents a new high-output, flexible and transparent nanogenerator using chemical vapor deposition grown graphene as one of the friction layer. Graphene on copper is transferred onto polyethylene terephthalate by wet transfer method makes graphene-based triboelectric nanogenerator (TENG) have electrical conductivity and high optical transmittance. We have fabricated plasma treated thin layer of polydimethylsiloxane structure as another layer to improve the output performance of nanogenerator. Using this graphene-based TENG, maximum output voltage 650 V and current 12 mu A is achieved at 4.3 Hz frequency. As a power source, LCD and 50 commercial blue light-emitting diodes are lighted up. It is low cost, simple, and robust approach for harvesting ambient vibration energy.
