A flexible and transparent graphene based triboelectric nanogenerator

This paper presents a new high-output, flexible and transparent nanogenerator using CVD grown graphene as one of the friction layer. Graphene on copper is transferred onto PET by wet transfer method, which makes this graphene based TENG have electrical conductivity and high optical transmittance. We have fabricated fluorocarbon plasma treated thin layer of PDMS structure as another friction layer to improve the output performance of nanogenerator. Using this Graphene-based TENG, maximum output voltage 650 V and current 12μA is achieved at 4.3 Hz frequency. As a power source 50 commercial blue LEDs is lighted up. It is low cost, simple and robust approach for harvesting ambient vibration energy.
