Multi-pulse triboelectric nanogenerator based on laser-induced graphene microgap corona discharge

discharge,pulse,macrogap

Purpose/Aim

Triboelectric nanogenerators have received much attention as one of the best energy options in the IOT era, capable of converting various forms of mechanical energy into electrical energy. However, the output power of TENG is low, thus limiting the scope of putting it into practical applications. It has been found that the introduction of corona discharge can increase the output power of TENG, but there is relatively little research on the factors influencing the corona discharge to increase the output power of TENG based on the current study.

Experimental/Modeling methods

We propose a laser-induced graphene-type electrode multi-pulse nano-friction generator (LIG-TENG), which uses the LIG-type electrode and the integration of TENG and microgap to control the negative corona discharge, thus achieving the output power increase

Results/discussion

The experimental results show that Voc, Isc, and Qsc are increased by 124%,432%,857% respectively.

Conclusions

.In this paper, we demonstrate a multi-pulse Triboelectric nanogenerator based on laser-induced graphene microgap corona discharge, resulting in a significant increase in output power, especially Voc, Isc, and Qsc by 124%, 432%, and 857%, respectively .
