Triboelectric nanogenerator with deceleration strip for harvesting vibration energy

Abstract

To achieve the peaking of carbon emission and carbon neutrality, optimizing the energy structure and accelerating the energy transformation has become an inevitable choice to tackle global climate change and promote sustainable development. The search for sustainable clean energy is urgently needed. In this paper, a triboelectric nanogenerator with deceleration strip (DS-TENG) is proposed to harvest the vibration energy in the environment. The DS-TENG comprises a displacement platform, a base plate, and six springs. The experimental data show that the output performance of DS-TENG: the open-circuit voltage 309 V, short-circuit current 16.6 μA, and transferred charge is 96.6 nC. Meanwhile, the DS-TENG can power the LED board with “20” pattern by harvesting energy from human movement. It can be seen the DS-TENG can harvest energy from low-frequency mechanical energy in the environment. Simultaneously the DS-TENG shows its potential application value in the field of energy collection and expands the application space of TENG in the human living environment.
