Constructing high-performance and versatile liquid-solid triboelectric nanogenerator with inflatable columnar units

Abstract

Highlights In this paper, a novel and elaborate basic unit structure of inflatable column is proposed. The combination of alternating/direct-current from LS-TENG significantly improves the output performance and energy conversion efficiency. The LS-TENG promises versatile structural designs that can collect energy from multiple application scenarios. The LS-TENG can be used as an efficient and promising energy source for outdoor exploration and ocean rescue. The LS-TENG with inflatable columnar units can be used for self-powered and self-irrigation monitoring system.
