A Review of Fluid Energy Converters Based on Triboelectric Nanogenerators: Performance Analysis from Energy Conversion

Abstract

In recent years, the development of the Internet of Things has challenged traditional energy supply methods. Suddenly rising maintenance costs and serious environmental pollution have led to great concern over energy supply methods such as wired transmission and batteries. Fluid energy is a kind of clean energy widely existing in nature, which can effectively reduce costs and environmental pollution. In the field of collecting fluid energy, fluid energy converters based on triboelectric nanogenerators (FEC-TENGs) have always been a research hotspot. This paper reviews the latest research progress of FEC-TENGs. Firstly, the basic working principle and working mode of FEC-TENGs are introduced. Then, the theoretical process and application examples of converting fluid energy into electrical energy or electrical signals are analyzed in detail. According to the calculation process of energy conversion efficiency and the performance evaluation parameters, the structural design, performance output, and application fields of FEC-TENGs are summarized. Finally, this paper points out the challenges and shortcomings of the current FEC-TENGs and provides our views on the future development of this field.
