Various energy harvesting strategies and innovative applications of triboelectric-electromagnetic hybrid nanogenerators

The demand for self-powered technology has driven the development of triboelectric electromagnetic hybrid nanogenerators (TEHG). This review integrates innovative applications of TEHG and explores different environmental energy harvesting strategies. Firstly, the basic theory of TEHG is introduced. Subsequently, the focus will be on introducing innovative applications of TEHG, including self-powered sensors, environmental monitoring systems, wireless sensor networks, and wearable devices. We also discuss different energy harvesting strategies, such as wind energy, vibration energy, blue energy, and bioenergy. Explore energy harvesting strategies through the system and analyze technological advantages and current challenges. Finally, suggestions were put forward to improve the performance of TEHG. Through review and analysis, the aim is to foster innovative ideas on TEHG among researchers, promote continuous innovation, and achieve technological breakthroughs. © 2024 Elsevier B.V.
