- Abstract:
-
The large-scale deployment of distributed sensor nodes in the Internet of Things created an urgent demand for self-powering technologies. Currently, sensors were mostly powered by batteries, which faced problems such as environmental pollution and limited endurance. However, the triboelectric nanogenerator (TENG), which could convert ambient mechanical energy into electricity, provided an ideal solution. This paper combined bionics and TENG technology. It systematically analyzed the advantages of TENG in harvesting energy from natural fluids. Based on different fluid characteristics, it summarized the applicable structures and performance features. First, the characteristics of natural fluids and the working principle of TENG were outlined. Then, the form characteristics of wave energy, water flow energy, and wind energy, as well as the advantages of bionic TENG, were clarified. In the field of wave energy harvesting, bionic TENG could better adapt to complex wave conditions and achieve multi-directional wave energy harvesting. In water flow energy harvesting, bionic TENG could effectively eliminate the lock-in effect and achieve start-up at low flow velocities. It thus compensated for the low efficiency of traditional methods under low flow conditions. In wind energy harvesting, bionic TENG, with the aid of bionic airfoils, achieved start-up at lower wind speeds and promoted omnidirectional wind energy collection. This paper also discussed existing structural problems and looked forward to future developments. In addition, it constructed a "biological prototype - structure - performance" correlation framework. This framework provided a reference for TENG structural optimization, promoted its large-scale application in scenarios such as the marine Internet of Things and smart agriculture, and contributed to the global energy transition
