Research on energy harvesting and LED driving prospects of triboelectric nanogenerator

Under the background of world energy crisis and increasingly serious environmental pollution, how to collect and use kinds of mechanical energy in nature has attracted more and more attention. TENG can be used to collect wind energy, ocean energy, vibration energy and other kinds of energy. In this study, we have fabricated a TENG for collecting impact energy, it consists of two independent generating units. In addition, this paper also designs a power management circuit, the circuit is mainly composed of rectifying part and voltage stabilizing part, the rectifying part is stacked by rectifying bridges, the AC signal generated by the TENG is rectified into a pulsating DC signal, after capacitance filtering, the voltage stabilizing part uses a voltage stabilizing diode to convert the output voltage into a stable DC voltage. It has been tested by experiment, when generating unit is working, the voltage can be stabilized at 3.7V by single tube circuit.
