Hybrid Inspired Tribolectric Nanogenerator Using Contact Separation Mode
Abstract
The triboelectric nanogenerator (TENG) concept was used to build four contact separation TENG models to harvest mechanical vibration from an aircraft wing on an unmanned air and surface vehicle. The first three models used a hexagonal base structure with cylindrical pegs and solid rectangular bar on top. The last design used a rectangular box structure with a free moving bar to convert mechanical vibration output into electrical power. To simulate the vibrational motion of an unmanned aerial vehicle wing, a linear arm motor was used at various speeds to test each model for harvesting mechanical motion. The experimental results showed that the model that produced the maximum voltage was the attached solid bar design. The free bar structure design allowed the use of two electrodes in one structure. The ability to use two electrodes for one model enhanced the electrical power production. The finite element method analysis showed that the rectangular bar models would produce the best electrical output based on their contact frequency, matching with the experimental results. In conclusion, the results showed that the two rectangular bar TENG models can harvest mechanical vibrational energy and convert it into electrical power. Further research into using additional free bar TENG models together in series would demonstrate the ability to harvest additional voltage to store and use for sensor power.
