Abstract

The present work discusses the effect of magnetic field on the voltage output of a triboelectric nanogenerator (TENG) based on triboelectrification and magnetic field. One of the major factors influencing the performance of the TENG is the position of the permanent magnets relative to the triboelectrified area. In the present study, experiments were carried out to investigate the proper places of the permanent magnets relative to the tested area. The voltage difference between the surfaces of polytetrafluoroethylene (PTFE) and rabbit fur was measured after contact-separation and sliding.
 
When the magnets were placed on the top of the PTFE film, the strength of magnetic field is concentrated above the PTFE film, while the presence of the steel sheet under PTFE film reduced the magnetic field strength because steel shield attracts and redirects the field lines out of the sliding area. It was found that the increase of magnetic fields caused significant voltage increase. Besides, voltage displayed lower values by contact-separation than that measured for sliding. When the magnets were placed under the PTFE film, voltage decreased for contact and separation. The best results were observed for placing magnets above and under PTFE film, where higher voltage values were measured. Finally, replacing the steel sheet by PMMA generated significant voltage increase. Based on that observation, it is recommended to apply nonmagnetic materials in the design of hybrid electromagnetic triboelectric nanogenerator.
