| Abstract | ||||
| The present work discusses the possibility of designing triboelectric nanogenerator (TENG) operated by triboelectrification and magnetic field. The contact-separation and sliding, of polytetrafluoroethylene (PTFE) and polyamide (PA), were operated by the help of magnetic field. The present work showed that the increase of the intensity of magnetic field caused significant voltage increase. That may be form the ability of magnets to induce magnetic field that was responsible for the voltage increase. Besides, the ESC double layer generated from friction supplies the contacting surfaces by an electric field superimposed on the magnetic field offered by the magnets that is responsible for the increase of the voltage difference. It was observed that inserting steel sheet under PA homogeneously distributed the magnetic field on the contact area that caused significant voltage increase. Adhering steel wire in form zigzag into the surface of the steel sheet displayed remarkable voltage increase. Further voltage increase was observed for adhering steel wire in spiral form. | ||||
