-Abstract
The present work discusses the performance of triboelectric nanogenerator (TENG) based on triboelectrification and magnetic induction. The voltage difference between the surfaces of polytetrafluoroethylene (PTFE) and polyamide (PA) was measured after contact-separation and sliding. PTFE was reinforced by coil of copper wires, while steel sheet fitted by permanent magnets was inserted under PA surface. Voltage difference generated on the surfaces of PTFE and PA was measured after contact-separation and sliding as function of the intensity of the magnetic field.
The present experiments revealed that voltage difference generated from contact-separation and sliding significantly increased withincreasing the intensity of magnetic field. The voltage difference is the resultant of the double charge layers generated on the surfaces of PTFE and PA, the extra electric field generated from coil and the magnetic field.The electric field offered by the coil reinforcing PTFE opposed the magnetic field supplied by the magnets and the electric field generated from friction.Increasing the wire diameter of the coil reinforcing PTFE decreased the voltage difference. Inserting steel sheet wrapped by coil under PA surface did not influence the voltage difference. This is attributed to the opposing action of the electric field offered by the coil wrapping the steel sheet to the magnetic field supplied by the permanent magnets. PTFE reinforced by steel sheet wrapped by coil of 100 turns of 0.1 mm diameter copper wire recorded significant voltage increase. Finally, it is recommended to select properly the arrangement of the construction of the TENG.
