Abstract
The present work aims to develop the efficiency of bidirectional direct current triboelectric nanogenerator (BDC-TENG). Different materials such as aluminium (Al), polyamide (PA) and Kapton films adhered to polymethyl methacrylate (PMMA) cube as moving friction surfaces were tested. They were sliding on the stationary PMMA, poly propylene (PP) and silicon rubber (SR) in order to harvest the generated voltage to be applied as feedback signal of the self-powered sensor used in the electronic skin (e-skin).
 
It was found that among the tested materials used as moving and stationary friction surfaces, Al sliding on SR recorded the highest voltage. Besides, Kapton slid on PMMA showed significant voltage increase with increasing the intensity of the magnetic field when permanent magnets were inserted under the stationary surface. Further voltage increase was observed when the magnets were wrapped by copper coil. In contradiction to that, sliding of Al on PP generated relatively lower values. Further voltage increase observed when the magnets were wrapped by copper coil. It can be concluded that the proposed BDC-TENG can be applied as a self-powered sensor in the application of the e-skin design due to the function of the proposed BDC-TENG that generated bidirectional voltage, where the flow of the direct current in the external circuit in two directions during sliding.
