Energy harvester devices have garnered enormous attention in various technologies, such as wearing and portable devices. The current study aims to design and fabricate tribo/piezoelectric hybrid nanogenerators with electrodes made of Aluminum and Copper and Zinc Oxide nanostructures composite embedded in the PDMS. According to the morphology studies, Zinc Oxide nanosheets grew uniformly in the (103) crystal direction on the Aluminum substrate. In contrast, the nanorods that grew on the Copper substrate were disorderly with a large angle to the surface. The results indicate that the 1000 rpm deposition PDMS layer sample with Aluminum electrodes and Zinc Oxide nanosheets generated the highest voltage and current equal to 120 V and 24 µA, respectively. Both Copper and Aluminum electrodes coupled with ZnO nanosheets nanogenerator had the lowest voltage, current, and power generation. The hybrid nanogenerator with two aluminum electrodes and Zinc Oxide nanosheets generated the highest power equal to 0.97 Wm-2. According to the obtained results from the characterization of hybrid piezo/triboelectric nanogenerators, Aluminum electrodes with Zinc Oxide nanosheets embedded in PDMS exhibited better performance, hence a suitable option for harvesting mechanical energy for self-charging devices.
