A hybrid nanogenerator integrates both triboelectric and piezoelectric components into a single device. By doing so, it can harness energy from different types of mechanical inputs more efficiently. When the hybrid nanogenerator is subjected to mechanical motion, both triboelectric and piezoelectric effects are activated. For example, when pressing or sliding motions occur, the triboelectric layers produce a charge due to contact and separation, while the piezoelectric material generates a charge from the mechanical stress applied. The combined effect can produce higher electrical output and improve the efficiency of energy harvesting from a broader range of mechanical motions. In this paper, the novel structure of hybrid triboelectric and piezoelectric nano-generators have been merged to harvest abundant mechanical energy. Ecoflex and PVDF-based hybrid nanogenerator have been proposed to harvest mechanical energy. While Ecoflex synthesized with 0.5 % hexachlorofullerene (C60Cl6) is used for the triboelectric layer in the TENG part, 3wt% polymethyl methacrylate (PMMA) integrated with polyvinylidene fluoride (PVDF) matrix is utilized as a dielectric medium in piezoelectric part of the nanogenerator. Efficient hybrid nanogenerator structures were selected and appropriate power converters were used. The hybrid NG’s performance in generating electrical microenergy was demonstrated experimentally. Keywords: hybrid nanogenerator, triboelectric nanogenerator, piezoelectric nanogenerator, mechanical energy harvesting, dielectric medium, power converter circuit.
