Development of ocean energy is strategic requirement to optimize the energy structure and expand the “blue economic” space, study of a new-type wave energy conversion technique with features of light-weight, wide-frequency, high conversion efficiency and high stability has significant scientific values and application prospects. Triboelectric nanogenerator (TENG), based on the coupling of triboelectric and electrostatic effects, provides a new approach for efficiently capturing wave energy with its unique advantages. This project intends to develop a nod duck-type hybrid electromagnetic-triboelectric nanogenerator (HE-TENG) toward wave energy harvesting, following the two key scientific issues of TENG, relative low current density output and the mismatched impedances between TENG and external loads, through combination of theoretical modelling and experimental methodology, high-energy density HE-TENG unit and network will be realized. This project mainly focuses on: (1) Topology structure design of independent TENG and electromagnetic generator units as well as the charge transfer mechanism; (2) Fabrication of composite film with high dielectric property and regulation study of surface micro / nano architectures; (3) Structure design of the HE-TENG network and regulation study of water wave parameters; (4) Impedance matching design between TENG and electromagnetic generator, power management circuit design and study of high-efficient energy storage. The outcomes of this project will expand the hybrid-effect devices in the application of wave energy harvesting and establish foundation for large-scale blue energy harvesting.
