Description

technical field [0001] The invention relates to an energy-storage frictional nanometer generator that efficiently captures intermittent motion energy, and belongs to the field of energy collection. Background technique [0002] With people's excessive dependence on fossil fuels, the gradual reduction of traditional energy sources and the search for renewable energy sources have become the main focus of people. Harvesting random and irregular intermittent mechanical energy from the environment is the best choice to alleviate the current energy crisis. [0003] Triboelectric nanogenerators are being investigated by researchers all over the world due to their potential to recycle mechanical energy from their surroundings. At present, the sliding mode and the contact-separation mode are the modes used by most triboelectric nanogenerators when harvesting energy, but both forms of triboelectric nanogenerators require continuous excitation to achieve energy harvesting. However, m...
