Abstract
The invention provides an internal multi-degree-of-freedom flag type friction nanometer generator and a self-powered sensor. The internal multi-degree-of-freedom flag type friction nano-generator comprises a polytetrafluoroethylene film with two polished surfaces; the surface, facing the polytetrafluoroethylene film, of the polyethylene glycol terephthalate film is uniformly coated with conductive ink; the polytetrafluoroethylene film is fixedly connected with the edges of the polyethylene glycol terephthalate films which are arranged up and down; when the device is subjected to external vibration, the middle of the polytetrafluoroethylene film is alternately contacted and separated from the polyethylene glycol terephthalate films which are arranged up and down, so that the films on the two sides of the polyethylene glycol terephthalate have different potential differences at different moments, and after the device is externally connected with an external circuit, current can be generated under the condition of stable air inlet. The energy density of power generation of the flag type friction nanometer generator can be improved, and a single small flag type friction nanometer generator can also have large energy efficiency output.
Description
technical field [0001] The invention relates to the technical field of self-powered energy, in particular, to an internal multi-degree-of-freedom flag-type triboelectric nanogenerator and a self-powered energy sensor. Background technique [0002] With the rapid development of modern society and the arrival of the era of artificial intelligence, people's daily life has become more and more inseparable from various electronic devices. Whether it is personal miniaturized electronic equipment or industrial production equipment, it is inseparable from the continuous supply of electric energy. The problem of energy shortage has become increasingly serious, and it is urgent to develop machinery and equipment that can utilize renewable energy to alleviate the problems caused by the shortage of traditional energy. Whether it is wind energy, ocean energy or sound energy and other renewable energy sources, they all have large reserves, wide distribution, no pollution, and good utiliz...
