Description
technical field [0001] The invention belongs to the technical field of new nano-energy, and in particular relates to a flexible friction nano-generator, a tire vertical force sensing device and an estimation method. Background technique [0002] The power generation principle of the triboelectric nanogenerator is that when two different materials are in contact with each other under the action of mechanical force, their surfaces will generate positive and negative static charges due to the electric effect of contact; and when the two materials are separated, the contact will generate electricity. The positive and negative charges generated by electricity are then separated, and then an induced potential difference is generated between the electrodes of the two materials and electrons are induced; if the electrodes of the two materials are connected to a load or are in a short circuit state, the above induced potential difference will drive the induction. The electrons flow b...
