technical field [0001] The invention relates to the technical field of power generation, in particular to a calculation method, device and system for outputting electric energy of a friction generator. Background technique [0002] As we all know, when objects rub against each other, one side will be negatively charged and the other side will be positively charged. This kind of electricity generated by friction between objects is called triboelectricity. Triboelectricity is one of the most common phenomena in nature, and the generation conditions of triboelectricity are very wide. At present, triboelectric generators have been successfully prepared using the principles of triboelectrification and electrostatic induction, which can convert mechanical energy into electrical energy.
