Description
technical field [0001] The invention belongs to the technical field of friction nanometer generators, and relates to a friction nanometer generator based on a micro-channel and a power generation method. Background technique [0002] In recent decades, the global energy crisis has become increasingly prominent, and the current fossil fuel resources have been unable to meet human needs for energy. In addition, the environmental problems brought about by the burning of fossil fuels are also endangering human health, which makes people have to consider new ways of production capacity. In recent years, the way of production capacity has developed in a multi-polar direction, not relying solely on fossil energy to provide energy. Various forms of power generation such as solar energy, wind energy, tidal current energy, and mechanical energy are used in daily life production. Mechanical energy is a kind of energy that is relatively easy to obtain in life. It exists in many forms,...
