Description

technical field [0001] The invention belongs to the technical field of micro-nano energy sources and friction nano-generators, and in particular relates to a preparation method of a breathable and highly elastic single-electrode friction nano-generator. Background technique [0002] With the rapid development of micro-nano electronics technology, a wide variety of wearable electronic devices have gradually entered people's daily life. Traditional electromagnetic generators and batteries are difficult to apply in the field of wearable energy due to their rigidity, airtightness, and bulky characteristics. In order to meet people's demand for long-term uninterrupted energy supply for wearable electronic devices, research teams at home and abroad are paying more and more attention to the development of new wearable energy devices. [0003] Human beings will continuously generate various mechanical energy in daily activities, but it is often neglected because it is difficult to ...
