Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to a friction nanogenerator. Background technique [0002] Harvesting and converting energy through nanotechnology plays a key role in the design and fabrication of self-generating and self-driving nanosystem devices. Since Professor Wang Zhonglin from the Georgia Institute of Technology invented the triboelectric nanogenerator, people have successively developed triboelectric nanogenerators based on different materials and structures. The generator mainly utilizes the difference in the triboelectrode sequence of the material to realize electron transfer in the process of friction contact, and drive the free electron flow to move through the potential difference. Nanogenerators can collect energy from the surrounding environment to generate electricity, convert mechanical energy into electrical energy, and drive electronic devices to operate. Compared with traditional electromagnetic...
