Abstract

The invention provides an electrostatic impulse generator, which comprises a flexible base and power generation units, wherein any two adjacent layers of the base are mutually connected to form a V-shaped or U-shaped sunken structure, the power generation units are arranged in the sunken structures, the two layers on the inner surface of the V-shape or U-shape sunken structure respectively support a friction layer of the corresponding power generation unit, under the action of external force, the size of the opening of the V-shape or U-shape sunken structure of the flexible base is reduced to enable the two friction layers to be contacted with each other so as to generate surface charge transfer, when the external force disappears, the two friction layers of the power generation unit are separated from each other due to the rigidity of the flexible base, and pulse electrical signals are generated on electrode layers. Under the action of periodic external force, the two friction layers of the power generation unit are contacted with each other or separated from each other periodically by the drive of the flexible base, and the pulse electrical signals are generated between the two electrode layers of the power generation units.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to an electrostatic pulse generator and a DC pulse generator that convert naturally occurring mechanical energy such as motion, mechanical vibration, and fluid into electrical energy. Background technique [0002] Today, with the rapid development of highly integrated microelectronic devices, the research on the corresponding energy supply system is relatively lagging behind. In order to meet the needs of miniaturization, portability, and multi-function, the energy of these microelectronic devices comes directly or indirectly from traditional energy supply devices such as batteries. However, due to its own insurmountable limitations, including large volume and weight, limited service life, and potential harm to the environment and human body, it is difficult for batteries to meet the requirements of sustainability, low cost, and environmental protection. Therefore, it is of great s...
