STRUCTURAL SUPER-SLIP BASED MICRO-GENERATOR AND GENERATOR SET

WIPO Patent Application WO/2023/029305

A1

A structural super-slip based micro-generator and a generator set, the micro-generator comprising a sliding part, an insulating dielectric layer, and an electrode. The insulating dielectric layer is a dielectric layer made of a single material; the sliding part is slidable relative to the insulating dielectric layer; a lower surface of the sliding part and an upper surface of the insulating dielectric layer form a structural super-slip contact state; the sliding part slides reciprocally on the upper surface of the insulating dielectric layer between the area corresponding to the electrode and the area not corresponding to the electrode; the sliding part and the insulating dielectric layer are electrically charged by contact or by induction of injected charges; when the sliding part and the insulating dielectric layer slide relative to each other, charges are induced in the electrode. Because the two surfaces in sliding contact form a structural super-slip contact state, no wear occurs during sliding, thereby prolonging the service life. The actual area of contact between the two surfaces in sliding contact is close to the apparent area of contact, and the actual area of contact is larger. The surface charge density is increased, such that the output performance of the generator is improved.
