A sliding-friction power generator, a power generation method, and a vector displacement sensor using the sliding-friction power generator. The power generator comprises: a friction layer (100) of which the lower surface is provided with a first conducting layer (200), wherein the first conducting layer (200) is electrically connected to an equal potential (400); and a second conducting layer (300) which is arranged opposite to the upper surface of the friction layer (100). When the upper surface of the friction layer (100) and the lower surface of the second conducting layer (300) slide relatively under the action of an external force, and meanwhile, a friction area is changed in the sliding process, an electrical signal can be output between the first conducting layer (200) and the equal potential (400). In the vector displacement sensor, the friction layer consists of a plurality of friction units. The lower surface of each friction unit is correspondingly provided with a first friction unit which is electrically connected to the equal potential. When the second conducting layer slides on the friction unit, the position, moving direction and moving distance of the second conducting layer can be detected according to the electrical signal output between a first conducting unit and the equal potential without providing power supply for the sensor. |
