The invention belongs to the nano-power generation field and discloses an integrated friction nano-generator. A porous conductive frame which is of a porous structure is formed in a polymer material which is of a porous structure, so that a flexible power generation component can be formed; when an external force acts on the power generation component and makes the power generation component deform, or when the polymer on the upper surface of the power generation component contacts or leaves an external object, charge separation is induced by contact friction between the composite porous conductive frame and the polymer material; separated charges are transferred through the porous conductive frame, as a result, electric potentials of two electrodes, or electric potentials of the upper surface and lower surface of the power generation component are different, and current can be generated; and output power is increased by the porous structures of the porous conductive frame and the polymer material, and therefore, mechanical movement such as shaking, tapping, friction, vibration, and rubbing, can be transformed into electric energy.
