Bionic sebaceous gland and artificial skin

The invention provides a bionic sebaceous gland and artificial skin, the bionic sebaceous gland and artificial skin comprise a shell and hair fibers, a conveying pipeline is arranged in the shell, the conveying pipeline is filled with the hair fibers, and gaps formed by the hair fibers in the conveying pipeline are filled with lubricating oil; gaps formed by hair fibers in the conveying pipeline are gradually reduced and then gradually increased in the conveying flow direction; the bottom of the shell is of a permeation structure and used for sucking lubricating oil from the environment. A plurality of through holes are formed in the top of the shell and used for discharging lubricating oil to the outside. Through the gaps between the inner wall of the conveying pipeline and the hair fibers and the gaps between the adjacent hair fibers, lubricating oil can be pulled to be conveyed in the reverse gravity direction along the conveying flow. Meanwhile, due to the fact that the scaly outer skin of the hair fiber
