The invention discloses a large-area flexible electronic skin slip sensor based on DUS-FBG, and relates to the technical field of flexible electronics. The large-area flexible electronic skin slip sensor comprises an optical fiber flexible skin structure which is formed by packaging a slip sensing array through a flexible packaging material, wherein the slip sense sensing array is formed by grid arrangement and distribution of first DUS-FBGs which are transversely arranged and second DUS-FBGs which are longitudinally arranged, the first DUS-FBGs and the second DUS-FBGs are two grating optical fibers with different central wavelengths, and the array arrangement is that DUS-FBGs with a preset length are arranged at intervals of a preset distance; a tunable laser module used for providing an incident light source for the slip sense sensing array; and a slip sensation sensing module which is used for determining slip sensation generation and ending positions and moments according to the central wavelength shift o
