The invention belongs to the technical field of flexible sensing, and discloses a multifunctional flexible sensing fiber membrane and a preparation method and application thereof. The multifunctionalflexible sensing fiber membrane includes a flexible base fiber membrane and a hybrid conductive network layer; a flexible polymer material is dissolved in an organic solvent for electrostatic spinning, and an obtained product is placed in the environment at 20-40 DEG C for drying to obtain the flexible base fiber membrane; and the flexible base fiber membrane is placed in a nano-conducting material dispersion liquid for ultraphonic, then the nano-conducting material is combined with the flexible base fiber membrane, and the multifunctional flexible sensing fiber membrane is obtained through washing and drying. The multifunctional flexible sensing fiber membrane has good air permeability and can realize rapid response to multiple stimulating factors such as water/humidity, temperature/nearinfrared light, stress and
