The invention relates to a flexible bionic sensor, a bionic whisker array unit and an underwater vehicle. The flexible bionic sensor comprises a flexible corrugated sleeve, a shell, at least four friction nanometer power generation units, a collision unit and a beard shaft. A sealing cavity is formed in the flexible corrugated sleeve, and one end of the sealing cavity is a deformable corrugated part; an opening is formed in one side of the shell, the shell is connected into the sealing cavity, and the opening faces the corrugated part; the friction nanometer power generation units are uniformly connected in the circumferential direction of the inner wall of the shell; the collision unit comprises an elastic body and a collision body. According to the underwater sensing unit, by simulating the structure of seal beards and integrating the triboelectric nano-generator in a contact separation mode, tiny flow field interference is converted into electric signals, so that various near-field information including flow velocity, attack angle and wake information of a three-dimensional flow field can be obtained at the same time, and meanwhile, the defects of an existing underwater sensing unit are overcome; the method has the advantages of short response time, high sensitivity, high signal-to-noise ratio, no environmental limitation and the like.
