Magnetic control negative pressure adhesion device simulating octopus tentacles and preparation method of magnetic control negative pressure adhesion device

The invention discloses a magnetic control negative pressure adhesion device simulating octopus tentacles and a preparation method of the magnetic control negative pressure adhesion device, and relates to the technical field of intelligent devices of bionic structures. The device comprises a shell; the tentacle main body is conical, and the large-diameter end of the tentacle main body is mounted on the shell; the suction cup is installed on the side wall of the tentacle main body, and the suction cup is an improved structural part made of a magnetic response polymer; the magnetic control assembly is installed in the tentacle main body, and the magnetic control assembly is used for controlling the overall deformation quantity of the suction cup, so that the suction cup is driven to generate different negative pressures; the stay wire driver is mounted in the tentacle main body, and the stay wire driver is used for driving the tentacle main body to stretch and roll. According to the magnetic control negative pr
