Abstract

The invention discloses a full-flexible fin driven by a magnetic field and a production method thereof. The full-flexible fin comprises a strip-shaped elastic polymer matrix and a plurality of magnetized magnetic active polymer matrixes embedded in the strip-shaped elastic polymer matrix. The plurality of magnetized magnetic active polymer matrixes are arranged on the strip-shaped elastic polymer matrix in parallel, and the distribution directions of adjacent magnetic domains are completely opposite; and the magnetic active polymer matrixes and the strip-shaped elastic polymer matrix are attached together through the intermolecular force of a material to form the full-flexible fin, and the full-flexible fin is put into an alternating excitation magnetic field to realize periodic flapping motion. The invention discloses a production method of the full-flexible fin. The full-flexible fin is simple, good in stability, high in movement efficiency, excellent in deformation performance, good in movement continuity due to full flexibility, capable of adapting to different complex environments, good in biocompatibility, capable of being applied to a power driving part of an underwater navigation robot and wide in application in the field of soft robots.

Description

technical field [0001] The invention belongs to the technical field of soft robots, and in particular relates to a fully flexible fin driven by a magnetic field and a preparation method thereof. Background technique [0002] Due to its large deformation characteristics, soft robots can adapt to many extreme special scenarios. Therefore, soft robots have broad application prospects in deep sea exploration, biomedicine and other fields. [0003] Organisms are the most perfect flexible machine structures that we know, and drawing inspiration from biological structures for manufacturing has gradually become an important direction in the development of soft robots. Fish can swim freely in the water, which is inseparable from the propulsion of fins. The swing form of simulated fish fins has become an effective means of propulsion for future underwater vehicles. The German FSETO company has studied an underwater navigation robot called BionicFinWave, which can approximately imita...
