Abstract

The invention relates to a biomimetic fish, in particular to a hydrogel biomimetic fish based on electrosensitive driving, comprising a fish body, a microcontroller unit, a power source, an external wire and an internal wire. The microcontroller unit controls magnitudes of voltages running through the internal and external wires when the power source is in different environments through the intelligent control algorithms, such as a neural network and fuzzy control; an electric field around the fish body can be controlled underwater through the microcontroller unit to vary; electrosensitive hydrogel in electrolyte solution may vary in size or shape under electric field stimulation; such variation is reversible; the fish body moves like an eel; flexible propulsion in water is achieved. The hydrogel biomimetic fish based on electrosensitive driving is simple in structure; the electrosensitive hydrogel is used as a fish body material, so that controlling movement is easy; the hydrogel material can provide acoustic stealth; the body of the hydrogel biomimetic fish based on electrosensitive driving is formed in one step by 3D printing, and quick small-lot production is available.

Description

technical field [0001] The invention relates to a bionic fish, in particular to a hydrogel bionic fish driven by electric sensitivity. Background technique [0002] With the development of human civilization, the land resources that can be exploited and utilized are decreasing and depleting day by day, and more and more scientists are turning their attention to the ocean. Underwater robots with the functions of ocean survey, ocean exploration, ocean salvage, submarine pipeline detection, and underwater detection and tracking have become important tools for ocean exploration, ocean development, and ocean defense. [0003] Traditional propeller-propelled underwater robots have disadvantages such as bulky structure, low reliability, loud noise, and poor anti-interference ability. In recent years, it has become a new goal pursued by researchers to imitate the swimming propulsion mode of fish and develop high-efficiency, low-noise, flexible and maneuverable bionic robot fish.
