Underwater bio-robot fish system energy supply device based on piezoelectric material

Abstract

The invention provides an underwater bio-robot fish system energy supply device based on a piezoelectric material. The underwater bio-robot fish system energy supply device based on the piezoelectric material comprises a flexible material substrate, a piezoelectric thin film, a rectifying circuit, a transmitting circuit and an energy storing device, wherein the flexible material substrate comprises a free end and a fixed end, and the fixed end is fixedly arranged on a tail fin or a dorsal fin; the piezoelectric thin film is fixedly arranged on the flexible material substrate; and the transmitting circuit and the energy storing device are implanted or fixedly arranged in the body or head of a fish. According to the underwater bio-robot fish system energy supply device based on the piezoelectric material, disclosed by the invention, the piezoelectric material is deformed by collecting vibration generated by the motion of an organism, and a stimulation device continuously generates electric signals after current is rectified by the rectifying circuit and is transmitted and stored so as to control the nerves of the organism to move. The underwater bio-robot fish system energy supply device disclosed by the invention has the characteristics of light weight, long energy supply continuing time and the like, and can reduce the load in the fish generated due to the weight of an energy supply system so as to realize long-term and long-distance control in a bio-robot fish system.

Description

technical field [0001] The invention relates to a device in the field of bio-robots, in particular to an energy supply device for an underwater bio-robot fish system based on piezoelectric materials. Background technique [0002] Bio-robots start with animal sensory input or neural control to achieve artificial control of animal behavior. In this technology, people use the animal's own motor function by stimulating nerves, muscles, etc. Bio-robotics technology began in the 1990s and is the product of the development and fusion of many technologies. During the long-term evolution process, many organisms have acquired special abilities that cannot be ignored. The advantages of biological robots have led many researchers to turn to the research work of biological robots. Biological robots are more likely to achieve long-distance and complex terrain tasks. Although most of the bio-robot experiments are still under laboratory conditions due to the constraints of complex techn...
