Abstract

The invention discloses a flexible bionic side line sensor of an integrated IPMC sensing structure. The flexible bionic side line sensor comprises an integrated IPMC sensing structure, a flexible upper base film, a flexible lower base film, a fixed circular truncated cone and a sensing top, wherein the bottom of the integrated IPMC sensing structure is attached between the flexible upper base filmand the flexible lower base film in an interlayer structure mode, and the upper part and the lower part of a vertical cilium-shaped structure of the integrated IPMC sensing structure are coated and connected by the sensing top, and a center through hole of the fixed circular truncated cone penetrates to the bottom in a sleeving mode, and is fixedly connected with the surface of a bottom sensing unit of the integrated IPMC sensing structure. According to the invention, the intelligent material IPMC with excellent comprehensive performance is used as a sensing structure, the process is simple and feasible, the sensing of the flow velocity and the flow direction can be realized, the sensing structure can be conveniently and randomly attached to underwater vehicles with surfaces in differentshapes, and the adaptability and the practicability to marine equipment with surfaces in complex shapes are enhanced.

Description

technical field [0001] The invention relates to the field of underwater sensors, in particular to a flexible bionic lateral line sensor with an integrated IPMC sensing structure. Background technique [0002] In recent years, with the intensification of domestic and foreign efforts to manage the ocean, there is an urgent need to develop new marine equipment for both military and civilian purposes. Underwater bionic robots have gradually become one of the hotspots of scientific research. It is easy to be affected by the environment, and there are detection blind spots, etc. Therefore, it is imminent to develop new underwater sensors. The lateral line is a kind of sensory organ unique to fish and juvenile amphibians. It can perceive dynamic changes such as water flow in complex biological environments, and perceive the surrounding environment and targets by analyzing the changes in flow field stimulus information, so as to reproduce, prey, avoid, and so on. Behaviors such as ...
