Underwater bionic lateral line sensing array

Abstract

An underwater bionic lateral line sensing array includes a bionic lateral line array structural body, runner water holes, an inner channel and a plurality of water current and water pressure compositesensors, wherein each water pressure composite sensor includes cilia made of electric reactive polymer smart material, a pressure transducer, electrodes and a pedestal. The bionic lateral line arraystructural body is therein provided with the inner channel in the length direction. The water current and water pressure composite sensors are arranged in the inner channel. The runner water holes communicating with the inner channel are arranged in one side of the bionic lateral line array structural body. The pedestals are arranged in the inner channel. Four electrodes are arranged on each pedestal. Each pedestal is provided with the cilia made of electric reactive polymer smart material and the pressure transducer is arranged on the pedestal. The underwater bionic lateral line sensing arrayhas a fish lateral line simulating system and senses water current and water pressure change at the same time, is high in anti-interference capability, high in sensibility and precision, and can provide measurement basis for accurate sensing of water environment change in the surrounding of a lateral line system.

Description

technical field [0001] The invention relates to the technical field of acquisition of new underwater water flow and water pressure signals, in particular to an underwater bionic lateral line sensing array. Background technique [0002] The ability of fish to be highly flexible and maneuverable in water is fundamentally derived from their well-developed lateral line perception system. By sensing changes in the surrounding environment, they can extract useful information and easily avoid obstacles and dangers. The lateral line system of fish has inspired the thinking of scientists. The artificial lateral line system mimics the perception of the environment by the lateral line of fish. The perception research of the artificial lateral line system has great scientific research value and practical application value. [0003] Fish perceive external stimuli through the excursion of neurons and transmit them in the form of electric current. It is a biological process integrating me...

Problems solved by technology

These studies can perceive the changing fluid around them through the sensing system, and can perceive the fluid information and estimate the direction and speed of the fluid, but there is still a big gap from the real fish sideline, and its stability and accuracy need to be further guaranteed
