Abstract

The invention discloses a novel bionic lateral line sensor, which comprises a cilium housing, a cilium base rod, IPMC film sheets, extraction electrodes and a sensor housing. When an external flow acts on the free end of the cilium housing, the cilium housing generates mechanical deformation which can be transferred to the cilium base rod to cause deformation of the cilium base rod, deformation ofthe cilium base rod can lead to mechanical deformation of the IPMC film sheets, by using the IMC force electric effect, the IPMC film sheets can generate an induced voltage, and thus the magnitude ofthe external flow is calculated according to the collected induced voltage. The novel bionic lateral line sensor is adopted to be used for measuring the external flow, the cilium housing and cilium base rod are combined into one, the IPMC film sheets are used instead of strain gauges, and directly installed on the cilium base rod, the characteristics of integrated design, simple structure and convenient installation are achieved. Meanwhile, the novel bionic lateral line sensor can output the induced voltage accurately and obtain the flow velocity.

Description

technical field [0001] The invention relates to the field of underwater sensors, in particular to a novel bionic lateral line sensor. Background technique [0002] Ocean current measurement plays an important role in marine scientific research and engineering applications. Therefore, the study of new ocean current sensing technology has always been the focus of marine science and technology workers and marine engineering implementers. Marine organisms, especially fish, have a unique and highly sensitive sensory organ—the lateral line system, which can be used by fish to effectively perceive the surrounding ocean current field. [0003] Current sensors can be divided into mechanical propeller type, electromagnetic type, acoustic type and optical type according to the principle. Typical measuring instruments such as Uckmann current meter, S4 electromagnetic current meter produced by Interocean in the United States, and 2-D type by Falmouth Scientific Company Transit-time aco...
