Abstract

The invention discloses a bionic lateral line flow sensor. The sensor comprises a colloid top, a sensor shell and a polyvinylidene fluoride piezoelectric thin film; the colloid top comprises a top part of the colloid top and a first cylinder, the top part of the colloid top is located on the first cylinder, and the bottom area of the top part of the colloid top is smaller than that of the bottom face of the first cylinder; a first groove is formed in the bottom of the first cylinder, a second groove is formed in the bottom of the colloid top, the bottom area of the second groove is smaller than that of the first groove, and the first groove is communicated with the second groove; the sensor shell comprises a second cylinder shell and a protrusion, the protrusion is arranged on the top faceof the second cylinder shell, the size of the protrusion is matched with that of the first groove, and the sensor shell is fixedly connected with the colloid top; one end of the polyvinylidene fluoride piezoelectric thin film is inserted in the protrusion, and the other end of the polyvinylidene fluoride piezoelectric thin film is inserted in the second groove. The sensor is integrally designed and is convenient to install, and the structure is closer to a lateral line sensing unit for fishes.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a bionic lateral flow sensor. Background technique [0002] 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 acoustic current meter, Norway's Andrei current meter RCM-9 (Doppler acoustic current meter) and acoustic Doppler current profiler, particle imaging velocimeter PIV and so on. These meters have their own advantages and disadvantages. For example, the accuracy of the acoustic sensor will be affected by seawater temperature, salinity, suspended particles, acoustic scattering and multipath propagation, etc.; the accuracy of the optical sensor will be affected. Effect of sea turbidity. Furthermore, ...
