Finite element analysis of characteristic array SU-8 based hair cell and cantilever beam for artificial lateral line flow sensor

This paper presents the analysis of modeling for artificial lateral line flow sensor. An artificial hair cell sensor is the current technology that based on a biological inspiration and widely used in underwater applications including glider, robotic and autonomous surface vehicle (ASV). The structure of the lateral line flow sensor is consisting of cantilever beam and four hair cells attached perpendicular to the cantilever beam at the free end. The lateral line sensor with different height of hair cells are modeled and simulated with water flow rate 0 m/s to 1 m/s. High sensitivity is achieved by increasing a hair cells length and use low young modulus material for a cantilever beam. The maximum stress was analyzed in order to identify the limitation of the sensor.
