Design and Optimization of Fiber Optic Grating Pressure Sensing Array

Abstract Aiming at the haptic problem of robot hand pressure, this paper studies a fiber grating tactile sensor array. Using polydimethylsiloxane (PDMS) package, and the finite element simulation of the package body to obtain internal strain. Aiming at the strain field distribution when the robot hand is gripping, the design of preliminary sensor array and finite element analysis are carried out, and the improved particle swarm algorithm is used to further optimize the measurement points. It provides a theoretical basis for the subsequent construction of the measurement points of the FBG tactile sensor array detection system.
