Study on Characteristics of Iron-Gallium Alloys Sheet Applied to Tactile Sensors

Tactile sensors play an important role in promoting the intelligent development of robots, and it is imperative to develop advanced tactile sensors using new intelligent sensitive materials. The new iron gallium alloy(Fe83Ga17) has the advantages of high tensile strength, good ductility, large magnetostriction and high electromechanical coupling efficiency. It can be used as a smart component of a magnetostrictive tactile sensor. In this paper, a COMSOL multiphysics simulation software is used to establish a cantilever beam model of a sheet-shaped iron-gallium alloy, and the change of the magnetic flux density of the beam under different magnetic field and forces is analyzed. Through the testing and exploration of the characteristics of iron gallium alloy materials, its applicability as the core transducer component of the magnetostrictive tactile sensor is determined, which laid the foundation for better design and optimization of the magnetostrictive tactile sensor and improving the output performance of the sensor.
