Design and optimization of magnetic particles embedded in PDMS membrane

A design and optimization of the magnetic particles embedded inside a flexible membrane and factors contributing to the membrane performance have been studied. In this work, Nickel (Ni) is used as magnetic particles and Polydimethylsiloxane (PDMS) is used for membrane material which is considered a matrix component of the flexible membrane. Ni particles with various particle sizes, arrangement and spaces between Ni particles are simulated by using Comsol Multiphysics 4.2. As a result, the optimum design of magnetic particles embedded in membrane for large deflection is by having circular shape membrane with low density of tiny magnetic particles in planar distribution. A preliminary simulation result has been also compared with the theoretical calculation to validate the analysis.
