Magnetostriction behavior modeling of magnetorheological foam using data-driven neural network algorithm

Magnetorheological (MR) foam is a magnetic polymer composite (MPC) that has the potential to be used for the application of soft sensors and actuators in robotics due to its tuneable mechanical properties and magnetostriction. Material development has recently become challenging since it is both tim...
