 The researchers have developed a prototype micro-actuator consisting of a laminate structure composed of magnetostrain responsive NIMN-GAR micro-particles sandwiched between two layers of polymer and a copper foil. This structure allows for the isolation of the particles while still allowing them to experience the full effect of the magnetic field. The particles were found to be able to produce a recoverable outer plane stroke of approximately 3%, which can be used to drive various applications such as micro-robotics, optical image stabilisation in cameras, and pumps for micro-fluidics.
