Progress in Developing Smart Magnetic Materials for Advanced Actuator Solutions

摘要

Solid state actuators based on smart magnetic materials have received considerable interest over the last years because of their fast frequency response, high energy efficiency and in many cases large stroke and force output. Although this class of smart material offers new options that cannot be addressed with traditional actuator technologies, there is still progress going on in developing optimum material properties and production processes. The recent developments in materials and production technologies as well as new actuator concepts are presented in this review paper, with a focus on magnetic shape memory materials and actuators.
