Haptic based Biomechanical Applications of Magnetic Soft Actuator

Soft actuators feature superior mechanical compliance and functionality than traditional rigid materials. These soft actuation devices can be used for a wide range in response to external stimuli such as heat, light, solvent, or electric or magnetic field. Especially, soft magnetic actuators exhibit some advantages such as untethered control, rapid response, and high safety, in micro/nano scale manipulations and biomedical applications. Successful development of magnetic soft actuators would require a comprehensive understanding of the fundamental principle of magnetic actuation, as well as the physical properties and behavior of magnetic soft materials, in the design and fabrication, modeling and simulation, and actuation and control of magnetic soft materials and actuators. In miniaturized scale soft actuators used for biomedical applications, their identifications rely on their design, fabrication, applications, and demonstration. It shows that these studies can be applied to the clinically high innovative applications by improving functionality and reliability of smart haptic equipment and giving a set of design guidelines for optimal actuation performance of magnetic soft materials in the therapeutic/diagnostic-related biomedical fields. Herein, a design and utilization strategy for magnetic soft actuators may be made through a mixture of magnetic particles and non-Newtonian fluidic soft materials to make programmable, hardened, and adhesive reconfigurations of soft actuators.
