Actuator and sensor technologies are essential in science and industry for the creation of robots, automobiles, and electric home appliances. In the Hirata Lab, we investigate next-generation actuator and sensor devices that adopt novel materials and operating principles, which include actuators with multiple degrees of freedom of movement that stand alone without coupling with other actuators, linear actuators designed to mimic the movement of human muscles, novel magnetic transmission mechanisms that allow the transmission of power without contact, magnetic fluids, giant magnetostrictive devices, thermosensitive magnetic materials, and nano ionic devices. Our research develops coupled-field analysis (multiphysics analysis) that combines an electromagnetic field with stress, temperature, or fluid using the finite element method and the particle method. We aim to elucidate the mechanisms responsible for physical phenomena of complex systems. The results are employed to optimize our design and develop prototypes, which are then tested to formulate an optimum control method.
