A controlled massage head is designed to vary the massage intensity rapidly. It bases on the property of magnetorheological fluid stiffness influenced by magnetic field. In this paper, we draw on relevant methods, design electromagnetic structures with numerical analysis software. The method of positive and negative current with permanent magnet compensation is presented to achieve a bigger range of magnetic field strength adjustment. Further, the massage head prototype is manufactured and tested. The experiment data are processed and indicates the design of the magnetic field strength and massage strength can meet the requirements.
