Abstract: Magnetic microparticles find numerous applications as the end-effectors in micro-manipulation technologies. However stable control of these particles conventionally requires the use of visual feedback. Our lab recently proposed the use of micro-ring actuators and parametric excitation to stably trap and control magnetic micro-particles in three-dimensions (3-D). I will discuss the development of a linear time-invariant system model to describe the secular dynamics of such particles. Experimental validation of the model will be discussed for the case of a millimetre-sized particles whose magnetic moment is pointed upwards. The described model is subsequently extended for the study of the dynamics of arbitrarily oriented magnetic particles. I will conclude the talk with the future scope and potential applications of the proposed system.
