| Outline of Final Research Achievements |
This research is aiming to figure out a systematic design procedure of sextuple 3D-magnetic tweezer that is utilizing magnetic levitation technique to achieve a non-contact magnetic force exertion to a micro-sized magnetic particle, which is effective for establishing a position control of a free-floating particle in medium or a measurement of mechanical property, such as stiffness, of a specimen cell on which the particle is attached. In order to satisfy a given specification which includes a strength, frequency and a size of workspace in which anisotropy of the generative force can be within a permissible value, a practical procedure to find a combination of proper material, tip shape and number of turns of excitation coils was determined. By using this procedure, a setup has been fabricated, and a semi-closed loop magnetic force control using a Hall element sensor mounted on each pole’s end side was applied. Obtained performance of the developed system was experimentally evaluated.
