磁気マイクロマシンの移動速度の周波数依存性

抄録

This paper is concerned with a magnetic micro machine driven by the alternating magnetic field. The magnetic micro machine swims like microscopic organisms in water. Frequency dependence of the micro swimming machine is investigated as a basic research for the development of micro robots which work in human blood vessels. The magnetic micro machine is composed of a small neodymium magnet and a polyethyleneterephthalate film. The locomotive behavior of the magnetic micro machine is analyzed by a three-dimensional motion analysis system It is found that the swimming velocity of micro machine depends on the frequency of the alternating magnetic field and the dimensions of the tail.
