研制了能够在液体或凝胶中游动的磁性微机械。该微机械由外部旋转磁场驱动，具有螺旋形结构和永磁体。机器可以在雷诺数（Re）为10（-7）的条件下游动，并能够使用相同的原理穿过琼脂或牛组织样品。它们的奔跑行为取决于外场的频率和强度，以及周围的介质。这些机器在人体医学应用方面具有巨大的潜力。(C)2001 Elsevier Science B. V.保留所有权利。
Magnetic micro-machines capable of swimming through liquid or gel were fabricated. The micro-machines were driven by an external rotating magnetic field and featured a screw-shaped structure and permanent magnet. The machines could swim under condition of a Reynolds number (Re) of 10(-7) and were able to run through agar or a bovine tissue sample using the same principle. Their running behavior was dependent on the frequency and strength of the external field, and on the surrounding media. These machines have great potential for medical applications in the human body.
