Abstract: With the diamagnetic material property, diamagnetic levitation possesses the special advantages of passive static and stable levitation at room temperature, which has attracted many scholars. Especially in the recent three decades, with the development of strong magnetic field equipment and micro technology, increasing publications on diamagnetic levitation research are appearing. Many foreign researches have done the relative investigations; however, the domestic researches in this field are relatively few and narrow. Aimed at this situation, a review of diamagnetic levitation technology including diamagnetic theory, diamagnetic characteristics and relative application research works is presented. The diamagnetic levitation technology not only possesses free-contact, no-lubrication and low energy consumption merits, but also permits advantages such as passive static and stable levitation at room temperature, micro-nano application and low supporting stiffness, which may possess potential and promising application ranging from micro rotating machinery, energy harvesting, high sensitive MEMS-sensor to cell/particle manipulation. A review of diamagnetic levitation is provided, which is helpful for the domestic researchers.
