The acoustic levitation and transportation is widely used in the fields of the material preparation, the biochemical analysis and the advanced electronic manufacturing. The devices for that purposes often have a simple structure, can make flexible transportations, with a fast speed and a long distance, and enjoy a wide application range. The calculation methods of the acoustic radiation force, as the theoretical basis of the acoustic levitation and transportation, are reviewed; as well as the limitations of different methods with respect to the size of the object, the distance and the speed of the transportation; finally, some potential problems of the standing wave-traveling wave hybrid drive method in the acoustic levitation and transportation are analyzed and the potential applications of the acoustic levitation and transportation are prospected.
