摘要：Non-contact transportation is used to hold and manipulate planner objects who are fragile or surface sensitive. Near field acoustic levitation is an important principle in non-contact transportation. The major advantages lie in magnet free, compact structure as well as sufficient load capacity. We studied the acoustic impedance matching method of a noncontact system driven by near field acoustic travelling waves. The influences on the levitation performance were also studied. The experimental measurements verified our theoretical results. We have also derived several design rules based on the impedance matching. These will be used in manufacturing of MEMS, IC or PV industry.
