许多世纪以来，鸟类或昆虫的飞行一直吸引着学者和物理学家。拍打运动，如许多自然飞行器所示，是飞行尺寸小于6英寸的物体的最有效方式。本文采用MEMS技术制作扑翼。它们由纯聚对二甲苯右翼和PVDF-聚对二甲苯复合左翼组成。在风洞试验中，来自PVDF（聚偏氟乙烯）和测压元件的升力信号具有相似的定性行为。PVDF传感器只能从左翼输出升力信号。通过与风洞测力传感器测得的总升力信号比较，可以计算出左、右翼对升力的贡献，并将其分离。因此，我们找到了一种新的设计方法来调整气动性能的微型飞行器通过微调的机构连杆改变两个扑翼之间的相位滞后。将锂电池集成到MAV后，它可以进行10-15米范围的自由飞行。最后，MAV通过无线控制成功飞行，航程为40 m，总飞行时间为10 s。(c)2007 Elsevier B.

The flight of birds or insects has fascinated scholars and physicists for many centuries. Flapping motion, as shown by many nature flyers, is the most efficient way of flying objects whose size are smaller than 6 in. In this paper, we used MEMS technology to fabricate the flapping wings. They are composed of a pure parylene right wing and a PVDF-parylene composite left wing. In the wind-tunnel test, the lift signals from both PVDF (polyvinylidene fluoride) and the load-cell have similar qualitative behavior. The PVDF sensor could only export the lift signals from the left wing. By comparing to the total lift signal picked by the load-cell from the wind-tunnel facility, we can calculate out and separate the lift contributions by left and right wing, respectively. Therefore, we found a new design methodology to adjust the aerodynamic performance of MAV by changing the phase lag between the two flapping wings by fine tuning of the mechanism linkages. After integrating lithium battery into the MAV, it can perform a free flight with a range of 10-15 m. Finally, the MAV had a successful flight via wireless control with a range of 40 m and a total flight time of 10 s. (c) 2007 Elsevier B.V. All rights reserved.
