摘要

液滴操纵是SAW器件的重要应用之一。当液滴被放置在SAW装置上时,纵波辐射到液滴内。非线性声现象是由声呐的纵波辐射引起的。液滴操纵就是其中一种现象。研究声表面波控制液滴的最小辐射力是十分重要的。本文对液滴中的辐射力进行了实验测量。通过改变施加的电功率、水的体积和甘油-水混合物的浓度来测量辐射力。操作10微微的最小辐射力为0.168 mN。同时,利用高速摄像机对被操纵的水滴进行了观测。当纵波辐射到液滴内,且辐射力大于水的表面张力时,液滴的尖端向SAW传播方向延伸。换句话说,辐射力只作用于液滴的尖端。延长的长度取决于所施加的功率和占空比。液滴的其他部分起结合力的作用。力只作用于液滴的尖端,而液滴的末端被拖动。液滴操纵是SAW器件的重要应用之一。当液滴被放置在SAW装置上时,纵波辐射到液滴内。非线性声现象是由声呐的纵波辐射引起的。液滴操纵就是其中一种现象。研究声表面波控制液滴的最小辐射力是十分重要的。本文对液滴中的辐射力进行了实验测量。通过改变施加的电功率、水的体积和甘油-水混合物的浓度来测量辐射力。操作10微微的最小辐射力为0.168 mN。同时,利用高速摄像机对被操纵的水滴进行了观测。当纵波辐射到液滴内,且辐射力大于水的表面张力时,液滴的尖端向SAW传播方向延伸。换句话说,辐射力只作用于液滴的尖端。

Experimental considerations of droplet manipulation mechanism using surface acoustic wave devices
Droplet manipulation is one of the important application of the SAW device. When a droplet is placed on a SAW device, the longitudinal wave radiates into the droplet. Nonlinear acoustic phenomena are caused by the radiated longitudinal wave from the SAW. Droplet manipulation is one of those phenomena. It is important to investigate the minimum radiation force to manipulate the droplet by the SAW. In this paper, the radiation force in a droplet is experimentally measured. The radiation force was measured by varying an applied electrical power, water volume, and concentration of glycerol-water mixture. The minimum radiation force for manipulating 10 micro little was 0.168 mN. Also, the water droplet manipulated was observed by a high speed camera. When the longitudinal wave radiates into the droplet and the radiation force is larger than the surface tension of the water, the tip of the droplet is extended in the SAW propagation direction. In other words, the radiation force is acting only tip of the droplet. The extended length depends on the applied power and the duty factor. Other parts of the droplet act as binding force. The force only acts the tip of the droplet and the end part is dragged.Droplet manipulation is one of the important application of the SAW device.
