在这项研究中，一种新的按需滴驱动机制，它使用的振荡气泡作为驱动器的建议，并通过考虑两个重要的设计参数，即，气泡的自由表面的距离和喷嘴尺寸，其可行性进行了研究。利用高速摄影技术捕捉的液滴喷射过程表明，这种致动机构具有有趣的特征，并且可能比传统的致动机构（热泡、压电等）具有一些优点。用于喷墨打印机中，例如喷射没有卫星液滴的液滴等。
In this study, a new drop-on-demand actuation mechanism, which uses an oscillating bubble as actuator is proposed and its feasibility is investigated via the consideration of two important design parameters, namely, bubble distance to free surface and nozzle dimension. The droplet ejection process captured using high-speed photography technique shows that such an actuation mechanism has interesting features and perhaps some advantages over the conventional ones (thermal bubble, piezoelectric, etc.) employed in inkjet printers such as the ejection of a droplet free of satellite droplets and others.
