摘要：
We investigate the applicability of measuring surface tension of liquid microdroplets by analyzing their oscillatory behavior induced by droplet collision. The eigenfrequency of droplet oscillation reflects surface tension for small-amplitude oscillation. In this study, the oscillation frequencies of ethanol-ethanol and water-water droplet collisions are measured by direct observation. We experimentally verify that surface tension can be measured for deformation smaller than 10% of the droplet radius. The collision between ethanol-water droplets is also analyzed. The eigenfrequency induced by unlike-droplet collision exhibits a peculiar behavior, which may be attributed to the temporal hybrid structure of a combined droplet.
