Abstract
The present invention relates to a viscosity measuring method. More particularly, the present invention relates to a viscosity measuring method comprising: (i) a step of acquiring an image of a droplet in a static state without vibration; (ii) a step of using a vibrator to vibrate the droplet, and acquiring an image of a dynamic state in which the droplet is maximally extended in a horizontal direction or maximally extended in a vertical direction; (iii) a step of obtaining the static curvature change rate and the dynamic curvature change rate of the interface of the droplet from the images acquired in steps (i) and (ii); and (iv) a step of substituting the ratio of the static curvature change rate to the dynamic curvature change rate of the droplet interface into an interaction equation compensating for the vibrator, so as to obtain the viscosity of the droplet.
