THE DROPLET POSITIONING DEVICE USING THE INDUCED CHARGE OF THE CHARGED DROPLET

摘要

The present invention relates to a droplet position tracking device using the induced charge of a charged droplet and, more specifically, to a device for tracking the position of a charged droplet using the generation principle of induced electricity of a substance having electric charge. The droplet position tracking device capable of tracking the position of a droplet having electric charge comprises: a droplet actuating part; a control part for controlling the charging and moving of the droplet by applying individual power to electrodes; a connection part for connecting the droplet actuating part and the control part; a current system for measuring the induced charge of the droplet existed in the droplet actuating part; and an operation part for estimating the position of the droplet by analyzing current information received from the current system. The droplet actuating part comprises: an oil layer in which the droplet transfers, and which minimizes gravity and friction when the droplet transfers; a charging layer positioned under the oil layer and preventing the friction when the droplet transfers; the multiple electrodes penetrating the charging layer to be arranged at the same height as the charging layer and arranged at a right angle to the bottom surface of the charging layer; and a tank-shaped housing for storing the oil layer and the charging layer.
