Abstract
A liquid transportation device includes a working board, a working liquid, a liquid channel and a cover board, wherein the liquid channel is formed on a top surface of the working board, the covering board is fully covered the liquid channel, the liquid channel composed of a material substantially tending to the liquid, and the covering board is composed of a material substantially phobic to the liquid. The working liquid flows within the liquid channel in guidance of the deviation of surface tension between the liquid channel to the working liquid, and the covering board to the working liquid, so that the working liquid is transported within the liquid channel without any external power.
