Full TextAbstract
This article investigates the effect of a micro-channel width and height on the threshold voltage for the movement of a liquid metal droplet in the electrowetting on dielectric (EWOD) phenomenon. For this purpose, a PCB (printed circuit board) board composed of an electrode array with a crescent shape is used. The micro-channel is covered from the top with a glass which is made conductive of electricity using the FTO technique. The results show that increasing the height and width of the micro-channel reduces the threshold voltage. The same trend is observed using an electrode curved with an opposite curvature. It is found that for an electrode shape curved with a curvature in the same direction of the droplet meniscus, the threshold voltage is lower.
