Abstract

A new method for transporting droplets is presented to avoid directive radiation of surface acoustic wave (SAW). An interdigital transducer (IDT) is fabricated on a 128°-YX LiNbO<subscript>3</subscript> piezoelectric substrate using microelectric technology. A droplet to be transported is placed on a steel ball, which is driven by SAW. The droplet on the steel ball is then transported together with the steel ball. 0.5ul red ink solution was successfully transported by help of the steel ball with 2 mm diameters at 30.9 dBm electric signal power. Color development reaction is also implemented by transporting reaction solution using presented method to a paper-based device. [ABSTRACT FROM AUTHOR]
